Final answer:
A tetanus booster is recommended every 10 years, with option B) Booster every 10 years being the correct guideline. However, an earlier booster may be required if the last shot was over 5 years ago and the wound is severe or dirty.
Step-by-step explanation:
Guidelines for Tetanus Vaccine after a Penetrating Wound
After experiencing a penetrating wound, it's crucial to assess tetanus immunization status to determine whether a tetanus booster is needed. For someone who is up to date with their tetanus immunizations, a booster is recommended every 10 years to maintain immunity. However, if the wound is particularly dirty or severe, and it has been more than 5 years since the last booster, then an early booster may be administered. In situations where one is not up to date with tetanus vaccination, immediate tetanus prophylaxis should be given, and this may include both the tetanus immunoglobulin (TIG) and the tetanus vaccine.
In summary, the correct option according to standard health guidelines for when to administer a tetanus booster is option B) Booster every 10 years, although circumstances such as wound severity and time elapsed from last booster could necessitate an earlier booster.
