A 65-year-old patient is unresponsive after falling from standing.

The correct answers are B. Bradycardia, C. Hypertension, and F. Cheyne-Stokes respirations.

This question is testing recognition of increased intracranial pressure (ICP), specifically the classic findings known as Cushing’s triad and abnormal breathing patterns.

Why B and C are correct (Cushing’s Triad):

Cushing’s triad is a hallmark of increased ICP and includes:

Hypertension (widening pulse pressure)

Bradycardia

Irregular respirations

NREMT-aligned trauma guidelines state:

“Increasing intracranial pressure may present with hypertension and bradycardia.”

These are late and critical signs of brain herniation risk.

Why F is correct (Cheyne-Stokes respirations):

Cheyne-Stokes respirations are:

An abnormal breathing pattern (alternating periods of apnea and rapid breathing)

Associated with brain injury and increased ICP

Guidelines emphasize:

“Irregular breathing patterns such as Cheyne-Stokes may indicate brain injury.”

Why the other options are incorrect:

A. Tachycardia: Typically seen in shock, not increased ICP.

D. Hypotension: Suggests shock; ICP usually causes hypertension.

E. Kussmaul respirations: Associated with metabolic acidosis (e.g., diabetic ketoacidosis), not ICP.

Exact Extracts:

“Cushing’s triad includes hypertension, bradycardia, and irregular respirations.”

“Irregular respirations such as Cheyne-Stokes are associated with brain injury.”

“These findings indicate increasing intracranial pressure and possible herniation.”
