A nurse is caring for a patient with pneumonia who has been on oxygen therapy for several days.
Which of the following symptoms should the nurse recognize as a potential adverse effect of oxygen therapy?

Choice A rationale
Using a humidifier beside the bed at night may not necessarily decrease the number of apneic episodes in a client with obstructive sleep apnea. While a humidifier can help moisten the airways and may provide some relief from symptoms such as dry mouth or throat, it does not address the underlying issue of airway obstruction.
Choice B rationale
Losing weight can indeed help decrease the number of apneic episodes in a client with obstructive sleep apnea. Obesity is a major risk factor for sleep apnea, as excess fat tissue can thicken the wall of the windpipe, making it narrower and making it harder to keep open.
Therefore, losing weight can help reduce this fat and widen the airway, leading to fewer apneic episodes.
Choice C rationale
Taking a sleeping pill at night may actually worsen obstructive sleep apnea. While it might help the client fall asleep, it can also relax the muscles of the throat, which can make the airway more likely to collapse during sleep, leading to more apneic episodes.

Choice D rationale
Drinking a glass of red wine before bedtime is not recommended for a client with obstructive sleep apnea. Alcohol can relax the muscles in the throat and can disrupt the normal sleep cycle, both of which can lead to more apneic episodes.

Choice A rationale
Requesting a prescription for the insertion of an indwelling urinary catheter is not the best option to prevent skin breakdown in a client with urinary incontinence. Catheters can increase the risk of urinary tract infections and should be used as a last resort.
Choice B rationale

Applying a moisture barrier ointment to the skin can help protect the skin from the damaging effects of urine. This can help prevent skin breakdown and is a common practice in the care of clients with urinary incontinence.
Choice C rationale
Cleaning the skin and perineum with hot water after each episode of incontinence is not recommended. Hot water can dry out the skin and cause irritation. It’s better to use warm water and a gentle cleanser.
Choice D rationale
Checking the client’s skin every 8 hours for signs of breakdown is important, but it’s not the only action the nurse should take. The nurse should also take proactive measures to protect the skin, such as applying a moisture barrier ointment.
