Which statement best describes the proper initiation of oxygen therapy?

• A. Oxygen can be started without a prescription in emergencies.
• B. Oxygen therapy does not require monitoring after initiation.
• C. Oxygen can be started by any staff member without physician input.
• D. Oxygen therapy must be prescribed and monitored.

Answer: (D)

Oxygen therapy is a medication and must be started only with an order and then continuously monitored. This ensures the right amount is given for the patient’s condition, with a specified target saturation, delivery method, and flow. Monitoring after initiation is essential because the patient’s needs can change, and there are risks like oxygen toxicity or CO2 retention in certain patients. In emergencies, you may begin oxygen under a protocol, but it still requires a formal prescription and ongoing assessment to adjust therapy as needed. That combination—prescription and monitoring—best describes proper initiation.
