The nurse is caring for a patient who has developed severe constipation. What rationale does the nurse have for why the patient has also lost his or her appetite?
A) Ileogastric reflex
B) Intestinal–intestinal reflex
C) Peritoneointestinal reflex
D) Renointestinal reflex
A
Feedback:
The introduction of chyme or stretch to the large intestine slows stomach activity, known as the ileogastric reflex which explains why patients who are constipated have no appetite. The intestinal–intestinal reflex is triggered by irritation of a section of the small intestine causing cessation of activity above that section. Peritoneointestinal reflex results from irritation of the peritoneum while renointestinal reflex results from irritation or swelling of the renal capsule.
