DISORDERS OF THE GASTROINTESTINAL SYSTEM
Nausea and VomitingNausea is an unpleasant feeling that vomiting is
imminent. Vomiting is an involuntary act in which thestomachcontractsandforcefullyexpelsgastriccontents.

LAXATIVES
General Nursing Implications— Laxatives should be avoided in clients who have nausea, vomiting, undiagnosed abdominal pain and cramping, and/or any indications of appendicitis.— Dietary fiber should be taken for prevention of, and as first-line treatment for, constipation.— Encourage increase in daily fluid intake. — Increasing activity will increase peristalsis and decrease constipation.— Narcotic analgesics and anticholinergics will increase problem with constipation.— A laxative should be used only briefly and in the smallest amount necessary.— Use laxatives with caution during pregnancy.

Clinical Tips for Problem SolvingIf water does not flow easily into colostomy stoma:
• Checkforkinksintubingfromcontainer.
• Checkheightofirrigatingcontainer.
• Encourageclienttochangepositions,relax,andtakeafewdeepbreaths.
If client experiences cramping, nausea, or dizziness during irrigation:
• Stopflowofwater,leavingirrigationconeinplace.
• Donotresumeuntilcrampinghaspassed.
• Checkwatertemperatureandheightofwaterbag;ifwateristoohotorflowstoorapidly,itcancausedizziness.
