A nurse is caring for a patient prescribed docusate sodium for constipation prevention. Based on the pharmacologic action of docusate sodium, which nursing intervention best supports its therapeutic effect?

A. Suggest taking docusate sodium simultaneously with stimulant laxatives to maximize bowel movement: Combining docusate sodium with stimulant laxatives is unnecessary for routine constipation prevention and may increase the risk of diarrhea or cramping. Docusate works effectively on its own when adequate hydration is maintained. B. Administer the medication with minimal fluids to increase absorption of the medication: Docusate sodium is a stool softener that works by drawing water into the stool. Administering it with minimal fluids would reduce its effectiveness and may worsen constipation. C. Advise the patient to avoid physical activity while taking docusate sodium: Physical activity promotes normal bowel motility. Restricting activity is counterproductive and does not enhance the therapeutic effect of docusate. D. Encourage increased fluid intake to aid in softening the stool: Docusate sodium acts as a surfactant, allowing water and fats to penetrate the stool. Adequate fluid intake enhances this effect, making bowel movements softer and easier to pass, supporting the drug’s intended therapeutic outcome.
