A client with angina pectoris is receiving sublingual nitroglycerin for chest pain relief. After administering the medication, what should the nurse instruct the client to do?

Lie down in bed and rest for at least 30 minutes.

Monitor blood pressure and heart rate every 15 minutes.

Avoid drinking water or any fluids for an hour.

Sit or lie down and avoid sudden position changes.

Answer and Explanation

The Correct Answer is D

A) This choice is incorrect because while rest is essential during an angina episode, lying down in bed for an extended period is not necessary after administering nitroglycerin.

B) This choice is incorrect because monitoring blood pressure and heart rate every 15 minutes is not a standard nursing intervention after nitroglycerin administration. Monitoring vital signs as needed for the client's condition is appropriate.

C) This choice is incorrect because there is no need for the client to avoid drinking water or fluids after taking sublingual nitroglycerin.

D) This choice is correct. After taking sublingual nitroglycerin for chest pain relief, the client should sit or lie down and avoid sudden position changes. Nitroglycerin can cause systemic vasodilation and may lead to orthostatic hypotension, increasing the risk of dizziness or falls if the client stands up abruptly. Taking a seated or lying position reduces this risk and allows the medication to work effectively to relieve chest pain.

Correct Answer is D

Explanation

A) This choice is incorrect because myoglobin is a cardiac biomarker that may be elevated in MI, but it lacks specificity and can also be elevated in other conditions like skeletal muscle injury.

B) This choice is incorrect because C-reactive protein (CRP) is an inflammatory marker and is not specific to MI. It may be elevated in various inflammatory conditions.

C) This choice is incorrect because brain natriuretic peptide (BNP) is a biomarker associated with heart failure and is not specific to diagnosing MI.

D) This choice is correct. Troponin is the most specific biomarker for diagnosing MI. Elevated troponin levels in the blood indicate cardiac muscle damage, making it a reliable marker for myocardial infarction. Troponin levels rise shortly after the onset of MI and remain elevated for several days, making it valuable in both early and delayed MI detection.

A. "Beta-blockers help dilate your blood vessels, improving blood flow to your heart." B. "It reduces your cholesterol levels and prevents the formation of plaques in your arteries." C. "Beta-blockers lower your blood pressure and decrease the workload of your heart." D. "It prevents blood clots from forming in your coronary arteries and causing another MI."

Correct Answer is C

Explanation

A) This choice is incorrect because beta-blockers do not directly dilate blood vessels. They primarily work by blocking the effects of adrenaline on the heart and blood vessels, leading to decreased heart rate and reduced blood pressure.

B) This choice is incorrect because beta-blockers do not directly affect cholesterol levels or prevent the formation of plaques in arteries. Their primary action is on the cardiovascular system, particularly the heart and blood pressure.

C) This choice is correct. Beta-blockers are commonly prescribed after an MI to reduce the workload of the heart and lower blood pressure. By blocking the effects of adrenaline, they help slow down the heart rate and reduce the force of contraction, thereby decreasing myocardial oxygen demand and improving the heart's efficiency.

D) This choice is incorrect because beta-blockers do not directly prevent blood clot formation in coronary arteries. Anticoagulant or antiplatelet medications are used to reduce the risk of clot formation in individuals at high risk for recurrent heart attacks.
