Which of the following is not an accepted rule regarding the frequency of changing needles?

Change after every 10 injections
Change after every 25 injections
Change every 50 injections
Change after every 100 injections

The correct answer is: Change every 50 injections

Changing needles is an important practice in veterinary care to minimize the risk of infection, prevent tissue damage, and ensure the effectiveness of the administration. Among the choices provided, changing needles after every 50 injections is generally not an accepted rule, as it exceeds common guidelines that prioritize safety and health. Most recommendations suggest changing needles after a lower number of injections, typically after 10, 25, or 100, depending on the specific context of use. Frequent changes help maintain the sharpness of the needle and reduce the likelihood of introducing bacteria or causing other complications during injections. Adhering to these more conservative limits ensures better outcomes for animal health, making the choice of changing after 50 injections less advisable compared to other options provided.
