"The medication increases dopamine levels in your brain."

"The medication decreases acetylcholine levels in your brain."

"The medication increases serotonin levels in your brain."

"The medication decreases glutamate levels in your brain."

Answer and Explanation

The Correct Answer is A

Choice A reason:

This is a correct answer, as the medication increases dopamine levels in the brain, which helps to improve the symptoms of Parkinson's disease, such as tremors, rigidity, and bradykinesia.

Choice B reason:

This is an incorrect answer, as the medication does not decrease acetylcholine levels in the brain, but rather increases dopamine levels. Acetylcholine is another neurotransmitter that controls muscle contraction, learning, and memory.

Choice C reason:

This is an incorrect answer, as the medication does not increase serotonin levels in the brain, but rather increases dopamine levels. Serotonin is another neurotransmitter that controls mood, sleep, and appetite.

Choice D reason:

This is an incorrect answer, as the medication does not decrease glutamate levels in the brain, but rather increases dopamine levels. Glutamate is another neurotransmitter that controls excitatory signals in the brain.

A. Elevate the head of the bed to 30 degrees. B. Administer mannitol as prescribed. C. Monitor the client's intracranial pressure. D. All of the above.

Correct Answer is D

Explanation

Choice A reason:

This is correct because elevating the head of the bed to 30 degrees can help reduce intracranial pressure by facilitating venous drainage and decreasing cerebral blood volume.

Choice B reason:

This is correct because administering mannitol as prescribed can help reduce intracranial pressure by creating an osmotic gradient that draws fluid out of the brain tissue and into the bloodstream.

Choice C reason:

This is correct because monitoring the client's intracranial pressure can help detect any signs of increased intracranial pressure or cerebral herniation, which can be life-threatening complications of cerebral edema.

Choice D reason:

This is correct because all of the above interventions are appropriate for a client who has ischemic stroke and is at risk for cerebral edema.
