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
Acute pancreatitis is characterized by severe epigastric pain and elevated levels of amylase and lipase. These enzymes are released into the bloodstream when the pancreas is inflamed, making acute pancreatitis the most likely diagnosis.
Choice B rationale
Acute hematochezia refers to the passage of fresh blood through the anus, usually in or with stools. It is not associated with elevated amylase and lipase levels or severe epigastric pain.
Choice C rationale
Left heart failure can cause symptoms such as shortness of breath and fluid retention, but it does not typically cause elevated amylase and lipase levels or severe epigastric pain.
Choice D rationale
Chronic hepatic failure involves long-term liver damage and may present with jaundice, ascites, and other symptoms. It is not associated with elevated amylase and lipase levels or severe epigastric pain.

A. The hypokalemia brought on severe muscle spasms, causing exhaustion. B. Due to his low potassium, his cells rely on glycolysis. C. Due to the hypokalemia, his cells are hyperpolarized. D. The hypernatremia caused cellular dehydration, leading to lethargy.

Correct Answer is D

Explanation

Choice A rationale
Hypokalemia can cause muscle weakness and cramps, but it does not typically lead to severe muscle spasms causing exhaustion. The patient’s symptoms of lethargy and weakness are more likely related to electrolyte imbalances and dehydration rather than muscle spasms.
Choice B rationale
While low potassium levels can affect cellular metabolism, the primary issue here is not glycolysis. The patient’s symptoms are more consistent with dehydration and electrolyte imbalances rather than a metabolic shift to glycolysis.
Choice C rationale
Hypokalemia can cause cells to become hyperpolarized, leading to muscle weakness and decreased reflexes. However, the patient’s symptoms of lethargy and weakness are more likely due to dehydration and electrolyte imbalances rather than cellular hyperpolarization.
Choice D rationale
Hypernatremia, or high sodium levels, can cause cellular dehydration, leading to symptoms such as lethargy and weakness. The patient’s lab results and clinical presentation are consistent with hypernatremia-induced cellular dehydration, which explains his symptoms.
