What is an appropriate diagnostic study for abdominal pain described as distended, bloated, that is improved after flatulence possibly related to large bowel obstruction?
Endoscopy
Colonoscopy
Ultrasound
KUB
The Correct Answer is D
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.

Explanation
Rationale:
A. Lifting restrictions are typically advised for 2–4 weeks after laparoscopic cholecystectomy, not immediately postoperatively.
B. Encouraging ambulation once the client is fully awake helps prevent complications such as atelectasis, deep vein thrombosis, and promotes bowel function.
C. Placing the client flat in a supine position can increase the risk of respiratory complications; semi-Fowler’s is preferred.
D. Offering ice cream is not appropriate immediately after surgery; clear liquids are usually initiated first to assess tolerance.
Correct Answer is D
Explanation
Rationale:
A. While bleeding is a potential risk of paracentesis, it is less common than infection.
B. This is not a typical complication of paracentesis.
C. Although large-volume paracentesis can occasionally affect kidney perfusion, renal failure is not the most common complication.
D. Infection of the peritoneal cavity (spontaneous bacterial peritonitis) is the most common and serious complication associated with paracentesis. Proper aseptic technique is essential to minimize this risk.
