1. 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
Incorrect
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
Incorrect
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
Incorrect
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
o D. Respiratory Acidosis
Incorrect
Correct Answer: C. Metabolic Alkalosis
