Final answer:
One should not turn off the oxygen at mealtimes while performing safety precautions for a client receiving oxygen through a nasal tube. Other safety measures include ensuring no kinks in the tube, providing oral hygiene, and prohibiting smoking in the room.
Step-by-step explanation:
The correct answer is B) turn off the oxygen at mealtimes. When caring for a client receiving oxygen therapy through a nasal tube, there are several safety precautions that must be followed. However, among the options given, turning off the oxygen at meal times is not one of them. Ensuring that there are no kinks in the tubing (A), offering oral hygiene as directed (C), and posting a no smoking sign in the client's room (D), are all appropriate safety measures. Additionally, continuous oxygen supply is critical, and thus it should not be turned off at mealtimes unless specifically instructed by a medical professional.
Other safety notes regarding oxygen therapy include making sure that the pulse oximeter is functioning to monitor the client's oxygen saturation, evaluating the risk of aspiration, and being aware of the client's allergies. These precautions ensure the client receives a consistent flow of oxygen, which is crucial for maintaining healthy oxygen levels in the blood. The oxygen is warmed and humidified by the nasal passages, which helps ward off infection, decrease sensitivity during breathing, and prevent damage to the lungs.
