Option A: Cardiac monitoring, oxygen, and creatine kinase, and lactate dehydrogenase levels are appropriate for a cardiac primary problem. A basic metabolic panel and alkaline phosphatase and aspartate aminotransferase levels assess liver function. Option B: Prothrombin time, partial thromboplastin time, fibrinogen and fibrin split products are measured to verify bleeding dyscrasias. Option D: An electroencephalogram evaluates brain electrical activity. 3. Question Olivia had coronary artery bypass graft (CABG) surgery 3 days ago.
