NURS 225 Chapter 35: Electrolyte Review
Document Summary
225 chapter 39 electrolytes: 1 kg (2. 2 lbs. ) of weight equals: 1 l of water: explain how the osmotic pressure can affect tonicity. Tonicity refers to the tension or effect that the effective osmotic pressure of a solution with impermeable solutes exerts on cell size because of water movement across the cell membrane. Osmotic pressure is defined as when water moves across the semipermeable membrane, it generates a pressure. This pressure is what we call osmotic pressure. So therefore, the specific osmotic pressure of a solutions ability to exert on cell size due to the water movement across the membrane: define the following classifications of solutions and what effect they have on the body. Isotonic cells will neither shrink nor swell; it has the same effective osmolality as the. It is typically characterized by a decrease in the ecf, also including the circulating blood volume. Many things can cause this to occur such as: inadequate.
