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 B
Explanation
A. Elevated blood pressure: Hypotension, not hypertension, is more likely during severe transfusion reactions.
B. Wheezing: Wheezing indicates an allergic reaction due to hypersensitivity to proteins in the donor blood.
C. Distended neck veins: This is a sign of fluid overload, not an allergic reaction.
D. Flank pain: Flank pain is associated with hemolytic reactions, not allergic reactions.
Correct Answer is C
Explanation
A. Immediately before meals: Although the gastrocolic reflex is stimulated after eating, taking the client immediately before meals does not align with the natural defecation reflex.
B. Every 2 hr while the patient is awake: This does not consider the client’s natural bowel patterns and may lead to frustration or noncompliance.
C. When the client has the urge to defecate: Bowel training is most effective when timed to coincide with the client's natural urge to defecate, promoting a routine and reducing the risk of constipation or incontinence.
D. After the client feels abdominal cramping: Cramping could indicate discomfort from gas or constipation, not necessarily the optimal time for defecation.
