A nurse is asked what causes Prinzmetal angina.
How should the nurse respond? Prinzmetal angina is caused by:.

Choice A rationale:

Calcium is not the recommended nutrient for a patient with hyperhomocysteinemia. Hyperhomocysteinemia is characterized by elevated levels of homocysteine in the blood, and it is often associated with a deficiency of folate, vitamin B6, and vitamin B12. Folate is crucial in the metabolism of homocysteine and helps reduce its levels in the blood.

Choice B rationale:

Potassium is not a specific nutrient indicated for hyperhomocysteinemia. Potassium is primarily associated with maintaining electrolyte balance and is not directly linked to the management of homocysteine levels.

Choice D rationale:

Protein is not the recommended nutrient for a patient with hyperhomocysteinemia. While protein is essential for various bodily functions, it is not specifically targeted to address the issue of elevated homocysteine levels.

Choice A rationale:

Pericardial rub A pericardial rub is a clinical finding where a healthcare provider can hear a grating or scratching sound when listening to the heart using a stethoscope. It is a sign of inflammation of the pericardium (pericarditis) but is not necessarily associated with the rapid collection of fluid in the pericardial sac. Pericardial rub is more indicative of inflammation and not fluid accumulation.

Choice B rationale:

Pericardial effusion Pericardial effusion is the abnormal accumulation of fluid in the pericardial sac surrounding the heart. If the fluid accumulates rapidly, it can lead to cardiac tamponade, a life-threatening condition where the heart's ability to pump blood is compromised. The nurse should observe for signs and symptoms of pericardial effusion and its complications in the patient's chart when rapid fluid collection is suspected.

Choice C rationale:

Cardiomyopathy Cardiomyopathy is a condition characterized by abnormal heart muscle function. It can lead to heart failure and other cardiac issues, but it is not directly related to the rapid collection of fluid in the pericardial sac. The question specifically focuses on a condition resulting from the rapid accumulation of fluid in the pericardial sac.

Choice D rationale:

Constrictive pericarditis Constrictive pericarditis is a condition in which the pericardium becomes thickened and rigid, restricting the heart's ability to expand and fill with blood. It is a chronic condition and not typically associated with a rapid collection of fluid in the pericardial sac. Rapid fluid accumulation leading to tamponade is more indicative of pericardial effusion, which is the correct answer.
