If a patient develops an unstable plaque in the coronary arteries, which complication should the nurse monitor for in this patient?
Myocardial infarction.
Stable angina.
Eupnea.
Orthostatic hypotension.
The Correct Answer is A
Choice A rationale:
Unstable plaque in the coronary arteries is a major risk factor for myocardial infarction (MI), also known as a heart attack. When the plaque ruptures or becomes unstable, it can lead to the formation of a blood clot, which can obstruct the blood flow to the heart muscle, causing myocardial infarction. The nurse should monitor for signs and symptoms of MI in this patient, such as chest pain, shortness of breath, and ECG changes, to provide prompt intervention and prevent further cardiac damage.
Choice B rationale:
Stable angina is not the most immediate complication associated with unstable plaque in the coronary arteries. While stable angina is related to reduced blood flow to the heart, it is typically triggered by exertion or stress and relieved with rest or medication. Unstable plaque is more likely to lead to myocardial infarction, which is a more critical condition.
Choice C rationale:
Eupnea refers to normal, unlabored breathing and is not a complication associated with unstable plaque in the coronary arteries. It is essential to monitor the patient for cardiac-related complications, such as myocardial infarction, which can be life-threatening.
Choice D rationale:
Orthostatic hypotension, a drop in blood pressure upon standing, is not a typical complication of unstable plaque in the coronary arteries. The primary concern with unstable plaque is the risk of myocardial infarction, as it can lead to acute and severe cardiac damage.

Correct Answer is A
Explanation
Choice A rationale:
Mitogens like angiotensin II and growth factors stimulate smooth muscle proliferation. Mitogens are substances that promote cell division and growth. Angiotensin II, for example, is known to stimulate smooth muscle cell proliferation, which can lead to conditions like vascular remodeling and hypertension.
Choice B rationale:
Endothelial injury is not directly stimulated by mitogens. Mitogens are more associated with cell growth and proliferation rather than causing injury to endothelial cells.
Choice C rationale:
Mitogens are not typically associated with cardiac muscle toxicity. Cardiac muscle toxicity can result from various factors like certain medications or diseases, but mitogens are not the primary cause of cardiac muscle toxicity.
Choice D rationale:
Mitogens are not directly related to the activation of phagocytes. Phagocytes are white blood cells involved in the immune response, and their activation is more related to infection or inflammation rather than mitogenic stimulation. Moving on to the last question.
Correct Answer is C
Explanation
Choice A rationale:
Prinzmetal angina is not caused by blood clots in the coronary artery. It is primarily due to vasospasm of the coronary arteries.
Choice B rationale:
Prinzmetal angina is not caused by hypoxemia from respiratory disease. It is a vascular issue, not a respiratory one.
Choice C rationale:
Prinzmetal angina is caused by vasospasm of the coronary arteries. This constriction reduces blood flow to the heart muscle, leading to chest pain.
Choice D rationale:
Prinzmetal angina is not caused by deep vein thrombosis or hypotension. It is primarily related to vasospasm in the coronary arteries.
