Question 1 of 5
The nurse is reviewing the chart of a client with a diagnosis of unstable angina. Which laboratory test(s) result(s) should the nurse recognize as an Indication of heart damage? (SELECT ALL THAT APPLY)
Correct Answer: B,D
Rationale: The correct answers are B (Elevated troponins) and D (Elevated CK-M
B). Elevated troponins indicate heart muscle damage, specifically myocardial injury. CK-MB is an enzyme released when there is damage to heart muscle cells. Both troponins and CK-MB are used as cardiac markers to assess heart damage in conditions like unstable angina. Increased platelet count (
A) is not a direct indicator of heart damage. Decreased homocysteine levels (
C) are not specifically related to heart damage in the context of unstable angina. Decreased alkaline phosphatase (ALT) (E) is a liver enzyme and does not directly reflect heart damage.
