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

A) An accepted method for understanding the world and what is in it: This option is a general description of theory but does not specifically define middle-range theory. Middle-range theory is a specific type of theory within the nursing field.

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.

A) Establishes the physician as the primary and sole source of authority during codes:
This statement is incorrect. The SBAR system does not establish the physician as the sole authority. It's a communication tool designed to enhance collaboration and understanding between healthcare professionals, ensuring effective communication during critical situations.

B) Reduces confusion in the communication between nurse and physician:
This statement is correct. One of the primary roles of the SBAR system is to reduce confusion and enhance the clarity of communication between nurses and physicians. By providing a structured framework (Situation, Background, Assessment, Recommendation), it ensures that crucial information is communicated clearly and effectively, especially during critical situations.

C) Aids nurses in independent practice when necessary:
This statement is partially correct. While the SBAR system aids in communication, it does not specifically address independent practice. It focuses on improving interprofessional communication, which is essential for collaborative care.

D) Reduces the number of lawsuits associated with the care of critically ill clients:
This statement is incorrect. While clear communication can contribute to better patient outcomes and potentially reduce the risk of errors, the SBAR system itself does not directly impact the number of lawsuits. Lawsuits are influenced by various factors, including the quality of care, documentation, and adherence to established protocols.
