Question
Metabolic acidosis is associated with decreased plasma level of:
- (A) bicarbonate
- (B) lactate
- (C) oxygen
- (D) urea
Solution
Metabolic acidosis is a condition that occurs when the body produces excessive quantities of acid or when the kidneys are not removing enough acid from the body.
The answer to your question is (A) bicarbonate.
Here's why:
-
Metabolic acidosis is characterized by a decrease in plasma bicarbonate concentration. Bicarbonate is a form of carbon dioxide (CO2), a gas waste left when your body burns food for energy. Bicarbonate in your blood naturally buffers acid. In metabolic acidosis, the level of bicarbonate in the blood is lower than normal.
-
Lactate (B) is not decreased in metabolic acidosis. In fact, lactic acidosis, a subtype of metabolic acidosis, is characterized by increased levels of lactate.
-
Oxygen (C) levels are not directly affected by metabolic acidosis. However, severe acidosis can lead to tissue hypoxia.
-
Urea (D) is a waste product formed in the liver, passed to the kidneys and is then excreted in the urine. Its level is not directly affected by metabolic acidosis.
So, the correct answer is (A) bicarbonate.
