What is the rationale for using CPAP to treat sleep apnea?
A) Positive air pressure holds the airway open. B) Negative air pressure holds the airway closed. C) Delivery of oxygen facilitates respiratory effort. D) Alternating waves of air stimulate breathing. Ans: A Feedback: Continuous positive airway pressure (CPAP) is used to treat sleep apnea. The device, worn at night, delivers positive air pressure through a facemask to hold the airway open.
A nurse educates a young couple on putting their newborn on his back to sleep. What is the rationale for this 10. information?
