Explanation: Acne vulgaris is a chronic inflammatory skin condition that affects the hair follicles and sebaceous glands. It is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and cysts. While it is not caused by a viral, bacterial, or fungal infection, it is associated with factors such as hormonal imbalances, increased sebum production, and inflammation of the hair follicles.

Incorrect choices: a. A viral skin infection - This is incorrect because acne vulgaris is not caused by a viral infection. It is primarily a result of the abnormal keratinization of hair follicles and excessive sebum production.

b. A bacterial skin infection - This is incorrect because although bacteria can play a role in the development of acne, it is not the primary cause. Propionibacterium acnes, a type of bacteria, is commonly found on the skin and can contribute to inflammation in acne lesions, but it is not the initial cause of acne.

d. A fungal skin infection - This is incorrect because acne vulgaris is not caused by a fungal infection. It is not related to fungi or yeast but is rather a disorder of the pilosebaceous unit in the skin.

Explanation: Acne vulgaris most commonly affects adolescents and young adults. It is estimated that up to 85% of individuals between the ages of 12 and 24 years experience acne at some point. During puberty, there is an increase in androgen hormones that can lead to an overproduction of sebum, leading to the development of acne.

Incorrect choices: a. Infants and young children - This is incorrect because acne vulgaris is rare in infants and young children. Acne in this age group may be a result of other underlying conditions and requires further evaluation by a healthcare provider.

c. Middle-aged adults - This is incorrect because acne vulgaris typically decreases with age. While some adults may still experience acne, it is less common compared to adolescents and young adults.

d. Elderly individuals - This is incorrect because acne vulgaris is rare in elderly individuals. It is more common in younger age groups due to hormonal changes and increased sebum production during adolescence and early adulthood.

Explanation: The primary cause of acne vulgaris is hormonal imbalances, specifically an increase in androgen hormones during puberty. Androgens stimulate the sebaceous glands to produce more sebum, which can clog the hair follicles and lead to the development of acne. While bacteria (Propionibacterium acnes) can contribute to inflammation in acne lesions, it is not the primary cause of acne.

Incorrect choices: a. Bacterial infection - This is incorrect because while bacteria can contribute to the inflammation seen in acne, it is not the primary cause. Acne develops due to the abnormal process of keratinization of hair follicles and increased sebum production.

c. Excessive sun exposure - This is incorrect because while excessive sun exposure can exacerbate some skin conditions, it is not the primary cause of acne vulgaris. In fact, mild sun exposure can sometimes improve acne temporarily, but excessive sun exposure can lead to other skin issues and should be avoided.

d. Allergic reactions to skincare products - This is incorrect because while allergic reactions to skincare products can cause skin irritation, redness, and rashes, it is not the primary cause of acne vulgaris. Acne develops due to hormonal factors and other underlying mechanisms in the skin.

Explanation: Acne vulgaris is a chronic inflammatory skin condition that affects the hair follicles and sebaceous glands. It is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and cysts. While hygiene and diet may play a role in acne development, they are not the sole causes. Acne is primarily influenced by hormonal factors, excessive sebum production, abnormal keratinization of hair follicles, and inflammation.

Incorrect choices: a. A skin condition caused by a lack of proper hygiene - This choice is incorrect because while proper hygiene is essential for maintaining skin health, acne is not solely caused by poor hygiene practices. Other factors like hormonal imbalances and inflammation play a more significant role in acne development.

b. A bacterial infection resulting from poor diet - This choice is incorrect because acne is not a bacterial infection caused by diet alone. While bacteria, particularly Propionibacterium acnes, are associated with acne lesions, the primary causes are related to hormonal changes and abnormal sebum production.

d. A viral skin infection transmitted through direct contact - This choice is incorrect because acne is not a viral infection and is not transmitted through direct contact. Acne is a non-communicable skin condition influenced by various internal and external factors, but not by a virus.

Explanation: The clinical manifestation described in option c (erythematous, raised plaques with silver scales) is not commonly seen in acne vulgaris. This description is characteristic of psoriasis, a chronic autoimmune skin condition. Acne vulgaris is characterized by the presence of comedones (blackheads and whiteheads), papules, pustules, nodules, and cysts on the skin, primarily affecting the face, neck, chest, and back.

Incorrect choices: a. Comedones (blackheads and whiteheads) - This choice is incorrect. Comedones are a hallmark clinical feature of acne vulgaris, and they occur when hair follicles become clogged with sebum and dead skin cells.

b. Papules and pustules - This choice is incorrect. Papules are small, red, inflamed bumps, while pustules are pus-filled lesions. Both are common manifestations of acne vulgaris.

d. Nodules and cysts - This choice is incorrect. Nodules and cysts are severe forms of acne vulgaris, characterized by larger, painful, and deeper lesions beneath the skin's surface. They are more likely to cause scarring and require medical intervention.

Explanation: The small, white bumps on the patient's forehead and chin are characteristic of closed comedones, also known as whiteheads. Comedones are non-inflammatory lesions and are one of the primary clinical manifestations of acne vulgaris.

Incorrect choices: a. Papules - Papules are small, red, inflamed bumps that may be present in acne vulgaris. However, they are not associated with the small, white bumps described in this question.

b. Pustules - Pustules are pus-filled lesions seen in acne vulgaris, but they are not the correct term for the small, white bumps in this scenario.

d. Nodules - Nodules are large, painful, solid lesions that extend deeper into the skin. They are not the correct term for the white bumps described in the question.

Explanation: Hormonal fluctuations, particularly an increase in androgen hormones during adolescence, play a significant role in the development of acne vulgaris. Androgens stimulate the sebaceous glands to produce more sebum, which can clog hair follicles and lead to the formation of acne lesions.

Incorrect choices: a. Bacterial infection - While bacteria, specifically Propionibacterium acnes, may contribute to the inflammation and worsening of acne lesions, it is not the primary cause of acne vulgaris.

b. Excessive sun exposure - Excessive sun exposure can exacerbate acne lesions, but it is not the primary cause of acne vulgaris.

d. Allergic reaction to cosmetics - Allergic reactions to cosmetics can cause skin irritation and rashes but are not the primary cause of acne vulgaris.

Explanation: Pustules are inflamed, tender, and pus-filled lesions commonly seen in acne vulgaris. They are a result of bacterial infection and inflammation within the blocked hair follicles.

Incorrect choices: a. Comedones - Comedones are non-inflammatory lesions that may be open (blackheads) or closed (whiteheads) and are not inflamed or pus-filled.

b. Nodules - Nodules are larger, solid, and painful lesions that extend deeper into the skin. They are more severe than pustules and papules.

c. Papules - Papules are small, red, inflamed bumps on the skin but are not pus-filled like pustules.

Explanation: The primary pathogenesis of acne vulgaris involves increased keratinization (abnormal skin cell turnover) and follicular plugging. Excess sebum production, along with dead skin cells and bacteria, can lead to the formation of comedones, which are a hallmark of acne vulgaris.

Incorrect choices: a. Excessive skin hydration - Excessive skin hydration is not the primary pathogenesis of acne vulgaris. In fact, excessive oil production contributes to the development of acne lesions.

c. Overproduction of melanin - Overproduction of melanin is not the primary cause of acne vulgaris. Melanin is responsible for skin pigmentation, but it does not directly contribute to acne formation.

d. Allergic reaction to environmental allergens - Acne vulgaris is not primarily caused by an allergic reaction to environmental allergens. While allergens can exacerbate skin conditions, they are not the underlying cause of acne vulgaris.

Explanation: The primary diagnostic criterion for acne vulgaris is the presence of comedones, which are non-inflammatory lesions that occur when hair follicles become clogged with sebum and dead skin cells. Comedones can be either open (blackheads) or closed (whiteheads) and are a hallmark of acne vulgaris.

Incorrect choices: b. Appearance of pustules - Pustules are inflammatory lesions seen in acne vulgaris, but they are not the primary diagnostic criterion.

c. Erythematous, raised plaques with silver scales - This description is characteristic of psoriasis, not acne vulgaris. Psoriasis is a chronic autoimmune skin condition.

d. Nodules and cysts on the skin - Nodules and cysts are severe forms of acne vulgaris, but they are not the primary diagnostic criterion. They may develop in later stages of the condition.

Explanation: The presence of a rash on the hands and feet is not a common diagnostic criterion for acne vulgaris. Acne vulgaris primarily affects the face, neck, chest, and back, and rashes on the hands and feet are not characteristic of this condition.

Incorrect choices: a. Family history of acne - A family history of acne is a relevant diagnostic criterion as there can be a genetic predisposition to developing acne.

b. Skin biopsy - A skin biopsy may be used in some cases to confirm the diagnosis of acne vulgaris and rule out other skin conditions with similar presentations.

d. Physical examination of the skin - Physical examination of the skin is a standard diagnostic approach for identifying acne vulgaris. It involves assessing the presence of comedones, papules, pustules, nodules, and cysts on the skin.

Explanation: The distribution of the lesions is a key diagnostic criterion used to differentiate acne vulgaris from acne rosacea. Acne vulgaris commonly affects the face, neck, chest, and back, while acne rosacea typically presents with erythema (redness) and affects the central areas of the face, such as the cheeks and nose.

Incorrect choices: a. Presence of comedones - The presence of comedones is common in both acne vulgaris and acne rosacea, and it does not help differentiate between the two conditions.

b. Age of the patient - While age can provide some clues, it is not a definitive diagnostic criterion as both acne vulgaris and acne rosacea can affect individuals of different age groups.

d. Severity of skin redness - The severity of skin redness is a characteristic of acne rosacea, but it alone does not differentiate it from acne vulgaris. The distribution of lesions is more specific for distinguishing between the two conditions.

Explanation: The description of small, red, inflamed bumps on the face and back is consistent with papules, which are a common clinical manifestation of acne vulgaris.

Incorrect choices: a. Presence of nodules and cysts - Nodules and cysts are deeper, larger, and more severe lesions that extend into the skin. They are not characteristic of the small, red, inflamed bumps described.

b. Appearance of comedones - Comedones are non-inflammatory lesions and do not present as red, inflamed bumps.

c. Distribution of pustules - Pustules are pus-filled lesions, and the description of the patient's skin lesions does not specifically mention pustules.

Explanation: The diagnostic criteria for acne vulgaris typically include the identification of both comedones (blackheads and whiteheads) and inflammatory lesions (papules, pustules, nodules, and cysts). These manifestations are characteristic of acne vulgaris and help distinguish it from other skin conditions.

Incorrect choices: a. Scalp lesions - Scalp lesions are not specific to acne vulgaris and may be associated with other skin conditions or scalp disorders.

b. Yellowish-brown nodules - Yellowish-brown nodules are not commonly associated with acne vulgaris. These nodules may indicate a different skin condition.

c. Erythematous plaques with silver scales - This description is characteristic of psoriasis, a chronic autoimmune skin condition, and is not indicative of acne vulgaris.

Explanation: Choice b is correct because non-comedogenic makeup products are formulated not to clog pores, which can help prevent further acne breakouts. Other makeup products may contribute to pore blockages and exacerbate acne.

Incorrect choices: a. "Apply oil-based moisturizers to keep the skin hydrated." - Oil-based moisturizers can be heavy and may contribute to clogged pores, worsening acne in some cases.

c. "Exfoliate the skin daily to remove dead skin cells." - Daily exfoliation can irritate the skin and may lead to increased inflammation and breakouts. Gentle exfoliation, no more than two to three times per week, is recommended.

d. "Use hot water to wash your face for better results." - Hot water can strip the skin of its natural oils and lead to dryness and irritation. Lukewarm water is preferable for cleansing the face to avoid exacerbating acne symptoms.

While some medications for acne (like retinoids) can increase sensitivity to the sun, and sun exposure can worsen acne or lead to hyperpigmentation, this is a beneficial recommendation.

Incorrect choices:

a. Squeezing and popping acne lesions to release pus. - This intervention can lead to infection and scarring, as well as exacerbate inflammation and further spread bacteria.

b. Recommending the use of abrasive facial scrubs daily. - Daily use of abrasive facial scrubs can irritate the skin and worsen acne symptoms. Gentle cleansing is preferred for individuals with acne-prone skin.

d. Applying over-the-counter hydrocortisone cream to the affected areas. - Hydrocortisone cream is a topical steroid and is not recommended for routine use on acne lesions. It may cause skin thinning and other side effects if used improperly.

Explanation: Choice c indicates a need for further teaching because applying a thick layer of moisturizer before bedtime can potentially clog pores and worsen acne. While moisturizing is essential for preventing dryness, it is essential to use non-comedogenic, oil-free moisturizers that are suitable for acne-prone skin.

Incorrect choices: a. "I will cleanse my face with a mild, non-soap cleanser twice a day." - This statement is correct as cleansing the face with a mild, non-soap cleanser twice a day helps remove dirt, excess oil, and debris without drying out the skin excessively.

b. "I will use a topical retinoid as prescribed by my healthcare provider." - This statement is correct as topical retinoids are a common treatment for acne vulgaris and help promote skin cell turnover and prevent clogged pores.

d. "I will avoid picking or squeezing acne lesions to prevent scarring." - This statement is correct as picking or squeezing acne lesions can lead to infection, inflammation, and scarring.

Explanation: Regular monitoring of liver function is essential for clients receiving oral antibiotics for acne vulgaris because some antibiotics may have the potential to cause hepatotoxicity (liver damage). Monitoring liver function helps detect any adverse effects and ensures the client's safety during treatment.

Incorrect choices: a. Encourage the client to avoid consuming dairy products during antibiotic treatment. - There is no specific evidence that links dairy consumption with the effectiveness of oral antibiotics for acne vulgaris. Dairy restriction is not typically indicated for clients on acne treatment.

b. Educate the client on the importance of sun exposure for vitamin D synthesis. - While sun exposure can contribute to vitamin D synthesis, it is not specifically relevant to the client's treatment with oral antibiotics for acne vulgaris. In fact, sun exposure should be minimized or accompanied by sunscreen due to the potential for photosensitivity caused by some antibiotics.

d. Recommend the use of topical benzoyl peroxide in combination with oral antibiotics. - This may be a valid treatment option; however, the question specifically asks for a nursing management action related to the oral antibiotics. The nurse's responsibility is to monitor the client's response to the prescribed oral antibiotics and potential side effects, not topical treatment recommendations.

Explanation: The nurse's role in addressing the client's concern about potential scarring is to provide emotional support and encouragement. Acne can have a significant impact on self-esteem, especially in teenagers. Encouraging open communication and offering support can help the client cope with the emotional aspect of acne and its potential effects on self-image.

Incorrect choices: a. Apply a topical retinoid liberally to prevent scarring. - While topical retinoids are used in the treatment of acne vulgaris, they are not specifically applied to prevent scarring. Their primary role is to promote skin cell turnover and prevent clogged pores.

Explanation: Scabies can affect various areas of the body, but the genital area is a common site of infestation, especially in adults.

Incorrect choices:

a. Scalp: While scabies can occur on the scalp, it is less common than other areas of the body.

b. Elbows: Scabies can occur on the elbows, but it is not a common site of infestation.

d. Sole of the feet: Scabies can occur on the sole of the feet, but it is not a common site of infestation, especially in adults.

Explanation: Scabies is diagnosed by taking a skin scraping from the affected area and examining it under a microscope to identify the presence of the scabies mite or its eggs.

Incorrect choices:

a. Blood test: Scabies is not diagnosed through a blood test. Skin scraping is the preferred method.

b. X-ray: X-ray is not used to diagnose scabies. It is not a suitable method for identifying the mite.

d. Urine analysis: Urine analysis is not used to diagnose scabies. Skin scraping is the standard method for diagnosis.

Explanation: The primary intervention for treating scabies is the use of topical scabicide medications. These medications kill the scabies mites and their eggs, effectively treating the infestation.

Incorrect choices:

a. Applying corticosteroid creams: Corticosteroid creams are used to relieve inflammation and itching but do not treat the underlying scabies infestation.

b. Warm compresses: Warm compresses may temporarily relieve itching but do not eliminate the scabies mites.

c. Over-the-counter antifungal creams: Over-the-counter antifungal creams are not effective in treating scabies, as scabies is caused by a mite, not a fungus.

Explanation: Contact precautions are important for individuals diagnosed with scabies infestation. These precautions involve the use of gloves and gowns to prevent the spread of the mites through direct contact with the person or infested items.

Incorrect choices:

a. Isolation precautions: Isolation precautions are not necessary for scabies infestation. Contact precautions are sufficient.

b. Droplet precautions: Droplet precautions are used for diseases spread by respiratory droplets, not scabies.

d. Airborne precautions: Airborne precautions are used for diseases spread by small particles suspended in the air, not scabies.

Explanation: Scabies infestation can be treated with permethrin cream, which is a topical scabicide that kills the scabies mites and their eggs.

Incorrect choices:

a. Oral antibiotics: Oral antibiotics are not effective in treating scabies, as it is not caused by bacteria.

b. Topical antifungal creams: Topical antifungal creams are not effective in treating scabies, as

scabies is caused by a mite, not a fungus.

c. Bed rest and hydration: Bed rest and hydration are essential for overall health but do not directly treat the scabies infestation.

Explanation: Frequent handwashing is an essential preventive measure for scabies infestation. It helps reduce the risk of acquiring the mites through indirect contact with infested items.

Incorrect choices:

a. Avoiding contact with animals: Scabies is not typically transmitted from animals to humans. It is primarily spread through direct skin-to-skin contact with an infected person.

b. Using insect repellent: Insect repellent is not effective in preventing scabies infestation, as it is caused by a mite, not insects.

d. Avoiding crowded places: While avoiding crowded places may reduce the risk of some infections, it does not specifically prevent scabies infestation. Direct contact with an infected person or infested items is the primary mode of transmission.

Explanation: If one member of a household is diagnosed with scabies, all household members should be treated with scabicide medications to prevent the spread of the infestation.

Incorrect choices:

a. Isolate the infected individual in a separate room: While contact precautions are recommended for the infected individual, isolating them in a separate room is not necessary.

c. Wash all household linens in hot water: Washing linens in hot water is recommended to reduce the risk of mites surviving on infested items, but treatment with scabicide medications is the primary preventive measure.

d. Wear personal protective equipment around the infected individual: Contact precautions, including wearing gloves and gowns, are recommended for healthcare providers but not necessarily for household members. Treating all household members is the most effective preventive measure.

Explanation: Psoriasis is an autoimmune skin disorder where the immune system mistakenly attacks healthy skin cells, leading to the rapid buildup of skin cells and the formation of red, scaly patches on the skin's surface.

Incorrect choices: a. A contagious bacterial skin infection - Psoriasis is not caused by bacteria, and it is not contagious.

c. A fungal infection causing itching and rash - Psoriasis is not caused by a fungus; it is an autoimmune condition.

d. A viral skin condition resulting in fluid-filled blisters - Psoriasis does not result in fluid-filled blisters; it presents as red, scaly patches instead.

Explanation: Psoriasis commonly presents as red, scaly, and thickened patches on the skin. These patches can be itchy, painful, and sometimes crack and bleed.

Incorrect choices: a. Smooth and pink patches on the skin - This is not characteristic of psoriasis, which typically involves scaling and thickening of the skin.

b. Flaky, white patches on the skin - This is not typical of psoriasis; the patches are usually red and scaly.

d. Raised, flesh-colored bumps on the skin - This description does not match the typical appearance of psoriasis patches.

Explanation: Psoriasis is believed to have a genetic component, and it is considered an autoimmune disorder where the immune system mistakenly attacks healthy skin cells, leading to the characteristic skin changes.

Incorrect choices: a. Poor hygiene and lack of skin care - Psoriasis is not caused by poor hygiene or lack of skin care.

b. Exposure to environmental toxins - While environmental factors may trigger or worsen psoriasis in some individuals, they are not the primary cause of the condition.

d. Excessive sun exposure - Sun exposure may improve psoriasis symptoms in some people, but it is not the underlying cause of the condition.

Explanation: Psoriasis commonly affects the scalp, leading to the formation of red, scaly patches on the scalp's surface. It can also extend to the hairline and behind the ears.

Incorrect choices: b. Soles of the feet - Psoriasis can affect the soles of the feet, but it is less common than scalp involvement.

c. Abdomen - Psoriasis can occur on the abdomen, but it is not as frequently affected as the scalp.

d. Neck - Psoriasis can involve the neck area, but it is not the most common site of involvement.

Explanation: The primary etiological factor in psoriasis is a genetic predisposition. Psoriasis has a strong hereditary component, and individuals with a family history of the condition are at a higher risk of developing it. While environmental triggers can exacerbate psoriasis symptoms, the condition itself is primarily influenced by genetic factors.

Incorrect choices: a. Bacterial infection: Psoriasis is not caused by a bacterial infection. It is an autoimmune condition characterized by an overactive immune response, leading to inflammation and skin cell overproduction.

b. Fungal overgrowth: Fungal overgrowth is not a cause of psoriasis. Psoriasis is not related to fungal infections and has a different underlying mechanism.

d. Allergic reaction: While certain allergens may exacerbate psoriasis symptoms in some individuals, an allergic reaction is not the primary cause of psoriasis. The condition's pathophysiology is rooted in immune system dysfunction rather than allergic responses.

Explanation: Psoriasis is an autoimmune disorder in which T-cells, a type of white blood cell, become overactive and trigger an inflammatory response. These T-cells promote the rapid growth of skin cells, leading to the characteristic plaques seen in psoriasis.

Incorrect choices: b. B-cells: While B-cells are important components of the immune system, they are not primarily involved in the etiology of psoriasis. T-cells are the central players in the autoimmune response seen in psoriasis.

c. Platelets: Platelets are primarily responsible for blood clotting and are not directly related to the development of psoriasis.

d. Eosinophils: Eosinophils are a type of white blood cell involved in immune responses against parasitic infections and allergic reactions. While they are important in certain immune processes, they are not the main players in psoriasis etiology.

Explanation: Environmental factors such as stress, trauma, infections, and certain medications are considered triggers that can worsen psoriasis symptoms in individuals who are already genetically predisposed to the condition. These triggers can lead to psoriasis flare-ups or worsen existing plaques.

Incorrect choices: a. Primary cause of psoriasis: Environmental factors are not the primary cause of psoriasis. While they can influence the severity of symptoms, the condition itself is primarily driven by genetic factors and immune system dysfunction.

b. Minor role with no significant impact: Environmental triggers are not minor in psoriasis etiology. They can have a significant impact on symptom severity and recurrence in susceptible individuals.

d. Protective factors against developing psoriasis: Environmental factors are not protective against developing psoriasis. As an autoimmune condition, psoriasis is primarily influenced by genetic predisposition and immune system dysfunction, not by protective environmental factors.

Explanation: Psoriasis is an autoimmune disorder characterized by an overactive immune system. In psoriasis, the immune system mistakenly triggers inflammation, leading to the rapid growth of skin cells and the formation of plaques.

Incorrect choices: a. Immune system suppresses inflammation and skin cell proliferation: This statement is incorrect. In psoriasis, the immune system does not suppress inflammation but rather promotes it.

b. Immune system responds normally to environmental triggers: This statement is incorrect. In psoriasis, the immune system's response to triggers is abnormal, leading to the characteristic inflammation and skin cell overgrowth.

d. Immune system functions independently of psoriasis development: This statement is incorrect. The immune system plays a central role in psoriasis etiology. The abnormal immune response is the driving force behind the development and progression of psoriasis.

Explanation: Genetic predisposition in psoriasis contributes to the development of the condition by causing abnormal functioning of the immune system. Certain genes involved in the immune response are associated with psoriasis, leading to an overactive immune system that triggers inflammation and skin cell overproduction.

Incorrect choices: a. Genetic factors increase skin sensitivity to environmental irritants: While some environmental triggers can worsen psoriasis symptoms, genetic predisposition primarily influences the immune system's response, not skin sensitivity to irritants.

b. Genetic factors cause an allergic reaction to certain foods: Psoriasis is not primarily an allergic reaction, and genetic factors do not cause allergic reactions to specific foods in this context.

d. Genetic factors impair the skin's barrier function: Psoriasis is not caused by a skin barrier dysfunction. The condition is characterized by immune system dysregulation and the subsequent inflammation and rapid skin cell turnover.

Explanation: Psoriasis is characterized by the presence of itchy, raised, red patches on the skin with silvery scales. These patches are known as plaques and are a hallmark feature of psoriasis.

Incorrect choices: a. Painful, deep ulcers on the skin: This description does not align with psoriasis. Psoriasis plaques are not typically painful or ulcerated.

c. Small, fluid-filled blisters on the palms and soles: This description is more characteristic of a condition called palmoplantar pustulosis, not psoriasis.

d. Thickened, hardened skin with deep cracks: This description is more typical of a condition called lichenified eczema or chronic contact dermatitis, not psoriasis.

Explanation: Psoriasis commonly affects the scalp and nails in addition to other areas of the body. Scalp psoriasis can cause flaking and scale buildup on the scalp, while nail psoriasis can lead to pitting, discoloration, and thickening of the nails.

Incorrect choices: b. Buttocks and thighs: While psoriasis can occur in these areas, it is not one of the most common areas affected.

c. Lower back and shoulders: These areas can be affected by psoriasis, but they are not the most commonly affected regions.

d. Upper arms and neck: Psoriasis can occur on the upper arms and neck, but it is not the most frequently affected area.

Explanation: Fatigue and malaise are common symptoms experienced by individuals with psoriasis. The chronic inflammation and immune system dysregulation in psoriasis can lead to feelings of tiredness and general discomfort.

Incorrect choices: a. Persistent fever and chills: Fever and chills are not typical symptoms of psoriasis. They may indicate an infection or other underlying health condition.

b. Frequent nosebleeds: Nosebleeds are not directly associated with psoriasis. They may be caused by other factors such as nasal dryness or irritation.

d. Excessive thirst and frequent urination: These symptoms are not typically related to psoriasis. They may be indicative of diabetes or other medical conditions.

Explanation: Psoriasis lesions commonly appear in a symmetrical pattern, affecting similar areas on both sides of the body. For example, if a plaque is present on the right elbow, there is a high likelihood of a corresponding plaque on the left elbow.

Incorrect choices: a. Psoriasis lesions are evenly distributed across the body: Psoriasis lesions are not evenly distributed and tend to cluster in certain areas, such as elbows, knees, scalp, and lower back.

b. Psoriasis lesions are typically limited to the face and neck: While psoriasis can occur on the face and neck, it is more commonly found on extensor surfaces (elbows and knees) and the scalp.

c. Psoriasis lesions are more commonly found on the left side of the body: There is no evidence to support a preference for the left side of the body in psoriasis distribution. The symmetrical pattern is a more characteristic feature.

Explanation: Chronic psoriasis is characterized by thickened, scaly plaques with silvery-white scales. These plaques result from the excessive growth and turnover of skin cells in psoriasis.

Incorrect choices: a. Generalized redness with no scaling: This description does not align with chronic psoriasis. Psoriasis plaques are typically scaly and have a characteristic appearance.

b. Pustules and fluid-filled blisters: Pustular psoriasis is a specific subtype of psoriasis characterized by pustules, but it is not a hallmark of chronic psoriasis.

c. Hyperpigmented patches with rough texture: Hyperpigmentation and rough texture are not typical features of chronic psoriasis. The characteristic feature is the presence of silvery-white scales on thickened plaques.

Explanation: The presence of at least 3 typical psoriasis plaques on the body is one of the essential diagnostic criteria for confirming psoriasis. These plaques are characterized by well-defined, erythematous (red), raised lesions with silvery-white scales.

Incorrect choices: a. Positive skin biopsy showing eosinophils infiltration: While a skin biopsy may be performed to support the diagnosis of psoriasis, the presence of eosinophils is not specific to psoriasis and can be found in various skin conditions.

b. Family history of autoimmune diseases: A family history of autoimmune diseases may increase the risk of developing psoriasis, but it is not a definitive diagnostic criterion for the condition.

d. Elevated erythrocyte sedimentation rate (ESR) on blood test: An elevated ESR can indicate inflammation in the body, but it is not specific to psoriasis and may be present in other inflammatory conditions as well.

Explanation: The Auspitz sign refers to the appearance of tiny bleeding points when the scales on psoriatic plaques are removed or scraped. This sign is a characteristic feature of psoriasis and helps differentiate it from other skin conditions.

Incorrect choices: a. Moist, oozing skin lesions: Moist, oozing lesions are not typical of psoriasis. Psoriasis plaques are dry and scaly in nature.

b. Dark, hyperpigmented patches: Hyperpigmentation is not a characteristic feature of psoriasis. Psoriatic plaques are typically erythematous (red) with silvery-white scales.

d. Translucent, fluid-filled blisters: Translucent, fluid-filled blisters are not typically associated with psoriasis. This description is more consistent with a condition called pemphigus, not psoriasis.

Explanation: A skin biopsy is commonly performed to confirm the diagnosis of psoriasis. It involves taking a small sample of skin tissue from a psoriatic plaque and examining it under a microscope to identify the characteristic histological changes, such as hyperkeratosis, parakeratosis, and elongation of the rete ridges.

Incorrect choices: a. Skin patch testing for allergens: Patch testing is used to diagnose allergic contact dermatitis, not psoriasis.

b. Chest X-ray to assess lung involvement: Chest X-rays are not necessary for the diagnosis of psoriasis, as it primarily affects the skin and joints, not the lungs.

c. Complete blood count (CBC) to assess white blood cell count: While a CBC may be performed to assess inflammation, it is not specific to psoriasis and cannot confirm the diagnosis. A skin biopsy is needed for definitive diagnosis.

Explanation: The development of wheals and hives is not characteristic of psoriasis. Wheals and hives are associated with urticaria (hives), which is a separate skin condition caused by histamine release.

Incorrect choices: a. Pitting and ridging of the nails: Pitting and ridging of the nails are common nail changes seen in psoriasis and can aid in its diagnosis.

b. Koebner phenomenon upon skin trauma: The Koebner phenomenon, where new psoriatic lesions form at sites of skin trauma or injury, is a characteristic feature of psoriasis.

d. Silvery-white scales on erythematous plaques: Silvery-white scales on erythematous (red) plaques are a classic feature of psoriasis and help differentiate it from other skin conditions.

Explanation: Plaque psoriasis is the most common type of psoriasis, accounting for approximately 80-90% of all cases. It is characterized by the presence of raised, well-defined, erythematous (red) plaques with silvery-white scales.

Incorrect choices: a. Guttate psoriasis: Guttate psoriasis is characterized by small, teardrop-shaped lesions scattered on the skin, often following a streptococcal infection. It is less common than plaque psoriasis.

b. Inverse psoriasis: Inverse psoriasis affects skin folds, such as the armpits, groin, and under the breasts. It appears as smooth, red patches and is less common than plaque psoriasis.

d. Pustular psoriasis: Pustular psoriasis is a specific subtype characterized by pustules on the skin, but it is less common than plaque psoriasis.

Explanation: Applying topical corticosteroids to affected areas can help reduce inflammation, itching, and discomfort associated with psoriasis. However, the nurse should ensure that the patient follows the prescribed dosage and instructions for the use of corticosteroids.

Incorrect choices: b. Encouraging the patient to scratch the affected areas gently is not appropriate, as scratching can exacerbate psoriasis and lead to skin damage and infection.

c. NSAIDs are not typically used to manage itching and discomfort in psoriasis. They may be prescribed for joint pain associated with psoriatic arthritis, but they do not target the skin symptoms of psoriasis.

d. While warm baths can be soothing, frequent baths may actually dry out the skin and worsen psoriasis. Additionally, the water should be lukewarm rather than hot to avoid triggering flare-ups.

Explanation: Taking long, hot baths can actually worsen psoriasis by drying out the skin and triggering flare-ups. Instead, patients with psoriasis should take short, lukewarm baths or showers to avoid exacerbating the condition.

Incorrect choices: a. Moisturizing the skin regularly is an essential part of psoriasis management to prevent dryness and scaling.

b. Avoiding fragranced soaps and lotions can help minimize skin irritation and sensitivity, which is beneficial for patients with psoriasis.

c. Applying sunscreen before going outside is important, as exposure to UV rays can trigger or worsen psoriasis. Sun protection helps prevent further skin damage.

Explanation: Phototherapy involves exposing the skin to UV light to treat psoriasis. During phototherapy sessions, patients should wear special shields to protect their eyes and genitals from potential UV damage.

Incorrect choices: a. Patients undergoing phototherapy are actually exposed to controlled amounts of UV light, which is different from uncontrolled sun exposure. Phototherapy is a prescribed treatment and should be done under healthcare professional supervision.

b. While phototherapy may cause temporary skin darkening or tanning, it is not associated with permanent changes in skin color.

d. Phototherapy does not increase the risk of skin infections. However, patients with psoriasis should practice good hygiene to prevent infections related to their condition and skin care routine.

Explanation: Topical retinoids can increase the skin's sensitivity to sunlight and may cause sunburn. Patients should avoid excessive sun exposure and use sunscreen to protect their skin when using topical retinoids.

Incorrect choices: a. Topical retinoids should be applied to dry skin, not wet skin, to ensure proper absorption and effectiveness.

b. Topical retinoids are typically applied to the entire affected area, not just individual psoriasis plaques. They work best when applied consistently to the entire affected area.

c. Topical retinoids may take several weeks to show significant improvement in psoriasis symptoms, and immediate relief is not typical.

Explanation: Immunosuppressive medications can weaken the immune system, making the patient more susceptible to infections. It is important for the patient to promptly report any signs of infection or illness to their healthcare provider for appropriate management.

Incorrect choices: b. The administration of immunosuppressive medications is often specific to each medication and should be taken as prescribed by the healthcare provider, with or without food, as indicated.

c. Immunosuppressive medications can increase the risk of infections, but they do not directly increase the risk of sunburn. Patients should, however, be cautious about sun exposure due to potential skin sensitivity.

d. Discontinuing immunosuppressive medications abruptly can be dangerous and should only be done under the guidance of a healthcare provider. Sudden discontinuation can lead to worsening of psoriasis and potential rebound effects.

Explanation: Keeping the skin well-hydrated is essential in managing psoriasis. Patients should use fragrance-free moisturizers to prevent skin dryness and irritation, which can trigger flare-ups.
