A patient has a myocardial infarction.
Which one of the following changes will occur in the patient's myocardial cells surrounding the infarct?
Temporary increase in contractile activity.
Increased metabolism.
Myocardial remodeling.
Necrosis.
The Correct Answer is C
Choice A rationale:
A temporary increase in contractile activity would not typically occur in the myocardial cells surrounding a myocardial infarction. During a myocardial infarction, the affected area of the heart experiences a lack of blood supply, leading to cell damage. The damaged cells cannot increase contractile activity; instead, they may become dysfunctional or die.
Choice B rationale:
An increased metabolism is not a characteristic change in myocardial cells surrounding a myocardial infarction. The infarcted area often experiences reduced metabolism due to reduced blood flow and oxygen supply, leading to cellular damage and dysfunction.
Choice D rationale:
Necrosis is a common outcome in myocardial cells surrounding an infarct. However, this is not the immediate change that occurs but rather the eventual result of ischemic injury. During an acute myocardial infarction, cellular changes such as inflammation and eventual necrosis take place, leading to tissue damage. Now, let's move on to the next question:

Correct Answer is C
Explanation
Choice A rationale:
Hypertension is not the term used to describe insufficient coronary blood flow. Hypertension refers to high blood pressure, which may contribute to cardiovascular issues, but it does not directly describe the inadequate blood flow.
Choice B rationale:
Metabolic syndrome is also unrelated to insufficient coronary blood flow. Metabolic syndrome is a cluster of conditions that increase the risk of heart disease, stroke, and type 2 diabetes. It doesn't describe the process of inadequate blood flow.
Choice C rationale:
Myocardial ischemia is the correct term to describe insufficient coronary blood flow. Ischemia occurs when there is an inadequate supply of blood to the heart muscle, leading to oxygen deprivation. This term accurately characterizes the condition mentioned in the question.
Choice D rationale:
Diuresis is unrelated to the process of insufficient coronary blood flow. Diuresis refers to increased urine production and does not address the primary issue, which is inadequate blood supply to the heart.
Correct Answer is C
Explanation
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.
