I.PCO₂
II.pH
III.PO₂

Question

Quizplus · Accepted Answer

When an ABG sample is left at room temperature, cellular metabolism continues, consuming oxygen (O2) and producing carbon dioxide (CO2), leading to a decrease in pH. However, the question incorrectly labels the options, making it unclear what I, II, and III represent. Typically, in such a scenario, pCO2 would increase, and pH would decrease.
