A 58-year-old male patient with a history of colon cancer has developed jaundice. Which laboratory finding would most likely suggest liver metastasis as the cause of the jaundice?

Increased creatinine levels

Elevated serum amylase

Decreased albumin levels

Elevated serum bilirubin level

Answer and Explanation

The Correct Answer is D

A.   Increased creatinine levels may indicate kidney dysfunction, but it is not specifically related to liver metastasis.
B.   Elevated serum amylase is typically associated with pancreatic conditions and not directly with liver metastasis.
C.   Decreased albumin levels may occur with liver dysfunction but is not specific to liver metastasis.
D.   Elevated serum bilirubin levels are a key indicator of liver dysfunction, and when seen in the context of jaundice and a history of colon cancer, they strongly suggest liver metastasis as the underlying cause.

Correct Answer is C

Explanation

A. Dextrose 10% in water is hypertonic and would exacerbate hypernatremia by further increasing sodium levels.
B. 25% albumin is not appropriate for treating hypernatremia and is typically used for volume expansion in cases of shock or hypoalbuminemia.
C. Dextrose 5% in water is an isotonic solution that helps dilute sodium levels and correct hypernatremia gradually.
D. Dextran 40 is a volume-expanding agent, not suitable for treating hypernatremia.

A. Blood glucose level of 140 mg/dL with low insulin levels. B. Blood glucose level of 180 mg/dL with normal ketone levels. C. Blood glucose level of 250 mg/dL with normal ketone levels. D. Blood glucose level of 600 mg/dL with elevated ketone levels in blood and urine.

Correct Answer is D

Explanation

A. A blood glucose level of 140 mg/dL is too low for DKA, which typically involves hyperglycemia above 250 mg/dL.
B. A blood glucose level of 180 mg/dL and normal ketone levels are inconsistent with DKA, as DKA involves both high glucose and elevated ketones.
C. A blood glucose level of 250 mg/dL with normal ketone levels would not suggest DKA. Elevated ketones are a critical part of diagnosing DKA.
D. A blood glucose level of 600 mg/dL with elevated ketone levels in blood and urine confirms DKA, a life-threatening complication of Type 1 diabetes.
