Question

you are caring for a 90-year-old patient who you believe may have had a stroke. the patient has slurred speech, facial paralysis, and left body paralysis. which of the following would lead you to suspect the patients stroke is continuing to get worse?

the development of an irregular pulse.
a significant increase in blood pressure.
a decrease in respiratory rate from 24 to 20.
a radiating pain to the jaw and down the left arm.

Analyze the clinical scenario

Using the Stroke Clinical Presentation knowledge point, we identify a 90-year-old patient showing classic signs of an acute stroke: slurred speech, facial paralysis, and left-sided hemiplegia. We need to determine which clinical sign indicates that the stroke is actively worsening.

Evaluate intracranial pressure dynamics

Using the Stroke Pathophysiology knowledge point, a worsening stroke (such as an expanding hemorrhagic stroke or large ischemic edema) leads to increased intracranial pressure (ICP). The body compensates for high ICP by raising systemic blood pressure to maintain cerebral perfusion pressure. This physiological response is part of Cushing's triad (hypertension, bradycardia, and irregular respirations). Therefore, a significant increase in blood pressure is a key indicator of worsening intracranial pathology.

Rule out incorrect options

• An irregular pulse may indicate atrial fibrillation (a risk factor for embolic stroke) but does not directly signal acute worsening of the stroke itself.
• A decrease in respiratory rate from 24 to 20 represents a normalization of tachypnea rather than deterioration.
• Radiating pain to the jaw and left arm is a classic sign of acute coronary syndrome (myocardial infarction), not a worsening stroke.
