An Adult Comes into Your Pharmacy with a Deep Puncture

An adult comes into your pharmacy with a deep puncture wound in his foot from stepping on a rusty nail in his backyard. He has cleaned the wound and is looking for bandages. He also tells you he hasn't had a tetanus shot in 25 years. Which of the following would be a reasonable statement concerning a tetanus booster shot?

A) He is overdue for a booster shot-one should be given every ten years and now would be an appropriate time.
B) A booster shot won't help him now-it is only useful before a puncture wound occurs.
C) An adult should never get a tetanus shot as it has been proven to cause neurological damage.
D) None of the above are true statements.
