Question 1 When patients in a medical facility are given intravenous (IV) fluids, great care is taken to ensure that the correct concentration of electrolytes is present in the IV solution. The conductivity of an isotonic solution of sodium chloride (NaCl normal saline) in water is 1.6×10−21.6×10−2 Siemen. What can you predict about the amount of magnesium chloride needed to prepare a solution of MgCl2if the solution can only have a conductivity equal to normal saline? Why? A The amount of magnesium chloride would be greater than the sodium chloride, because the magnesium chloride is less soluble. B The amount of magnesium chloride would be less than the sodium chloride, because magnesium chloride produces more ions. C The amount of magnesium chloride would be greater than sodium chloride, because magnesium chloride produces more ions. D The amount of magnesium chloride would be less than the sodium chloride, because the magnesium chloride is more soluble.
