A client has been taking perphenazine (Trilafon) by mouth for two days and now displays the following: head turned to the side, neck arched at an angle, stiffness and muscle spasms in neck.
- A. Which PRN medication should the nurse expect to give for a client with extrapyramidal side effects from perphenazine?
- B. Promazine (Sparine).
- C. Biperiden (Akineton).
- D. Thiothixene (Navane).
- E. Haloperidol (Haldol).
Correct Answer: B
Rationale: Biperiden, an antiparkinsonian agent, counteracts extrapyramidal side effects (e.g., dystonia, stiffness) caused by antipsychotics like perphenazine. Promazine, thiothixene, and haloperidol are antipsychotics that could worsen these side effects.
