A patient is undergoing oxygen therapy through a nasal cannula.If the patient inquires about the reason for having oxygen tubing in their nose, what explanation about the cannula should the nurse provide?
It allows you to remove it for a while when it gets uncomfortable.
It delivers the low concentration of oxygen you need.
It delivers a specific concentration of oxygen constantly.
It delivers the highest concentration of oxygen possible.
The Correct Answer is B
Choice A rationale
While it’s true that a nasal cannula allows the patient to remove it for a while when it gets uncomfortable, this is not the primary reason for using a nasal cannula. The main purpose of a nasal cannula is to deliver oxygen.
Choice B rationale
A nasal cannula delivers the low concentration of oxygen that the patient needs. It is designed to provide a specific amount of oxygen, and the flow rate can be adjusted as needed.
Choice C rationale
While a nasal cannula does deliver a specific concentration of oxygen, it does not do so constantly. The amount of oxygen delivered can vary depending on the patient’s breathing rate and depth.
Choice D rationale
A nasal cannula does not deliver the highest concentration of oxygen possible. Other devices, such as non-rebreather masks, can deliver higher concentrations of oxygen.

Correct Answer is A
Explanation
Choice A rationale
The nurse should prioritize the safety of the patient. If a patient is frequently attempting to remove his feeding tube, it could lead to complications such as infection or injury. Therefore, the nurse might need to consider using a restraint as a last resort. However, it’s important to note that restraints should only be used when all other alternatives have been explored and failed. These alternatives include having staff or a family member sit with the patient, using distraction or de-escalation strategies, offering reassurance, using bed or chair alarms, and administering certain medications.
Choice B rationale
Covering the catheter so the patient cannot see it might not be effective if the patient is aware of its presence and is determined to remove it. This approach does not address the underlying issue and may not prevent the patient from attempting to remove the feeding tube.
Choice C rationale
Providing more stimulation in the patient’s environment might be helpful in some cases, but it may not prevent the patient from attempting to remove the feeding tube. The effectiveness of this approach would depend on the specific circumstances and the patient’s condition.
Choice D rationale
Waiting until tonight to see if the patient continues this behavior could potentially put the patient at risk. If the patient is frequently attempting to remove the feeding tube, immediate action may be necessary to ensure the patient’s safety.
Correct Answer is B
Explanation
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.
