A home care client receives oxygen by nonrebreather (NRB) mask. Which does the nurse include when teaching the caregiver about the oxygen delivery system?

Question

1. Keep the plastic bag at the end of the mask inflated continually.
2. Adjust the oxygen flow rate with the valve in front of the mask.
3. Offer fluids frequently and apply moisturizer to prevent dry skin.
4. Remove the elastic head strap to prevent skin breakdown at ears.

1. To prevent inhalation of carbon dioxide, the nurse instructs the caregiver to main-tain an inflated bag at the end of the mask because it serves as an oxygen reservoir for the client. If the bag deflates, the client is at risk to inhale excessive levels of carbon dioxide.
2. The nurse regulates the oxygen flow rate by adjusting the flow meter on the oxy-gen source; an NRB mask does not have a mixing valve.
3. A NRB mask does not dehydrate the client.
4. The NRB mask requires a tight seal for effective therapy, making it uncomfortable and difficult to maintain.
