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
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
While headaches can be a side effect of many medications, they are not commonly associated with daily aspirin intake.
Choice B rationale
Muscle pain is not a common side effect of daily aspirin intake. It is more commonly associated with statins, a class of drugs used to lower cholesterol levels.
Choice C rationale
Increased appetite is not a known side effect of daily aspirin intake.
Choice D rationale
Stomach upset is a potential adverse effect of taking daily aspirin. Aspirin can irritate the stomach lining, which can lead to symptoms such as heartburn and nausea.
Correct Answer is C
Explanation
Choice A rationale
Aspartate aminotransferase (AST) is an enzyme that is found in various tissues, including the liver. Elevated levels of AST can indicate liver damage or disease.
Choice B rationale
Albumin is a protein that is made by the liver. It helps keep fluid in the bloodstream so it doesn’t leak into other tissues. Low levels of albumin can indicate liver disease.
Choice C rationale
Lipase is an enzyme that is produced by the pancreas and used in the digestion of fats. It is not a marker of liver function.
Choice D rationale
Alanine transaminase (ALT) is an enzyme found mostly in the cells of the liver and kidney. Much like AST, high levels of ALT can indicate liver damage or disease.
