Which strategy would the nurse apply when vaccinating a child to decrease pain and anxiety?

Choice A rationale Administering the most painful vaccination first may increase the child's distress and anxiety during the entire process, potentially leading to fear of future healthcare visits. Best practice involves administering the most painful injection last to avoid maximizing pain perception and anxiety and to enable faster parental comforting after the most uncomfortable part. Choice B rationale Aspirating the syringe prior to administering a vaccination is no longer generally recommended by major health organizations for routine intramuscular pediatric vaccinations. This practice does not decrease pain and anxiety and may actually increase injection time, potentially causing more discomfort, though it is still taught in some older curricula. Choice C rationale Administering acetaminophen after vaccination is primarily used to treat fever or localized pain that may occur after the procedure, not to decrease pain and anxiety during the actual injection. The drug takes time to become effective, so it offers no immediate benefit for procedural anxiety or pain relief. Choice D rationale Holding a child in a comfort position, such as securely in the parent's lap, provides physical restraint and emotional security, which are highly effective non-pharmacological methods to decrease pain perception, anxiety, and distress during needle procedures. This strategy allows the child to feel safe and supported by a trusted caregiver.
