Tactile hallucinations (B) involve false sensations, and persecutory delusions (D) involve belief in harm without reference to neutral stimuli.

- A. Narcotic analgesics cause mydriasis, which will raise intracranial pressure.
- B. Narcotic analgesics are not effective for pain caused by brain trauma.
