Clinical Decision-Making (CDM) Cases Part I Practice Test

The idea being tested is that routine preoperative laboratory testing isn’t automatically required for healthy, non-pregnant adults. Guidelines encourage ordering labs only when there’s a specific indication based on the patient’s history, exam, age, comorbidities, or the expected blood loss of the surgery.

In this context, many routine panels like lipid panels and liver function tests aren’t routinely necessary for a healthy non-female patient undergoing low-risk surgery. The nuance is how transfusion readiness is handled: a Type and Screen is a test used to anticipate and manage potential transfusion needs, but it isn’t universally mandated for all such patients. Therefore, the option that reflects a test category not strictly required by guidelines for this group is the Type and Screen only.

So, the best answer emphasizes that broad preoperative lab testing isn’t required, and Type and Screen is not a universal prerequisite for non-female patients, whereas the other listed lab tests aren’t automatically mandated either, but the phrasing highlights the Type and Screen as not strictly required in this scenario.
