Which of the following describe a non-ST segment elevation myocardial infarction (NSTEMI)?
A complete occlusion of the coronary artery
Chest pain upon exertion that resolves with rest
A partial occlusion of the coronary artery
Chest pain while at rest
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 D
Explanation
A. Use of accessory muscles during inspiration is common in COPD as clients work harder to breathe. While this indicates respiratory distress, it is not necessarily an immediate emergency.
B. Large amounts of thick white sputum can indicate mucus production, which is common in COPD. If the sputum were yellow or green, it could suggest infection, requiring further assessment.
C. A barrel chest and clubbing are chronic changes in COPD due to prolonged air trapping and hypoxia. These findings do not require immediate intervention.
D. Oxygen flowmeter set on 8 LPM is correct. High-flow oxygen can suppress the hypoxic drive in COPD clients, leading to respiratory depression. The nurse should immediately lower the oxygen to a safer level (typically 1-3 LPM) and monitor the client’s respiratory status.
Correct Answer is B
Explanation
A. Weight gain is more commonly associated with right-sided heart failure due to fluid retention and peripheral edema, not left-sided heart failure.
B. Shortness of breath (dyspnea) is correct. Left-sided heart failure causes pulmonary congestion, leading to dyspnea, orthopnea, and pulmonary edema as blood backs up into the lungs.
C. Pulmonary embolism is not a direct manifestation of left-sided heart failure. While heart failure increases the risk of clot formation, a pulmonary embolism is a separate condition.
D. Anorexia is more common in right-sided heart failure, as systemic venous congestion can lead to gastrointestinal edema and poor appetite.
