Answer to Question 1

ANS: D
Tachypnea is the cardinal sign of increased work of breathing.

Answer to Question 2

The patient is in hypoxic (type I) and hypercapnic (type II) acute respiratory failure. Providing full mechanical ventilatory support will provide the ventilator support needed to normalize pH and improve oxygenation.
