Nutrition, Hydration and Electrolytes · NCLEX Exam

Why is hydration and electrolyte support important for a patient preparing for a colonoscopy on clear liquids?

  1. Clear liquids always supply sufficient electrolytes on their own
  2. Fasting and bowel prep cause fluid/electrolyte loss needing support
  3. Electrolyte levels remain entirely unaffected by bowel preparation
  4. No special attention is needed since the procedure is brief
Show answer and explanation

Correct answer: Fasting and bowel prep cause fluid/electrolyte loss needing support
