A client with a long history of cirrhosis has anemia, leukopenia, and thrombocytopenia. In the context of cirrhosis, these three conditions are most likely caused by:

Hypersplenism.

Peptic ulcer disease.

Cholecystitis.

Esophageal varices.

Answer and Explanation

The Correct Answer is A

Choice A rationale
Hypersplenism is a condition often associated with cirrhosis, where the spleen becomes overactive. This leads to the destruction of blood cells, causing anemia (low red blood cells), leukopenia (low white blood cells), and thrombocytopenia (low platelets)1.
Choice B rationale
Peptic ulcer disease primarily affects the stomach and duodenum, leading to ulcers and bleeding. It does not typically cause anemia, leukopenia, and thrombocytopenia in the context of cirrhosis.
Choice C rationale
Cholecystitis is the inflammation of the gallbladder, usually due to gallstones. It does not cause the blood cell abnormalities seen in cirrhosis.
Choice D rationale
Esophageal varices are swollen veins in the esophagus that develop due to portal hypertension in cirrhosis. While they can cause bleeding, they do not directly cause anemia, leukopenia, and thrombocytopenia.

Correct Answer is C

Explanation

Choice A rationale
Urine specific gravity of 1.029 indicates concentrated urine, which is common in dehydration but not specific to prerenal AKI. It reflects the kidney’s ability to concentrate urine in response to fluid deficit.
Choice B rationale
BUN of 28 mg/dL can indicate dehydration or renal impairment. However, it is not as specific as creatinine in diagnosing prerenal AKI. BUN can be elevated due to other factors like high protein intake or gastrointestinal bleeding.
Choice C rationale
Creatinine of 2.4 mg/dL is a critical indicator of kidney function. Elevated creatinine levels are more specific to renal impairment, including prerenal AKI, as they reflect the kidney’s ability to filter waste products.
Choice D rationale
Dry mucous membranes are a sign of dehydration but are not specific to prerenal AKI. They indicate fluid volume deficit but do not directly reflect kidney function.

A. This intracellular substance can leak into the blood with cardiac cellular injury or death. B. Elevated serum levels of troponin occur because of sustained glycogenolysis. C. This substance is elevated when a patient has acute tubular necrosis. D. Serum elevation of this acute phase reactant occurs because of tissue injury.

Correct Answer is A

Explanation

Choice A rationale
Elevated serum levels of troponin indicate cardiac cellular injury or death. Troponin is a protein released into the bloodstream when heart muscle cells are damaged, such as during a myocardial infarction.
Choice B rationale
Sustained glycogenolysis does not cause elevated troponin levels. Glycogenolysis is the breakdown of glycogen to glucose, primarily occurring in the liver and muscles, not related to troponin release.
Choice C rationale
Acute tubular necrosis does not elevate troponin levels. This condition affects the renal tubules and is typically indicated by elevated creatinine and BUN levels.
Choice D rationale
Troponin is not an acute phase reactant. Acute phase reactants are proteins whose levels change in response to inflammation, such as C-reactive protein (CRP), not troponin.
