A nurse is caring for a client who has sustained a neurologic injury with increased intracranial pressure and decreased cerebral perfusion.
Which of the following will maintain cerebral perfusion pressure constant?

Choice A rationale

Anhidrosis, or the inability to sweat normally, is a potential side effect of anticholinergic agents. These medications block the action of acetylcholine, a neurotransmitter that stimulates sweat glands among other functions. If a patient taking an anticholinergic agent for Parkinson’s disease experiences anhidrosis, they should report it to their healthcare provider as it can lead to overheating and heat stroke.
Choice B rationale
Tremors are a common symptom of Parkinson’s disease, and anticholinergic medications are often used to help control them. Therefore, while tremors should be monitored, they are not typically a side effect that needs to be reported unless they worsen or become unmanageable.
Choice C rationale
Drooling can be a symptom of Parkinson’s disease, but it is not typically a side effect of anticholinergic medications. In fact, these medications can sometimes cause dry mouth.
Choice D rationale
Rigidity, like tremors, is a common symptom of Parkinson’s disease. Anticholinergic medications can help manage rigidity, so it is not typically a side effect that needs to be reported unless it worsens.

Choice A rationale

Decreased visual acuity can increase the risk of falls, which are a common cause of head injuries in older adults. Impaired vision can affect balance and coordination, making it more difficult for an individual to navigate their environment safely.
Choice B rationale
While motor vehicle crashes can certainly lead to head injuries, they are not one of the most common causes of head injuries in older adults. Falls are actually the leading cause of head injuries in this population.
Choice C rationale
Polypharmacy, or the use of multiple medications by a patient, is common in older adults and can increase the risk of falls and, consequently, head injuries. Certain medications can cause side effects such as dizziness or confusion, which can lead to falls.
Choice D rationale
Weakness, particularly in the lower body, can increase the risk of falls and subsequent head injuries in older adults. Lower body weakness can affect an individual’s balance and mobility, making falls more likely.
Choice E rationale
Chronic hypertension can lead to a variety of health complications, including an increased risk of falls and head injuries. Hypertension can cause dizziness and balance problems, which can increase the risk of falls.
