Rationale: Nitroglycerin is the medication typically prescribed to prevent angina attacks. It works by dilating blood vessels, increasing blood flow, and reducing the heart's workload, hence relieving angina symptoms. Aspirin is often used to prevent blood clots, Atenolol is a beta-blocker used to manage high blood pressure and chest pain, and Simvastatin is a statin medication primarily used to lower cholesterol levels.

Correct Answer: A

Rationale: Elevating the affected leg using pillows is essential in managing deep vein thrombosis (DVT) as it helps reduce swelling and promote venous return, thus decreasing the risk of complications such as pulmonary embolism. This position aids in improving blood circulation and preventing blood clots from forming or worsening in the affected leg.

Correct Answer: B

Rationale: The correct answer is serum potassium. Monitoring serum potassium levels is crucial when a client is receiving digoxin (Lanoxin) because low potassium levels can increase the risk of digoxin toxicity. Digoxin and low potassium levels can lead to serious cardiac complications, such as arrhythmias. Therefore, close monitoring of serum potassium is essential to prevent adverse effects and ensure the safe administration of digoxin in clients with heart failure.

Correct Answer: B

Rationale: It is essential to rotate the application site of the nitroglycerin patch to prevent skin irritation and ensure consistent absorption of the medication. Applying it to the same site can lead to skin irritation and decreased effectiveness.

Correct Answer: B

Rationale: Thrombolytic therapy is associated with an increased risk of bleeding due to its mechanism of action in dissolving blood clots. Therefore, the nurse should closely monitor the client for any signs of hemorrhage, such as unexplained bruising, bleeding gums, or blood in the urine or stools.
