This paper demonstrates detailed solutions to a series of pharmacological problems, including dilutions, concentration calculations, infusion rate determinations, and dose safety assessments, highlighting essential drug calculation skills vital for pharmacy and nursing practice. Question 1 and 2: Preparing a Solution with a 1:8 Concentration The problem requires preparing 400 mL of a solution where the drug concentration ratio is 1:8. This ratio typically indicates that 1 part of drug is in 8 parts of diluent. To achieve this, we first determine the amount of drug needed based on the total volume of the solution. Given the total volume (V_total) is 400 mL, and the ratio is 1:8, we understand that the total parts sum to 9 parts (1 part drug + 8 parts diluent). Therefore, the fraction of the drug in the solution is 1/9 of the total volume. Calculating the drug volume: - Drug volume = (1/9) × 400 mL ≈ 44.44 mL - Diluents volume = 400 mL - 44.44 mL ≈ 355.56 mL Assuming the drug's concentration is such that the drug volume corresponds to the pure drug needed: - If the drug is to be prepared from a stock solution, the amount of drug in grams or milligrams would depend on the stock concentration. However, since the problem states 'how much drug do you need,' without specifying concentration, we interpret it as the volume of drug to be added. Therefore, the necessary volume of drug to add is approximately 44.44 mL. The amount of diluent needed (sterile water) is approximately 355.56 mL. Question 3: Calculating V1 in a Dilution Problem Given: - V2 = 200 mL - C1 = 80% - C2 = 50% Using the dilution formula: V1 × C1 = V2 × C2 Solving for V1: V1 = (V2 × C2) / C1 V1 = (200 mL × 50%) / 80% V1 = (200 × 0.50) / 0.80 V1 = 100 / 0.80 V1 = 125 mL Thus, the initial volume (V
