A patient who was in a motor vehicle accident sustained a severe head injury and is brought to the emergency department. The provider orders intravenous mannitol (Osmitrol). The nurse knows that this is given to:
Reduce intracranial pressure.
Reduce peripheral edema.
Restore extracellular fluid.
Reduce renal perfusion.
The Correct Answer is A
Choice A reason: Mannitol, an osmotic diuretic, reduces intracranial pressure by drawing fluid from brain tissue into the bloodstream. This is its primary use in head injuries, making it correct.
Choice B reason: Mannitol is not primarily for peripheral edema; it targets cerebral edema. Furosemide is used for peripheral fluid, so this is incorrect for mannitol’s purpose.
Choice C reason: Mannitol removes fluid, not restores it. extracellular fluid, aiming to reduce brain swelling. Restoring fluid is opposite its effect, so this is incorrect.
Choice D reason: Mannitol increases renal perfusion by promoting diuresis, not reducing it. Its main goal is intracranial pressure reduction, so this is incorrect.
