The nurse is checking the laboratory results on a client suspected of having a myocardial infarction (MI). Which of the following would provide the most specific information for this diagnosis?
A)
low density lipids (LDLs)
B)
CK-MB
C)
AST and ALT
D)
C-reactive protein
B
Explanation:
A)
Creatinine kinase-MB is the most specific for diagnosis of a MI; CK levels rise rapidly following the event and the MB fraction is specific to the heart muscle. LDLs identify a risk factor for coronary artery disease (CAD). AST and ALT are more specific to the liver. C-reactive protein indicates inflammation and is another screening test for CAD risk.
Application
Assessment
Physiological Integrity: Reduction of Risk Potential
