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.

Correct Answer is C
Explanation
Verapamil is a calcium channel blocker that can lower the heart rate and blood pressure. A normal pulse rate for adults is between 60 and 100 beats per minute. A pulse rate of 48/min is too low and indicates bradycardia, which can cause dizziness, fainting, or cardiac arrest. Verapamil should not be given to patients with bradycardia or heart block.
Choice A is wrong because blood pressure 170/82 mm Hg is high and verapamil can help lower it. A normal blood pressure for adults is less than 120/80 mm Hg.
Choice B is wrong because respiratory rate 18/min is normal and verapamil does not affect it. A normal respiratory rate for adults is between 12 and 20 breaths per minute.
Choice D is wrong because potassium 4 mEq/L is normal and verapamil does not affect it. A normal potassium level for adults is between 3.5 and 5.0 mEq/L.
Correct Answer is A
Explanation
Encourage the client to help care for their surgical incision. This can help the client accept the body image change and promote healing.
Choice B is wrong because suggesting that the client decide about reconstruction as soon as possible can pressure the client and interfere with their coping process.
Choice C is wrong because postponing referrals to support services until the client requests them can delay the client’s emotional recovery and increase their isolation.
Choice D is wrong because avoiding talking to the client about the surgery can indicate that the nurse is uncomfortable with the topic and discourage the client from expressing their feelings.
