Which of the following describe a non-ST segment elevation myocardial infarction (NSTEMI)?

A.

A complete occlusion of the coronary artery

B.

Chest pain upon exertion that resolves with rest

C.

A partial occlusion of the coronary artery

D.

Chest pain while at rest

Answer and Explanation

The Correct Answer is C

A. A complete occlusion of the coronary artery is characteristic of an ST-segment elevation myocardial infarction (STEMI), not an NSTEMI.  
B. Chest pain that resolves with rest is more indicative of stable angina rather than NSTEMI.  
C. An NSTEMI occurs due to a partial occlusion of a coronary artery, leading to myocardial ischemia and damage without ST-segment elevation on an ECG.  
D. Chest pain at rest can be seen in both unstable angina and NSTEMI, but it is not the defining feature of NSTEMI.

Correct Answer is C

Explanation

A. A pulmonary function test is used to assess lung diseases like COPD or asthma. It is not the primary diagnostic test for fluid overload and heart failure.
B. Alpha-1 antitrypsin deficiency is associated with early-onset COPD, but it does not relate to symptoms of fluid retention and heart failure as described in the question.
C. Brain Natriuretic Peptide (BNP) is correct. BNP is released when the ventricles stretch due to fluid overload, making it a key diagnostic marker for heart failure. Elevated BNP levels indicate increased cardiac filling pressures and volume overload, which match the client’s symptoms.
D. A Doppler ultrasound is useful for detecting deep vein thrombosis (DVT) or vascular issues, but it does not assess systemic fluid retention and heart failure.
