Final answer:
The indicated problem is metabolic acidosis.
Step-by-step explanation:
In the case where PaO2 is 93, pH is 7.36, PaCO2 is 28, and HCO3 is 14, it indicates a metabolic acidosis.
A pH value below the normal range indicates acidosis. Since the pH value is 7.36, which is below 7.35, it indicates acidosis. Additionally, the HCO3 value is 14, which is below the normal range of 22-29 mM, further supporting the diagnosis of metabolic acidosis.
The low HCO3 value in metabolic acidosis suggests a primary deficit in bicarbonate, which can be caused by conditions such as renal failure, diabetic ketoacidosis, or lactic acidosis. In this case, further investigation is needed to determine the specific cause.
