A nurse is caring for a school-age child who has a new plaster cast on her right arm. Which of the following actions should the nurse take?

A. Firmly push a cotton ball into the ear canal after instilling drops. Firmly pushing a cotton ball into the ear canal is not recommended as it can cause irritation or damage to the ear canal. A loose cotton ball can be placed at the entrance of the ear canal to prevent the drops from leaking out, but it should not be inserted deeply.

B. Pull the child's ear auricle upward and outward just before instilling drops. For a child under 3 years old, the ear auricle should be pulled downward and backward to straighten the ear canal for proper administration of ear drops. Pulling upward and outward is appropriate for older children and adults.

C. Apply clean gloves and clean the outer ear prior to instilling drops. Applying clean gloves and cleaning the outer ear is essential for preventing infection and ensuring that the medication is administered properly. This is a standard procedure to maintain hygiene.

D. Warm the medication container for 10 seconds in a microwave oven prior to installation. Microwaving medication is not recommended as it can overheat and degrade the medication. Warming the drops by holding the container in your hands for a few minutes is safer and helps to avoid the discomfort of cold drops.

A. Diarrhea: Not typically associated with Wilms' tumor, which affects the kidneys and presents primarily with abdominal symptoms.

B. Jaundice: Not a common symptom of Wilms' tumor, which involves the kidneys and usually does not affect liver function.
