A nurse caring for a patient with unstable angina will most likely need to give medications to accomplish which desirable objective?

Decrease coronary artery constriction by giving aspirin.

Increase afterload for the left ventricle in order to maximize cardiac output.

Increase preload to reduce overall cardiac workload.

Reduce arterial inflammation by administering statins.

Answer and Explanation

The Correct Answer is A

Choice A rationale
Decreasing coronary artery constriction by giving aspirin is a primary objective in managing unstable angina. Aspirin inhibits platelet aggregation, reducing the risk of clot formation and improving blood flow in the coronary arteries. This helps to alleviate chest pain and prevent myocardial infarction.
Choice B rationale
Increasing afterload for the left ventricle to maximize cardiac output is not a desirable objective in managing unstable angina. Increasing afterload would increase the workload on the heart, which is counterproductive in patients with angina. The goal is to reduce the heart’s workload and improve blood flow.
Choice C rationale
Increasing preload to reduce overall cardiac workload is not a primary objective in managing unstable angina. Increasing preload would increase the volume of blood returning to the heart, potentially worsening symptoms. The focus is on reducing myocardial oxygen demand and improving coronary perfusion.
Choice D rationale
Reducing arterial inflammation by administering statins is a long-term strategy for managing cardiovascular disease, but it is not the immediate objective in managing unstable angina.
Statins help to lower cholesterol levels and reduce inflammation, but the immediate goal in unstable angina is to relieve chest pain and prevent myocardial infarction.

Correct Answer is A

Explanation

Choice A rationale
Serum amylase is typically elevated in acute pancreatitis. It is one of the key diagnostic markers for this condition.
Choice B rationale
Serum potassium levels are not typically elevated in acute pancreatitis. Potassium levels are more commonly associated with kidney function and electrolyte balance.
Choice C rationale
Serum calcium levels are usually decreased, not elevated, in acute pancreatitis. Hypocalcemia can occur due to fat saponification in the pancreas.
Choice D rationale
Serum sodium levels are not typically elevated in acute pancreatitis. Sodium levels are more related to overall fluid balance and kidney function.

A. Blood pressure of 180/120 mmHg. B. Heart rate of 90 beats per minute. C. Respiratory rate of 20 breaths per minute. D. Temperature of 37°C (98.6°F).

Correct Answer is A

Explanation

Choice A rationale
A blood pressure reading of 180/120 mmHg or higher is indicative of a hypertensive crisis. This condition requires immediate medical attention to prevent damage to vital organs such as the heart, kidneys, and brain.
Choice B rationale
A heart rate of 90 beats per minute is within the normal range and does not indicate a hypertensive crisis. While it is important to monitor heart rate, it is not a definitive sign of a hypertensive emergency.
Choice C rationale
A respiratory rate of 20 breaths per minute is within the normal range and does not indicate a hypertensive crisis. Respiratory rate alone is not a reliable indicator of hypertensive emergencies.
Choice D rationale
A temperature of 37°C (98.6°F) is normal and does not indicate a hypertensive crisis. Body temperature is not a primary indicator of hypertensive emergencies.
