Final answer:
To ensure safe administration of oxygen therapy, the nurse should ensure the prescribed and monitored oxygen flow rate.
Step-by-step explanation:
To ensure safe administration of oxygen therapy, the nurse should:
- Administer oxygen using an oxygen mask or nasal cannula, not a plastic cup (option a is incorrect).
- Avoid using petroleum-based products on the client's face as they can be flammable and pose a risk (option b is incorrect).
- Secure the oxygen tubing behind the client's ears and under the chin, not under the client's arms, to ensure proper placement and prevent dislodgment (option c is incorrect).
- Ensure the oxygen flow rate is prescribed and monitored to maintain the appropriate level for the client's needs (option d is correct).
