Which of the following is NOT a part of a complete physical exam?

A complete physical exam typically includes several components aimed at assessing the overall health of a patient. Among these components, height measurement is standard as it helps track growth and health status. EKGs (electrocardiograms) are commonly performed to evaluate heart health, particularly in older adults or those with specific risk factors. Urinalysis is also a routine part of many physical exams as it provides critical information about kidney function and metabolic processes.

Visual acuity testing, however, while important, is not universally included in all comprehensive physical exams. It is often specifically reserved for eye exams or situations where there's a known concern regarding vision. Thus, visual acuity testing is not considered a standard element of a complete physical exam like the other options mentioned. This context clarifies why visual acuity for adults stands out as the correct answer in this scenario.
