purpose of these labs is to investigate and determine how three factors- concentration, temperature, and a catalyst- affect the rate of a chemical reaction. In the first lab, “Rate of Chemical Reaction,” 1 x 8-well micro strips were used to combine a potassium iodate solution and a sodium meta-bisulfite solution under different conditions; each trial was timed from the point of the first visible reaction until the last well reacted. Likewise, in the second lab, “Factors Affecting Reaction…

The profession of nursing requires an individual to adhere to a set of ethics to guide deliberation and action while caring for patients. As stated by Burkhardt and Nathaniel, “codes of nursing ethics explicitly state that respect for persons is a cornerstone of professional ethics” (pg. 59). Along with respect for persons, there must also be principles such as autonomy, beneficence, non-maleficence, veracity, confidentiality, justice and fidelity followed when practicing as a professional nurse…

want to stay healthy for many, many years, you’ve got to start paying attention to the foods you eat, and choose ones that are loaded with beneficial nutrients. There are three powerful nutrients that every body should focus on for good health. Potassium…

The group 1 alkali metals are very reactive when put in water, as it produces hydrogen gas and alkaline solution (alkali metal hydroxide). The alkali metals reacts very fast and violent with water, as when you place the metals (lithium, sodium or potassium)…

Drug Profile The generic name is Amiloride, and the trade name in New Zealand is Amizide [1]. The Drug class of Amiloride is potassium-sparing diuretics, it is a medication that increases urination without losing potassium [2]. The formulation of Amiloride is 10 tablets of 5mg Amiloride with 20ml of glycerol, then adding 0.1% Parabens, finishing with water makeup to 50ml in total. The final product containing 1mg Amiloride per ml [3]. Amiloride is indicated as adjunctive treatment with thiazide…

detected early. One thing that can happen to our pets is hypokalemia, which can be potentially fatal. What is hypokalemia? The simple definition is low blood potassium. But what is going on inside the body when a dog has hypokalemia? Potassium is normally stored inside the body’s cells, which helps with normal cellular function. When these potassium levels drop, there is a change in the concentration gradient cells. This causes electrical charges not to pass through cells correctly. As the…

have the highest value of nutrients for plants to grow in and a soil composition that is fit for food production (ex. Water Holding, etc). To test our hypothesis, we ran tests measuring Percent Water Content, Organic Material, Nitrates, Phosphates, Potassium, and Percent Sand, Silt, and Clay. The first test we conducted was the Percent Water Content; to determine the value, we massed soil in a tin cup, heated the tin cup and soil in the microwave for 24 hours, and then re-massed…

electrolytes found within the body include calcium, magnesium, potassium, sodium, phosphate and chloride. For electrolytes to play their role efficiently they must have a balance of calcium, magnesium, potassium, sodium, phosphate, and chloride. You lose the balance of the…

changing VM values. As extracellular potassium concentration is systematically increased, membrane voltage should be rendered more positive (less negative). Indeed, if [K+]i is 140 mM (according to Bernstein’s model), extracellular [K+] much smaller than 140 mM (e.g., 5.4 mM, 10 mM) should elicit a large efflux of potassium ions, as reflected in the first two EK values listed in Table 1. As extracellular [K+] nears 140 mM, the strength of the outward potassium current should decrease, as…

chemical imbalance known as diabetic ketoacidosis (DIABETES.ORG). DKA causes osmotic diuresis which results in urinary losses of water and electrolytes (sodium and potassium). Potassium levels are initially elevated, however with insulin therapy, potassium shifts into cells and causes hypokalemia (ATI BOOK). Certain stressors and drugs can cause DKA include: acute infection, trauma, pancreatitis, stroke, corticosteroids, thiazide diuretics, and sympathomimetic. Signs and symptoms of DKA…
