What key concepts are commonly found in nursing theories and models? (Select all that apply.)

Use of systems theory.
Neuman's Health-Care Systems Model is based on the principles of systems theory. The model views individuals as open systems interacting with their environment. Health, illness, and wellness are influenced by dynamic interactions between the client and environmental stressors. This systems-based approach helps nurses understand the holistic nature of clients and their responses to stressors.

Behavior is the key to preventing illness.
This statement does not accurately represent Neuman's Health-Care Systems Model. While behavior and lifestyle choices can influence health, Neuman's model primarily emphasizes the dynamic interactions between individuals and their environment, considering stressors and their impact on the client's stability and well-being.

Nurse-centered rather than client-centered.
Neuman's model is client-centered. It focuses on the client's responses to environmental stressors and aims to assist clients in maintaining their optimal wellness within the context of their environment. It is not nurse-centered; instead, it empowers clients to actively participate in their own care.

Alteration of environmental stressors leads to health.
While addressing environmental stressors is a component of Neuman's model, it does not directly state that altering these stressors leads to health. The model emphasizes understanding the client's response to stressors and helping them achieve stability despite these stressors.

Living will: A living will is a legal document in which a person specifies what actions should be taken for their health if they are no longer able to make decisions for themselves due to illness or incapacity. It outlines the medical treatments an individual would like to receive or not receive, particularly in end-of-life situations.

Client's Bill of Rights: This document outlines the rights and responsibilities of clients receiving medical care. It does not specifically contain a client's written wishes about healthcare decisions in case of incapacity.

Welfare rights: Welfare rights refer to the legal rights of individuals to receive assistance from the government, typically in the form of financial aid or social services, to meet basic needs like food, shelter, and healthcare. This is not related to healthcare decision-making for incapacitated individuals.

Informed consent: Informed consent is the process where a patient is informed about the potential risks, benefits, and alternatives of a medical procedure or treatment. While important for medical decision-making, it is not the specific document where a client's written wishes about healthcare decisions are recorded for situations where they are unable to make decisions themselves.
