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.

Answer and Explanation

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 A

Explanation

The correct answer is choice A. When assisting a client with a fractured hip to turn in bed, the nurse should plan to turn the client to the unaffected side, which is the right side. This helps to reduce pressure on the affected hip, minimize discomfort, and prevent further injury. Clients with hip fractures (choice B) can and should be turned with proper positioning and assistance. Keeping the client supine (choice C) for extended periods can lead to pressure ulcers, discomfort, and other complications. Repositioning the client to the left side (choice D) can cause additional pressure and discomfort on the affected hip. Therefore, turning the client to the right is the best option for repositioning a client with a fractured left hip who has been lying in the supine position for an extended period.

Correct Answer is ["0.2"]

Explanation

Each mL contains 5,000,000 units. Therefore, to administer 1,000,000 units, we need:

1,000,000 units / 5,000,000 units/mL = 0.2 mL

So, the nurse will give 0.2 mL of reconstituted penicillin G to the client.
