A patient with cerebral ischemia has signs and symptoms of right homonymous hemianopia and inability to move the right arm.
This is indicative of increased intracranial pressure that is most probably due to a lesion in the:
Left extrapyramidal tract.
Right cerebral hemisphere.
Cerebellum.
Left cerebral hemisphere.
The Correct Answer is D
Choice A rationale
The left extrapyramidal tract is involved in motor control, but lesions here would not cause right homonymous hemianopia or inability to move the right arm. These symptoms are more indicative of a lesion in the cerebral hemisphere.
Choice B rationale
A lesion in the right cerebral hemisphere would cause left-sided symptoms, not right-sided. The patient’s symptoms are indicative of a lesion in the left cerebral hemisphere.
Choice C rationale
The cerebellum is involved in coordination and balance, not in causing right homonymous hemianopia or inability to move the right arm. These symptoms are more indicative of a lesion in the cerebral hemisphere.
Choice D rationale
A lesion in the left cerebral hemisphere can cause right homonymous hemianopia and inability to move the right arm. This is because the left hemisphere controls the right side of the body and processes visual information from the right visual field.

Correct Answer is C
Explanation
Choice A rationale
A hemorrhagic brain attack (stroke) is less common than an ischemic brain attack. Ischemic strokes account for the majority of strokes.
Choice B rationale
Thrombolytic drugs are used to treat ischemic strokes, not hemorrhagic strokes. They do not cause hyper-reactive reflexes.
Choice C rationale
A hemorrhagic brain attack requires immediate intervention to prevent further damage. Hemorrhagic strokes involve bleeding in the brain, which can rapidly worsen and cause severe damage.
Choice D rationale
An ischemic brain attack is not necessarily less severe than a hemorrhagic brain attack. Both types of strokes are serious, but hemorrhagic strokes often require more urgent intervention due to the risk of ongoing bleeding.
Correct Answer is A
Explanation
Choice A rationale
Administering antihypertensive medication as prescribed is the priority action for a client with a history of hypertension presenting with severe headache, blurred vision, and confusion.
These symptoms suggest a hypertensive crisis, which requires immediate blood pressure reduction to prevent further complications.
Choice B rationale
Preparing the client for a lumbar puncture is not the priority action in this scenario. While a lumbar puncture may be necessary to rule out other conditions, the immediate concern is to manage the hypertensive crisis.
Choice C rationale
Initiating seizure precautions is important if the client is at risk of seizures, but the priority action is to address the hypertensive crisis by administering antihypertensive medication.
Choice D rationale
Monitoring the client’s blood glucose levels is important for overall health management, but it is not the priority action in this scenario. The immediate concern is to manage the hypertensive crisis.
