To maintain normal elimination patterns in a hospitalized patient, why should the nurse encourage the patient to take time to defecate 1 hour after meals?
a. The presence of food stimulates peristalsis.
b. Mass colonic peristalsis occurs at this time.
c. Irregularity helps to develop a habitual pattern.
d. Neglecting the urge to defecate can cause diarrhea.
B
Defecation is most likely to occur after meals. If the patient attempts to defecate during the time when mass colonic peristalsis occurs, the chances of successfully evacuating the rectum are greater. When stool reaches the rectum, distention causes relaxation of the internal sphincter and awareness of the need to defecate. Establishing a consistent time for bowel hygiene is one evidenced-based practice to avoid constipation. Ignoring the urge to defecate and not taking time to defecate completely are common causes of constipation.
