Which is not a primary source for organ and tissue donation?

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 related donors: These are individuals who are biologically related to the recipient, such as parents, siblings, or children. They can donate organs like kidneys or portions of the liver.

Living unrelated donors: These are individuals who are not biologically related to the recipient but are willing to donate an organ while alive, typically through altruistic or paired exchange programs. This could include friends or unrelated individuals who are a match.

Cadaver donors (Deceased donors): These are individuals who have passed away, and their organs and tissues can be donated for transplantation. Deceased donors can provide organs like hearts, lungs, kidneys, liver, pancreas, and tissues like corneas, bones, and skin after death.

Cadaver animals: Animals are not used as primary sources for organ and tissue donation for human transplantation. Organ transplantation primarily involves human donors, either living or deceased.
