A nurse is caring for a patient who has a tracheostomy and is receiving oxygen therapy via tracheostomy collar at 40% FiO2. The nurse should ensure that which of the following is in place to prevent complications?
A humidifier.
A water seal.
A suction catheter.
A chest tube.
The Correct Answer is A
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
Explanation
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
Choice A rationale:
At a flow rate of 4 L/min, oxygen therapy through a nasal cannula can increase the risk of oxygen toxicity, especially if used for prolonged periods. Oxygen toxicity can cause damage to the lungs and other organs.
Choice B rationale:
Carbon dioxide retention is not a common complication at this flow rate. It may occur in patients with severe chronic obstructive pulmonary disease (COPD) at higher oxygen flow rates.
Choice C rationale:
Nasal dryness is a common but relatively minor complication of oxygen therapy via nasal cannula. It can cause discomfort but is not a severe concern.
Choice D rationale:
Fire hazard is not directly related to the use of a nasal cannula but rather to the use of oxygen in the presence of flammable materials or near open flames. It is a concern for all oxygen delivery devices, not specific to nasal cannulas.
