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.

Answer and Explanation

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:

Phosphorus. Rationale: Dysfunction in the normal secretion of natriuretic hormones is more likely to affect sodium and water balance, not phosphorus. Phosphorus levels are regulated by other mechanisms in the body and may not be directly influenced by natriuretic hormones. Choice A is incorrect.

Choice B rationale:

Calcium. Rationale: Calcium levels are not typically influenced by natriuretic hormones. Calcium regulation is primarily under the control of parathyroid hormone (PTH) and calcitonin. Dysfunction in natriuretic hormone secretion would not directly impact calcium levels. Choice B is incorrect.

Choice C rationale:

Sodium. Rationale: Natriuretic hormones, such as atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP), play a crucial role in regulating sodium balance in the body. If a patient has dysfunction in the normal secretion of these hormones, it can lead to sodium imbalance, potentially causing sodium retention and fluid overload. Therefore, monitoring sodium levels is essential in such cases. Choice C is the correct answer.

Choice D rationale:

Aldosterone. Rationale: Aldosterone is a hormone that primarily regulates sodium and potassium balance in the body. Dysfunction in natriuretic hormone secretion is not directly related to aldosterone. Therefore, monitoring aldosterone levels would not be the most appropriate action in this context. Choice D is incorrect. .

A. A male with an enlarged upper chest. B. A female with abdominal obesity. C. A male with an active lifestyle. D. A female with menstrual problems.

Correct Answer is B

Explanation

Choice A rationale:

A male with an enlarged upper chest Enlarged upper chest in a male may suggest the development of pectoral muscles or chest-related muscular hypertrophy but is not a specific risk factor for coronary artery disease (CAD). The question is about CAD risk, and a male with an enlarged upper chest does not necessarily indicate a higher risk of CAD.

Choice B rationale:

A female with abdominal obesity Abdominal obesity, especially in females, is a significant risk factor for coronary artery disease (CAD). Excess fat around the abdomen can contribute to the development of atherosclerosis and increase the risk of CAD. This choice is correct because it highlights a well-established risk factor for CAD.

Choice C rationale:

A male with an active lifestyle Having an active lifestyle is generally associated with a reduced risk of CAD. Regular physical activity can help improve cardiovascular health, lower blood pressure, and reduce the risk of CAD. Therefore, a male with an active lifestyle is less likely to have a high risk of CAD.

Choice D rationale:

A female with menstrual problems Menstrual problems, while they can indicate hormonal imbalances or other health issues, are not directly linked to an increased risk of coronary artery disease. CAD risk factors typically revolve around lifestyle, genetics, and metabolic factors, which are not addressed by menstrual problems.
