A nurse is administering aspirin to a client who has angina and is at risk for myocardial infarction. Which of the following statements by the nurse explains the rationale for this medication?
“Aspirin will help lower your blood pressure and reduce your cardiac workload.”
“Aspirin will help prevent blood clots from forming in your coronary arteries.”
“Aspirin will help dilate your coronary arteries and increase blood flow to your heart.”
“Aspirin will help reduce inflammation and pain in your chest.”.
The Correct Answer is B
Aspirin is an antiplatelet drug that inhibits the aggregation of platelets and prevents the formation of thrombi, which can occlude the coronary arteries and cause angina or myocardial infarction. Aspirin is recommended for clients who have angina and are at risk for myocardial infarction as a secondary prevention measure.
Choice A is wrong because aspirin does not lower blood pressure or reduce cardiac workload. These effects are achieved by other drugs such as beta blockers, calcium channel blockers, or angiotensin-converting enzyme inhibitors.
Choice C is wrong because aspirin does not dilate the coronary arteries or increase blood flow to the heart. These effects are achieved by other drugs such as nitrates or calcium channel blockers.
Choice D is wrong because aspirin does not reduce inflammation or pain in the chest. These effects are achieved by other drugs such as nonsteroidal anti-inflammatory drugs or opioids.

Correct Answer is A
Explanation
Nitroprusside is a vasodilator that lowers blood pressure by dilating blood vessels.It is used to treat hypertensive crisis, which is a life-threatening condition of very high blood pressure.However, nitroprusside can cause excessive hypotension, which is a serious side effect that can lead to irreversible ischemic injuries or death. Therefore, the nurse should monitor the client’s blood pressure continuously and adjust the infusion rate accordingly.
Choice B is wrong because Bradycardia is wrong because nitroprusside does not affect the heart rate directly.However, bradycardia can occur as a reflex response to hypotension, which is a possible adverse effect of nitroprusside. Therefore, the nurse should also monitor the client’s heart rate and rhythm.
Choice C is wrong because Tachycardia is wrong because nitroprusside does not cause tachycardia directly.However, tachycardia can occur as a compensatory mechanism to hypotension, which is a possible adverse effect of nitroprusside. Therefore, the nurse should also monitor the client’s heart rate and rhythm.
Choice D is wrong because Hypertension is wrong because nitroprusside is used to lower blood pressure, not to raise it.However, hypertension can occur if the infusion is stopped abruptly, which can cause rebound vasoconstriction and increased blood pressure. Therefore, the nurse should taper off the infusion gradually and avoid sudden discontinuation.
Normal ranges for blood pressure are systolic less than 120 mmHg and diastolic less than 80 mmHg.
Normal ranges for heart rate are 60 to 100 beats per minute.
