Guest guest Posted September 29, 2003 Report Share Posted September 29, 2003 A compounded prescription requires using 12 capsules costing $30.00 per 50 capsules and 120gm of an ointment base costing $7.50 per pound. If a $5.00 dispensing fee is included, how much should the patient be charged? Also, can someone please tell me if there's alot of these type questions on the real PTCB exam. If there is, I'm thinking about droping for Nov, 15. Quote Link to comment Share on other sites More sharing options...
Guest guest Posted September 30, 2003 Report Share Posted September 30, 2003 Dear Ph_beekcl andAll, A compounded prescription requires using 12 capsules costing $30.00 per 50 capsules and 120gm of an ointment base costing $7.50 per pound. If a $5.00 dispensing fee is included, how much should the patient be charged? Also, can someone please tell me if there's alot of these type questions on the real PTCB exam. If there is, I'm thinking about droping for Nov, 15. Yes there will be more than one probably about 3 to 5 questions like this for retail compounding math with variations. But then again who really knows what will be on the exam? Many have mentioned this type of math. First let us note that the quantity of capsules needed is less than 50, therefore the price will be less than $30, since they cost $30 per 50 caps, but only 12 are needed. Set up a ratio/proportion and say to your self out loud or in your head as you write the equation: If 50 Capsules cost $30, then how much will 12 capsules cost? 50 caps……………12 caps -------….…=………------- $30 ……………………..$X Cross multiply: 30 x 12 ---------- = X$ = $ 7.20 50 Second the amount of ointment base that you need is 120 grams. It costs $7.50 per pound. So you must havememorized the metric equivalent to English pound. That is 1 KG = 1000 gram = 2.2 lbs Therefore 1000gm = 2.2 lbs Now set up a ratio/proportion: Say to yourself or out loud: If 1000gm is 2.2 lbs then how many grams is 1 pound? 1000gm…………..Xgm ------...=…----- 2.2 lbs………..1 lbs Cross Multiply: 1000 x 1 / 2.2 = 454.55 grams (same as one large box of raisins – the one with the lady on it!) Now if the cost is $7.50 per pound then this means the cost is $7.50 per 454.55 grams!!! But you ONLY need 120 grams of ointment! So set up another r/p: If 454.55 grams ( 1 lb) costs $7.50 then how much will 120 grams cost? 454.55 grams……………..120 grams ------------………=………---------- $7.50……………………………………..X$ Cross multiply: 7.50 x 120 / 454.55 = X$ $1.98 Therefore we shall add up the costs: Cost of 12 capsules: $7.20 Cost of 1b ointment: $1.98 Cost of Dispensing Fee: $ 5.00 Total cost = $14.18 Cost of the look on your face and the squeal that you will make when you find this problem easy to do after practice: PRICELESS!!!! I hope this has helped you. Please give me some feedback as to what you need to understand better.
