A 40-year-old client is admitted to the coronary care unit with chest pain and shortness of breath. The physician diagnosed an anterior wall myocardial infarction.
What tests should the nurse anticipate?
A . Reticulocyte count, creatinine phosphokinase (CPK)
B . Aspartate transaminase, alanine transaminase
C . Sedimentation rate, WBC count
D . Lactic dehydrogenase, CPK
Answer: D
Explanation:
(A) Reticulocyte count measures the number of immature erythrocytes. CPK is an enzyme released from injured myocardial tissue.
(B) Aspartate transaminase is an enzyme released from injured myocardial tissue. Alanine transaminase is an enzyme released for general tissue destruction, which is specific for liver injury.
(C) Sedimentation rate is a nonspecific test for inflammation.
(D) Lactic dehydrogenase and CPK are enzymes released from injured myocardial tissue.
