Which statement is NOT part of the blast triad?

• A. Apnea
• B. Bradycardia
• C. Hypertension
• D. Hypotension

Answer: (C)

The blast triad describes the immediate life-threatening response seen after a blast: apnea, bradycardia, and hypotension. Apnea happens from airway/respiratory disruption, bradycardia is a reflex effect of the blast on the heart via vagal pathways, and hypotension reflects shock physiology and vascular injury. Hypertension does not fit this pattern; in the acute blast response, blood pressure is typically low rather than high. So the statement about hypertension is not part of the blast triad.
