Mr. Mariano was on his way home from a party. Apparently, he got drunk and lost his balance and suffered a vehicular accident. Upon arrival at the hospital, the nurse noticed that his only injury is an open fracture of the left humerus. Which assessment finding by the nurse is critical?
Correct Answer: A
Rationale: In this situation where Mr. Mariano has an open fracture of the left humerus, the nurse's critical assessment finding should be the status of the client's tetanus immunization. An open fracture poses a risk of infection, and tetanus is a concern due to the potential exposure to bacteria from the environment causing tetanus. Tetanus is a serious bacterial infection that affects the nervous system and can be fatal if not treated promptly. Knowing the client's tetanus immunization status will help determine the need for a tetanus booster to prevent this potentially life-threatening infection. Blood alcohol level, support systems at home, and voiding time are important assessments as well, but in the case of an open fracture, the priority is to assess the risk of tetanus infection.
