Sample item

What is the primary disturbance in metabolic alkalosis?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Raised bicarbonate

This item reviews Acid base; Raised bicarbonate is the best answer because it directly fits the anatomical or physiological relationship described.

Option by option

  • A. Low pH only

    Low pH only is not supported by the key finding.

  • B. Raised bicarbonate (correct)

    Correct. Raised bicarbonate matches the defining feature.

  • C. Raised PaCO2 only

    Raised PaCO2 only does not match the stated relationship.

  • D. Low bicarbonate

    Low bicarbonate is plausible but is not the best answer.
