Scenario A: A patient who has poison ivy has been taking over-the-counter (OTC) diphenhydramine (Benadryl) for itching. The doctor has told the patient to take 50 mg every six hours as needed. The medication is available in a 12.5 mg/5 mL solution. 1. How many milliliters the patient will need for each dose? 2. If the patient takes three doses per day, how many milliliters will the patient need to last three days? 3. How many 4 fluid ounce bottles (120 mL/bottle) will the patient need to purchase? Scenario B: A patient has brought her newborn infant into the pharmacy. She said that the baby weighs 9 (1)/(2) lb. 4. What is the infant’s weight in kilograms? Scenario C: You receive a prescription for an antibiotic suspension of amoxicillin 125 mg/5 mL. This medication is for a pediat¬ric patient weighing 20 kg, and it is determined that each dose should be 25 mg. 5. How many milliliters are needed for each 25 mg dose? 6. The patient needs to take two doses per day for a total of 50 mg. How many milliliters are needed for 50 mg of medication? 7. The total prescription requires that 500 mg of medication be dispensed. How many milliliters are needed to equal 500 mg of amoxicillin? 8. How would you express the concentration of amoxicillin in mg/10 mL? Scenario D: You are compounding a diluted bleach solution that requires 50 mL of bleach. You use a graduated cylinder and measure 50 mL. When you verify the amount using a more accurate graduated cylinder, the actual amount is 48 mL. 9. What is the percentage of error? 10. Is this percentage of error within an error tolerance range of 5%?
