A client diagnosed with contact dermatitis is receiving education from the nurse. Which of the following therapies will the nurse recommend to the client?

Phototherapy

Antibiotics

UV light

Avoidance

Answer and Explanation

The Correct Answer is D

Choice A Reason: This is incorrect because phototherapy is not a recommended therapy for contact dermatitis. Phototherapy involves exposing the skin to artificial light sources that emit specific wavelengths of light that can have anti-inflammatory or immunomodulatory effects. Phototherapy can be used for some skin conditions, such as psoriasis or eczema, but not for contact dermatitis.

Choice B Reason: This is incorrect because antibiotics are not a recommended therapy for contact dermatitis. Antibiotics are drugs that kill or inhibit bacteria that cause infections. Contact dermatitis is not an infection, but an allergic or irritant reaction to a substance that comes in contact with the skin. Antibiotics have no effect on contact dermatitis and may cause adverse effects or resistance.

Choice C Reason: This is incorrect because UV light is not a recommended therapy for contact dermatitis. UV light refers to ultraviolet radiation from sunlight or artificial sources that can damage DNA and cause skin cancer or aging. UV light can also worsen contact dermatitis by increasing inflammation and sensitivity to allergens or irritants.

Choice D Reason: This is correct because avoidance is the best therapy for contact dermatitis. Avoidance means identifying and avoiding the substance that causes the skin reaction. This can prevent further exposure and allow the skin to heal. The nurse can help the client by providing education on how to read labels, use protective clothing or gloves, or substitute safer products.

Correct Answer is B

Explanation

Choice A Reason: A virus is not detected by the KOH test, which is used to diagnose fungal infections of the skin, hair, or nails. A virus can be detected by other tests, such as polymerase chain reaction (PCR) or viral culture.

Choice B Reason: A fungal infection is detected by the KOH test, which dissolves the skin cells and leaves behind the fungal elements that can be seen under a microscope. A fungal infection can cause symptoms such as itching, scaling, redness, or blisters.

Choice C Reason: A bacterial infection is not detected by the KOH test, which is specific for fungi. A bacterial infection can be detected by other tests, such as gram stain or culture.

Choice D Reason: Cancer is not detected by the KOH test, which is not a screening tool for malignancy. Cancer can be detected by other tests, such as biopsy or imaging.

A. Minimal movement, verbal responses limited to sounds, awakens briefly only with extreme vigorous stimulation. B. Extremely drowsy, minimally responsive, limited ability to follow commands, vigorous stimulation needed to waken. C. Alert and oriented x3, sluggish, drowsy, wakes to voice or gentle shaking. D. Does not respond to verbal stimuli, does not speak, decorticate/decerebrate posturing in response to pain.

Correct Answer is A

Explanation

Choice A reason: This is the correct answer because this describes a stupor, which is a state of near-unconsciousness or reduced responsiveness. A stuporous client shows minimal movement and verbal responses and requires extreme vigorous stimulation such as painful stimuli to awaken briefly.

Choice B reason: This is incorrect because this describes obtundation, which is a state of reduced alertness or awareness. An obtunded client is extremely drowsy and minimally responsive and requires vigorous stimulation such as shaking or shouting to wake.

Choice C reason: This is incorrect because this describes lethargy, which is a state of decreased energy or activity. A lethargic client is alert and oriented x3 (to person, place, and time), but sluggish and drowsy, and wakes to voice or gentle shaking.

Choice D reason: This is incorrect because this describes a coma, which is a state of deep unconsciousness or unresponsiveness. A comatose client does not respond to verbal stimuli or speak and shows abnormal posturing in response to pain, such as decorticate (flexion of arms and extension of legs) or decerebrate (extension of arms and legs).
