A nurse is planning to administer immunizations to a 2-month-old infant. Which of the following actions should the nurse take to decrease the infant's pain?

Choice A reason: Applying tepid water to the old dressings can help with their removal and may reduce discomfort, but it does not address the greatest risk to the client, which is infection.

Choice B reason: Checking the wound sites for manifestations of infection is crucial as burn injuries compromise the skin's protective barrier, making the client highly susceptible to infections. Infections can lead to further complications and delay healing.

Choice C reason: Performing passive range-of-motion exercises is important for maintaining joint mobility and preventing contractures in burn patients, but it is not the primary intervention for addressing the greatest risk of infection.

Choice D reason: Adjusting the room temperature to 33°C (91.4°F) can create a more comfortable environment for the burn patient and prevent hypothermia, but it is not directly related to the prevention of infection, which is the greatest risk.

Choice A reason: Asking the parent to leave the room during the injections is not recommended as the presence of a parent can provide comfort to the infant, which may help in reducing pain and anxiety.

Choice B reason: Administering the injections while the infant is breastfeeding is an effective method to decrease pain. Breastfeeding provides comfort and distraction, and the natural sugars in breast milk can have a mild analgesic effect.

Choice C reason: Applying a warm pack to the injection site prior to administration is not a standard practice for reducing pain from immunizations. Instead, using a cold compress after the injection can help to reduce swelling and discomfort.

Choice D reason: Administering injections in the deltoid muscle is not appropriate for a 2-month-old infant due to the underdeveloped muscle mass. The anterolateral thigh is the recommended site for immunizations in infants.
