Math Review Session 4 - 7 Questions (Percent Strengths & Concentrations)

Pharmacy Math Review Session 4: Proportions, Percent Strength & Unit Conversions (Practice Problems) This math review session walks through pharmacy calculation problems using the “Uncle Charlie Sings” method (identify unknown/known values, conversions, and a part-per-whole proportion setup). The instructor solves for hydrocortisone ointment needed to compound a 4 oz prescription from a 1500 g formula (4 oz to 120 g; answer about 36 g), finds the drug dose from a 7.5% solution for a 1 tsp (5 mL) dose (0.375 g), calculates grams of urea for 2.5 L of 25% solution (2,500 mL; 625 g), determines mL needed for 1,000,000 units of penicillin G from 250,000 units/mL (4 mL), computes hydrocortisone powder for 1 lb of 4% ointment (454 g; 18.16 g), and finds sodium bicarbonate for 50 mL of 0.5% solution (0.25 g = 250 mg). 00:00 Question 1: Hydrocortisone needed for compounded prescription 06:17 Question 2: Calculate dose from percent solution 10:54 Question 4: Calculate urea in solution 14:38 Question 5: Calculate units of penicillin G 19:29 Question 6: Calculate hydrocortisone powder in 4% ointment 21:51 Question 7: Calculate sodium bicarbonate in 0.5% solution
