Question Of The Day: Neurosensory Disorders

Q. A client is receiving an I.V. infusion of mannitol (Osmitrol) after undergoing intracranial surgery to remove a brain tumor. To determine whether this drug is producing its therapeutic effect, the nurse should consider which finding most significant?

A. Decreased level of consciousness (LOC)
B. Elevated blood pressure
C. Increased urine output
D. Decreased heart rate

Correct Answer: C
Explanation: The therapeutic effect of mannitol is diuresis, which is confirmed by an increased urine output. A decreased LOC and elevated blood pressure may indicate lack of therapeutic effectiveness. A decreased heart rate doesn't indicate that mannitol is effective.
