Final Answer:
The nurse should question option B, which is providing oxygen via nasal cannula at 4 L/min.
The correct option is B.
Step-by-step explanation:
The rationale for questioning the administration of oxygen via nasal cannula at 4 L/min lies in the potential risk of oxygen toxicity in patients undergoing hemodialysis. Hemodialysis involves the removal of excess fluids and waste products from the blood, and during this process, the patient's oxygen levels can fluctuate. Administering supplemental oxygen without monitoring oxygen saturation levels may lead to hyperoxia, which can be harmful.
Hemodialysis can affect the patient's respiratory status, and the need for supplemental oxygen should be based on individual oxygen saturation levels. The nurse should assess the patient's respiratory status, monitor oxygen saturation levels, and administer oxygen judiciously based on the patient's specific needs. Unnecessary oxygen supplementation can lead to complications, and a tailored approach to oxygen therapy is essential.
In summary, questioning the administration of oxygen via nasal cannula at 4 L/min is crucial to ensure patient safety. The nurse should prioritize individualized care, considering the patient's respiratory status and oxygen saturation levels to avoid potential complications associated with inappropriate oxygen supplementation during hemodialysis.
The correct option is B.
