Introduce what a physical examination is, and the basics on how to perform one in a patient-centred way as a group discussion. Discuss proper technique, the importance of consent, privacy, draping and use of appropriate medical equipment (i.e., stethoscope, blood pressure cuff, etc.) Introduce Vital Signs, including normal and abnormal values. Discuss factors that affect vital signs. Pro comp connection: Patients of Varying Body Habitus. Patients presenting to medical professionals for clinical care represent a variety of body habituses. Body mass index (BMI) is used as a clinical indicator of body habitus, calculated based on a person’s height and weight. Patients are classified according to their BMI as underweight (BMI <18.5), normal weight (BMI 18.5-24.9), overweight (25.0-29.9) and obese (>30.0). Note that although BMI is used clinically, it was originally a population health measure and was derived from a homogenous group (Belgian population). Therefore, its utility for individual patient care may be limited. Epidemiological studies have shown a correlation where the risk of hypertension, type 2 diabetes, sleep apnea, cancer and a variety of other conditions increases as BMI increases; therefore, the classification system is meant to capture increasing health risks. It is important to note that a causal relationship between BMI and these health conditions has not been shown.
