Which of the following is NOT a component of Cushing's Triad?

• A. Hypotension
• B. Bradycardia
• C. Hypertension
• D. Irregular respirations

Answer: (A)

Cushing’s Triad reflects signs of increased intracranial pressure. The three components are hypertension (elevated systolic blood pressure), bradycardia (slow heart rate), and irregular or abnormal respirations. The feature that does not fit the triad is low blood pressure. When ICP rises, the body raises systemic blood pressure to keep cerebral perfusion, the baroreceptor reflex slows the heart, and brainstem irritation causes irregular breathing. If you see hypotension, it suggests a process other than classic increased ICP, such as shock or hemorrhage, rather than the Cushing’s pattern.
