A nurse is providing teaching about home care to a parent of a 3-year-old child who has a fever. Which of the following instructions should the nurse include in the teaching?

A. Place ice packs on the child's armpits and groin: Applying ice packs can cause vasoconstriction and shivering, which may increase the body's core temperature instead of lowering it, making this method inappropriate for fever management in children. B. Apply a light blanket if the child begins to shiver: Shivering generates heat and indicates the child is feeling cold; using a light blanket helps provide comfort and prevents excessive heat loss without causing overheating. C. Take the child's temperature every 10 min after administering acetaminophen: Frequent temperature checks every 10 minutes are unnecessary and may cause distress; checking every 4 to 6 hours is sufficient to monitor response to antipyretics. D. Wake the child every 4 hr during the night to drink 118.3 mL (4 oz) of apple juice: Interrupting a sleeping child without signs of dehydration is not recommended, and sugary drinks like apple juice are not ideal for hydration during illness due to their high sugar content.
