A nurse is caring for a patient who is receiving oxygen therapy via partial rebreather mask at 10 L/min. The nurse should instruct the patient to do which of the following to ensure effective oxygen delivery?
Keep the reservoir bag fully inflated at all times.
Breathe through the mouth and exhale through the nose.
Adjust the elastic strap to fit snugly around the face.
Remove the mask every 15 minutes to check the skin.
The Correct Answer is A
Keep the reservoir bag fully inflated at all times.
Choice A rationale:
In a partial rebreather mask, the reservoir bag should be kept fully inflated at all times to ensure the delivery of the highest possible oxygen concentration during inspiration. The bag collects oxygen during expiration, and the one-way valve prevents the exhaled gases from entering the bag. This way, the patient can inhale a mixture of oxygen from the reservoir and fresh oxygen flow.
Choice B rationale:
Breathing through the mouth and exhaling through the nose is not a necessary instruction for a patient using a partial rebreather mask. It doesn't directly impact the effectiveness of oxygen delivery.
Choice C rationale:
Adjusting the elastic strap to fit snugly around the face is not specific to ensuring effective oxygen delivery. It is a general guideline for mask fitting but doesn't directly affect oxygen administration.
Choice D rationale:
Removing the mask every 15 minutes to check the skin is not necessary and can disrupt the delivery of oxygen therapy. It's essential to maintain a consistent oxygen supply to the patient's lungs, and removing the mask frequently can compromise that. Checking the skin can be done periodically without removing the mask completely.

Correct Answer is A
Explanation
A humidifier.
Choice A rationale:
A humidifier is necessary to prevent complications in a patient receiving oxygen therapy via a tracheostomy collar. Oxygen delivered through a tracheostomy can dry out the airways and cause discomfort and potential complications. Adding humidity helps maintain airway moisture and prevents drying of the mucous membranes, reducing the risk of mucus plugs and irritation.
Choice B rationale:
A water seal is not necessary for a patient receiving oxygen therapy via a tracheostomy collar. Water seals are used in chest drainage systems to prevent air from entering the pleural space, but they are not relevant in this scenario.
Choice C rationale:
A suction catheter is used to clear secretions from the airway but is not directly related to preventing complications with oxygen therapy via a tracheostomy collar.
Choice D rationale:
A chest tube is not needed for a patient receiving oxygen therapy via a tracheostomy collar. Chest tubes are inserted to drain fluid or air from the pleural space, which is not applicable to this situation.
Correct Answer is ["A","C","E"]
Explanation
The correct answers are choices A, C, and E.
Choice A rationale:
A Venturi mask is designed to deliver a precise concentration of oxygen and is often used in COPD, where it is important not to over-oxygenate the patient. It allows for the adjustment of oxygen concentration by changing the color-coded entrainment adapters.
Choice B rationale:
A non-rebreather mask is not typically used for clients who require a precise concentration of oxygen because it is designed to deliver high concentrations of oxygen, but without a way to precisely control the amount.
Choice C rationale:
An aerosol mask can be used with a nebulizer system to deliver specific concentrations of oxygen along with medication, which is beneficial for COPD patients who may need bronchodilators or steroids in addition to oxygen therapy.
Choice D rationale:
A simple face mask is not suitable for delivering a precise concentration of oxygen as it does not allow for the fine control needed for COPD patients. It is generally used for short-term oxygen therapy and for patients who require a moderate amount of oxygen.
Choice E rationale:
A tracheostomy collar can provide a specific concentration of oxygen when used with a tracheostomized patient and is suitable for long-term use in COPD patients who have a tracheostomy.
In summary, for a client with COPD who requires a precise concentration of oxygen, the Venturi mask, aerosol mask, and tracheostomy collar are appropriate choices as they allow for the delivery of a specific and controlled amount of oxygen.
