A nurse is caring for a client who complains about sleep apnea.
Which delivery device would the nurse expect to use to administer oxygen to this client while sleeping?
CPAP mask.
Nasal cannula.
Non-rebreather mask.
Simple face mask.
The Correct Answer is A
Choice A rationale
A CPAP (Continuous Positive Airway Pressure) mask delivers a constant stream of pressurized air to keep the airway open during sleep, which is the primary treatment for sleep apnea. Sleep apnea is characterized by repeated pauses in breathing due to airway obstruction, and CPAP effectively prevents these episodes.
Choice B rationale
A nasal cannula delivers low-flow oxygen through two prongs inserted into the nostrils. While it can provide supplemental oxygen, it does not address the underlying airway obstruction that occurs in sleep apnea. Therefore, it is not the expected delivery device for this condition. Normal flow rate is 1 to 6 liters per minute, providing a fraction of inspired oxygen (FiO2) of 24% to 44%.
Choice C rationale
A non-rebreather mask delivers a high concentration of oxygen (60% to 90%) and is typically used for patients with acute respiratory distress. It is not the appropriate device for managing the chronic condition of sleep apnea, which primarily requires airway support rather than high oxygen levels.
Choice D rationale
A simple face mask delivers a moderate concentration of oxygen (40% to 60%) and requires a flow rate of 5 to 8 liters per minute. While it provides more oxygen than a nasal cannula, it does not address the airway obstruction inherent in sleep apnea and is therefore not the expected device for this condition.

Correct Answer is B
Explanation
Choice A rationale
Negligence is the failure to exercise the care that a reasonably prudent person would exercise in similar circumstances. While administering the wrong medication is a breach of duty, legal charges of negligence might not fully capture the severity of a serious untoward reaction resulting from a medication error by a professional.
Choice B rationale
Malpractice is a specific type of negligence committed by a professional, such as a nurse, in the performance of their professional duties. Administering the wrong medication, leading to a serious adverse reaction, falls under the scope of professional nursing practice and can be considered a breach of the professional standard of care, thus potentially leading to charges of malpractice.
Choice C rationale
Assault is an intentional act that creates a reasonable apprehension of immediate harmful or offensive contact. Administering medication, even the wrong one, is usually not intended to cause apprehension of harm in the way assault is legally defined.
Choice D rationale
Battery is the intentional touching of another person without consent. While administering the wrong medication involves touching without consent, the more appropriate legal charge in a professional healthcare setting where harm results from a breach of duty is typically malpractice. .
Correct Answer is D
Explanation
Choice A rationale
While clarifying values is important in end-of-life care, the immediate need is to respect the client's current wishes and provide space for processing his emotions. Forcing a values clarification at this moment might add pressure.
Choice B rationale
Educating the client on death and dying concepts might be helpful at some point, but it doesn't directly address his immediate emotional need to protect his family from sadness. His focus is on their well-being, not his understanding of the dying process.
Choice C rationale
Arranging a meeting without the client's consent or readiness disregards his autonomy and stated wishes. This could increase his distress and violate his right to make decisions about his interactions.
Choice D rationale
Providing time for quiet reflection acknowledges the client's emotional state and respects his need to process his feelings privately. This allows him to cope with his impending death in a way that feels most comfortable and protective of his family, fostering autonomy and dignity.
