Correct Answer is A

Explanation

Choice A rationale:

Elevated troponin is a sign of heart damage, which could be caused by a heart attack or other stresses on the heart. This is a critical finding that needs immediate attention.

Choice B rationale:

Q waves on an ECG can indicate a previous heart attack or myocardial infarction. However, they can also be a normal variant, meaning they are a harmless variation in the electrical activity of the heart.

Choice C rationale:

Bilateral crackles in the lungs can indicate mucus or fluid in the base of the lungs, often associated with conditions like pneumonia, heart failure, or bronchitis.

Choice D rationale:

Hyperglycemia, or high blood glucose, can be a sign of diabetes. If untreated, it can lead to serious complications like ketoacidosis.

So, the correct answer is Choice A, after analyzing all choices.

A. Cardiac-specific troponin. B. Myoglobin. C. Homocysteine. D. C-reactive protein.

Correct Answer is A

Explanation

Choice A rationale:

Cardiac-specific troponin is a protein that is released into the bloodstream when there is damage to the heart muscle, such as during an acute myocardial infarction (AMI). It is considered the most specific marker for AMI because it is found only in heart muscle. The normal range for troponin I is between 0 and 0.04 ng/mL2.

Choice B rationale:

Myoglobin is a protein found in heart and skeletal muscles. While it can be elevated in AMI, it is not as specific as troponin because it is also found in skeletal muscles. The normal levels of myoglobin are 25 to 72 ng/mL4.

Choice C rationale:

Homocysteine is an amino acid in the blood, and high levels can increase the risk of heart disease. However, it is not specific for AMI5. The normal range of homocysteine levels are less than 15 micromoles per liter.

Choice D rationale:

C-reactive protein (CRP) is a marker of inflammation in the body and can be elevated in various conditions, including heart disease. However, it is not specific for AMI6. The normal CRP level is less than 0.9 milligrams per deciliter.

So, the correct answer is A, after analyzing all choices.
