A nurse is caring for a client who is using a non-rebreather mask for oxygen delivery. The nurse should identify which of the following as an indication that the equipment is functioning properly?
Air is heard escaping from around the mask.
The flow control meter dial is at the correct setting.
The attached reservoir bag is inflated.
The exhalation ports are covered during inspiration and expiration.
The Correct Answer is C
A. Air escaping from around the mask indicates a poor mask seal, which would lead to inadequate oxygen delivery and is not an indication of proper equipment function.
B. The flow control meter dial being at the correct setting ensures the appropriate flow rate of oxygen but does not directly indicate the functionality of the mask and reservoir system. C. The attached reservoir bag should be inflated with oxygen when the mask is properly connected and functioning, indicating the delivery of high-concentration oxygen to the client.
D. The non-rebreather mask should not have exhalation ports that are covered during inspiration and expiration; rather, it should allow exhaled air to escape to prevent carbon dioxide buildup within the mask.

C. Having a bowel movement every other day may vary depending on the newborn's age and feeding patterns and is not necessarily an indicator of effective breastfeeding.
