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. While it's possible that a worsening health state could contribute to non-adherence, it's unlikely to be the sole factor, especially given that the patient has been explained the medication regimen multiple times.
B. While motivation is important for adherence, it's also unlikely to be the sole factor. Many patients with chronic conditions experience challenges with motivation, but effective education and support can help address this.

C. This is the most likely explanation for the patient's repeated non-adherence to the medication regimen. Health literacy refers to an individual's ability to understand and use health information to make informed decisions.
D. This is a possibility, but it's important to rule out other factors first. Cognitive impairment would likely manifest in other areas of the patient's life as well, and it's important to conduct a thorough assessment to determine if this is the case.
