A nurse at a pediatric clinic is checking the vital signs of a 2-week-old infant. Which of the following findings is outside of the expected reference range?

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.

The nurse should instruct the client to avoid bananas because they are one of the foods that can cause a cross-reaction with latex allergy. This means that people who are allergic to latex may also have an allergic reaction to bananas because they contain similar proteins.

Choice A is wrong because wheat is not a latex cross-reactive food.

Choice B is wrong because strawberries are a low or undetermined cross- reactive food.

Choice C is wrong because peanuts are a low or undetermined cross-reactive food.

Some other foods that the nurse should instruct the client to avoid are avocado, kiwi, chestnut, papaya, and potato. These foods have a high or moderate association with latex cross-reactions. The client should also be careful with other fruits and vegetables that may contain similar proteins to latex.
