Which of the Following is an Example of Metabolic Acidosis

Question

Which of the following is an example of metabolic acidosis with a respiratory compensation?
A) Morphine overdose and diuresis
B) Persistent vomiting and hypoventilation
C) Ketoacidosis and Kussmaul respirations
D) Hypocalcemic tetany and hyperventilation

Accepted Answer

Ketoacidosis is a condition where there is an excess of ketone bodies, resulting in metabolic acidosis. The body compensates for this by increasing the rate and depth of breathing, known as Kussmaul respirations, to exhale more carbon dioxide and decrease acid levels in the blood. This is an example of metabolic acidosis with respiratory compensation. Morphine overdose and diuresis (A) can lead to respiratory depression and metabolic alkalosis, not acidosis. Persistent vomiting and hypoventilation (B) can lead to metabolic alkalosis due to the loss of stomach acid and increased levels of carbon dioxide in the blood. Hypocalcemic tetany and hyperventilation (D) can lead to respiratory alkalosis, not acidosis.
