A client presents with a possible bowel obstruction, and the nurse completes a detailed abdominal assessment. Which of the following clinical manifestations are consistent with a large bowel obstruction? (Select all that apply).
Profuse vomiting with fecal odor
Epigastric abdominal distention
Intermittent abdominal cramping
Ribbon-like stools or diarrhea
Metabolic acidosis
Severe fluid and electrolyte imbalance
Correct Answer : A,B,C,D,E,F
Choice A reason:Profuse vomiting with a fecal odor can occur in large bowel obstructions due to the backward flow of bowel contents.
Choice B reason:Epigastric abdominal distention is a common finding in bowel obstructions due to the accumulation of gas and fluids.
Choice C reason:Intermittent abdominal cramping results from the bowel's attempt to push contents through the obstructed area.
Choice D reason:Ribbon-like stools or diarrhea may occur if there is a partial obstruction allowing some contents to pass.
Choice E reason:Metabolic acidosis can develop due to the accumulation of lactic acid from tissue hypoxia and decreased perfusion.
Choice F reason:Severe fluid and electrolyte imbalance can result from vomiting and the inability to absorb fluids and nutrients properly.

Correct Answer is ["60"]
Explanation
- Step 1: Identify the required dose in grams. The client is scheduled to receive 30 grams of lactulose.
- Step 2: Identify the concentration of the available solution. The available solution contains 5 grams of lactulose per 10 mL.
- Step 3: Calculate the volume of solution needed to deliver the required dose. We can set up a proportion to solve for this:
- 5 grams is to 10 mL as 30 grams is to X mL.
- In other words, 5 g : 10 mL = 30 g : X mL.
- Step 4: Solve for X using cross-multiplication and division:
- Cross-multiplication gives us: 5 g × X mL = 30 g × 10 mL.
- Simplifying this gives us: 5X = 300.
- Dividing both sides by 5 gives us: X = 300 ÷ 5.
- Calculating the division gives us: X = 60.
60 mL of the lactulose solution should be poured into the medication cup to administer the required dose of 30 grams.
Correct Answer is C
Explanation
Choice A reason:Rescheduling the scan is not necessary unless there are other contraindications or scheduling conflicts.
Choice B reason:Sending a suction catheter is a precautionary measure, but it does not address the management of the feeding tube during the scan.
Choice C reason:Shutting off the feeding 30-60 minutes before the scan is a standard practice to reduce the risk of aspiration and to ensure that the stomach contents do not interfere with the imaging.
Choice D reason:Connecting the feeding tube to continuous suction is not typically required unless there is a specific concern for aspiration or gastric content management during the scan.
