A patient with hypoglycemia will often present with which of the following signs/symptoms?

• A. Hypertension
• B. Deep, rapid respirations
• C. Warm, red, and dry skin
• D. Pale, cool, and clammy skin

Answer: (D)

Hypoglycemia triggers a counter-regulatory sympathetic response that produces signs such as sweating and changes in skin color as blood flow is redirected to vital organs. The skin becoming pale, cool, and clammy is a classic hallmark of this response, reflecting vasoconstriction and adrenergic stimulation as the body tries to raise blood glucose and protect the brain.

Other signs listed don’t fit hypoglycemia as neatly. Deep, rapid respirations are more typical of metabolic acidosis conditions like diabetic ketoacidosis. Warm, red, and dry skin suggests fever, heat exposure, or hypermetabolic states rather than the adrenergic response seen in low glucose. Hypertension can accompany stress or pain but isn’t the characteristic skin presentation you’d expect with hypoglycemia.
