Which combination describes Cushing's triad?

Which combination describes Cushing's triad?

• A. Decreased heart rate, increased BP, increased/irregular respiratory rate
• B. Increased heart rate, decreased BP, regular respiratory rate
• C. Decreased heart rate, decreased BP, increased respiratory rate
• D. Normal heart rate with normal BP and respirations

Answer: (A)

Cushing's triad signals rising intracranial pressure and poor brain perfusion, shown by a combination of hypertension (increased blood pressure), bradycardia (decreased heart rate), and irregular or abnormal respirations. The correct pattern reflects bradycardia, hypertension, and irregular respirations, which is why it matches the triad. Other patterns (such as tachycardia with hypotension or normal vitals) do not indicate this ICP-related response. In practice, recognize this as a late, concerning sign requiring rapid assessment, airway support, and transport.
