Answer to Question 1

ANS: C
Propofol and morphine, administered simultaneously, allow for greater control of the ICP than morphine alone. Propofol reduces cerebral blood flow and intracranial pressure, making it a use-ful sedative for neurosurgical patients. In fact, propofol has been shown to be more effective than fentanyl in reducing ICP in patients with traumatic brain injury.

Answer to Question 2

ANS: C
Neuroleptics, such as haloperidol, are routinely used to treat patients demonstrating extreme agi-tation and delirium. Propofol is a general anesthetic used for sedation. Fentanyl is a synthetic opioid that is approximately 100-150 times more potent than morphine. Lorazepam (Ativan) is the drug of choice for sedating mechanically ventilated patients in the ICU for longer than 24 hours.
