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

Vaccine administration guidelines emphasize minimizing trauma to the site rather than stimulating the area post-injection.Choice C rationaleObtaining informed consent is essential before administering any vaccine. This step ensures legal and ethical compliance, allowing guardians to understand the risks and benefits associated with the immunization.Choice D rationaleAspiration is no longer recommended in vaccine administration according to updated guidelines. Aspiration increases injection time and patient discomfort without evidence of enhancing safety.
