Non-Bicarbonate Buffer Systems — MCQs

Which of the following methods cannot be used to precipitate proteins?

What is the most important extracellular buffer?

The pH of body fluids is stabilized by buffer systems. Which of the following compounds is the most effective buffer at physiologic pH?

Hyperkalemia and metabolic acidosis are commonly associated with which type of renal tubular acidosis?

Assertion: In a patient with chronic kidney disease (CKD) and metabolic acidosis, sodium bicarbonate should be initiated to correct acidosis. Reason: Sodium bicarbonate therapy reduces the progression of kidney disease by decreasing tubular injury and slowing fibrosis.

A person with type 1 diabetes ran out of her prescription insulin and has not been able to inject insulin for the past 3 days. The patient is hyperventilating to compensate for her metabolic acidosis. Which of the following reactions explains this respiratory compensation for metabolic acidosis?

HCO3/H2CO3 is the best buffer because it is:

The transport of CO2 in the blood is primarily influenced by which of the following factors?

A hyperventilating patient has the following ABG values: pH=7.53, pCO2=20 mmHg, HCO3= 26 mEq/L. What is the most likely diagnosis?

What is the primary mechanism for maintaining acid-base balance during prolonged vomiting?
