Question 2: In addition to arterial blood gas, an ________ can also differentiate between possible causes.
Anion gapFractional sodium excretionSerum osmotic gapBase excess

Question 3: ________ analysis and other tests are required to separate the main causes.

Question 5: It is due to the accumulation of ketoacids (________) and reflects a severe shift from glycolysis to lipolysis for energy needs.
Ketogenic dietGluconeogenesisDiabetes mellitusKetosis

Question 6: It is most often caused by pulmonary problems, although head injuries, drugs (especially ________ and sedatives), and brain tumors can cause this acidemia.

Question 9: Acid consumption from poisoning, elevated levels of ________ in the blood, and chronically decreased production of bicarbonate may also produce metabolic acidosis.
