A nurse is teaching a newly licensed nurse about a nonrebreather oxygen mask. Which of the following instructions should the nurse include?
Use a nonrebreather mask to deliver low-flow oxygen
A nonrebreather mask should fit snugly over a client's face.
The reservoir bag on a nonrebreather mask should collapse with
A nonrebreather mask dries a client's mucous membranes
The Correct Answer is B
A. A nonrebreather mask is used to deliver high-flow oxygen, not low-flow. It provides the highest concentration of oxygen compared to other types of masks, which is crucial for patients with severe hypoxemia. The high-flow oxygen helps in achieving a higher concentration of oxygen in the blood.
B. It is essential that a nonrebreather mask fits snugly over the client's face to ensure that the patient receives the maximum amount of oxygen and to prevent room air from mixing with the oxygen being delivered. A proper seal is necessary to achieve the desired level of oxygenation and to avoid oxygen leakage.
C. The reservoir bag on a nonrebreather mask should not collapse with each breath. Ideally, the bag should remain partially inflated even during inspiration. If the bag collapses completely, it indicates that the patient is not receiving enough oxygen, and the mask may not be functioning correctly.
D. A nonrebreather mask itself does not cause drying of the mucous membranes. However, high-flow oxygen can sometimes lead to dryness of the mucous membranes if not managed properly. Humidification may be required to prevent dryness, but this is not a direct effect of the mask itself.

Explanation
A. Abdominal pain is not a direct manifestation of respiratory acidosis. However, it may be associated with other conditions or complications but is not a primary indicator of respiratory acidosis.
B. Lethargy or drowsiness is a common symptom of respiratory acidosis. The increased CO₂ levels lead to an acidic environment that can affect brain function, resulting in decreased alertness, confusion, or drowsiness.
C. Numbness or tingling of the fingers is more commonly associated with respiratory alkalosis, which is characterized by a decreased level of CO₂ and increased blood pH. This condition can cause peripheral numbness and tingling due to altered blood pH affecting nerve function.
D. Dry skin is not a direct manifestation of respiratory acidosis. While it might be a sign of dehydration or other systemic issues, it is not specifically linked to respiratory acidosis.
