In reviewing the current delivery model, the nurse manager is aware that a demographic change that will have a significant effect on healthcare delivery systems of the future is:

A. “Read the room” is not one of the four agreements presented by Don Miguel Ruiz. This phrase is often used in everyday language to describe the act of understanding the mood or dynamics of a situation, but it is not one of the agreements outlined in the book. The four agreements focus more on personal conduct and attitudes rather than interpreting social situations.
B. This is one of the four agreements. It encourages individuals to avoid assuming things about others or situations without clear evidence. Making assumptions can lead to misunderstandings and conflicts. The agreement advocates for clear communication and asking questions rather than making unfounded assumptions.
C. This is also one of the four agreements. It advises people not to take the actions or opinions of others personally, as these are often reflections of the other person's own issues and not a direct reflection of oneself. This agreement helps in reducing unnecessary emotional suffering and maintaining inner peace.
D. This is another of the four agreements. It emphasizes the importance of speaking with integrity, saying only what you mean, and avoiding using words to harm others or yourself. Being impeccable with your word fosters trust and respect in communication.

A. Waiting for the patient to leave before filing an incident report is not the most appropriate response. The immediate priority should be addressing the situation to ensure the patient's safety and attempting to resolve any issues before the patient leaves.
B. Contacting the patient’s next-of-kin can be appropriate if the nurse is concerned about the patient’s safety and if it’s necessary to inform the family about the patient’s condition or situation. However, this should be done only after attempting to address the situation directly with the patient, if feasible. It’s important to first try to resolve the issue directly with the patient before involving family members.
C. Walking with the patient and explaining the risks of leaving against medical advice (AMA) shows a proactive approach to addressing the patient's concerns and ensuring they understand the potential consequences of their actions. This approach aims to de-escalate the situation, provide important information, and potentially encourage the patient to stay for necessary care.
D. Calling security personnel should be a last resort and is generally used in situations where there is a safety threat or risk of harm. In this case, the patient is leaving in a disgruntled state but not exhibiting violent or threatening behavior.
