Final answer:
Puncture wounds can cause hidden internal bleeding with minimal external bleeding, have a strong possibility of contamination, and may involve an object impaled in the body that needs to be removed.
Step-by-step explanation:
One of the concerns with a puncture wound is the hidden internal bleeding with minimal external bleeding. Puncture wounds can create an opening in the skin that allows blood to accumulate internally without much visible bleeding. Another concern is the strong possibility of contamination.
Puncture wounds can introduce bacteria and other pathogens deep into the tissues, increasing the risk of infection. Additionally, the object that remains impaled in the body can pose further complications and should be removed in a medical setting.
