Question
A postoperative client on opioid pain medication is started on docusate sodium 100 mg PO BID. Which client statement reflects an accurate understanding of this medication?
1"This medication is used to slow diarrhea."
2"This medication softens stool so it's easier to pass, but it does not directly stimulate the bowel; I should also drink plenty of fluids and increase fiber."✓ Correct answer
3"This medication treats opioid overdose."
4"This medication will produce a bowel movement within 30 minutes."
Explanation
Correct (2): Docusate is a stool softener (surfactant) — lowers surface tension, allows water/fat to penetrate stool. Does not stimulate motility, often combined with senna in opioid-induced constipation. Effect over 1-3 days. (1) Not rapid. (3) Antidiarrheal class confusion. (4) Naloxone reverses opioid OD.
In-depth explanation
Memory Tip Docusate = "Softens, does not push." For opioid-induced constipation: combine with senna or use OIC-specific agents (methylnaltrexone, naloxegol).
Clinical scenario
Scenario 45-year-old male post-op day 1 on opioids for pain; docusate 100 mg PO BID ordered for constipation prevention.
Key concepts
Stool softener — Docusate; surfactant that softens stool; not a stimulant.
Opioid-induced constipation — Common opioid side effect; prophylactic stool softener + stimulant or PAMORA.
