A young adult who was in a motorcycle accident is brought to the emergency room with a closed head injury with suspected subdural hematoma.
Correct answer
B
Rationale
Morphine sulfate, a narcotic analgesic, causes CNS and respiratory depression, which is contraindicated in head injuries because it masks signs of increased intracranial pressure, such as altered consciousness or pupil changes. Promethazine is an antiemetic, docusate is a stool softener, and ranitidine prevents stress ulcers, none of which pose the same risk.
