Correct Answer: B

Rationale: The correct teaching for a client prescribed hydrochlorothiazide is to increase fluid intake to prevent dehydration. Hydrochlorothiazide is a diuretic that can lead to fluid loss and electrolyte imbalances, so adequate fluid intake is crucial. Choice A is incorrect because hydrochlorothiazide is typically taken in the morning to avoid nighttime urination. Choice C is incorrect as potassium-rich foods should not be avoided but monitored, as hydrochlorothiazide can cause potassium loss. Choice D is incorrect as potassium levels should be monitored regularly, but not necessarily weekly, unless indicated by the healthcare provider.

Correct Answer: A

Rationale: Administering a bronchodilator is the priority intervention to open the airways and relieve wheezing and shortness of breath. Bronchodilators work quickly to dilate the airways, making it easier for the client to breathe. Checking oxygen saturation is important but can be done after initiating bronchodilator therapy. Encouraging pursed-lip breathing and elevating the head of the bed can help improve breathing patterns but should follow the administration of the bronchodilator.

Correct Answer: B

Rationale: The correct answer is B because gabapentin is prescribed to treat phantom limb pain, which is common in individuals with amputations. Option A is not the most important intervention at this time since the client is reporting physical pain, not emotional distress. Option C is not appropriate because the client is reporting aching in the foot, not the stump. Option D does not address the underlying issue of phantom limb pain that needs to be managed.

Correct Answer: B

Rationale: The correct recommendation for a client with dry, peeling skin at a radiation therapy treatment site is to use mild soap and water to cleanse the area. This approach helps in preventing skin irritation and reduces the risk of infection. Applying lotion (Choice A) may further irritate the skin due to the chemicals present in the lotion. Covering the area with a sterile dressing (Choice C) is not necessary unless there is an open wound that needs protection. Allowing the skin to air dry after washing (Choice D) may lead to further dryness and peeling.

Correct Answer: D

Rationale: The correct answer is D: 'Use sunscreen to prevent photosensitivity.' Methotrexate increases photosensitivity, so clients should be advised to use sunscreen to protect their skin from sun exposure. Choice A is incorrect because methotrexate is usually taken with food to reduce gastrointestinal side effects. Choice B may be important but is not specific to methotrexate therapy. Choice C is also important, but the primary reason for folic acid supplementation with methotrexate is to reduce the risk of certain side effects like anemia rather than preventing anemia itself.
