Which of the following types of syringes deliver large doses repeatedly?

• A. Manual
• B. Tubular
• C. Automatic
• D. Hypodermic

Answer: (C)

Delivering large doses repeatedly relies on a device that can consistently dispense a fixed volume with minimal manual effort. Automatic syringes are built to deliver a set amount with each actuation and can progress through many doses in succession without needing to reset or manually pump each time. This makes them ideal for administering large volumes to multiple animals quickly and with uniform accuracy. In contrast, manual syringes require the operator to squeeze and control the plunger for every dose, which is slower and can introduce variability due to fatigue or changing hand pressure. A hypodermic syringe is a standard syringe used for individual injections and small volumes, not optimized for rapid, repeated large-volume dosing. Tubular syringes are not designed for repeated precise dosing of large amounts, so they’re not as suited to this purpose.
