NR 293 - EXAM 1 PRACTICE QUESTIONS AND
ANSWERS FOR EXAM PREPARATION
>> Drug
- correct answer- Any chemical that affects the physiologic processes of a living organism
>> Pharmacology
- correct answer- The study or science of drugs
>> Chemical Name
- correct answer- Describes the drug's chemical composition and molecular structure (not usually
used in nursing)
>> Generic Name
- correct answer- Name given by the United States Adopted Names council. The universal name,
like ibuprofen or acetaminophen
>> Trade Name
- correct answer- AKA proprietary name. The drug has a registered trademark, use of the name is
restricted by the drug's patent owner. Ex is Motrin and Advil, they are both ibuprofen
>> Pharmaceutics
- correct answer- The study of how various drug forms influence the way in which the drug affects
the body.
Oral, rectal, transdermal, etc.
, Page 2 of 25
>> Pharmacodynamics
- correct answer- The study of what the drug does to the body. The mechanism of drug actions in
living tissues and drug-receptor relationships
>> Pharmacotherapeutics
- correct answer- The clinical use of drugs to prevent and treat disease. Defines principles of drug
actions- the cellular processes that change in response to the presence of drug molecules.
Drugs are organized into pharmacologic classes, like antihypertensives.
Ex: elderly taking baby aspirin to prevent strokes
>> Pharmacognosy
- correct answer- The study of natural drug sources, like plants, animals and minerals.
>> Pharmaceutic Properties
- correct answer- Different drug dosage forms have different properties. Dosage form determines
the rate of drug dissolution. Enteric-coated tablets protect patients from stomach irritation.
>> Fastest Route of Oral Drug Absorption
- correct answer- 1. Oral disintegration, buccal tabs, and oral soluble wafers
2. Liquids, elixirs, and syrups
3. Suspension solutions
4. Powders
5. Capsules
6. Tablets
7. Coated tablets
8. Enteric-coated tabletes

>> Pharmacokinetics
- correct answer- The study of what the body does to the drug. A drug's time to onset of action,
time to peak effect, and duration of action.
-Absorption, Distribution, Metabolism, Excretion
>> Pharmacokinetics: Absorption
- correct answer- Movement of a drug from its site of administration into the bloodstream for
distribution to the tissues.
>> Bioavailability
- correct answer- A measure of the extent of drug absorption for a given drug and route. Giving a
med through the IV, you will have 100% of the med in the bloodstream, none is lost.
>> First-Pass Effect
- correct answer- The initial metabolism in the liver of a drug absorbed from the GI tract before
the drug reaches systemic circulation. If you give a PO med, the GI system digests, liver
transforms, and then it reaches the bloodstream. Not 100% of the med reaches the
bloodstream, you lose some as it travels.
>> Enteral Route of Drug Administration
- correct answer- The drug is absorbed into the systemic circulation through the oral or gastric
mucosa or the small intestine. Types of enteral are oral, sublingual, buccal, and rectal.
>> Parenteral Route of Drug Administration
- correct answer- Though an IV, IM, subcutaneous, intradermal, intraarterial, intrathecal, and
intraarticular
>> Topical Route of Drug Administration
- correct answer- Skin, eyes, ears, nose, lungs, rectum, vagina
