A nurse is reinforcing dietary teaching with the guardians of a toddler. Which of the following snack foods should the nurse recommend?

Answer: B. Reposition the probe every 2 hours.

Rationale:

• A. Warm the skin prior to probe placement:While cold fingers can lead to inaccurate readings,warming the skin is not an essential step and is not routinely recommended in clinical practice.
• B. Reposition the probe every 2 hours:This iscorrect.Continuous pressure from the probe in one spot can cause skin breakdown and pressure injuries.Repositioning the probe every 2 hours helps to prevent this and ensure accurate readings.
• C. Tape the wire to the palm of the hand:This is incorrect.The pulse oximeter probe should be placed on a vascular site,such as a fingertip or earlobe.Taping the wire to the palm would not provide accurate readings.
• D. Apply the sensor to the index fingernail:This is incorrect.The fingernail does not have sufficient blood flow for accurate pulse oximetry readings.The probe should be placed on the fleshy pad of the fingertip.

Therefore, the most important action for the nurse to take is to reposition the probe every 2 hours to prevent skin breakdown and ensure accurate readings.

Additional Points:

• The nurse should also choose a clean and dry site for probe placement.
• The probe should be snug but not too tight.
• The nurse should monitor the child for signs of skin breakdown,such as redness,swelling,or pain.
• If the child is restless or active,the nurse may need to secure the probe with additional tape or a special wrap.

Choice A rationale:
Insulin administration is not appropriate in this situation. The child's symptoms (slurred speech, diaphoresis, low blood glucose reading) indicate hypoglycemia, which is a state of low blood sugar. Administering insulin, which lowers blood glucose further, would exacerbate the hypoglycemia and could lead to more severe symptoms or even unconsciousness.
Choice B rationale:
Metformin is not indicated in this scenario. Metformin is an oral medication used to treat type 2 diabetes, not type 1 diabetes mellitus. The child in the scenario has type 1 diabetes, which is characterized by an absolute deficiency of insulin production.
Choice C rationale:
Offering a 6 oz diet soft drink is not the appropriate intervention for hypoglycemia. Diet soft drinks do not contain significant amounts of sugar, which is needed to rapidly raise the child's blood glucose levels. In cases of hypoglycemia, a source of quickly absorbable sugar, such as a regular soft drink or fruit juice, is recommended.
Choice D rationale:
Administering a 6 oz regular soft drink is the appropriate intervention in this situation. The child is experiencing hypoglycemia, which means their blood glucose levels are dangerously low. Regular soft drinks contain rapidly absorbable sugar that can quickly raise the child's blood glucose levels, alleviating the symptoms of hypoglycemia. The child's symptoms, including slurred speech and diaphoresis, are indicative of a need for immediate intervention to raise blood sugar levels.
