Question

A nurse in an emergency department is caring for a client who reports substernal chest pain and dyspnea. The client is vomiting and is diaphoretic. Which of the following laboratory tests are used to diagnose a MI (select all that apply)

A. Troponin I
B. Troponin T
C. Plasma low-density (LDL)
D. CPK
E. Myoglobin

Answer 1

The laboratory tests used to diagnose a Myocardial Infarction (MI) are Troponin I, Troponin T, CPK, and Myoglobin.

Step-by-step explanation:

When diagnosing a Myocardial Infarction (MI), certain laboratory tests are used to confirm the presence of a heart attack. These tests include:

• Troponin I: This protein is released into the blood when there is damage to the heart muscle. It is one of the most common tests used to diagnose an MI.
• Troponin T: Similar to Troponin I, Troponin T is another protein released when there is heart muscle damage. It is also used as a diagnostic test for an MI.
• CPK (Creatine Phosphokinase): This enzyme increases in the blood shortly after a heart attack and is considered an early marker for diagnosing an MI.
• Myoglobin: Myoglobin is a protein found in cardiac muscle cells. Elevated levels of myoglobin in the blood can indicate heart muscle damage.
