The nurse is caring for a patient who presents to the emergency department with right-sided weakness and dysphasia. Which type of stroke would the nurse suspect?
Transient ischemic attack
Basilar artery syndrome
Left middle cerebral artery syndrome
Right middle cerebral artery syndrome
The Correct Answer is C
A. Transient ischemic attack (TIA): A TIA might cause transient symptoms similar to a stroke, including weakness and dysphasia, but it would not explain why the symptoms are localized to the right side of the body. Additionally, TIA symptoms typically resolve within 24 hours.
B. Basilar artery syndrome: This type of stroke affects the brain stem, resulting in symptoms such as double vision, vertigo, and ataxia, rather than localized right-sided weakness and dysphasia.
C. Left middle cerebral artery syndrome: The left middle cerebral artery (MCA) supplies blood to the left hemisphere of the brain, including areas that control language and motor function on the right side of the body. Thus, an infarct in this area often leads to right-sided weakness and dysphasia, making it the most likely suspect.
D. Right middle cerebral artery syndrome: This would typically result in left-sided weakness and possibly neglect, but not right-sided symptoms

Correct Answer is D
Explanation
A. “Take off work for the rest of the day to rest at home.": This advice is not adequate for such a high blood pressure reading, which indicates a hypertensive crisis that requires immediate medical intervention.
B. "Return to work and have your blood pressure rechecked in 2 days.": This is inappropriate as it delays necessary urgent medical evaluation and treatment.
C. "Take two doses of blood pressure medication right now.": Without medical supervision, this could be dangerous and is not appropriate in an emergency situation where the blood pressure is critically high.
D. "Sit quietly while we call 911 to request an ambulance.": A blood pressure of 220/120 mm Hg suggests a hypertensive emergency, which can lead to life-threatening complications like stroke or heart attack. The patient needs immediate medical attention, and calling 911 is the appropriate response.
Correct Answer is B
Explanation
A. Ensure an adequate potassium blood level.: While potassium levels are important, they are not the primary goal in a hypertensive emergency.
B. Gradually reduce BP.: In hypertensive emergencies, the goal is to gradually reduce blood pressure to avoid causing further damage to organs. Rapid reduction can lead to ischemia or stroke.
C. Negate the impact of sodium in the body.: Although reducing sodium intake is a general recommendation for hypertension management, it is not the immediate goal in an emergency situation.
D. Increase urine output.: While diuretics might be used, the main goal is the controlled reduction of blood pressure rather than just increasing urine output.
