An adult with arthritis has been receiving treatment with naproxen and now reports ongoing stomach pain, increasing weakness, and fatigue. Which laboratory test should the nurse monitor?

Choice A: Increasing oxygen to 6 liters/minute is not an intervention that the nurse should implement, as this can worsen bronchospasm and hypoxia by reducing the hypoxic drive and causing carbon dioxide retention. This is a contraindicated choice.

Choice B: Calling for an Ambu resuscitation bag is not an intervention that the nurse should implement, as this is not indicated for a client who is conscious and breathing spontaneously. This is an overreaction choice.

Choice C: Instructing the client to lie back in bed is not an intervention that the nurse should implement, as this can increase respiratory distress and compromise airway clearance by reducing lung expansion and increasing abdominal pressure. This is another contraindicated choice.

Choice D: Administering a nebulizer treatment is an intervention that the nurse should implement, as this can deliver bronchodilators and anti-inflammatory agents directly to the airways and improve ventilation and oxygenation for this client. Therefore, this is the correct choice.

Choice A: Assigning the UAP to provide care for another client and assume full care of the client is not an action that the nurse should take, as this is unnecessary and inefficient. The UAP can safely assist the client with influenza if they follow proper infection control measures. This is an incorrect choice.

Choice B: Reviewing the need for the UAP to wear a face mask while in close contact with the client is an action that the nurse should take, as this can protect the UAP and others from droplet transmission of influenza. This is a standard precaution that should be reinforced by the nurse. Therefore, this is the correct choice.

Choice C: Instructing the UAP to apply a fitted respirator mask before entering the client's room is not an action that the nurse should take, as this is not indicated for a client with influenza. A respirator mask is required for airborne transmission, not droplet transmission. This is another incorrect choice.

Choice D: Directing the UAP to notify the nurse of any changes in the client's respiratory status is not an action that the nurse should take, as this is a general instruction that does not address the specific issue of infection control. This is another incorrect choice.
