Which of the following is NOT a common factor that would affect a 75-year-old patient's vital signs?

• A. Medications
• B. Increased weight
• C. Overall health
• D. Medical conditions

Answer: (B)

Vital signs reflect the body's current physiological state and are shaped by factors that directly alter heart rate, blood pressure, temperature, and respiratory rate. Medications can markedly influence these measures—for example, some drugs raise or lower blood pressure or heart rate, and others can affect temperature or respiration. A person’s overall health and any medical conditions also play a direct role: infections typically raise temperature and pulse, dehydration can cause tachycardia and low blood pressure, and endocrine or cardiovascular diseases can shift baseline vitals. Increased weight, by itself, doesn’t usually cause immediate, direct changes in vital signs during a routine assessment; it’s more of a long-term risk factor that can contribute to conditions affecting vitals, rather than a direct, acute determinant. So the factor that isn’t a common direct influence on vitals is the increased weight.
