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.

Answer and Explanation

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.

Correct Answer is D

Explanation

A. Anger is characterized by feelings of hostility and frustration, which may arise as the client acknowledges the reality of their situation.
B. Depression involves feelings of sadness, hopelessness, and despair, often occurring as the client comes to terms with the impending loss or changes associated with their condition.
C. Acceptance involves acknowledging and coming to terms with the reality of the situation without resistance or denial.
D. Denial is a defense mechanism where the client refuses to acknowledge the reality of their situation, such as the need for a lengthy recovery period after open heart surgery. The client's statement reflects denial, as they are minimizing the seriousness of the surgery and its impact on their recovery.

A. Celiac disease B. Lactose intolerance C. Acute renal failure D. Iron-deficiency anemia

Correct Answer is D

Explanation

A. Celiac disease is an autoimmune disorder characterized by intolerance to gluten, a protein found in wheat, barley, and rye. It is not directly related to excessive milk consumption.

B. Lactose intolerance is a condition in which the body is unable to digest lactose, the sugar found in milk and dairy products. Excessive milk consumption could exacerbate symptoms in individuals with lactose intolerance, but it is not the primary concern in this scenario.
C. Acute renal failure is not directly related to excessive milk consumption in an otherwise healthy toddler.
D. Excessive milk consumption can interfere with iron absorption from other foods, leading to iron-deficiency anemia, especially if the child's overall diet is poor or lacks sources of iron.
Therefore, this practice places the toddler at risk for iron-deficiency anemia.
