Answer to Question 1

ANS: C
Retained CO2 creates H+ byproducts that lower pH. This sends a chemical signal to increase respiratory rate and would result in increased ventilation. All other options would cause the ventilation rate to normalize or decrease to increase carbon dioxide retention or as the result of delivery of higher levels of oxygen to tissues.

Answer to Question 2

ANS: A
A C4 injury would result in damage to the phrenic nerve and would cause a decrease in inspiratory lung expansion. Accessory muscles will also be damaged by a C4 injury. The patient may exhibit decreased perfusion and increased hemoglobin to compensate for hypoxemia.
