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.

Correct Answer is B
Explanation
Rationale:
A. Delaying discussion until after signing the consent form does not address the client’s immediate anxiety or provide needed education.
B. Providing information about sedation reassures the client that discomfort during the colonoscopy will be minimized and helps reduce anxiety. It is accurate, therapeutic, and informative.
C. Acknowledging the recommendation without addressing the anxiety does not provide reassurance or information about pain management.
D. While humorous, this comment does not address the client’s concern about pain and is not considered a therapeutic response.
Correct Answer is B
Explanation
Rationale:
A. Replacing lost blood components requires blood products, not isotonic crystalloids.
B. Isotonic crystalloid fluids (e.g., 0.9% sodium chloride, lactated Ringer’s) are administered to restore extracellular fluid volume in clients with fluid volume deficit.
C. While isotonic solutions contain electrolytes, their primary purpose is volume replacement, not rapid electrolyte correction.
D. Correcting metabolic acidosis may require specific interventions; isotonic fluids alone do not address acid-base imbalances.
