A client with suspected angina pectoris is scheduled for a coronary angiography. The client asks the nurse about the purpose of the test. How should the nurse respond?

"Coronary angiography will measure the levels of cardiac biomarkers in your blood."

"It is a stress test that evaluates your heart's response to increased demand."

"The test involves injecting dye into your coronary arteries to visualize any blockages."

"Coronary angiography will assess your heart's function using sound waves."

Answer and Explanation

The Correct Answer is C

A) This choice is incorrect because measuring the levels of cardiac biomarkers in the blood is not the purpose of coronary angiography. Cardiac biomarkers are measured through blood tests to diagnose conditions like myocardial infarction (MI).

B) This choice is incorrect because a stress test evaluates the heart's response to increased demand and is different from coronary angiography.

C) This choice is correct. Coronary angiography is an invasive procedure that involves injecting a contrast dye into the coronary arteries. The dye allows visualization of the coronary arteries and identifies any blockages or narrowing that may be causing angina or other cardiac symptoms.

D) This choice is incorrect because assessing the heart's function using sound waves is characteristic of an echocardiogram, not coronary angiography.

Correct Answer is D

Explanation

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.

A. Myoglobin. B. C-reactive protein (CRP). C. Brain natriuretic peptide (BNP). D. Troponin.

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.
