A nurse is assisting with teaching a client who has obstructive sleep apnea (OSA) about continuous positive airway pressure (CPAP). Which of the following instructions should the nurse include?

The CPAP device should fit loosely on the face.

The CPAP device delivers less pressure during exhalation than inhalation.

The CPAP device requires an invasive ventilation tube.

The CPAP device should be placed over the nose.

Answer and Explanation

The Correct Answer is D

Choice A rationale:
The CPAP device should not fit loosely on the face. It should fit snugly to create a proper seal and maintain positive airway pressure. A loose-fitting CPAP mask may not effectively treat obstructive sleep apnea (OSA).
Choice B rationale:
The CPAP device typically delivers consistent pressure throughout both inhalation and exhalation. It does not deliver less pressure during exhalation. The purpose of CPAP is to maintain a constant pressure to keep the airway open during both phases of the respiratory cycle.
Choice C rationale:
The CPAP device does not require an invasive ventilation tube. It uses a mask that covers the nose or both the nose and mouth to deliver positive airway pressure. It is non-invasive and is designed to keep the airway open by delivering pressurized air.

Correct Answer is A

Explanation

There are three types of sleep apnea: obstructive, central, and mixed complex. Obstructive apnea is the most common type. It is caused by the relaxation of the soft tissues, which allows partial to total obstruction of the airway. (True or False) = The correct answer is True.

Choice A rationale:

True. Obstructive sleep apnea is indeed the most common type. It occurs when the soft tissues in the throat and the muscles of the upper airway relax too much during sleep, leading to a partial or complete blockage of the airway. This obstruction results in the characteristic pauses in breathing that are a hallmark of obstructive sleep apnea.

Choice B rationale:

False. Obstructive sleep apnea is not caused by the need for hypnotics or sleep-inducing medications. It is a physiological condition related to airway obstruction during sleep and not a result of poor sleep hygiene or a lack of medication.

Choice C rationale:

False. While it's true that older adults may have changes in their sleep patterns, this doesn't mean they require 10 hours of sleep a day to prevent fatigue. Sleep needs can vary among individuals, and older adults often experience more fragmented sleep and may nap during the day, but the requirement for 10 hours of sleep a day is not a general rule.

Choice D rationale:

False. Older adults may nap more during the day due to changes in their sleep patterns, but it doesn't necessarily mean they need to nap less to sleep better at night. The sleep-wake cycle of older adults may be different from younger individuals, and it's not always necessary for them to reduce daytime napping to improve nighttime sleep.

A. Decreased respirations, rapid heart rate. B. Rapid respirations, rapid heart rate. C. Rapid respirations, slow heart rate. D. Decreased respirations, slow heart rate.

Correct Answer is B

Explanation

Choice A rationale:

Decreased respirations and a rapid heart rate are not indicative of stage 3 of non-rapid eye movement (NREM) sleep. In stage 3, respirations are typically slow and regular, and the heart rate is slower than during wakefulness.

Choice B rationale:

Rapid respirations and a rapid heart rate are indicative of stage 3 of NREM sleep. During this stage, respiration and heart rate are more irregular compared to the earlier stages of sleep. This stage is characterized by increased physiological arousal compared to stages 1 and 2.

Choice C rationale:

Rapid respirations and a slow heart rate do not represent stage 3 of NREM sleep. In this stage, respiration tends to be rapid, and the heart rate, while slower than during wakefulness, is not slow.

Choice D rationale:

Decreased respirations and a slow heart rate are not consistent with stage 3 of NREM sleep. This stage is associated with more active and variable physiological processes, including rapid respirations and a relatively higher heart rate compared to later sleep stages.
