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 D
Explanation
. Objectively examining one's own bias, beliefs, values, and practices is the best way for nurses to develop an awareness of their own culture and bias. It is important for nurses to recognize that they have their own set of beliefs and values that may influence their perceptions and interactions with patients from different cultural backgrounds. Through selfreflection and self-awareness, nurses can identify their own biases and work towards addressing them. This will help nurses provide culturally competent care and build trusting relationships with their patients. Choices A and B are incorrect because they imply that personal biases cannot be changed, which is not true. Choice C may provide some insight into how other nurses practice cultural diversity, but it does not address the nurse's own personal biases and cultural background.
Correct Answer is A
Explanation
The correct answer is choice A. Lower the patient back to the side of the bed, pivot her back into the bed, and assess the patient's vital signs. When a patient reports feeling faint while attempting to stand, it is important to take immediate action to prevent a fall and ensure patient safety. Lowering the patient back to the bed will help prevent injury in case of a fall. Then, the nurse should pivot the patient back into the bed slowly and safely. Once the patient is lying down, assess the vital signs, particularly the blood pressure and heart rate, to ensure that the patient is stable. This information can help the nurse determine if the patient is experiencing postural hypotension or other complications from surgery. After assessing the vital signs, the nurse can report the findings to the healthcare provider and implement appropriate interventions to help prevent future episodes of fainting.
