Final answer:
The nurse should question the medication order for antiemetics for a patient with increased ICP.
Step-by-step explanation:
The nurse should question the medication order for antiemetics for a patient with increased ICP. Antiemetics can cause sedation and drowsiness, which may further increase intracranial pressure.
Mannitol is a medication used to reduce ICP by drawing fluid out of the brain. Opioids for pain relief can also be used as they do not directly affect intracranial pressure. Laxatives are not contraindicated for a patient with increased ICP.
