Answer to Question 1

D
Hypoxemia is an insufficient amount of oxygen in the blood.

Answer to Question 2

A
Feedback:
A tracheostomy tube may have a balloon cuff; when inflated, the cuff seals the upper airway to prevent aspiration of oral fluids and provide more efficient ventilation. An oral airway is a curved device that keeps a relaxed tongue positioned forward within the mouth, preventing the tongue from obstructing the upper airway. During insertion of a tracheostomy tube, an obturator, a curved guide, is used. Most clients with tracheostomy tubes require frequent suctioning.
