Correct Answer: A

Rationale: Corrected Rationale: Hydrochlorothiazide is a diuretic known to cause electrolyte imbalances, particularly hyponatremia (low sodium levels). The nurse should closely monitor the client for signs of hyponatremia by assessing their electrolyte levels. Choice B, Hyperkalemia, is incorrect as hydrochlorothiazide is more likely to cause hypokalemia (low potassium levels) rather than hyperkalemia. Choice C, Hypercalcemia, is incorrect because hydrochlorothiazide is not known to cause increased calcium levels. Choice D, Hypoglycemia, is also incorrect as it is not a common adverse effect of hydrochlorothiazide.

Correct Answer: A

Rationale: Phenobarbital has a long half-life of 4 days, meaning it remains at therapeutic levels in the body for an extended period. Due to this prolonged duration of action, the nurse should expect to administer phenobarbital once a day to maintain therapeutic levels and effectiveness. Administering it more than once a day would lead to unnecessary dosing and potential adverse effects as the medication remains active in the body for an extended period.

Correct Answer: A

Rationale: The correct answer is A: 'I am frequently constipated.' Constipation is a common adverse effect of Verapamil, a calcium channel blocker. Verapamil can slow down intestinal motility, leading to constipation as a side effect. Choices B, C, and D are not typically associated with adverse effects of Verapamil. Increased urination is not a common side effect, skin peeling is not related to Verapamil use, and ringing in the ears is not a typical adverse effect of this medication.

Correct Answer: A

Rationale: The correct answer is A: Edema. The nurse should monitor the client for edema when receiving imatinib. Imatinib, a tyrosine kinase inhibitor, can lead to fluid retention and edema as a common adverse effect. This can manifest as swelling in various parts of the body, indicating the need for close monitoring by the nurse to prevent complications related to fluid overload. Choices B, C, and D are incorrect because constipation, dry mouth, and urinary retention are not typically associated with imatinib use. Therefore, they are not the priority adverse effects to monitor in a client receiving this medication.

Correct Answer: D

Rationale: The correct answer is D: 'Monitor for leg cramps.' Leg cramps may indicate hypokalemia, an adverse effect of hydrochlorothiazide, and should be reported to the provider. Choice A is incorrect because hydrochlorothiazide is usually taken in the morning to avoid nocturia. Choice B is incorrect as hydrochlorothiazide is a diuretic that helps lower blood pressure. Choice C is incorrect as hydrochlorothiazide can be taken with or without food.
