A nurse is assisting with the care of a client who is receiving an IV infusion of dextrose 10% in water. The nurse should monitor the client for which of the following adverse effects?

Choice A reason: The small intestine is not the starting point of the digestive process. It is where most of the digestion and absorption of nutrients occurs after the food has been processed in the stomach.

Choice B reason: The rectum is the final section of the large intestine, where feces are stored before being expelled. It is not involved in the initial stages of digestion.

Choice C reason: The stomach is involved in the early stages of digestion, particularly in the breakdown of proteins, but it is not the starting point. Food enters the stomach after being ingested through the mouth.

Choice D reason: The mouth is the correct starting location for the digestive process. Here, ingestion takes place, and mechanical digestion begins with chewing, while chemical digestion starts with enzymes in the saliva breaking down carbohydrates.

Choice A reason: An upper GI endoscopy is typically performed to evaluate symptoms of persistent heartburn, as it allows direct visualization of the esophagus, stomach, and duodenum, which are commonly affected by conditions that cause heartburn.

Choice B reason: Flexible sigmoidoscopy is used to examine the lower part of the colon, which is not typically
associated with symptoms of heartburn.

Choice C reason: A colonoscopy is used to view the entire colon and is not the first choice for investigating heartburn,
as this symptom is not directly related to the colon.

Choice D reason: A lower GI series, or barium enema, is an X-ray examination of the large intestine, which includes the colon and rectum. It is not typically used to diagnose conditions that cause heartburn.
