Final answer:
Using a high-fidelity patient simulator is the best method to teach staff nurses CPR because it allows for realistic, hands-on practice and feedback in a safe environment.
Step-by-step explanation:
The nurse managers decide to use a high-fidelity patient simulator for teaching the staff nurses cardiopulmonary resuscitation (CPR) because it is the best method to provide realistic, hands-on practice and feedback.
High-fidelity patient simulators mimic real patients and can simulate different clinical scenarios.
By using a simulator, staff nurses can practice CPR techniques, improve their skills, and familiarize themselves with the equipment and procedures in a safe and controlled environment before applying them to real patients.
