Final answer:
After advancing a Penrose drain, you should not cut off the excess drain.
Step-by-step explanation:
After advancing a Penrose drain, you should not cut off the excess drain. The Penrose drain is a soft, flexible tube that is used to drain fluid from a wound. It is left in place to allow the wound to heal and drain properly. Cutting off the excess drain may prevent the drain from functioning effectively and may increase the risk of complications.
