A nurse is preparing to administer immunizations to a 3-month-old infant. Which of the following is an appropriate action for the nurse to take to deliver atraumatic care?

A. Use a 20-gauge needle for the injections: A 20-gauge needle is too large for an infant and can cause unnecessary pain and tissue trauma. For a 3-month-old, a smaller gauge needle, typically 22–25 gauge, is recommended to minimize discomfort and tissue damage. B. Provide a pacifier coated with an oral sucrose solution prior to the injections: Administering a pacifier with sucrose before immunizations provides a sweet taste that has analgesic effects for infants, reducing procedural pain and distress. This is a noninvasive strategy that aligns with the principles of atraumatic care for infants. C. Apply eutectic mixture of local anesthetics (EMLA) cream immediately before the injections: EMLA cream requires 30–60 minutes to achieve adequate numbing and applying it immediately before injections will not provide pain relief. Proper timing is necessary to use this method effectively for atraumatic care. D. Inject the immunizations into the deltoid muscle: The deltoid muscle in a 3-month-old is underdeveloped and too small for safe intramuscular injections. The recommended site for infants is the vastus lateralis muscle, which provides adequate muscle mass and reduces the risk of injury.
