A nurse is caring for a patient receiving oxygen from a humidification bottle. Which observation requires correction?
Correct answer: C. The water level is above the maximum line
- A. The bottle contains sterile water up to the marked level
- B. The tubing is connected firmly to the oxygen outlet
- C. The water level is above the maximum line
- D. The patient has less dryness in the nose and throat
Explanation
Overfilling the humidifier can allow water to enter the tubing and interfere with oxygen delivery or reach the patient. The bottle should contain the recommended sterile water level, with connections secure and tubing positioned to avoid drainage toward the patient.
