Which of the following lipoproteins is primarily responsible for transporting cholesterol from peripheral tissues back to the liver for excretion or reprocessing, earning it the nickname 'good cholesterol'?

Chylomicrons transport dietary fats, VLDL transports triglycerides from the liver, and LDL transports cholesterol to peripheral tissues ('bad cholesterol').

A patient's arterial blood gas (ABG) analysis shows pH 7.28, PaCO2 30 mmHg, and HCO3- 15 mEq/L. This pattern is most consistent with:

Accepted Answer

A. Metabolic acidosis with respiratory compensation. — A pH of 7.28 indicates acidosis (normal 7.35-7.45). A low HCO3- (bicarbonate, normal 22-26 mEq/L) points to a metabolic cause. The low PaCO2 (carbon dioxide, normal 35-45 mmHg) indicates hyperventilation, which is the body's respiratory compensation to blow off CO2 and try to raise the pH in response to metabolic acidosis.
