Post Nasal Drip (or PND). Mucus draining down the back of the throat over the back of the tongue where the bad breath bacteria live. They feed off the proteins in mucus and create strong odors. If you still have your tonsils, you may be harboring a higher number of the bacteria in the crevices of your tonsils.
Phenomena are identified from nursing practice. Nursing theories describe these phenomena or provide a framework to deal with these questions or problems. Nursing research is used to describe the phenomena or address the questions and problems. The results of nursing research are then applied to nursing practice.
A nursing theory, also called a nursing model, is a framework developed to guide nurses in how they care for their patients. Often, these frameworks define the practice of nursing, identify the role of the nurse, and explain the nursing process as it relates to the idea behind the nursing theory.
