Question 1

Which lipoprotein is considered protective against cardiovascular disease?

Accepted Answer

HDL

Answer

HDL (high-density lipoprotein) transports cholesterol from peripheral tissues back to the liver (reverse cholesterol transport), reducing atherosclerosis risk.

Question 2

A serum sodium of 125 mEq/L with dilute urine in a cancer patient suggests which diagnosis?

Accepted Answer

SIADH

Answer

SIADH (syndrome of inappropriate ADH) causes hyponatremia with inappropriately concentrated urine, commonly paraneoplastic.

Question 3

Which test is used to evaluate liver synthetic function?

Accepted Answer

Prothrombin time (PT)

Answer

The liver synthesizes clotting factors, so PT/INR elevation indicates impaired hepatic synthetic function.

Question 4

Elevated serum alkaline phosphatase (ALP) with normal transaminases is MOST consistent with which condition?

Accepted Answer

Obstructive jaundice or bone disease

Answer

An isolated ALP elevation suggests cholestasis or bone disease; GGT elevation alongside confirms hepatic origin.

Question 5

In a blood gas analysis, a pH of 7.28 with elevated pCO2 and normal HCO3 indicates which acid-base disorder?

Accepted Answer

Respiratory acidosis

Answer

Low pH with elevated pCO2 (retained CO2) and normal bicarbonate indicates respiratory acidosis from hypoventilation.
