A patient hospitalized with chronic obstructive pulmonary disease (COPD) is being discharged home on oxygen therapy. Which instruction should the nurse include in the discharge teaching?
Store the oxygen tanks near sources of heat to prevent them from freezing.
Use the oxygen therapy only during periods of activity or exertion.
Adjust the oxygen flow rate to the highest level possible to improve breathing.
Use the oxygen therapy continuously, even during sleep.
The Correct Answer is D
A. Storing oxygen tanks near sources of heat is dangerous. Oxygen should be stored in a cool, dry place away from heat sources and flammable materials to prevent the risk of fire or explosion.
B. Oxygen therapy should not be limited to periods of activity or exertion. For patients with COPD, continuous oxygen therapy is often necessary to maintain adequate oxygen saturation levels, even during sleep.
C. Adjusting the oxygen flow rate to the highest level can be harmful, especially in patients with COPD, as it may suppress their hypoxic drive to breathe. The flow rate should be prescribed and adjusted by the healthcare provider.
D. Continuous use of oxygen therapy, even during sleep, is essential for maintaining adequate oxygen saturation levels in patients with COPD. This helps prevent hypoxemia and ensures the patient receives the necessary oxygen support.

Explanation
- Convert liters to milliliters: 1 liter = 1000 mL
- Calculate total infusion time in minutes: 8 hours 60 minutes/hour = 480 minutes
- Apply the formula:
- (Total volume in mL Drop factor) / Total infusion time in minutes = Drops/minute
- (1000 mL 15 gtts/mL) / 480 minutes = 31.25 gtts/minute
- Round to the nearest whole number: 31 gtts/minute
Correct Answer is D
Explanation
A. Tidal fluctuation in the water seal chamber is an expected finding in a chest tube drainage system. It indicates that the pleural space is still connected to the atmosphere, and the lungs are expanding and contracting normally.
B. Continuous bubbling in the suction control chamber is normal when the chest tube is connected to suction. This shows that the suction system is functioning properly.
C. Chest tube eyelets not being visible is expected when the chest tube is properly positioned inside the pleural space. This finding does not require immediate notification.
D. Development of subcutaneous emphysema (air trapped under the skin) may indicate an air leak or improper chest tube placement. This finding requires immediate notification of the provider to address the underlying cause and prevent complications.
