Multiple Choice

Which nursing intervention is indicated when a patient is using a non-rebreather mask?

Ensure the reservoir bag is inflated before placing the mask on the patient.

Remove the mask every hour to prevent skin breakdown.

Switch to a nasal cannula if the patient feels claustrophobic.

Set the oxygen flow rate to 2 liters per minute.

Verified step by step guidance

Understand the purpose of a non-rebreather mask: It is used to deliver high concentrations of oxygen to patients in respiratory distress.

Recognize the importance of the reservoir bag: The bag must be inflated to ensure the patient receives the correct oxygen concentration.

Identify the correct oxygen flow rate: A non-rebreather mask typically requires a flow rate of 10-15 liters per minute to keep the bag inflated.

Consider patient comfort and safety: While ensuring the mask is properly used, also monitor the patient for any signs of discomfort or skin breakdown.

Evaluate alternative options: If the patient feels claustrophobic, consider switching to a nasal cannula, but only if it meets the patient's oxygen needs.
