A charge nurse notices that staff nurses are having difficulty using new IV infusion pumps for medication administration. Which of the following is the priority action by the charge nurse?

The correct answer is B: Assess the staff nurses' knowledge deficit. This is the priority action because it allows the charge nurse to identify the root cause of the difficulty staff nurses are having with the new IV infusion pumps. By assessing their knowledge deficit, the charge nurse can determine if additional training, education, or resources are needed to support staff in using the pumps effectively. Demonstrating the use of the pump (choice A) may be helpful but does not address the underlying issue of knowledge deficit. Pairing nurses (choice C) may not address the root cause and could potentially overwhelm the experienced nurse. Planning an in-service education program (choice D) is a good idea but should come after assessing the knowledge deficit to ensure the program is targeted and effective.
