What is the rationale for using continuous positive air pressure (CPAP) to treat sleep apnea?
Positive air pressure holds the mouth open.
Negative pressure holds airways closed.
Delivery of oxygen facilitates expiratory effort.
Alternating waves of air stimulate breathing.
The Correct Answer is D
The correct answer is choice D, alternating waves of air stimulate breathing. CPAP works by delivering a continuous stream of pressurized air through a mask, which is worn over the nose or nose and mouth while sleeping. This air pressure acts like a splint, holding the airway open and preventing it from collapsing during sleep. The alternating waves of air delivered by the CPAP machine help stimulate breathing, keeping the airway open and reducing the number of breathing pauses that occur during sleep. CPAP is a highly effective treatment for obstructive sleep apnea, a condition in which the airway becomes blocked during sleep, leading to breathing pauses and interrupted sleep. By keeping the airway open and stimulating breathing, CPAP helps to improve sleep quality, reduce daytime sleepiness, and improve overall health outcomes in people with sleep apnea.

Correct Answer is ["B","C","D"]
Explanation
The correct answer is choices B, C, and D.
When assessing respiratory rate, it is important to count for a full respiratory cycle, which includes both inhalation and exhalation. If the respiratory rate is regular, the nurse can count for 30 seconds and multiply by 2 to obtain the total number of breaths per minute. The nurse should also observe the depth and rhythm of the respirations, noting any abnormalities or changes. It is not recommended to pretend to take the radial pulse while assessing respiratory rate, as this can lead to inaccurate readings and is not a professional approach to care
Correct Answer is C
Explanation
The correct answer is choice C. Cyanosis. Cyanosis is a medical emergency and requires immediate action by the nurse. It indicates that the client is not receiving adequate oxygenation and can lead to respiratory failure if not addressed promptly. Pallor (Option A) and erythema (Option D) are concerning but are not immediate priorities compared to cyanosis. Jaundice (Option B) may indicate liver dysfunction but is not an immediate priority unless it is associated with other symptoms such as severe abdominal pain or altered mental status.
