The nurse is providing patient teaching to a patient newly diagnosed with sleep apnea. The patient asks the nurse how it works to correct his sleep apnea. Which is the most appropriate statement by the nurse?
1. "The machine is set up to breathe for you when you stop breathing during the night."
2. "The machine's positive airway pressure provides a reminder to breathe during periods of apnea. "
3. "The machine's positive airway pressure keeps the upper airway structures from collapsing during sleep."
4. "The machine is set to give you oxygen during the times when you stop breathing and keep you from snoring."
Answer: 3
Explanation: The continuous positive airway pressure prevents the upper airway structures from collapsing during sleep. The machine does not breathe for the patient. CPAP does not remind the patient to breathe, although it may be set o alarm if breathing does not resume within a set time. Though some patients may receive oxygen, it is not set up to deliver oxygen only when the patient stops breathing. CPAP will likely decrease snoring but that is not its primary purpose.
