Answer to Question 1
ANS: A
Anti-hypertensive medications may be detrimental because the mean arterial pressure must be adequate to maintain cerebral blood flow and limit secondary injury. Fever can worsen the outcome after a stroke, and antipyretics can promote normothermia. Osmotic diuretics such as mannitol can decrease interstitial volume and decrease intracranial pressure. Short-acting sedatives can decrease intracranial pressure by reducing metabolic demand. Long-acting sedatives would be avoided to provide times for periodic neurologic assessments.
Answer to Question 2
ANS: D
Injury prevention measures such as wearing a seat belt, helmet use, firearm safety, and violence prevention programs reduce the risk of traumatic brain injuries. Blood pressure control and exercising can decrease the risk of vascular disease, impacting the cerebral arteries, rather than head injuries. Smoking cessation is one primary prevention strategy which can decrease the risk of vascular disease. Maintaining a healthy weight can decrease the risk of vascular disease.
