How do you handle a patient with hypovolemic shock? Treatment revolves around controlling loss of fluid and blood, replacing what’s been lost, and stabilizing damage that both caused and resulted from the hypovolemic shock. This will also include treating the injury or illness that caused the shock, if possible. These include: blood plasma transfusion. Which […]

Is jealousy a sign of cheating? They get overly jealous If your partner gets irrationally jealous, it may be an indicator that they are transferring their own sense of guilt on to you. This type of projection is a classic way that cheaters try to cover up their own misdemeanors. What are the first signs […]

Why can some mixtures be separated by chromatography? Chromatography can be used to separate mixtures of coloured compounds . As the solvent soaks up the paper, it carries the mixtures with it. Different components of the mixture will move at different rates. This separates the mixture out. How many main ways are there to separate […]

What are examples of ratio variables? Examples of ratio variables include: enzyme activity, dose amount, reaction rate, flow rate, concentration, pulse, weight, length, temperature in Kelvin (0.0 Kelvin really does mean “no heat”), survival time. What are the 5 most common process variables? The most common process variables fall into five major types: level, flow, […]

Where is UV found? UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun. It is also produced by electric arcs and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. What is UV color? UV light has a shorter wavelength than visible light. […]

Why does oil make a rainbow in water? Most often seen in recently made puddles on the sides of roads, the oil refracts light much the same way a rainbow does. Simply put, the thin layer of oil floating on top of the water refracts the light which then bounces back up off the water […]

What is positive and negative charge in atoms? When an atom is attracted to another atom because it has an unequal number of electrons and protons, the atom is called an ION. If the atom has more electrons than protons, it is a negative ion, or ANION. If it has more protons than electrons,it is […]

What is Charles Law in simple terms? Charles’s law, a statement that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant. It is a special case of the general gas law and can be derived from the kinetic theory of gases under the […]

What do you mean by C * * * * * * * * * Frequency? Technically, a cumulative frequency distribution is the sum of the class and all classes below it in a frequency distribution. All that means is you’re adding up a value and all of the values that came before it. Cumulative […]

What is the charge for calcium ion? 2 What type of ion does calcium form? Calcium, Ca Calcium is also in Group 2. It has two electrons in its outer shell. When these electrons are lost, a calcium ion, Ca 2+, is formed. A calcium ion has the same electronic structure as an argon atom […]
