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 B

Explanation

: Bring a narrow beam of light from the side of the patient's face and briefly shine the light on the pupil, observing the pupil for constriction. This is the appropriate technique to assess pupillary reaction. The nurse should stand to the side of the patient and use a penlight or other focused light source to illuminate one pupil at a time. The light should be directed from the side of the eye, not directly in front of it, to avoid stimulating the accommodation reflex. The nurse should observe for constriction of the pupil, which should occur in response to the light. This assessment is important because changes in pupil size and reactivity can indicate neurological dysfunction or other medical conditions.

A. The nurse identifies the patient has pain and formulates this as the patient's priority health problem. B. The nurse removes bandages from a burn victim's arm and performs sterile dressing change once a shift. C. The nurse ambulates a post-operative patient in the hall during their shift. D. The nurse assesses a patient to determine their nutritional status. E. The nurse turns a patient every 2 hours to prevent pressure injuries.

Correct Answer is ["C","E"]

Explanation

The nursing actions that best represent the step of performing interventions in the nursing process are:

C. The nurse ambulates a post-operative patient in the hall during their shift.

E. The nurse turns a patient every 2 hours to prevent pressure injuries.

Explanation: In the step of performing interventions, the nurse takes action to implement the nursing care plan and achieve the identified goals. The interventions should be specific, measurable, and realistic to address the patient's needs. Ambulating a post-operative patient in the hall during their shift and turning a patient every 2 hours to prevent pressure injuries are both specific interventions that address patient needs and promote positive health outcomes. Removing bandages from a burn victim's arm and performing sterile dressing change once a shift is more related to the step of assessment or implementation, while identifying a patient's priority health problem or assessing a patient's nutritional status are more related to the step of analysis and diagnosis in the nursing process.
