Question
A nurse teaches a client about polyethylene glycol (PEG-electrolyte) preparation for colonoscopy the next morning. Which statement indicates effective teaching?
1Refrigeration is not necessary
2Drink the entire solution within 30 minutes
3Add fruit juice with red dye to improve taste
4Drink the solution in 240 mL portions every 10-15 minutes as a split dose (half the evening before, half 4-6 hours before procedure); expect frequent watery stools✓ Correct answer
Explanation
Correct (2): PEG-electrolyte solution is best taken as a split dose (half evening before, half 4-6 hours before scope) in 240 mL aliquots every 10-15 min. Outcomes superior to single dose. Refrigeration is OK to improve palatability (but no red/purple dye that mimics blood on scope). (1) Causes nausea/aspiration. (3) Refrigeration helps. (4) Red dye obscures findings.
In-depth explanation
Memory Tip PEG colonoscopy prep = "Split dose, Cold OK, NO Red." Stop solids and start clear liquid diet day before; clear stool target.
Clinical scenario
Scenario 52-year-old male preparing for screening colonoscopy AM; prescribed PEG 4 L split-dose. Outpatient teaching.
