When solving any problem, first check that the order and supply are in the same weight measure. For this problem, two equivalents are necessary (5 mL = 1 tsp and 1 g = 1000 mg). To convert 0.25 g to milligrams, move the decimal point three places to the right: 250 mg. Therefore, 0.25 g = 250 mg (0.25 g * 1000) and 5 mL = 1 tsp. Estimate the amount to give. Formula Method: 250 mg/125 mg * 5 mL = 1250/125 = 10 mL = 2 tsp. Proportion (Ratios): 5 mL : 125 mg :: x mL : 250 mg; 125x = 1250/125 = 10 mL = 2 tsp. Proportion (Fractions): 5 mL/125 mg = x mL/250 mg; 125x = 1250/125 = 10 mL = 2 tsp. Use two conversion factors for dimensional analysis. Dimensional Analysis: 5 mL/125 mg * 0.25 g *1000 mg/1 g *1 tsp/5 mL = 5 * 0.25 * 1000 * 1 tsp/125 * 1 *5 = 1250/625 = 2 tsp. For liquids, the four methods are set up just as for oral solids, except the supply includes a liquid measurement.
