A nurse is preparing to discharge a client who requires home oxygen. The equipment company has not yet delivered the oxygen tank. Which of the following actions should the nurse take?

The correct answer is D. The nurse should notify the provider about the delayed oxygen tank delivery to ensure timely resolution. This is crucial for the client's safety and well-being. Instructing the family to contact the insurance provider (A) may cause confusion and delay. Sending an oxygen tank from the facility (B) could lead to unauthorized use and potential safety hazards. Contacting social services (C) may not be necessary if the issue can be resolved directly. Therefore, option D is the most appropriate course of action in this situation.
