A nurse is caring for a client who reports chest pain. Which of the following laboratory findings indicates myocardial damage?
Troponin 11.8 ng/mL
Erythrocyte sedimentation rate (ESR) 17 mm/hr
Human B-type natriuretic peptide 88 pg/ml.
aPTT 80 seconds
The Correct Answer is A
A.
A. Troponin is a protein released into the bloodstream when there is damage to the heart muscle (myocardium), such as during a heart attack. Elevated troponin levels indicate myocardial injury or damage, making this the correct choice for indicating myocardial damage.
B. Erythrocyte sedimentation rate (ESR) measures the rate at which red blood cells settle in a tube of blood. It is a non-specific marker of inflammation and is not specific to myocardial damage.
C. Human B-type natriuretic peptide (BNP) is released by the heart in response to increased pressure and volume. Elevated levels are indicative of heart failure, not necessarily myocardial damage.
D. Activated partial thromboplastin time (aPTT) measures the time it takes for blood to clot. It is used to monitor the effectiveness of anticoagulant therapy and is not specific to myocardial
damage.

B. The infant's head turns away from the light - This would not be an expected finding during a vision screening; it may suggest a different reflex or issue.
C. The infant's eyes remain focused toward the floor - This would not be an expected finding during a vision screening; it may suggest a different visual or developmental concern.
D. The infant closes their eyes - Closing the eyes in response to light is not the typical response during a vision screening for infants.
