prevent drying.
B. Ensure the oxygen tank is secured in an upright
position.
C. Place a "No Smoking" sign on the client's door.
D. Check the oxygen flow rate every 2 hours.

essential to prevent fires. While securing the tank
and monitoring flow are important, preventing
ignition sources is the most critical safety measure.

oxygen as they are flammable.

recent illness must be excluded to protect the
immunocompromised client.
