Module 1 Quiz
1. Phenytoin requires that a trough level be drawn. Peak and trough levels are done:
a. When the drug has a wide therapeutic range
b. When there is a high correlation between the dose and saturation of receptor site
c. When the drug will be administered for a short time only
d. To determine if a drug is in the therapeutic range
2. Drugs that have a significant first-pass effect:
a. Bypass the hepatic circulation
b. Are rapidly metabolized by the liver and may have little, if any, desired action
c. Are converted by the liver to more active and fat-soluble forms
d. Must be given by the enteral (oral) route only
3. Albuterol is an example an antagonist. An antagonist is a drug that combines with the receptor to stimulate the target organ.
a. True
b. False
4. The route of excretion of a volatile drug will likely be the:
a. Skin
b. Bile and feces
c. Kidneys
d. Lungs
5. Receptors are the component of a cell or organism that interacts with a drug and initiates the chain of events leading to the drug’s
effects. The receptor site for a drug is the specific binding region of the receptor macromolecule and has a relatively high and
selective affinity for the drug molecule. The interaction of a drug with its receptor is the fundamental event that initiates the action
of the
drug. Many drugs are classified based on their primary receptor affinity. Which of the following types of receptors are utilized by
alpha and beta adrenergic receptors?
1
,OBGYN 5750
a. Intracellular receptors
b. Gated Ion Channels
c. G-protein-coupled receptors
d. Enzyme-linked receptors

6. Metabolism is the process of converting a medication into a less, or more active form. These forms are also known as
metabolites. Metabolites of certain drugs can either enhance or inhibit other drugs they interact with. Which of the following
drugs enhances the metbolism of cyclosporine, digoxin, oral contraceptives and warfarin?
a. Phenobarbital
b. St. Johns Wart
c. Itraconazole
d. Amiodarone
7. The point in time on the drug concentration curve that indicates the first sign of a therapeutic effect is the:
a. Minimum adverse effect level
b. Onset of action
c. Therapeutic range
d. Peak of action
8. Drugs that are receptor agonists may demonstrate what property?
a. Inverse relationship between drug concentration and drug action
b. Desensitization or down-regulation with continuous use
c. Irreversible binding to the drug receptor site
d. Up-regulation with chronic use
9. The process for choosing an effective drug for a disorder includes:
a. Prescribing medications that are available as samples before writing a prescription
b. Consulting nationally recognized guidelines for disease management
c. Asking the patient what drug they think would work best for them
d. Following U.S. Drug Enforcement Administration guidelines for prescribing
10. The nurse practitioner (NP) chooses to give cephalexin every 8 hours based on knowledge of the drug’s:
a. Propensity to go to the target receptor
b. Safety and side effects
c. Biological half-life
d. Pharmacodynamics
