A nurse is caring for a hospital client who is to undergo a sigmoidoscopy. Which of the following should the nurse administer to cleanse the bowel in preparation?
A) Tap water and normal saline solution
B) Tap water and soap solution
C) Hypertonic saline solution
D) Cottonseed or olive oil solution
A
Feedback:
Tap water and normal saline solution is preferred for cleansing the bowel in preparation for a rectal examination because of its nonirritating effects. A combination of tap water and soap solution is not suitable because soap causes chemical irritation of the mucous membranes. A concentrated hypertonic saline solution also acts as a local irritant on the mucous membranes. Cottonseed or olive oil solution is not normally used for this purpose.
