A 28-year-old woman with schizoaffective disorder (combination of mood and psychotic symptoms) reports difficulty falling asleep. Which of the following would be most beneficial in this patient?

Correct Answer: D

Rationale: Paliperidone, a second-generation antipsychotic, treats schizoaffective disorder's psychotic and mood symptoms via D2 and 5HT2 antagonism. Its moderate sedative effect, less than chlorpromazine's, can aid sleep onset without excessive drowsiness, fitting her insomnia complaint. Lithium stabilizes mood but doesn't sedate or address psychosis directly. Chlorpromazine, a sedating first-generation antipsychotic, risks oversedation and EPS. Haloperidol, non-sedating, controls psychosis but not mood or sleep. Ziprasidone lacks strong sedation. Paliperidone's balanced profile manages her condition holistically, improving sleep while targeting core symptoms, per evidence.

Correct Answer: C

Rationale: Potassium chloride corrects hypokalemia but is caustic IV, risking phlebitis or tissue damage if it infiltrates. Monitoring the IV site prevents complications, a key precaution. Undiluted or rapid infusion causes burns or arrhythmias'standard is diluted, <10 mEq/hour. A syringe pump isn't required'IV pumps suffice. Site monitoring aligns with potassium's administration risks, critical in hypokalemia where cardiac effects (e.g., arrhythmias) are at stake, making C the nurse's priority to ensure safe delivery.
