Correct Answer: D

Rationale: The correct answer is D, dry mouth. Dry mouth is a common side effect of radiation therapy due to damage to the salivary glands. It is essential for the nurse to monitor for this condition as it can lead to oral health issues and discomfort. Fatigue (choice A) is a common side effect of radiation therapy, but in this case, dry mouth is a more specific side effect to monitor for. Hair loss (choice B) is more commonly associated with chemotherapy rather than radiation therapy. Nausea (choice C) is also a common side effect of radiation therapy, but dry mouth is a more direct effect of the treatment that the nurse should focus on monitoring.

Correct Answer: C

Rationale: The correct answer is C. Doxazosin can cause orthostatic hypotension, leading to dizziness and falls if the client rises quickly from a seated position. Instructing the client to rise slowly when sitting up from bed helps prevent these adverse effects. Choices A, B, and D are incorrect because doxazosin does not directly relate to caloric intake, dietary fiber, or a specific time of day for administration.

Correct Answer: B

Rationale: The correct answer is B: Broccoli. Broccoli is rich in calcium and is a suitable food to recommend to clients with osteoporosis to increase their calcium intake. Carrots, chicken, and bananas are not as high in calcium content compared to broccoli and therefore not the most appropriate choices for increasing calcium intake in clients with osteoporosis.

Correct Answer: C

Rationale: The correct answer is C because the client stating they should only take the inhaler when feeling short of breath indicates a need for further teaching. Clients with asthma should use their inhaler as prescribed, not just when short of breath. Choices A, B, and D demonstrate good asthma management practices. Choice A indicates understanding of using the albuterol inhaler before exercise to prevent exercise-induced symptoms. Choice B mentions the importance of not overusing the inhaler, which can indicate poor asthma control. Choice D shows awareness of rinsing the mouth after using a corticosteroid inhaler to prevent oral thrush.

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide, a loop diuretic, can lead to potassium loss in the urine, resulting in hypokalemia. This electrolyte imbalance is commonly seen in patients taking furosemide and requires close monitoring. Choices B, C, and D are incorrect because furosemide does not typically cause hyponatremia, hyperkalemia, or hypercalcemia as frequently as it causes hypokalemia.
