Identify the patient’s support system and coping strategies
Interventions
Pain
Imbalanced Nutrition: Less Than Body Requirements
Ineffective Coping

Question 22

is a condition where ingested foods bypass the stomach too rapidly and enter the small intestine largely undigested. It happens when the small intestine expands too quickly due to the presence of hyperosmolar (having increasedosmolarity) contents from thestomach. This causes symptoms due to the fluid shift into the gut lumen with plasma volume contraction and acute intestinal distention

Answer 22

Dumping syndrome

Question 23

“Early” dumping begins concurrently within ? min from ingestion of a meal

Answer 23

15 to 30 minutes

Question 24

“Late” dumping happens ? hours after eating.

Symptoms of late dumping include weakness, sweating, and dizziness. Many people have both types. The syndrome is most often associated withgastric bypass(Roux-en-Y) surgery.

Question 26

In addition, people with this syndrome often suffer from What?, because the rapid “dumping” of food triggers thepancreasto release excessive amounts ofWhat?into the bloodstream. This type of hypoglycemia is referred to as ?
