Arterial Blood Gas Interpretation Challenge
Exam (Quiz #1: 20 Questions)
1. 1. Question
1 point(s)
R
In acid-base balance, the normal plasma PCO2 and bicarbonate levels are disturbed. Match the
E
changes in this parameter with the disorders in the given choices: Low plasma PaCO2
○ A. Metabolic Acidosis
H
○ B. Respiratory Alkalosis
○ C. Metabolic Alkalosis
G
○ D. Respiratory Acidosis
I
.
Correct Answer: B. Respiratory Alkalosis
H
Excessive pulmonary ventilation decreases hydrogen ion concentration and thus causes
respiratory alkalosis. It can become dangerous when it leads to cardiac dysrhythmias caused
G
partly by a decrease in serum potassium levels.

In acid-base balance, the normal plasma PCO2 and bicarbonate levels are disturbed. Match the
Y
changes in this parameter with the disorders in the given choices: High plasma PaCO2
L
○ A. Metabolic Acidosis
○ B. Respiratory Alkalosis
F
○ C. Metabolic Alkalosis
○ D. Respiratory Acidosis
Correct
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
1 point(s)
, 2
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-)
○ A. Metabolic Acidosis
○ B. Respiratory Alkalosis
○ C. Metabolic Alkalosis
R
○ D. Respiratory Acidosis
E
.
Correct Answer: A. Metabolic Acidosis
H
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,
G
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
I
mental dullness.
4. 4. Question
H
1 point(s)
G
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
N
bicarbonate (HCO3-)
I
○ A. Metabolic Acidosis
○ B. Respiratory Alkalosis
○ C. Metabolic Alkalosis
Y
○ D. Respiratory Acidosis
L
Correct
F
Correct Answer: C. Metabolic Alkalosis
In metabolic alkalosis, breathing becomes depressed in an effort to conserve carbon dioxide for
combination with water in the blood to raise the blood level of carbonic acid. Symptoms include
confusion, dizziness, numbness or tingling of fingers or toes.
5. 5. Question
1 point(s)
What two organs in the body serve as a compensatory function to maintain acid-base balance?
○ A. Kidneys and Lungs
