A client develops frequent watery diarrhea, fever, and abdominal cramping after broad-spectrum antibiotic therapy and asks for loperamide. Which response should the nurse give?
1Take loperamide now because fever confirms uncomplicated nonspecific diarrhea.
2Avoid loperamide and contact the provider promptly for Clostridioides difficile evaluation.✓ Correct answer
3Take repeated loperamide doses until bowel sounds and stools completely stop.
4Delay reporting the symptoms until one week after the antibiotic course ends.
Explanation
Watery diarrhea, fever, and cramping after broad-spectrum antibiotics are concerning for Clostridioides difficile-associated pseudomembranous colitis. Loperamide is contraindicated in this setting because suppressing intestinal motility can contribute to serious complications. The client should avoid loperamide and contact the provider promptly for diagnostic evaluation, hydration assessment, and cause-directed treatment rather than delaying care.
Clinical reasoning Antimotility therapy can retain toxins and worsen colonic dilation when antibiotic-associated pseudomembranous colitis is present. Fever and cramping make nonspecific self-treatment unsafe.
Decision rule Do not use loperamide for suspected C. difficile colitis; obtain prompt clinical evaluation and treat the underlying infection and fluid losses.
Scenario 70-year-old female 2 weeks after clindamycin for dental infection presents with profuse watery diarrhea, cramping, fever 38.3°C. C. difficile assay pending.
Clostridioides difficile infection — Antibiotic-associated colitis that can cause watery diarrhea, fever, abdominal pain, dehydration, and toxic megacolon.
Antimotility agent — A drug such as loperamide that slows intestinal movement and is contraindicated in pseudomembranous colitis.
Toxic megacolon — Massive dilation of colon with sepsis; loperamide and antimotility agents are precipitants.
