When performing blood collection, what is a safe procedural step after withdrawing the needle from the artery?

Applying pressure to the artery after withdrawing the needle is essential to prevent excessive bleeding and to promote hemostasis, or blood clotting. When a needle is removed from an artery, it creates an opening that can lead to blood loss. By applying consistent pressure to the site, you help to close the vessel and reduce the risk of hematoma formation or significant blood loss, ensuring the animal's safety and well-being.

Other options are not appropriate immediate steps following blood collection. For instance, applying ice might be useful for reducing swelling or discomfort in some contexts, but it does not address bleeding. Allowing the animal to walk around can increase the risk of bleeding, as movement may disrupt the clotting process. Monitoring for breathing is important in general animal care but does not directly relate to the immediate concerns following blood withdrawal from an artery.
