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

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.

Explanation

Obtain intravenous (IV) access: IV access is necessary for administering medications, fluids, and emergency interventions.
Obtain the client's family history: While family history is important for long-term cardiac risk assessment, it is not a priority in the acute phase of chest pain management.
Apply continuous ECG monitoring: Continuous ECG monitoring is critical for detecting arrhythmias, ischemic changes, and potential myocardial infarction (MI).
Administer O₂ to maintain oxygen saturation greater than 90%: Oxygen therapy is indicated in clients with suspected MI if their oxygen saturation is below 90% to prevent further myocardial ischemia.

A. Notify the provider of a weight gain of 0.5 kg (1 lb) in a week. B. Take naproxen for generalized discomfort. C. Exercise at least three times per week. D. Take diuretics early in the morning and before bedtime.

Correct Answer is C

Explanation

A. The client should notify the provider of a weight gain of 2-3 lbs in a day or 5 lbs in a week, as this may indicate fluid retention and worsening heart failure.
B. Naproxen (NSAIDs) should be avoided as they can lead to sodium retention, fluid overload, and worsening heart failure.
C. Exercising at least three times per week is correct. Regular physical activity can help improve cardiovascular function and overall endurance, provided it is within safe limits.
D. Diuretics should be taken in the morning, but not before bedtime. Taking them late can lead to nocturia and sleep disturbances.
