A nurse is caring for a client who is receiving oxygen via nasal cannula at 4 L/min. Which of the following actions should the nurse take?
Avoid the use of humidifiers.
Position the cannula prongs curving upward in the nose.
Clean the cannula prongs daily.
Keep the oxygen tubing off the floor.
The Correct Answer is C
Clean the cannula prongs daily.
This is because the nasal cannula can become contaminated with bacteria and mucus, which can cause infection and irritation of the nasal mucosa. Cleaning the cannula prongs daily with soap and water can prevent these complications.
Choice A is wrong because humidifiers can help moisten the dry oxygen and prevent nasal dryness and bleeding. Humidifiers should be used for oxygen flow rates higher than 4 L/min.
Choice B is wrong because the cannula prongs should be positioned curving downward in the nose, not upward. This allows for better alignment with the natural direction of airflow and reduces the risk of dislodgement.
Choice D is wrong because keeping the oxygen tubing off the floor is not a specific action for nasal cannula use. It is a general safety measure to prevent tripping and contamination of the tubing.

It can be a sign of dysphagia or throat irritation.
Choice D is wrong because bleeding gums is not an adverse effect of digoxin. It can be a sign of gingivitis or coagulation disorder.
Other adverse effects of digoxin include nausea, vomiting, diarrhea, lower stomach pain, dizziness, drowsiness, headache, weakness, confusion, depression, anxiety, hallucinations, expressed fear of impending death, rash, weight loss, loss of appetite, and various cardiac arrhythmias.
