Isotonic

Water is essential in keeping the body in balance. There are two significant compartments of the body that exchange fluids and electrolytes to maintain homeostasis, which are intracellular and extracellular. These two spaces continually interchange electrolytes, particles, and water to sustain the same pressure. (PP chap42 pg935) This paper will describe three machinimas that assists in maintaining homeostasis, four main categories of IV therapy, and nursing consideration in relation to infusing…

all patients should be aggressively hydrated with the first 24-48 hours with isotonic crystalloids unless they are contraindications. Patients with concurrent acute cholangitis should undergo endoscopic retrograde cholangiography (ERCP). Antibiotics is only recommended if there is an extra-pancreatic infection such as bacteremia or…

throughout, the solutions in the bag changed from a clear color to a light blue color due to the influx of iodine indicating the presence of starch. Although water molecules are polar, they are small enough to move across the membrane until it reaches an isotonic solution. There was also now a presence of glucose in the…

The purpose of experiment A of exercise 1, is so that the students can observe Brownian movement. Brownian movement is the random movement of particles in a gas or liquid caused by the collision of molecules of the medium. This movement should be observed in the carmine slides by the irregular motion of the red pigment particles in the water solution. In experiment B of exercise 1,the students will investigate the process of osmosis and diffusion in a model membrane system and the effect of…

This experiment determined how solute concentration affected the rate of osmosis in a cell and the outside environment. Three pieces of dialysis tubing were used as three different cells, each filled with different solute concentrations. Each one of the cells was placed in one of three beakers that were filled with tap water. The masses of each of these cells before being placed in the beakers, and afterwards in ten minute intervals for an hour. The percent difference between the initial mass…

The purpose of the osmosis experiment was to observe the diffusion of solutes and the osmosis of water through a semipermeable membrane, which was dialysis tubing. This experiment was done to examine, if the solution is hypertonic, hypotonic or isotonic. The result of this experiment was that tube 5 and 6 decreased in mass. Tube 2, 3 and 4 increased in mass. This is because in the hypertonic solution, water in the tube was flowing outwards, because the concentration of dissolved…

permeable to starch and, or, iodine. Also, to find out wither potatoes are hypotonic, hypertonic, or isotonic by testing the different amounts of sucrose solutions Introduction: The necessary background information needed for this lab is the definition of osmosis, diffusion, active transports, passive transports, permeability, concentration, tonicity, and to now the scientific concepts of hypotonic, isotonic, and hypertonic. Hypothesis: For part 1 my hypothesis is: That the starch will…

hypotonic solution to a hypertonic solution to make an isotonic solution (Reasoner 2011). This helps the body maintain homeostasis. A principle of osmosis is that water molecules move through the plasma membrane, for the solute molecules cannot (Tortora and Derrickson 2014). Solutes are also able to use force, called osmotic pressure, in a solution with impermeable solutes. There are three osmotic conditions referred to as hypertonic, hypotonic, and isotonic, which all describe the state of the…

hypo and isotonic solutions work best in in-vivo modeling of vaso-occulsive episodes. In times of hypoxia, oftentimes patients with sickle cell disease can experience increased deformations of their red blood cells, which an adhere to the microvasculature of bones or the spleen and cause pain. Before this review, it was unsure how tonicity of intravenous replacement fluid impacted the resolution of the pain episodes. Carden and his team used human blood to determine that hypotonic and isotonic…

The purpose of this experiment is to study how water and other molecules enter and leave cells. Water has the ability to move in and out cells through the process of osmosis. The methods performed include using three different solutions: Gatorade, Karo syrup, and Coca-Cola. A decalcified egg is submerged for various amounts of time in each solution and weighed, using an electronic scale, to calculate the percent weight change. The results for each solution showed that the egg did take on…
