NURS 3365 Pharmacologic Principles EXAM (Latest
): Questions and Verified Answers | 100%
Correct | Grade A
1. What is Pharmacology? - CORRECT ANSWER The study of drugs and their
interaction with living systems
2. What is a drug? - CORRECT ANSWER A drug is any chemical substance
(including herbal supplements) other than those normally required (food/water)
which affects living systems by changing their structure or functions
3. Clinical Pharmacology - CORRECT ANSWER The study of drugs in humans
4. Subsections of Pharmacology - CORRECT ANSWER Pharmacokinetics,
Pharmacodynamics, Pharmaco-therapeutics , Pharmaco-genomics and genetics,
Pharmaco-economics, and Pharmaco-ethnography
5. Pharmacokinetics - CORRECT ANSWER What the body does to the drug
6. What are the four processes of pharmacokinetics? - CORRECT ANSWER
Absorption, distribution, metabolism, and elimination
7. Pharmacodynamics - CORRECT ANSWER What the drug does to the body;
The drug's mechanism of action
8. Pharmaco-genomics and genetics - CORRECT ANSWER How genetics affects
drug metabolism- personalized medicine
9. Pharmaco-economics - CORRECT ANSWER Study of the cost/ benefit of
drugs
10. Factors affecting adherence to drug therapy - CORRECT ANSWER Age,
education level, severity of illness, understanding of the importance of toxicity,
length and complexity of therapy, symptom abatement, cultural beliefs, side
effects, and cost
11. Liquid drug formulations - CORRECT ANSWER Solutions, syrups, and
suspensions; Liquid absorbed faster than a solid
12. What are the routes of admin for liquid formulation drugs? - CORRECT
ANSWER Enteral/Parenteral/ Topical
, 13. Solid drug formulations - CORRECT ANSWER Tablets, capsules, powders,
14. What are the routes of admin for solid formulation drugs? - CORRECT
ANSWER Enteral/Parenteral/ Topical/Transdermal/Inhaled
15. Do topical drugs have a local or systemic effect? - CORRECT ANSWER Local,
topical stays where you put it
16. Do transdermal drugs have a local or systemic effect? - CORRECT ANSWER
Systemic, transdermal is absorbed through the skin
17. Solution - CORRECT ANSWER Particles of the drug are well mixed and do not
settle out in fluid; Solution is homogeneous so each dose gives the same amount
of drug
18. Suspension - CORRECT ANSWER A mixture that contains drug particles that
settle in fluid - *must be shaken to evenly distribute drug so each dose is same*
19. Solid Drug Formulations - CORRECT ANSWER Powders, capsules, scored
tablet- *may be broken/crushed*, extended release tabs/caps (absorbed over
time- *do not crush or chew*), enteric coated tabs (absorbed slowly *do not crush
or chew*), creams/lotion, patches (some absorbed over hours/days/week)
20. Routes of Drug Administration that cause systemic effects - CORRECT
ANSWER Access the circulation; Enteral- through the GI tract, (for people who
can't take things by mouth we can still give meds via enteral/feeding tubes but
you can only give meds that are liquid/can be crushed and made into a liquid this
way), Parenteral- by injection, Transdermal Patches- slow absorption through the
skin to blood, Rectal- can be either because it has two blood supplies,
Sublingual/Buccal- mucosa to systemic blood stream, rapid absorption
21. Types of Injectables - CORRECT ANSWER Intramuscular - effect in-10-15
minutes, Subcutaneous- (SQ or SC) effect in 15-20 minutes, Intravenous- no
absorption required effect immediate, Intradermal- TB skin test, Intrathecal- into
subarachnoid space- very small doses, and Intra articular - into a joint space
22. Routes of administration that cause local effects - CORRECT ANSWER Stay
where they're applied; Inhalation- absorbed through nasal mucosa or airway
(systemic effects with inhaled anesthetic gases), Topical- eye, ear, skin, mucus
membrane application (can have systemic effects at higher than normal doses,
or with increased absorption due to damaged or irritated skin or heat), and
Rectal- can be either because it has two blood supplies
23. Rate of absorption - CORRECT ANSWER How fast the drug leaves the site of
administration and into the bloodstream
