Which of the following is NOT one of the five vital signs?

• A. Respiratory Rate
• B. Blood Pressure
• C. Heart Rate
• D. Blood Sugar

Answer: (D)

Vital signs are key indicators of a patient's essential bodily functions and health status, commonly measured in medical settings to assess overall health. The traditional five vital signs include body temperature, pulse (heart rate), respiration rate, blood pressure, and oxygen saturation.

Blood sugar, while an important indicator of metabolic status and is frequently monitored, especially in patients with conditions such as diabetes, is not classified as one of the primary vital signs. The primary vital signs focus on the functionality of the cardiovascular and respiratory systems rather than metabolic measurements. Therefore, blood sugar does not fit within the accepted category of vital signs, distinguishing it clearly from respiratory rate, blood pressure, and heart rate, all of which are essential parameters routinely assessed in clinical practice to evaluate acute and overall health.
