When considering the pharmacologic management of a patient who has sustained a traumatic head injury, the nurse can anticipate a prescription for which of the following medications to manage increases in intracranial pressure (ICP)?
Nitroprusside
Furosemide
3% Normal Saline
Norepinephrine
The Correct Answer is C
A. Nitroprusside is a vasodilator and is not used for managing ICP; it can increase intracranial pressure if not carefully monitored.
B. Furosemide is a diuretic but is less effective for ICP reduction compared to hypertonic saline or mannitol.
C. Hypertonic saline (3% Normal Saline) is used to reduce intracranial pressure by drawing fluid out of the brain tissue and into the bloodstream, which can help prevent cerebral edema.
D. Norepinephrine is a vasopressor and is not used specifically to manage intracranial pressure.
