Final answer:
Preoperative testing for Mr. Robertson typically includes a CBC, EKG, Chest X-ray, and Serum creatinine measurement, but not an endocardium, which is actually part of the heart not a diagnostic test.
Step-by-step explanation:
The preoperative testing for Mr. Robertson would include various tests to assess his health status before undergoing surgery. However, one test that is not standard in preoperative testing regimens is an endocardium, which is not a test but rather the inner lining of the heart chambers.Tests commonly included in preoperative evaluations are a Complete Blood Count (CBC), to check for anemia and other blood disorders; an Electrocardiogram (ECG or EKG), which measures the electrical impulses in the heart and can detect heart disease; a Chest X-ray, to visualize the lungs and heart, and observe any abnormalities; and a Serum creatinine measurement, assessing the kidneys' function.
