Which type of enema is typically used to relieve constipation by instilling and retaining fluid for a short period before expelling?
Lactulose Enema
Fleet Enema
Tap water enema
Mineral Enema
The Correct Answer is B

B. A Fleet enema is a hypertonic solution that draws fluid into the colon, is retained briefly, and promotes rapid evacuation of stool to relieve constipation.
C. Tap water enemas are hypotonic and typically require immediate expulsion, not short retention.
D. Mineral oil enemas are retention enemas, meant to soften stool over a longer period, not for rapid evacuation.

Correct Answer is D
Explanation
Rationale:
A. Used to visualize the upper gastrointestinal tract (esophagus, stomach, duodenum). It does not provide information about bowel obstruction in the large intestine.
B. Allows direct visualization of the colon mucosa but is not typically used initially in suspected acute bowel obstruction due to the risk of perforation.
C. Useful for evaluating gallbladder, liver, kidneys, and sometimes bowel, but it is less sensitive for detecting large bowel obstruction.
D. A plain abdominal X-ray (KUB) is often the first-line diagnostic study for suspected large bowel obstruction. It can show dilated bowel loops, air-fluid levels, and fecal loading, which correlate with the patient’s symptoms of bloating, distention, and relief after flatulence.
Correct Answer is ["A","B","D"]
Explanation
Rationale:
A. Probiotics, such as yogurt with live cultures, can promote healthy gut flora and improve bowel regularity.
B. Physical activity stimulates peristalsis, helping prevent constipation, especially in clients who have reduced mobility postoperatively.
C. Low-fiber foods worsen constipation. Clients should consume high-fiber foods such as fruits, vegetables, and whole grains to promote bowel movements.
D. Adequate hydration softens stool and prevents fecal impaction, particularly important for clients taking opioid pain medications.
E. Drinking warm or hot liquids can actually help stimulate bowel movements. There is no need to avoid them.
