Question 1 of 5
A nurse working in an obstetric practice should consider which fact when discussing medication use with pregnant patients?
Correct Answer: A
Rationale: Pregnancy boosts lung perfusion, increasing inhaled drug absorption (e.g., anesthetics), a pharmacokinetic shift to note. Excretion may slow later, but not universally. Oral absorption isn't broadly reduced-GI changes vary. Avoiding all drugs is impractical-some conditions need treatment. Inhaled absorption informs safe use.
Question 2 of 5
A 39-year-old man who suffered a work-related injury has chronic back pain. A morphine pain pump was implanted to control his chronic pain. Formerly, he had chronic diarrhea which is now much improved. What is the most likely explanation for this finding?
Correct Answer: B
Rationale: Morphine, an opioid, improves chronic diarrhea by increasing intestinal circular muscle tone . Opioids slow GI motility via μ-receptors, enhancing tone and reducing peristalsis. Option , improved motility, opposes this. Options , , and (E) weaken continence or motility, not fitting. This constipating effect explains the improvement, a common opioid side effect.

Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
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.
