 Answers and Explanations :
1. D
To find the number of grams for each ingredient when ordered in equal parts, divide
the total weight ordered by the number of ingredients. Since there are three
ingredients, you would divide the total by three: (240 g)/3=80 g. Although the
hydrocortisone cream has a percentage strength associated with it, it has no
relevance in this example.

2. B
Liver metabolism is responsible for changing most drugs to a less active form that is
more easily excreted by the kidneys.

3. C
The Material Safety Data Sheet (MSDS) for the hazardous drug should specify what
action should be taken during an accidental spillage.

4. D
The patient profile may change often; thus, any updates to address, medications,
physical condition, etc. should be noted each time the patient fills a prescription.

5. C
Use the following conversion factor in a proportion with the number of grains you
have: 1 gr = 65 mg. Using this formula: 1 gr/65 mg = 10 gr/X. Cross-multiply and
divide to solve for X: X = 650 mg.

6. D
Dispense as written (DAW) clearly means the prescriber wants the drug dispenses
exactly as written, without generic substitution.

7. A
SSRIs such as fluoxetine (Prozac) have replaced the older tricyclic antidepressants
(TCAs) due to their effectiveness and favorable safety profile.

8. C
Convert the patient’s weight in pounds to kilograms by dividing by a factor of 2.2:
125 lb/2.2 = 56.82 kg. Multiply the dose by the weight to get the number of
milligrams in each dose: 2 mg * 56.82 kg = 113.6 mg. Set up a proportion using the
concentration of the stock vial and the milligrams needed to find the milliliters
required for the dose: 5 mg/1 mL = 113.6 mg. Cross-multiply and divide to solve for X: X = 22.7 mL. The “every 8h” is irrelevant in this problem because the problem
only asked for a single dose, not the total daily dose.

9. B
Small-neck bottles permit slower pouring, which limits spillage.

10. D
Calcium channel blockers are not prescribed for thrombosis prevention:
anticoagulant or antiplatelet drugs are used for this purpose.

11. B
This scenario involves converting Roman numerals to Arabic and calculating days’
supply. In Roman numerals, X = 10 and C = 100. When the smaller number (X) is
placed before the larger number (C), the smaller number is subtracted from the
larger: 100 – 10 = 90 tablets. The physician has also written the variable dose in
lowercase Roman numerals: i = 1 and ii = 2. When calculating days’ supply using a
variable dose or variable frequency, always use the maximum quantities for each
with the following formula: quantity prescribed/(maximum dose * maximum
frequency), so 90 tabs/(2 * 3) = 15 days. This method ensures that a third-party
payer will not reject a claim because it was refilled too soon.

12. A
Killing all pathogens on a device or other object is called sterilization. This term is
sometimes used interchangeable with medical asepsis, though there are distinctions
between the two terms.

13. A
Use an alligation grid (see next page) and subtract diagonally to find number of parts
of each solution: 9.1 parts 23.4% and 13.4 parts 0.9%. Calculate the sum of both
parts: 9.1 13.4 = 22.5 parts total. Divide the number of parts of 23.4% by the total
number of parts, then multiply by the volume you require: 9.1 / 22.5 * 250 mL = 101
mL. Repeat the same process for the 0.9%: 13.4 / 22.5 * 250 = 149 mL. Therefore,
the order requires 101 mL of 23.4% sodium chloride and 149 mL of 0.9% sodium
chloride solutions.

14. C
Buccal medications are tablets placed between the cheek and gum.

15. B
Use an alligation grid (see below) and subtract diagonally to find number of parts of
each solution: 20 parts dextrose 50% and 30 parts water. Calculate the sum of both
parts: 20 + 30 = 50 parts total. Divide the number of parts of dextrose 50% by the
total number of parts, then multiply by the volume you require: 20 / 50 * 1000 mL =
400 mL dextrose 50%. You may use a similar method to solve for the volume of
water required, but it is not necessary in this problem.

16. A
The IV route is used to deliver emergency medications because drugs will have the
fastest onset of action.

17. A
Intranasal medications often cause burning and stinging of the nasal mucosa;
however, this side effect tends to diminish with continued use. 18. C
Schedule II medications, such as morphine, are categorized as controlled
substances because they have a high potential for dependence and abuse.

19. B
Sig is the Latin word for signature, which means “write on the label”; directions for
taking the medication are included in this location.

20. C
Herbal therapies are products derived from plants that are available without a
prescription; saw palmetto is sometimes taken by people to treat an enlarged
prostate gland.

21. A
XR, LA, XT, and SR are abbreviations that indicate that the drug has an extended
duration of action.

22. C
Inventory is electronically monitored and a drug is reordered when the PAR level is

23. D
An accurate patient profile is obtain to correctly identify the patient, determine any
patient drug allergies, and to determine all medications the patient is taking.

24. A
The destruction of controlled substances is strictly controlled by the Drug
Enforcement Agency and is beyond the scope of practice of the pharmacy

25. B
The listing of all medications (both prescription and over-the-counter) assists the
pharmacist in looking for potential drug-drug interactions.

26. B
The purpose of inventory management is to ensure that the drugs most needed by
patients are readily available at a reasonable cost.

27. D
The Controlled Substances Act of 1970 (also called the Comprehensive Drug Abuse
Prevention and Control Act) established the DEA and the five schedules for
classifying abused drugs.

28. A
The abbreviation Rx, originally taken from the Latin word for recipe, now means

29. A
The FDA recalls drugs due to safety reasons: usually, the drug has been found to
have unacceptable adverse effects.

30. B
Prior to the Food, Drug, and Cosmetic Act of 1938, drugs could be marketed and
sold without being approved by the U.S. government.

31. A
The FDA Modernization Act was passed because the public and legislators were
concerned that the FDA was too slow in approving new drugs for AIDS and cancer.

32. B
HIPAA requires that all discussions regarding medical care be conducted in privacy.

33. A

within a reasonable time period.
