Answer to Question 1

ANS: C
Retractions are defined as the sinking of soft tissue relative to the cartilaginous or bony thorax. Retractions can be extreme in severe airway obstruction as the work of breathing increases. Grunting can be a sign of pain in older children with respiratory issues. It serves to increase the end-respiratory pressure, which prolongs the period of oxygen and carbon dioxide exchange across the membrane. Tachypnea is an increase in the respiratory rate above the child's baseline. Nasal flaring, the enlargement of the nostrils, helps reduce nasal resistance and maintains airway patency.

Answer to Question 2

ANS: B
Room air is composed of 21 oxygen, trace amounts of carbon dioxide, and 79 nitrogen.
