ARTERIAL BLOOD GAS
INTERPRETATION FOR
NCLEX QUIZ 2
1. Question
In acid-base balance, the normal plasma PCO2 and bicarbonate
levels are disturbed. Match the changes in this parameter with
the disorders in the given choices: Low plasma PaCO2
o A. Metabolic Acidosis
o B. Respiratory Alkalosis
o C. Metabolic Alkalosis
o D. Respiratory Acidosis
Correct Answer: B. Respiratory Alkalosis
Excessive pulmonary ventilation decreases hydrogen ion
concentration and thus causes respiratory alkalosis. It can
become dangerous when it leads to cardiac dysrhythmias caused
partly by a decrease in serum potassium levels.
2. 2. Question
In acid-base balance, the normal plasma PCO2 and bicarbonate
levels are disturbed. Match the changes in this parameter with
the disorders in the given choices: High plasma PaCO2
o A. Metabolic Acidosis
o B. Respiratory Alkalosis
o C. Metabolic Alkalosis
o D. Respiratory Acidosis
, Correct Answer: D. Respiratory Acidosis
An excess of carbon dioxide (hypercapnia) can cause carbon
dioxide narcosis. In this condition, carbon dioxide levels are so
high that they no longer stimulate respirations but depress them.
3. 3. Question
In acid-base balance, the normal plasma PCO2 and bicarbonate
levels are disturbed. Match the changes in this parameter with
the disorders in the given choices: Decreased plasma
bicarbonate (HCO3-)
o A. Metabolic Acidosis
o B. Respiratory Alkalosis
o C. Metabolic Alkalosis
o D. Respiratory Acidosis
Correct Answer: A. Metabolic Acidosis
The body compensates by using body fat for energy, producing
abnormal amounts of ketone bodies. In an effort to neutralize the
ketones and maintain the acid-base balance of the body, plasma
bicarbonate is exhausted. This condition can develop in anyone
who does not eat an adequate diet and whose body fat must be
burned for energy. Symptoms include headache and mental
dullness.
4. 4. Question
In acid-base balance, the normal plasma PCO2 and bicarbonate
levels are disturbed. Match the changes in this parameter with
the disorders in the given choices: Increased plasma
bicarbonate (HCO3-)
o A. Metabolic Acidosis
o B. Respiratory Alkalosis
o C. Metabolic Alkalosis
