Why would bag and mask ventilation be contraindicated in resuscitation of a neonate with CDH?
 
  a. It results in air swallowing, which enlarges the stomach and compresses lung tissue.
  b. It requires too much effort for the respiratory therapist to manually squeeze the bag.
  c. The FIO2s delivered by the device can cause oxygen toxicity and ROP.
  d. The high tidal volumes may result in pulmonary interstitial emphysema.

Question 2

A patient with severe kyphoscoliosis and chronic ventilatory failure with hypoxemia will have all of the following laboratory findings, EXCEPT:
 
  a. increased PaCO2.
  b. increased hematocrit.
  c. normal pH.
  d. increased pH.

Answer to Question 1

A
Bag and mask ventilation should not be used on a newborn with CDH. It could result in air swallowing, which expands the stomach and intestines and further compresses the affected lung.

Answer to Question 2

D
In a patient with chronic ventilatory failure with hypoxemia, the PaCO2 will be increased with a normal pH because of metabolic compensation. Because of the chronic hypoxemia, the body compensates by increasing the hematocrit (and hemoglobin).
