Clinical information is your bedrock. Family members who do not have experience with providers or the understanding of the situation you have gained may dispute you at every turn. This is normal. Their aggression can certainly trigger an emotional response. You'll lose it at times. Forgive yourself. Get some rest.
Listen carefully to information provided. Take time to consider it before asking questions that may have already been answered or cannot yet be answered. Remember that providers are fellow humans, subject to all the emotional challenges you are experiencing.
Family members who are not directly involved in caretaking may have strong feelings about what is being done. These feelings can come out as forceful opinions or judgment of your efforts. Recognize that these feelings are normal during times of high stress.
A leader’s first challenge is to understand the current problem and its cause(s), the movement of the marketplace and what it portends for the future, and the resources available to the organization to correct course and adapt to the changing landscape.
