Question 4 of 5

Correct Answer: B
Rationale: The patient with right-sided brain damage typically denies any deficits and has poor impulse control, leading to risk for injury when the patient attempts activities such as transferring from a bed to a chair.

Question 5 of 5
You are at Publix and see a woman collapsed with right-sided weakness and slurred speech. What should you do?
Correct Answer: B
Rationale: Right-sided weakness and slurred speech suggest a stroke. The priority is to call emergency services (e.g., 911) to ensure rapid professional assessment and treatment, such as thrombolysis if within the time window. Offering water risks aspiration, driving delays care, and carotid massage is irrelevant.
