A nurse is assisting with teaching a newly licensed nurse about the function of the large intestine. Which of the following information should the nurse include?
It produces vitamin D.
It absorbs liquid to form stool.
It secretes enzymes to digest food.
It prevents the reflux of food into the esophagus.
The Correct Answer is B
A. It produces vitamin D: The skin, not the large intestine, produces vitamin D when exposed to sunlight.
B. It absorbs liquid to form stool: The large intestine reabsorbs water and electrolytes, forming solid stool.
C. It secretes enzymes to digest food: Enzyme secretion for digestion occurs in the stomach and small intestine, not the large intestine.
D. It prevents the reflux of food into the esophagus: The esophageal sphincter prevents reflux, not the large intestine.

Correct Answer is A
Explanation
A. Add fluid and fiber to the diet: Increasing dietary fiber and fluid promotes stool bulk and softening, aiding in bowel movement regularity.
B. Avoid gas-producing foods: This helps with bloating but does not address constipation.
C. Request that the provider prescribe a stool softener: This is a secondary intervention after nonpharmacological methods, such as diet and hydration, have been attempted.
D. Promote active range-of-motion activities: While physical activity helps prevent constipation, active range-of-motion exercises are less effective compared to fluid and fiber intake.
Correct Answer is D
Explanation
A. Reflex incontinence: Reflex incontinence occurs due to involuntary bladder contractions, not retention, and doesn't necessarily indicate the need for catheterization.
B. Nocturnal enuresis: Nighttime incontinence is a symptom but does not indicate immediate need for catheterization unless associated with retention or discomfort.
C. Urge incontinence: This indicates overactivity of the bladder rather than retention; catheterization isn't typically necessary unless retention follows the urge.
D. Suprapubic discomfort: Suprapubic discomfort suggests bladder distention, indicating the need for catheterization to relieve retention and prevent complications like urinary tract infections.
