Review Lewis's Medical Surgical Nursing in Canada, 5th Edition - Nursing Management: Coronary Artery Disease and Acute Coronary Syndrome related questions and content

The nurse is caring for a patient who has had severe chest pain for several hours and a diagnosis of possible acute myocardial infarction. Which of the following prescribed laboratory tests should the nurse monitor to help determine the diagnosis?

  • A. Homocysteine
  • B. C-reactive protein
  • C. Cardiac-specific troponin
  • D. High-density lipoprotein (HDL) cholesterol
Correct Answer: C

Rationale: Troponin levels increase about 3-12 hours after the onset of myocardial infarction (MI). The other laboratory data are useful in determining the patient's risk for developing coronary artery disease (CAD) but are not helpful in determining whether an acute MI is in progress.
