Final answer:
For a 4-month-old receiving immunizations, providing a sucrose solution on the pacifier can help reduce pain and discomfort. Aspirin is not recommended for infants, and the Z-track method is typically used for adults. Asking parents to leave may cause more anxiety.
Explanation:
In providing atraumatic care for a 4-month-old during immunizations, the most appropriate action would be to provide a sucrose solution on the pacifier. This is because sucrose solutions have been shown to have analgesic effects in infants, reducing pain and discomfort during procedures such as immunizations. The other options are not advisable. Administration of aspirin is not recommended for infants due to the risk of Reye's syndrome. The Z-track method is typically used for deep intramuscular injections in adults, not infants. Asking parents to leave the room during the injection may cause additional stress and anxiety for the child.
