NR 507 Week 5: Edapt: Gastroesophageal Reflux Disease:
Alterations in the Gastrointestinal System
Gastroesophageal reflux disease (GERD) is commonly associated with the loss of
muscle tone at the lower esophageal sphincter (LES). The LES is a muscular ring that
separates the esophagus from the stomach, and its relaxation or incompetence can
lead to the backward flow of stomach contents into the esophagus, causing the
symptoms characteristic of GERD, such as heartburn and regurgitation.
Reverse peristalsis, where the stomach contracts in the opposite direction of normal
peristalsis, is not a typical mechanism associated with GERD.
Excessive salivation and swallowing do not typically cause GERD. In fact,
swallowing can help clear refluxed material from the esophagus.
GERD is more related to issues with the LES and the reflux of acidic stomach
contents into the esophagus than the increased production of bile.
?????
, 1) When an individual consumes a very large meal, the nurse practitioner (NP)
knows the gastric emptying rate will be increased .
2) When an individual receives a hypertonic gastric tube feeding solution, the
NP knows the gastric emptying rate will be delayed .
1. Stomach secretes gastrin into bloodstream in response to meal.
2. Gastrin returns to stomach and stimulates muscle contraction and acid
production.
3. Partially digested food (chyme) moves into small intestine and stimulates
secretion of CCK and secretin into the blood.
4. CCK and secretin stimulate the secretion of digestive enzymes and
bicarbonate ions f rom the pancreas into the small intestines.
5. CCK also stimulates contraction of the gallbladder, which then releases
bile into the s mall intestine.
