For a patient with ICP monitored by a fiberoptic catheter, which order is a priority?

• A. Administer the prescribed mannitol
• B. Perform hourly neurologic checks
• C. Take a complete set of vital signs
• D. Give an H2-receptor blocker

Answer: (A)

When intracranial pressure is elevated, the immediate goal is to reduce ICP to prevent brain herniation and preserve cerebral perfusion. Administering the prescribed mannitol is the best next action because it quickly lowers ICP by creating an osmotic gradient that pulls fluid out of swollen brain tissue into the bloodstream, reducing cerebral edema and pressure within minutes. This rapid intervention stabilizes the patient and allows ongoing assessment to continue safely. Ongoing hourly neurologic checks and vital signs remain essential for monitoring the patient and guiding further treatment, but they don’t address the acute threat as directly as lowering ICP with mannitol. An H2-receptor blocker does not affect intracranial pressure and isn’t a priority in this acute scenario. Be mindful of mannitol monitoring: watch for signs of fluid or electrolyte imbalance, hypotension, and ensure proper osmolality and urine output are tracked as part of the therapy.
