A public health nurse will be administering immunizations at a clinic. Which of the following will the nurse want to ask each client before administering the vaccine to ensure safety?

A. If they have had any past issues or allergies to the vaccine: Screening for previous allergic reactions or adverse events is critical to prevent severe reactions such as anaphylaxis. This safety check is a priority before any immunization. B. If there are any questions regarding the client’s vaccine schedule: Addressing questions about the schedule is important for education and adherence but does not directly prevent an immediate adverse reaction. Safety screening takes precedence. C. If they have an immunization card for documentation: Having a record ensures proper documentation and tracking of vaccines but does not impact the immediate safety of vaccine administration. D. If they have a site preference for vaccine administration: While patient comfort is considered, site preference does not affect the safety or effectiveness of the vaccine. Priority is screening for allergies and contraindications.
