The client inquires what the positive result from the potassium hydroxide (KOH) test indicates. Which of the following is an accurate response by the nurse?
You have a virus.
You have a fungal infection.
You have a bacterial infection.
You have cancer.
The Correct Answer is B
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.

Correct Answer is D
Explanation
Choice A reason: Resting in bed for at least 2 days is not necessary after cataract surgery. The client should resume normal activities as soon as possible, but avoid strenuous activities that increase intraocular pressure.
Choice B reason: Deep breathing and coughing four times a day are not related to cataract surgery. This is a technique to prevent respiratory complications after abdominal or thoracic surgery.
Choice C reason: After two days, a creamy discharge is not normal. This could indicate an infection or inflammation of the eye. The client should report any changes in vision, pain, redness, swelling, or discharge to the provider.
Choice D reason: Keeping the head up and straight is the correct instruction. This helps to prevent increased intraocular pressure and bleeding in the eye. The client should also avoid rubbing or touching the eye, wearing sunglasses to protect from bright light, and using prescribed eye drops as directed.
Correct Answer is A
Explanation
Choice A reason: This is the correct answer because this question will help the nurse assess the pain level and discomfort of the client with red scaling papules. Red scaling papules are raised skin lesions that are red and covered with scales. They can indicate psoriasis, which is a chronic skin condition that causes inflammation and rapid turnover of skin cells. Psoriasis can cause pain, itching, burning, or stinging sensations in the affected areas. The nurse should ask the client to rate their pain on a numeric or descriptive scale and provide analgesics or topical agents as prescribed.
Choice B reason: This is incorrect because this question will not help the nurse assess the condition of the client with red scaling papules. Red scaling papules are not affected by food intake but by other factors such as stress, infection, injury, or medication. Psoriasis is not an allergic or dietary disorder, but an immune-mediated disorder that causes abnormal skin cell growth. The nurse should ask the client about their medical history, current medications, and triggers or aggravating factors for their psoriasis.
Choice C reason: This is incorrect because this question will not help the nurse assess the condition of the client with red scaling papules. Red scaling papules are not treated with antibiotics but with other medications such as corticosteroids, immunosuppressants, or biologics. Antibiotics are used to treat bacterial infections, which are not the cause of psoriasis. The nurse should ask the client about their treatment regimen, compliance, and effectiveness for their psoriasis.
Choice D reason: This is incorrect because this question will not help the nurse assess the condition of
the client with red scaling papules. Red scaling papules are not related to weekend activities but to chronic skin inflammation and abnormal cell turnover. Psoriasis is not a lifestyle disorder, but a genetic disorder that can be influenced by environmental factors. The nurse should ask the client about their family history, exposure to sun or cold, and stress level for their psoriasis.
