B) An in-depth review of the literature concerning a particular item of study: This option describes a literature review, not a middle-range theory. While literature reviews are an essential part of developing theories, they are not the definition of a middle-range theory.

C) A set of relatively concrete concepts that lie between minor working hypotheses: Middle-range theories are more specific and focused than grand theories but broader than minor working hypotheses. They consist of concrete concepts and propositions that help explain and predict limited aspects of nursing practice. They serve as bridges between theoretical nursing models and actual nursing practice.

D) An organized unit with a set of components that interact and affect each other, a system that acts as a whole: This option describes a general concept of a system but does not specifically define middle-range theory.

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.
