Your answer:
X-Ray the hand looking for a foreign body.
Correct answer.
Both answers are correct. Each option is a choice that the
physician can make depending on their preference. An X-Ray of the
hand might be useful if a metallic foreign body is suspected
after examining the wound. This helps to localize the fragment
and may help in guiding the removal.
The most cost effective however would probably be another washing of the wound, possibly using hydrogen peroxide. Peroxide causes foaming while cleaning wounds. This gentle action may lift contamination from the wound. Phisohex, Dakin's solution, and betadine are all good choices as well. The first choice for the cleaning of any contaminated wound is the agent that would normally be used to clean the area anyway.
