What is the primary purpose of using a CPAP machine for the treatment of obstructive sleep apnea (OSA)?
To deliver a continuous flow of air pressure to keep the airway open
To reduce daytime sleepiness
To improve sleep quality
To promote weight loss
The Correct Answer is A
A. Delivering a continuous flow of air pressure to keep the airway open is correct. CPAP (Continuous Positive Airway Pressure) prevents airway collapse during sleep, allowing for uninterrupted breathing and oxygenation.
B. Reducing daytime sleepiness is a benefit of CPAP use, but it is not its primary purpose—it is a secondary effect of improved oxygenation and sleep continuity.
C. Improving sleep quality also occurs with CPAP therapy, but this is an outcome rather than the primary purpose.
D. Promoting weight loss is not the function of CPAP therapy, though weight loss can help reduce OSA severity.

Explanation
A. A high-calorie, high-protein diet is recommended to prevent weight loss, but this is not the best answer related to breathing strategies.
B. Pursed-lip breathing helps control shortness of breath by slowing exhalation, preventing airway collapse, and improving oxygenation.
C. Abdominal breathing is helpful, but lying on the stomach is not an appropriate technique for emphysema management.
D. Clients with emphysema should get a flu shot annually to prevent respiratory infections.

Explanation
- Obtain intravenous (IV) access: IV access is necessary for administering medications, fluids, and emergency interventions.
- Obtain the client's family history: While family history is important for long-term cardiac risk assessment, it is not a priority in the acute phase of chest pain management.
- Apply continuous ECG monitoring: Continuous ECG monitoring is critical for detecting arrhythmias, ischemic changes, and potential myocardial infarction (MI).
- Administer O₂ to maintain oxygen saturation greater than 90%: Oxygen therapy is indicated in clients with suspected MI if their oxygen saturation is below 90% to prevent further myocardial ischemia.
