BS stands for which term?

• A. Basal state
• B. Blood sugar
• C. Bronchial secretions
• D. Brain stem

Answer: (B)

In medical shorthand, BS is most commonly used to mean blood sugar—the glucose level in a patient’s blood. Clinicians routinely check the blood sugar to monitor energy availability for the body's cells and to manage conditions like diabetes, hypoglycemia, or hyperglycemia. So the best choice is blood sugar because it matches the everyday charting and lab-ordered checks you’d see in patient records. The other terms—basal state, bronchial secretions, and brain stem—aren’t the standard readings or notes abbreviated as BS in typical clinical documentation, making them much less likely interpretations in this context.
