A nurse is preparing to administer a vaccine to a toddler. Which of the following actions should the nurse plan to take?

A. A hot spot on the cast may indicate localized infection. When the skin underneath the cast becomes infected, it can lead to localized warmth, tenderness, and redness. It is important to promptly assess and address the situation, as infections can progress quickly in these circumstances.

B. General edema of the toes is a common response to immobilization and injury, but it does not specifically indicate infection. It is more likely related to inflammation or impaired circulation from the cast.

C. Pruritus (itching) under the cast can occur due to the skin's reaction to the cast material, dryness, or moisture accumulation, but it is not necessarily an indication of infection.

D. Pain at the fracture site is common and expected as the fracture heals, but it alone is not an indication of infection unless associated with other symptoms like fever, warmth, or drainage.

A. Infants with heart failure may experience fatigue during feeding, so smaller, more frequent feedings are recommended to prevent exhaustion and ensure adequate nutrition. Feedings every 3 hours are typically recommended to maintain a steady intake without overexertion.

B. Diluting formula to half strength is not recommended for an infant with heart failure, as it can lead to malnutrition and insufficient caloric intake. The formula should be provided at normal strength.

C. Placing the infant in a lateral position during feeding could be unsafe, as it may increase the risk of aspiration. The infant should generally be fed in an upright or semi-upright position to reduce aspiration risk and promote optimal digestion.

D. Bolus gavage feedings are typically used for infants who are unable to feed orally due to medical conditions, but for a child with heart failure who is feeding orally, more frequent and smaller feedings would be preferable.
