A patient reports episodic chest pain lasting a few minutes that is provoked by exertion and relieved within 10 minutes upon resting.
Which cause of the patient's symptoms would the nurse suspect?

Spasm of a major coronary artery.

Exposure of the thrombogenic surface to plaque.

Myocardial ischemia due to coronary artery disease.

Myocardial ischemia secondary to microvascular disease.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

Spasm of a major coronary artery, also known as variant (Prinzmetal's) angina, typically occurs at rest and is not necessarily provoked by exertion. The patient's chest pain is exacerbated by exertion, making this choice less likely.

Choice B rationale:

Exposure of the thrombogenic surface to plaque refers to acute coronary syndromes like unstable angina or myocardial infarction. While plaque rupture and thrombosis can cause myocardial ischemia, the characteristic feature of these conditions is chest pain that may not be relieved by rest, unlike the patient described here.

Choice D rationale:

Myocardial ischemia secondary to microvascular disease, also known as cardiac syndrome X, is a condition where chest pain occurs without significant coronary artery stenosis. However, this condition usually affects women, and the pain is often unrelated to exertion. In the given case, the pain is provoked by exertion, making this choice less likely.

Correct Answer is C

Explanation

Choice A rationale:

Metabolic acidosis is characterized by low blood pH and low bicarbonate ion levels. The patient's bicarbonate ion level (24 mEq/L) is within the normal range, and the low pH (7.32) and elevated PaCO2 (56 mm Hg) indicate respiratory acidosis, not metabolic acidosis.

Choice B rationale:

Metabolic alkalosis is characterized by high blood pH and high bicarbonate ion levels. The patient's pH is low (7.32), and the bicarbonate ion level (24 mEq/L) is within the normal range, indicating respiratory acidosis rather than metabolic alkalosis.

Choice C rationale:

Respiratory acidosis is characterized by low blood pH and high PaCO2 levels. In this case, the patient has a low pH (7.32) and elevated PaCO2 (56 mm Hg), indicating respiratory acidosis. The bicarbonate ion level (24 mEq/L) is a compensatory response. Respiratory alkalosis would present with high pH and low PaCO2 levels.

Choice D rationale:

Respiratory alkalosis is characterized by high blood pH and low PaCO2 levels. The patient's PaCO2 level is elevated (56 mm Hg), indicating respiratory acidosis, not alkalosis. The low pH (7.32) further supports the diagnosis of respiratory acidosis.

A. "The treatment has severe side effects, some of which will be permanent.” B. "You need to use your call light to ask for help every time you get out of bed.” C. "Prevention and early detection of infection are important during leukemia treatment.” D. "Feeling isolated is a common and unavoidable consequence of leukemia treatment.”

Correct Answer is C

Explanation

Choice A rationale:

While leukemia treatment does have severe side effects, not all of them are permanent. It is essential for the patient to be aware of potential complications but also to understand that some side effects might be temporary and can be managed with appropriate care.

Choice B rationale:

Using the call light to ask for help when getting out of bed is essential for patients receiving chemotherapy, as their immune system might be compromised, making them prone to infections and injuries. However, this information is not specific to leukemia treatment but is a general safety measure for these patients.

Choice C rationale:

Patients undergoing chemotherapy for leukemia are at an increased risk of infections due to the suppression of the immune system. Preventive measures, such as good hygiene practices and early detection of signs of infection, are crucial in managing these patients. Educating the patient about infection prevention is essential for their safety during treatment.

Choice D rationale:

Feeling isolated can be a common emotional response to any chronic illness, including leukemia. However, it is not an unavoidable consequence, and providing emotional support and involving the patient in support groups can help mitigate these feelings. This statement does not provide essential information about managing leukemia treatment.
