Question 5 of 5
What action does the nurse perform to follow safe technique when using a portable oxygen cylinder?
Correct Answer: A
Rationale: The cylinder must always be checked before use to ensure that enough oxygen is available for the patient. It is unsafe to use a cylinder that reads 500 psi or less because not enough oxygen remains for a patient transfer. A cylinder that is not secured properly may result in injury to the patient. Oxygen flow is discontinued by turning the valve clockwise until it is tight.
