[bobbysung]

A child with croup has an increased PCO2 a decreased pH, and a normal HCO3 blood gas value. The nurse interprets this as uncompensated:
 
  1. Respiratory acidosis.
  2. Respiratory alkalosis.
  3. Metabolic acidosis.
  4. Metabolic alkalosis.

Question 2

A nurse is analyzing assessment findings on four different newborns. Which assessment finding on a newborn might suggest a congenital heart defect?
 
  1. Apical heart rate of 140 beats per minute
  2. Respiratory rate of 40
  3. Acrocyanosis
  4. Cyanosis of the buccal membranes

Answer to Question 1

1
Rationale:
1. If the pH is decreased and the PCO2 is increased with a normal HCO3, it is uncompensated respiratory acidosis. Also, croup can be a disease process that causes respiratory acidosis.
2. Respiratory alkalosis, uncompensated, has an increased pH, decreased PCO2, and normal HCO3.
3. Metabolic acidosis, uncompensated, has a decreased pH, normal PCO2, and normal HCO3.
4. Metabolic alkalosis, uncompensated, has an increased pH, normal PCO2, and increased HCO3.

Answer to Question 2

4
Rationale:
1. Apical heart rate of 140 is a normal assessment finding for newborns.
2. Respiratory rate of 40 is a normal assessment finding for newborns.
3. Acrocyanosis (cyanosis of the extremities) is a normal assessment finding for newborns.
4. Cyanosis of the buccal membranes is not a normal finding in a newborn, and could indicate a congenital heart defect.
