A patient is in the ER for a suspected myocardial infarction.
The nurse sends a blood sample to the lab.
The patient asked the nurse what laboratory levels would be elevated to indicate an MI. The nurse replies:
Elevated potassium levels.
Elevated CK-MB and Troponin levels.
Elevated Lipid profile.
Elevated WBC count.
The Correct Answer is B
Choice A rationale:
Elevated potassium levels are not a specific indicator of a myocardial infarction (MI). They could be due to other conditions like kidney disease.
Choice B rationale:
Elevated CK-MB and Troponin levels are indeed indicators of an MI. These proteins are released into the blood when heart muscle is damaged.
Choice C rationale:
An elevated lipid profile is a risk factor for heart disease, but it does not indicate an acute MI.
Choice D rationale:
An elevated WBC count could indicate an infection or inflammation, but it is not a specific indicator of an MI.
