Hоw shоuld the scenаriо thаt follows be evаluated with respect to the goal of encouraging the nursing assistant to be accountable for learning skills? Nursing assistant: "I do not know how to use the new lifting device. I missed the demonstration the other day." Long term care charge nurse: "I will ask another nursing assistant if he has time to get your patient out of bed with the new device while you assist. How do you think you can prepare yourself to use the new device in the future?" Nursing assistant: "I will watch him closely when I assist him and ask questions. Then, I guess I could watch the DVD later today that came from the company and practice with the help of other nursing assistants tomorrow morning when they have time." Long term care charge nurse: "Good plan. I will plan to observe and evaluate your competency tomorrow afternoon."
