Final answer:
A nurse should instruct a client with IBS to increase their intake of high-fiber foods, drink plenty of water, and engage in regular exercise. Limiting fluid intake, avoiding exercise, and eating large meals at once should be avoided.
Step-by-step explanation:
Instructions for Managing Irritable Bowel Syndrome (IBS)
A nurse providing teaching to a client with IBS should include several important dietary and lifestyle changes. The most important instruction is to increase the intake of high-fiber foods.
Foods rich in soluble fiber, such as those containing inulin or oligosaccharides, can alleviate symptoms of IBS by promoting regular bowel movements and reducing inflammation.
Insoluble fiber, found in whole wheat and wheat bran, helps add bulk to feces and encourages food waste to move through the digestive system, potentially correcting constipation.
Regular exercise is encouraged as it can help regulate bowel movements and relieve stress, which can exacerbate symptoms.
It is also recommended to drink plenty of water and adopt a healthy diet low in fat and refined carbohydrates while rich in fruits, vegetables, whole grains, and proteins.
The advice to 'Increase intake of high-fiber foods.' is the correct instruction to include in the teaching for a client with IBS. Limiting fluid intake, avoiding regular exercise, and consuming large meals at once are not recommended and can worsen symptoms.
