A person has received complete immunization against tetanus 10 years ago. Now he presents with a clean wound without any lacerations from an injury sustained 2.5 hours ago. He should now be given
**Core Concept**
The individual in question has received complete immunization against tetanus 10 years ago, placing them in a category of low risk for tetanus infection. However, the wound's exposure to tetanus spores remains a concern, necessitating the administration of tetanus toxoid to maintain immunity.
**Why the Correct Answer is Right**
The administration of tetanus toxoid (option C) is justified due to the potential for tetanus spores to be present in the environment. Even with complete immunization, booster shots are essential to maintain adequate tetanus antibody levels, especially in individuals with a history of exposure to tetanus spores. This is in line with the Centers for Disease Control and Prevention (CDC) guidelines recommending tetanus toxoid booster shots every 10 years for individuals with a history of complete immunization.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not address the need for tetanus toxoid booster shots in individuals with a history of complete immunization.
**Option B:** This option is incorrect as it does not provide any immunity against tetanus infection.
**Clinical Pearl / High-Yield Fact**
It is essential to note that the administration of tetanus toxoid is not dependent on the wound's cleanliness or severity but rather on the individual's immunization status and potential exposure to tetanus spores.
**Correct Answer:** C. Tetanus toxoid booster shot.
