PREVENT Care 32 - sami2004 - ArchivalUser - 09-26-2010 A 13-year-old boy is brought into the emergency room with a laceration of his right arm. According to his parents, he received the injury when he fell on the ground while playing at the family farm about 1 hour ago. He has no known history of any medical problems. His parents say that they haven’t brought him to the doctor in years. On questioning, they report that he only received one of his “baby shots” and they are not sure which one that was. On examination, he is healthy appearing. He is appropriately apprehensive but calm and consolable. His right arm has a 5 cm linear laceration with visible soil particles in and about the wound. The remainder of his examination is unremarkable. You carefully clean and irrigate the wound and then primarily repair the laceration with sutures. What immediate tetanus prophylaxis would be optimal in this case? (A) IM injection of adult Td vaccine only (B) IM injection of both adult Td vaccine and tetanus immune globulin (TIG) © IM injection of Tdap only (D) IM injection of TIG only (E) IM injection of both Tdap and TIG 0 - ArchivalUser - 09-26-2010 B) IM injection of both adult Td vaccine and tetanus immune globulin (TIG) 0 - ArchivalUser - 09-27-2010 bb 0 - ArchivalUser - 09-27-2010 sorry i want to choose ee 0 - ArchivalUser - 09-27-2010 BB 0 - ArchivalUser - 09-27-2010 e... 0 - ArchivalUser - 09-27-2010 ee 0 - ArchivalUser - 09-27-2010 B Hate pediatrics! 0 - ArchivalUser - 09-27-2010 whats the ans sami? 0 - ArchivalUser - 09-28-2010 ANSWER IS E The disease tetanus is caused by an exotoxin produced by the anaerobic, gram-positive bacterium C. tetani. The spores of C. tetani are endemic in soil, particularly in agricultural areas. They can also be found in the intestines and feces of many animals. Human infection usually is the result of the introduction of the spores through a wound, such as a puncture or laceration. The spores can then germinate and toxins are released. Tetanus is characterized by unopposed muscle contractions and spasms. Autonomic nervous system manifestations, seizures, and difficulty swallowing may occur. Recovery may take months, but the disease is often fatal. In the developed world, most cases of tetanus occur in those who either were never vaccinated or who completed a primary vaccine series but have not had a booster in the preceding 10 years. The currently available vaccine is a toxoid which consists of a formaldehyde-treated toxin. It is available as a single antigen vaccine, combined with diphtheria (pediatric DT or adult Td) or combined with both diphtheria and acellular pertussis vaccine (DTaP). Whenever possible, tetanus toxoid should be given in combination with diphtheria toxoid to provide periodic boosting for both antigens. There is little reason to use single antigen tetanus toxoid alone. |
