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.

Correct Answer is A
Explanation
A. Rinsing the client's mouth helps to remove oral contaminants, ensuring that the sputum specimen is representative of the respiratory secretions.
B. Obtaining the specimen in the evening is not a specific requirement; the best time to collect the specimen is when the client has the most productive cough.
C. Saving the sputum specimen in a clean container is essential to prevent contamination. However, a sterile container is usually required.
D. Collecting the sputum specimen after a meal might induce coughing but can also contaminate the specimen with food particles.
Correct Answer is ["675"]
Explanation
1 kilogram is approximately 2.2 pounds.
The client weighs 198 pounds, which is equivalent to about 90 kilograms (198 lb / 2.2).
Next, multiply the client's weight in kilograms by the dosage prescribed, which is 15 mg/kg/day. This results in a total daily dosage of 1350 mg (90 kg * 15 mg/kg). Since the medication is to be administered every 12 hours, divide the total daily dosage by 2 to get the amount for each dose. Therefore, the nurse should administer 675 mg every 12 hours.
