Question

Nurse is reviewing lab findings of patient who developed chest pain six hours ago. Nurse should identify which of the following findings as an indication of a myocardial infarction?

A. Calcium of 9.5
B. High density lipoprotein HDL of 65
C. ALT of 28
D. Troponin I of 8

Answer 1

The nurse should identify a Troponin I level of 8 as an indication of a myocardial infarction.

Step-by-step explanation:

Myocardial infarction (MI), commonly known as a heart attack, occurs when the blood supply to a part of the heart muscle is blocked, leading to damage or death of the heart muscle cells. The blockage is often caused by the formation of a blood clot in a coronary artery, which supplies oxygen and nutrients to the heart. Myocardial infarction is a medical emergency that requires prompt intervention to minimize damage to the heart muscle.

An MI can be confirmed by examining the patient's ECG, which frequently reveals alterations in the ST and Q components. Common blood tests indicating an MI include elevated levels of creatine kinase MB and cardiac troponin. Based on the lab findings provided, the nurse should identify a Troponin I level of 8 as an indication of a myocardial infarction.
