Correct Answer: A

Rationale: The correct answer is Lisinopril. Lisinopril is an ACE inhibitor commonly prescribed to patients with hypertension to manage their blood pressure. Metformin is used to treat type 2 diabetes, not hypertension (choice B). Atorvastatin is a statin used to lower cholesterol levels, not primarily prescribed for hypertension (choice C). Aspirin is used for its antiplatelet effects and in preventing cardiovascular events, but it is not a first-line treatment for hypertension (choice D). Therefore, Lisinopril is the most suitable choice for a patient with hypertension.

Correct Answer: A

Rationale: Corrected Rationale: Potassium levels should be monitored closely in a patient receiving digoxin to avoid hypokalemia. Digoxin can increase the risk of developing life-threatening arrhythmias in the presence of low potassium levels. Monitoring sodium, calcium, or glucose levels is not specifically necessary for patients on digoxin, making choices B, C, and D incorrect.

Correct Answer: D

Rationale: The correct answer is D, Metformin. Metformin should be discontinued 48 hours before an arteriogram due to the risk of lactic acidosis. Atorvastatin (Choice A) is a statin used to lower cholesterol levels and is not typically contraindicated before an arteriogram. Digoxin (Choice B) is a medication used for heart conditions and does not need to be discontinued before an arteriogram. Nifedipine (Choice C) is a calcium channel blocker used to treat high blood pressure and angina, and it is not necessary to discontinue before the procedure.

Correct Answer: B

Rationale: The correct answer is B. Clients should eat a snack when their blood glucose level is low, typically below 70-100 mg/dL, not when it is high. Eating a snack when the blood glucose level is above 200 mg/dL can exacerbate hyperglycemia. Choice A is correct as checking blood glucose levels regularly is important in managing diabetes. Choice C is also correct as adherence to prescribed insulin therapy is crucial. Choice D is incorrect as physical activity can help lower blood glucose levels, especially when they are above the target range.

Correct Answer: C

Rationale: The correct intervention for a client with DVT is to apply cold packs to the affected extremity. Cold packs can help reduce swelling and pain by constricting blood vessels. Massaging the affected extremity can dislodge a clot and worsen the condition. Elevating the affected extremity helps with blood flow but is not the priority intervention for DVT. Performing range-of-motion exercises on the affected extremity can also dislodge a clot and is contraindicated.
