Gastrointestinal illnesses cause symptoms of anorexia, vomiting, and diarrhea. Which lab value should the nurse monitor related to volume depletion?

Carcinoembryonic Antigen (CEA)

B12 Level

Electrolyte imbalance

Hemoglobin level

Answer and Explanation

The Correct Answer is C

Choice A rationale
Carcinoembryonic Antigen (CEA) is a protein used as a tumor marker, particularly for cancers of the gastrointestinal tract. It is not directly related to volume depletion caused by gastrointestinal illnesses.
Choice B rationale
B12 level is important for nerve function and the formation of red blood cells. It is not directly related to volume depletion caused by gastrointestinal illnesses.
Choice C rationale
Electrolyte imbalance is the correct answer. Gastrointestinal illnesses often cause symptoms such as vomiting and diarrhea, which can lead to significant loss of fluids and electrolytes.
Monitoring electrolyte levels is crucial in these cases to prevent complications related to volume depletion.

Choice D rationale
Hemoglobin level is an indicator of the amount of oxygen-carrying protein in the blood. While it is an important lab value, it is not the most relevant in the context of volume depletion due to gastrointestinal illnesses.

Correct Answer is D

Explanation

Choice A rationale
It is normal to have a sore throat following an EGD procedure. The endoscope is passed down the throat, which can cause temporary discomfort.
Choice B rationale
Patients do need someone to drive them home after an EGD. The sedatives used during the procedure can impair their ability to drive safely.
Choice C rationale
Patients will be left side-lying with the head of the bed elevated during the procedure. This position helps to prevent aspiration.
Choice D rationale
Patients cannot drink immediately after the procedure. They must wait until their gag reflex has returned, which can take a few hours.

A. Irritable bowel syndrome B. Crohn’s disease C. Gastric ulcers D. Gastroesophageal reflux disease (GERD)

Correct Answer is C

Explanation

Choice A rationale

Sucralfate is not commonly used to treat irritable bowel syndrome. Irritable bowel syndrome is typically managed with dietary modifications, stress management, and medications to control specific symptoms such as constipation or diarrhea.

Choice B rationale

Sucralfate is not commonly used to treat Crohn’s disease. Crohn’s disease is an inflammatory bowel disease that is typically managed with anti-inflammatory medications, immune system suppressors, and antibiotics.

Choice C rationale

Sucralfate is commonly used to treat gastric ulcers. It works by forming a protective barrier over the ulcer, which helps protect the ulcer from further damage by stomach acid and allows it to heal.

Choice D rationale

While sucralfate can be used to treat symptoms of gastroesophageal reflux disease (GERD), it is not the first-line treatment. Other medications, such as proton pump inhibitors and H2 blockers, are typically used first.
