A client is scheduled for patch testing to determine allergies to several substances. Which nursing activities associated with this test are best delegated to a medical assistant working in the allergy clinic?

Correct Answer: C

Rationale: The correct answer is C because scheduling a client for a follow-up appointment is an administrative task that can be delegated to a medical assistant. This task does not require specialized nursing knowledge or assessment skills. Explanation of why the other choices are incorrect: A: Explaining the purpose of the testing to the client requires nursing knowledge and understanding of the procedure, so it should be performed by a nurse. B: Examining the patch area for evidence of a reaction involves assessment skills that only a nurse should perform to accurately identify and interpret potential reactions. D: Monitoring for anaphylactic reactions after administration of the test is a critical nursing responsibility that requires immediate intervention if a reaction occurs. This task should not be delegated to a medical assistant.

Correct Answer: D

Rationale: The correct answer is D: Pediculicides. Pediculicides are drugs used specifically to treat lice infestations. They work by killing lice and their eggs. In this scenario, the client is prescribed drug therapy for lice treatment, making pediculicides the appropriate drug class. Antihistamines (choice A) are used to relieve allergy symptoms, antifungals (choice B) treat fungal infections, and keratolytics (choice C) help remove dead skin cells. These choices are incorrect as they do not target lice infestations.

Correct Answer: C

Rationale: The correct answer is C: Avoid walking barefoot. This practice helps prevent spreading the fungal infection to other areas and reduces the risk of reinfection. Walking barefoot in public places can expose the affected foot to more fungi. Explanation: 1. Walking barefoot increases the risk of spreading the infection. 2. Shoes act as a barrier to protect the affected foot. 3. Avoiding barefoot walking reduces the chances of reinfection. 4. It is a key preventive measure in managing onychomycosis. Summary: A: Incorrect. Antifungal medications for onychomycosis need to be taken for several weeks to months, not just 5 to 10 days. B: Incorrect. Changing footwear alone does not target the root cause of the infection. D: Incorrect. Keeping the feet moist can exacerbate the fungal growth.

Correct Answer: C

Rationale: The correct answer is C because during burn injury recovery, protein needs increase significantly to promote tissue repair and wound healing, which is typically two to four times higher than normal. Higher calorie intake is also required to support the increased metabolic demands of healing. Option A is incorrect as it underestimates protein needs. Option B is incorrect as it suggests inadequate protein intake. Option D is incorrect as it recommends insufficient calories for the increased protein needs.

Correct Answer: D

Rationale: The correct answer is D because topical hydrocortisone does not block photosensitivity caused by drugs. Topical hydrocortisone is a corticosteroid used to reduce inflammation in the skin, not to block photosensitivity. A is incorrect because obesity can actually lead to decreased sweating, not increased sweating. B is incorrect because benzophenones primarily protect against UVB rays, not both UVA and UVB. C is incorrect because while UVA rays do contribute to skin cancer, UVB rays are considered the primary cause.
