Practice Question
Lena Mason, who has diabetes, is admitted in a stuporous condition. Her blood gases show a pH of 7.33, PaC02 of 40 mm Hg, and HC03- of 20 mEq/L. What type of acid-base imbalance does this patient have?
Answer Choices:
Correct Answer:
Metabolic acidosis, uncompensated
Rationale:
A pH of 7.33 (acidic) with a normal PaCO₂ (40 mm Hg) and decreased HCO₃⁻ (20 mEq/L) indicates metabolic acidosis without respiratory compensation.
This is common in diabetic ketoacidosis (DKA), where the kidneys cannot neutralize excess ketones.
