An alarm beeps notifying you that one of your patient's oxygen saturation is reading $89 \%$. You arrive to the patient's room, and see the patient comfortably resting in bed watching television. The patient is already on $2 \mathrm{~L}$ of oxygen via nasal cannula. The patient is admitted for COPD exacerbation. Your next nursing action would be:
- A. Continue to monitor the patient
- B. Increase the patient's oxygen level to $3 \mathrm{~L}$
- C. Notify the doctor for further orders
- D. Turn off the alarm settings
Correct Answer: A
Rationale: In COPD, oxygen saturation of 88-92% is acceptable to avoid suppressing the hypoxic drive. Since the patient is comfortable, continue monitoring . Increasing oxygen or notifying the doctor is unnecessary unless symptoms worsen.
