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.

B. Guarding the abdominal incision is an objective sign of pain and discomfort but does not reflect the client's perception of pain.
C. Facial grimacing is an objective sign of pain but may not always correlate with the client's perception of pain.

Correct Answer is D
Explanation
A. Incorrect. Bupropion is not typically used as a first-line treatment for bulimia nervosa. Additionally, administering it before meals is not a standard practice for managing bulimia nervosa.
B. Incorrect. Allowing the client unrestricted access to food throughout the day may exacerbate binge-eating behaviors associated with bulimia nervosa. Structured meal plans are typically recommended instead.
C. Incorrect. While monitoring weight is important in the management of bulimia nervosa, weighing the client once weekly may not provide adequate monitoring, as fluctuations in weight can occur more frequently.
D. Correct. Observing the client for a period after meals helps to prevent purging behaviors, such as self-induced vomiting or misuse of laxatives, which are common in bulimia nervosa. This intervention allows for immediate intervention if purging behaviors are observed and can help ensure the client's safety.
