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 A
Explanation
A. Frequent swallowing after a tonsillectomy may indicate postoperative bleeding. The nurse should check the back of the throat with a pen light to assess for signs of hemorrhage.
B. While obtaining vital signs is important, it does not directly address the concern of potential bleeding.
C. Administering analgesia is appropriate for pain management but does not address the priority concern of bleeding.
D. Offering water could potentially worsen bleeding if it is occurring and should not be the first action.
Correct Answer is B
Explanation
This is because the client has hypothyroidism, which means their thyroid gland does not produce enough thyroid hormone. Levothyroxine is a synthetic form of thyroid hormone that can replace the missing hormone and normalize the TSH level. The client’s TSH level is 8.9 mIU/L, which is above the normal range of 0.4 to 4.0 mIU/L. This indicates that the client’s current dosage of levothyroxine is insufficient and needs to be increased.
Choice A is wrong because thyroid ablation therapy is a treatment for hyperthyroidism, not hypothyroidism.
Thyroid ablation therapy involves destroying part or all of the thyroid gland with radioactive iodine or surgery, which reduces the production of thyroid hormone.
This would worsen the client’s condition and symptoms.
Choice C is wrong because lovastatin is a statin drug that lowers cholesterol levels. Hypothyroidism can cause high cholesterol levels, but this is usually corrected by levothyroxine therapy. Replacing lovastatin with cholestyramine, a bile acid sequestrant that also lowers cholesterol levels, would not address the underlying cause of hypothyroidism and would not improve the client’s TSH level.
Choice D is wrong because restricting the intake of iodized salt would not help the client with hypothyroidism. Iodine is an essential element for the synthesis of thyroid hormone, but most people in developed countries get enough iodine from their diet.
Hypothyroidism is usually caused by autoimmune disease, not iodine deficiency.
