A client with severe diarrhea asks the nurse why so much water is being expelled with each bowel movement. The nurse explains that:
1. the intestines are not reabsorbing sufficient fluid.
2. the client needs to take a laxative at this time.
3. the intestines are reabsorbing too much fluid.
4. peristalsis is too slow.
Correct Answer: 1
Rationale 1: Diarrhea occurs when the small or large intestine fails to reabsorb sufficient fluid.
Rationale 2: Laxatives would be contraindicated in a client who is having severe diarrhea.
Rationale 3: If the intestines are reabsorbing too much fluid, the likely outcome is constipation.
Rationale 4: When the client has diarrhea, peristalsis is too fast for the fluids to be reabsorbed.
Global Rationale: Diarrhea occurs when the small or large intestine fails to reabsorb sufficient fluid. Peristalsis is too fast in this condition. There is no reason for the patient to take a laxative.
