1 Pharmacy Technician Math Module

2 Calculate the Dosage Aisha is a pharmacy technician at a local hospital. She works part time to support her family and provide health insurance coverage for her family. She prefers to work evenings when her husband can assist her by watching their two children. Hi, my name is Aisha; I am a pharmacy technician.

3 Focus The focus of this math strand is for you to be able to figure out the amount of medication, in the proper form, to fill a prescription ordered by a doctor. In this math strand, you will be learning and reviewing the following math skills: 1) Applying medical abbreviations to math solutions 2) Using a formula to calculate dosage 3) Adding 4) Multiplying 5) Dividing 6) Sorting necessary and unnecessary information to solve a word problem 7) Noting key math words or phrases to solve math problems such as simplify an expression and per, as in milligrams per milliliter 8) Reading drug labels 9) Applying the standard formulas used in health care

4 Calculating Dosage On the evening shift, Aisha supports the nursing staff at the hospital by calculating medical dosages and providing the medicine in measured doses to the nursing staff. To do this, Aisha relies on some basic knowledge about medications.

5 Calculating Dosage The dose is located directly after the name of the medication. This is the individual dose that the doctor is ordering. The total medication order covers a certain period of time such as: take for 7 days, take for 10 days, or take daily. Look at the doctor’s prescriptions and consider the following questions: Phone DEA# Angela Truong, MD Pediatrician Pt. name Thi Tran Age Date May 1, 2008 Address: th Avenue, Anacortes, WA RX Ceclor 10 mL bid x 10 d Refill: X Generic and/or equivalent allowed Physician’s Signature Angela Truong Anacortes Pediatric Medical Office 23453 Mall Blvd. Anacortes, WA 98221

6 Questions 1) What is the drug name on the prescription? Click Here 2) What is the individual drug dosage? 3) How many times a day is this medication to be given? Ceclor 10 milliliters twice a day For 10 days

7 Listen Listen and read along as Aisha defines medical order and prescription. “Did you know that a medical order or medication order is a drug order written in a hospital, nursing home, or recovery center for a patient? A prescription is a drug order that is written in an office or clinic or for a client or patient being discharged. Licensed medical personnel like physicians, nurse practitioners, and other certified practitioners are allowed under state law to write medical orders and prescriptions. “

8 Task One: Reading the Doctor’s Prescription
A doctor writes prescriptions or drug orders for patients. Again, a prescription is a written medication order for a patient leaving a medical facility. A medical order is used in a hospital or care facility. For example, a patient in the hospital may have a change in medication or need to have an increase or decrease in the amount of medication. Both of these medical prescriptions follow a similar format and include the essential information that the pharmacy technician or other licensed health care workers will use to fill the order. Please note that the paper forms of prescriptions and medical orders do not all look the same; however, the information is the same. This information may be in a different location on the form.

9 Stop! Safety Alert: A pharmacy technician may fill the drug order and work under the supervision of the pharmacist. The pharmacist checks and verifies the accuracy of each filled prescription before handing it to the patient or client.

10 Format Look at the general format of a prescription. Do you look carefully at your prescription before you hand it to the pharmacist or pharmacy technician to fill? You should so that you know what medicine you are getting and the amount. You can also ask the pharmacist questions about what the doctor has prescribed. The job of a pharmacy technician requires careful reading. You need to read the prescription carefully to understand the medication ordered and then compare this drug order to the supply available on the pharmacy shelves. Phone # DEA# Thelma Cook, MD 2332 Medical Way Renton, WA 98056 Pt. Name: Age: Address: RX: Refill: Generic and/or equivalent allowed ___________________________________ Date Physician’s Signature

11 Format As a pharmacy technician, you need to read the prescription carefully; otherwise, you may not select the correct medicine to fill the bottle. This is especially true because many medications have similar names and, often times, a particular medication comes in several forms. The form of medication must match the route, or way, that the medication will be taken. For example, an elixir is a liquid and easily swallowed by a young child. An older adult may take the medication in tablet or capsule form. As a patient, you should check the number and type of medicine you get from the pharmacy to make sure that it matches what the doctor ordered.

12 Think About It! 1) What information is included on the prescription? 2) Why do you think that this information is important to the pharmacist? Advance to the next screen for the answers.

13 Answers 1) The prescription contains: a) The patient’s or client’s full name b) The date c) The drug name d) The doctor’s order for dosage amount (how much medication) e) The administration route (by mouth, IV, injection) f) The frequency with which the patient is to take the medication g) The duration, the number of days that the patient is to take the medication h) The quantity or amount that the pharmacist is to dispense i) A check-off or box allowing a substitute j) The physician’s signature k) The physician’s DEA number (United States Drug Enforcement Agency registration number) if the medication is a controlled substance such as morphine or codeine 2) To ensure that the correct medicine, amount, and type of medicine is filled for each prescription.

14 Answers The medical community requires that all prescriptions contain certain information. This is to avoid making medical errors. Again, the information is not required to be in the same format or placed in the same area on the prescription form. Thus, there is no single form for medical orders and prescriptions.

15 Contents of a Prescription
Here are the eleven items of a prescription: a) The patient’s or client’s full name b) The date c) The drug name d) The doctor’s order for dosage amount (how much medication) e) The administration route (by mouth, IV, injection) f) The frequency with which the patient is to take the medication g) The duration, the number of days that the patient is to take the medication h) The quantity or amount that the pharmacist is to dispense i) A check-off or box allowing a substitute j) The physician’s signature k) The physician’s DEA number (United States Drug Enforcement Agency registration number) if the medication is a controlled substance such as morphine or codeine

24 Tablets Listen and read along as Aisha discusses scored tablets. Did you know that only tablets that are scored may be split in half? What is a scored tablet? A tablet that is scored has a cut where it may be divided. It is important to know that only scored tablets can be divided to ensure an even distribution of medication. Enteric-coated tablets, those tablets with a special coating over the medicine, are not divided because they are coated with a special substance that allows them to dissolve in the intestines instead of the stomach. Dividing a tablet also impacts its absorption. Capsules (two-part soft tablets) and suppositories (medicine capsules inserted into the rectum) are never divided because the medicine needs to remain coated when it enters the body and even distribution of medication may be a problem. scored tablet

25 Practice Click Here to see the correct answers C D E B A
Match the terms. Click Here to see the correct answers C D E B A 1. Scored tablet A. dry weight of a medication 2. Capsule B. liquid or syrup 3. Suppository C. a tablet that is able to be divided. 4. Elixir D. a two-part tablet with soft outer shell 5. mg E. medication inserted rectally

26 Think About It! 1) Why do some drugs come in different forms? 2) How do you know what form it comes in? Advance to the next screen for the answers.

27 Answers 1) Drugs come in different forms because there are many different kinds of patients. For example, babies do not swallow tablets so there are injections, liquids, and suppositories. Adults can swallow tablets and capsules. Also, different administration routes have different absorption rates, or the medicine form determines how quickly it will become effective. For example, a tablet takes longer to work in the body than an injection. An injection goes into blood stream quicker. A tablet must be absorbed through the stomach and that takes time. 2)Read the prescription or medical order. Note that g or mg or mcg is a dry weight and so these are tablets, capsules or suppositories. Milliliters and units (a special unit of measure used in medicine) are volume or liquid measures, which could be elixirs or injections.

28 Task Two: Understanding the Parts of the Dosage Formula
The dosage formula has four parts. We use this formula to translate a doctor’s order so that a pharmacy technician can calculate an individual dose for a patient. Doctor’s Order Supply on Hand x quantity = dosage to be administered

29 Think About It! Why would a formula assist a pharmacy technician to calculate a drug dosage? Click Here Do you think that a formula can help sort out the parts of a word problem? A formula is an agreed upon method of calculating dosages in the same way so that the dosages are equivalent (or equal). Yes, because the quantities represented in the formula go in the same place in the math equation. Pharmacy technicians learn how to read the prescriptions and substitute the information into the dosage formula.

30 Dosage Formula Let’s look at the parts of the dosage formula.

31 Dosage Formula Let’s look more closely at the parts of the dosage formula. Information Where is it located? What is the format for the information? Doctor’s Order This information is on the prescription or in the medical chart of the patient. The information will be in grams(g), grains(gr), teaspoons (t), milliliter (mL)or other medication format. Supply on hand On the pharmacy shelves, in a locked area for controlled medications, in the refrigerator of the pharmacy. The information will be on the drug’s label. The information will be in grams (g), grains (gr), teaspoons (t), milliliter (mL)or other medication format. Quantity This is the information from the drug label and the information from the prescription. The information will be in grams (g), grains (gr), teaspoons (t), milliliter (mL) or other medication format.

32 Dosage Formula Another part of the prescription to know about is the medical terms used to detail the doctor’s order. To calculate an individual drug dosage, we use a formula. Patients have individual dosages and daily doses. The formula is used to calculate an individual or one-time dose. The daily dose has to do with the frequency of a dose. qd = every day every 8 hours bid = twice a day at hs = hour of sleep tid = three times a day prn = as needed qid = four times daily

33 Dosage Formula Note that time does not play a role in calculating the individual dose. The factors are the doctor’s order for an amount of drug, the form of the medication available in the pharmacy, and the form of the medication (tablet, capsule, mL).

34 Units of Measure Aisha is often asked to describe how much a gram, milligram, and a microgram weigh. She shows the clients this chart to show the relationship among these common metric units of measure. Kilogram Gram Milligram 2.2 pound pineapple a medium paperclip 60 grains of salt

35 Stop! In the metric system, the answers will be either whole numbers or decimals. For example: grams or 1.2 milliliters or 0.5 micrograms. No fractions are used in the metric system. Also, any decimal number that is not greater than 1 has a 0 in front. So the correct form is 0.8 mL instead of .8 mL.

36 Units of Measure Abbreviation Term Format/Explanation mg Milligram
Dry weight measure used in tablets mL Milliliter Liquid volume measure in liquids gr Grains Dry weight of medication g gram IM Intramuscular U Units A measure for penicillin and insulin q every d day Considered to be 24 hours h hour po orally By mouth

37 Practice Practice matching the medication forms. Click Here G H I J F
B E 1. qid A. by mouth or orally 2. hs B. liquid or syrup 3. bid C. every day 4. g D. three times a day 5. mg E. medication inserted rectally 6. po F. milligram 7. qd G. four times a day 8. gr H. at the hour of sleep; bedtime 9. U I. twice a day 10. tid J. gram 11. Elix. K. grain 12. Supp. L. Unit

38 Practice Use the formula to practice substituting the information from the prescription into the formula. dd hh x q = individual drug dose Doctor’s Order Supply on Hand x quantity = dosage to be administered

39 Stop! Safety Alert: The quantity is important to know because it leads the pharmacy technician to the correct form or unit of measure for a specific drug. In other words, if the quantity (q) is a tablet, the individual dose will be in tablets. If the quantity is in milliliters, the pharmacy technician knows that the medication is in liquid form. Including the quantity in the formula helps ensure proper form of the medication. Young children would take medication in a liquid form while adults may take a tablet or capsule.

40 Task Let’s put Aisha’s task together and see the medication vial and the prescription and learn how they are the tools of the pharmacy technician. Rx: Doctor Sheila Smith orders 30 mg of Augmentin for his patient. Aisha, a pharmacy technician, looks at the drug label and discovers that the medicine is supplied in 60 milligrams per tablet. RX 30 mg Augmentin Dr. Sheila Smith 4/6/08 60 mg

41 Practice Practice setting up the problems. Do not work the problems yet. 1) Order: mg Supply on hand: 250 mg per tablet Click Here 2) Order: mg Supply on hand: 2000 mg per scored tablet

42 Practice 3) Order: 1 g Supply on hand: .5 g per capsule Click Here 4) Order: 50 mg Supply on hand: 25mg per 5 mL 5) Order: 500 mg Supply on hand: 125mg per caplet

43 Task Three: Calculating the Dosage Formula
To calculate a doctor’s drug order (how much medication is needed for an individual dose), we use a formula. Review: Remember that the fraction bar means to divide. Doctor’s Order Supply on Hand x quantity = dosage to be administered

44 Methods There are two ways to look at calculating this formula. Method 1: Multiply d (doctor’s order) times q (format of the medicine on hand) then divide the result by h (supply on hand). The doctor orders 250 mg of a medication. Aisha has the medication in 125 mg per capsule in her pharmacy’s supplies. 250mg 125mg x 1 capsule = _________ a) 250 x 1 = 250 b)250 ÷ 125 = 2 Thus, the answer is 2 capsules, but this way of calculating the formula can be a bad habit to get into. If there weren’t a 1 in the quantity you could get an incorrect answer

45 Methods Method 2: Divide (the doctor’s order, the numerator, or top number) by h (the supply on hand, the denominator, or bottom number) then multiply by q (the format of the medicine on hand). The doctor orders 250 mg of a medication. Aisha has the medication in 125 mg per capsule in her pharmacy’s supplies. 250mg 125mg x 1 capsule = _________ a) 250÷125 = 2 b) 2 x 1 =2 Thus, the answer is 2 capsules.

46 Simplify One of the things to consider is the possibility of simplifying the expression before multiplying or dividing. For example, Aisha filled this prescription earlier in the day. The doctor order 100 milligrams of a medication. The drug was available in 25 milligrams per 5 milliliters. 100mg 25mg x 5 milliliters = _________ 100mg 100mg 25mg x 5 milliliters = 5 mg x 1milliliters = = 20 Thus, the answer is 20. Notice since 5 divides evenly into 25, Aisha simplifies the expression before multiplying or dividing.

47 Practice 5 mL 1.25 mL 20 mL 300mL 1.25 mL 1 mL
Practice simplifying expressions to be ready to work with Aisha. 1) 25mg 100 mg x 20 milliliters = Click Here 2) 5mg 32mg x 8 milliliters = Click Here 3) 500mg 50 mg x 2 milliliters = Click Here 4) 75mg 5mg x 20 milliliters = Click Here 5) 25mg 100mg x 5 milliliters = Click Here 6) 5mg 100mg x 20 milliliters = Click Here 5 mL 1.25 mL 20 mL 300mL 1.25 mL 1 mL

48 Practice Aisha needs to fill the following drug orders for the evening shift nurses. Assist her in the set up and the solutions of each medical order. 1) Ampillicin 500 mg p.o. qid X 5 d. Dosage available: 250 mg capsules. Click Here 2) Ordered Clondine 0.4 mg p.o. bid X 3 d. Dosage available: 0.1 mg tablets.

49 Practice 3) Prescribed: Tigan 200 mg IM q 8 h x 4 d for nausea. On hand: Single use vials 100mg/1mL. Click Here 4) Give: Digoxin elixir 150 mcg stat p.o. Dosage available: 50 mcg/mL. 5) Ordered: Codeine sulfate 60 mg p.o. q 4 h until further notice. Dosage available: 30 mg tablets.

50 Practice Read the prescription, and look at the medication bottle. Then use the dosage formula (d/h x q) to calculate the drug order. 1. Phone DEA# Bertha Bolls, MD Pt. Name Kumi Kaurker Age Date May 1, 2008 Address: Busy Ave E., Seattle, WA RX Lasix 40 mg p.o. q 12 h x 4 d Refill Generic and/or equivalent allowed Physician’s Signature Bertha Bolls, MD South Central Medical Center 34 Burlington Way N., Seattle, WA 98655

Name Elsa Bridges Age Date May 7, 2008 Address: 45 Riveria Way., Seattle, WA RX Ampicillintrihydrate 250 mg p.o. qid x 10 days Refill Generic and/or equivalent allowed Physician’s Signature Wing Hu Chi, MD Lake View Medical Center 54 Sealth Blvd. N., Seattle, WA 98655 Ampicillintrihydrate 125 mg in 5 mL of syrup

55 Answer Set up your formula: Click Here The patient will receive Click Here each dose. 10 milliliters or 10 mL

56 Task Four: Calculate daily doses and beyond
When Aisha is not filling individual medical orders, she often has a stack of other prescriptions to fill for her supervising pharmacist. She must prepare these for him to review for accuracy before they are bagged and binned for the customers to pick up at the pharmacy. To do this she must correctly interpret the prescriptions, duration, and/or the number of individual doses that the doctor has ordered. This relies on her skills in addition and multiplication as well as her ability to read the prescription.

57 Think About It! Why would a pharmacy technician need to be able to calculate a full prescription dosage? Click Here Do you think that multiplication is the most efficient means to solve this problem? To fill the complete prescriptions for clients. For example, clients do not go to the pharmacy on a daily basis. They go once to get the complete order filled. Yes, multiplication is usually faster than adding the number over and over.

58 Review Let’s review an earlier prescription:
Phone DEA# Pt. Name Mohamed Soma Age 32 Address: Ballard Ave E, Seattle RX Penicillin-G 2 million U IM qid x 7 d Refill Generic and/or equivalent allowed Physician’s Signature Aretha Arnold, MD Date May 2, 2008 Aretha Arnold, MD Infection Specialist North Central Medical Center 23 Antioch Way N, Seattle, WA The key to filling this prescription for the patient is to read the line: Penicillin-G 2 million U IM quid x 7 d.

59 Review Penicillin-G 2 million U IM qid x 7 d. This translates to 2 million units 4 times a day x 7 days. So to figure out the daily dosage: a) 2 million units x 4 = 8 million units b) To figure out 7 days’ dosage, multiply 8 million units x 7 days. For 7 days’ supply, the pharmacy must have on hand 56 million units of Penicillin-G.

60 Practice Help Aisha calculate the daily and the total prescription by days. Advance to the next screen for the answers.
