What factors determine syringe selection?

• A. Purpose of injection, the volume of vaccine to be injected, and the need for accuracy in dosage
• B. Price of the syringe
• C. The color of the syringe
• D. Brand of syringe

Answer: (A)

Syringe selection is driven by how the vaccine is given, how much needs to be injected, and how precisely that amount must be measured. The route of administration changes what you need: intramuscular injections require reaching the muscle with a longer needle and a syringe that allows accurate dosing for the chosen volume; subcutaneous injections use a shorter needle and typically smaller volumes, so a syringe with clear, appropriate markings helps ensure the dose stays within the intended range; intradermal injections involve very small volumes and require fine graduations to deliver the tiny amount accurately. The amount of vaccine also matters for accuracy: when the dose is small, using a syringe with precise, small-volume markings helps prevent under- or overdosing. Price, color, or brand don’t determine the correct choice for administration—they may affect convenience or availability, but the essential factors are route, volume, and accuracy.
