Question 1 of 5

Ms. Jackson has been suffering from persistent vomiting for two days. She appears to be lethargic and weak and has myalgia. She is noted to have dry mucous membranes and her capillary refill time takes more than 4 seconds. She is diagnosed with gastroenteritis and dehydration. Measurement of arterial blood gas shows pH 7.5, PaO2 85 mm Hg, PaCO2 40 mm Hg, and HCO3 34 mmol/L. What acid base disorder is shown?

Correct Answer: D
