Tetanus Immunity Posttest

Tetanus Immunity Posttest

• Question 1: A 23-year-old student bitten by a mouse needs tetanus immune globulin (human) for passive immunization.

• Question 2: A 10-year-old with a deep laceration and no previous tetanus immunization should receive tetanus toxoid and tetanus immune globulin (human) injections, separated by a couple of weeks.

• Question 3: A 3-year-old patient with a deep puncture wound and deficient humoral immunity should receive passive immunization with tetanus immune globulin (human).

• Question 4: Administration of tetanus immune globulin (human) to a 6-year-old requires consideration of short antibody half-life, and the possibility of serum sickness or anaphylaxis.

• Question 5: Serum sickness can result from an injection of tetanus antitoxin (equine).

• Question 6: Active immunization is advised if the incubation period of the disease is longer than the time required to generate immunity through active immunization methods.

• Question 7: A 10-year-old with a deep puncture wound and a previous tetanus immunization should receive tetanus toxoid for active immunization.

• Question 8: Diphtheria toxoid, like tetanus toxoid, is both immunogenic and antigenic and thus an effective inducer of active immunization.

• Question 9: Tetanus toxoid injection induces antibody-mediated and active immunity.

• Question 10: Passive antibody administration provides antibody more rapidly than active immunization.

• Question 11: Antibody is a protein produced by the body in response to antigens to combine with them.

• Question 12: Antigen is a substance that triggers the body's immune response and with which antibodies bind.

• Question 13: Immunity is the body's ability to resist infection or disease.

• Question 14: Passive antibody administration is warranted in patients with fresh wounds that may be infected with Clostridium tetani, especially if they have no history of active tetanus immunization.

• Question 15: An experiment to determine the importance of cell-mediated immunity in bacterial disease protection involves transferring T-cells from immune mice to normal mice, and then introducing a bacteria into both groups of mice. Observing the results of the experimental mice and comparing them to the control group gives data.

Posttest Answers

• Answer 1: Active immunity is faster than passive immunity.

• Answer 2: Public Health Service approves the use of tetanus toxoid and immune globulin.

• Answer 3: Passive immunization with tetanus immune globulin is the best treatment.

• Answer 4: Antibody half-life and possible complications should be considered.

• Answer 5: Serum sickness is associated with tetanus antitoxin, not tetanus immune globulin.

• Answer 6: Active immunization is generally preferred in the case of longer incubation periods.

• Answer 7: Tetanus immune globulin is the preferable method.

• Answer 8: Diphtheria toxoid, similar to tetanus, is immunogenic and antigenic.

• Answer 9: Tetanus toxoid induces active immunity through production of antibodies.

• Answer 10: Passive antibody administration provides a quicker immune response; the antibody response is critical for early protection.

• Other notes: -Active vs passive immunization: Active induces the body's to generate immunity from a vaccine/toxin; passive provides pre-made antibodies from another source. -Passive is quicker but generally shorter-lived than active. -Prior immunization history is crucial for treatment decisions.

Test your knowledge on the administration of tetanus immunizations and the considerations for different age groups and medical histories. This posttest covers scenarios involving passive and active immunization methods, as well as potential side effects like serum sickness. Assess your understanding of tetanus immunity protocols in various patient cases.
