Oxygen therapy
Oxygen therapy ( 22 Questions)
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.
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.
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.
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.
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.
