19. You are to prepare 30 ml of a Clindamycin 6 mg/ml pediatric dilution. The stock vial comes in Clindamycin 150 mg/ml. The diluent you are to use is NS. How many milliliters of concentrate will you use for the dilution? a. The dose of clindamycin is, 6 mg/ml. Total volume is, 30 mL. Concentration of clindamycin in the stock vial is, 150 mg/mL The required concentration is, 6 mg/mL. The required volume is, 30 mL, which contains 180 mg of clindamycin. The number of millimeters of diluent needed is, 1 mL 150 mg X 6 mg X 6 mg 1 mL/ 150 mg; X 0.04 mL Thus, 0.04 mL of the stock solution contains 6 mg of clindamycin. 1.2 mL (= 0.04*30) of stock solution contains 180 mg of clindamycin. Thus, take 1.2 mL of the stock and make up the volume to 30 mL. b. How much diluent will be needed? The volume of diluent is, 30-1.2 28.8 mL
