MMSC436 Practice Cardiac Assessment
Exam Questions & Answers (Grade A+)
Which one of the following cardiac biomarkers is elevated about 50
times the upper limit of normal at 24 hours after onset of an acute
myocardial infarction?
Total CK
Troponin
Myoglobin
CK-2 (CKMB) -
correct answer ✅Troponin
Why would high-sensitivity C-reactive protein (CRP) be an indicator
of a potential myocardial infarction?
CRP levels rise in response to decreased ATP generation in the
heart.
It is a myocardial protein that regulates muscle contraction through
interaction with myosin and actin.

Exam Questions & Answers (Grade A+)
Myoglobin is a good cardiac marker because it:
Is an extremely large protein and therefore does not diffuse into
the blood very easily.
Diffuses into the blood more slowly than CK-MB.
Doesn't diffuse into the blood at all when cardiac tissue dies.
Diffuses into the blood more quickly than CK-MB. -
correct answer ✅Diffuses into the blood more quickly than CK-MB.

Troponin M and troponin H
Troponin A, troponin C, and troponin T
Troponin T, troponin I, and troponin C
