Vitamin K plays a crucial role in blood coagulation, activating proteins that form blood clots. A deficiency in this fat-soluble vitamin impairs this process, a clinical principle frequently examined in medical multiple-choice questions (MCQs).

According to research published by the National Institutes of Health, while often used interchangeably, the medical term for lack of fluids, or dehydration, is distinct from hypovolemia. Dehydration refers to an overall deficit of total body water, whereas hypovolemia specifically indicates a reduced volume of blood circulating in the body.

Water constitutes a significant portion of the adult body, averaging around 60% in males and 55% in females. Understanding this is fundamental to grasping **what is the formula for calculating sodium deficit?**, a critical medical tool used to quantify and correct dangerously low blood sodium levels, also known as hyponatremia. This calculation helps clinicians determine the appropriate course of action, which is often influenced by dietary and hydration factors.
