Final answer:
The most appropriate management for a 48-year-old male who received the tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccine 9 years ago during a follow-up visit for hypertension would be to administer a Tdap booster vaccine.
Step-by-step explanation:
The most appropriate management for a 48-year-old male who is evaluated during a follow-up visit for hypertension and received the tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccine 9 years ago would be to administer a Tdap booster vaccine. The Tdap vaccine provides protection against tetanus, diphtheria, and pertussis.
The CDC recommends a Tdap booster every 10 years for adolescents and adults. Since the patient received the previous vaccine 9 years ago, he is due for a Tdap booster.
By receiving the Tdap booster vaccine, the patient will ensure continued protection against tetanus, diphtheria, and pertussis.
