NURS 3000: Physiology of Defecation and Elimination Needs

They increase abdominal pressure, which helps to expel feces from the body.

Expansion of the rectum to accommodate accumulated feces and eventual loss of sensitivity to the need to defecate, leading to constipation.

<p>The client should be encouraged to consume oral fluids and bland food, eat small amounts, and avoid excessively hot or cold fluids and highly spiced foods. This is because small amounts are more easily absorbed, and excessively hot or cold fluids and highly spiced foods can stimulate peristalsis and exacerbate diarrhea.</p> Signup and view all the answers

<p>Regular exercise helps clients develop a regular defecation pattern, and specific exercises such as tightening abdominal muscles and contracting thigh muscles can help strengthen weak muscles and improve defecation.</p> Signup and view all the answers

<p>Carbonated beverages, drinking straws, and chewing gum should be avoided, as they increase the ingestion of air. Additionally, gas-forming foods such as cabbage, beans, onions, and cauliflower should be limited, as they can contribute to gas buildup and exacerbate flatulence.</p> Signup and view all the answers

<p>Fiber plays a crucial role in maintaining healthy gut function, and a diet rich in fiber can help promote regular defecation and prevent constipation. Fiber adds bulk to stool and helps to stimulate peristalsis, promoting the movement of food through the digestive system.</p> Signup and view all the answers

<p>A client with weak abdominal and pelvic muscles can improve their ability to use a bedpan by strengthening their thigh muscles through exercises such as contracting and relaxing the thigh muscles.
