A nurse is preparing to administer a tetanus and diphtheria toxoids (Td) to a client. Which of the following images indicates the technique nurse should plan to use?

A: Image A shows an injection being prepared at the deltoid muscle, which is the correct site and technique for administering the tetanus and diphtheria (Td) vaccine. The Td vaccine should be given intramuscularly, typically into the deltoid muscle of the upper arm in adults, using a 90-degree angle to ensure proper muscle penetration. B: Image B shows an injection technique appropriate for intradermal or possibly subcutaneous injection, indicated by the shallow angle of insertion into the skin. This method is not correct for a Td vaccine, which requires intramuscular administration for proper absorption and effectiveness.
