1. Discuss how grapefruit juice affects the metabolism of certain medications.
Grapefruit juice has no effect on drug metabolism.
Grapefruit juice inhibits enzymes that metabolize certain drugs,
leading to increased drug levels in the bloodstream.
Grapefruit juice enhances the absorption of all medications taken with
it.
Grapefruit juice only affects medications taken orally.
2. What is the definition of pH partitioning in pharmacology?
pH partitioning describes the interaction between drugs and their
receptors.
pH partitioning is the process of drug metabolism in the liver.
pH partitioning is the method of calculating drug dosages based on
patient weight.
pH partitioning refers to the phenomenon where the ionization of a
drug is influenced by the pH of the environment, affecting its
absorption and distribution.
3. What is the primary factor that influences the concentration of a drug at its
site of action?
Drug absorption
Drug metabolism
Patient adherence
, Genetic testing
4. A patient is taking Maalox for heartburn and consumes orange juice shortly
after. What potential effect could this have on their treatment?
Reduced effectiveness of the antacid
No effect on treatment
Increased heartburn relief
Enhanced absorption of the antacid
5. Discuss how ethnic ancestry can influence the efficacy of tamoxifen therapy
in patients.
All patients respond equally to tamoxifen regardless of ancestry.
Ethnic ancestry can affect drug metabolism and response, leading
to variations in tamoxifen efficacy among different populations.
Tamoxifen is only effective in patients of European ancestry.
Ethnic ancestry has no impact on drug efficacy or metabolism.
6. Patient given drug for the first time and develops shortness of breath. HR 76
bpm, RR 20, BP 120/70. Checks correct dose given and learns some patients
experience SOB. What is reported?
D. A side effect.
A. An allergic response.
B. An idiosyncratic effect.
C. An iatrogenic response.
7. Describe the role of drug transporters in the absorption and distribution of
medications.
Drug transporters only affect the elimination of drugs from the body.
, Drug transporters facilitate the movement of drugs across cell
membranes, influencing their absorption and distribution in the
body.
Drug transporters are responsible for the synthesis of drugs in the
liver.
Drug transporters break down medications into inactive metabolites.
8. Prior to prescribing medication, the provider has a responsibility to perform
which of the following?
A thorough history
An evaluation of data gathered
A formulation of diagnosis and differential lists
All of the above
9. Which following cytochrome participates in drug metabolism?
Cytochrome b
Cytochrome c
Cytochrome c1
Cytochrome aa3
Cytochrome P450
10. Describe the role of regulatory bodies in managing prescriptive authority for
healthcare professionals.
Regulatory bodies provide direct patient care in hospitals.
Regulatory bodies conduct clinical trials for new medications.
Regulatory bodies establish guidelines and standards for who can
prescribe medications and under what circumstances.
, Regulatory bodies only approve new drugs for market release.
11. What should a patient getting Flagyl be informed not to do?
Do not drink alcohol with it (severe vomiting)
Do not take with antacids (reduces efficacy)
Do not eat with it (reduces efficacy)
Do not lay down after taking (esophageal erosion)
12. What are the four basic pharmacokinetic processes involved in drug
handling by the body?
Absorption, Circulation, Metabolism, Excretion
Absorption, Distribution, Transformation, Excretion
Ingestion, Distribution, Metabolism, Elimination
Absorption, Distribution, Metabolism, Excretion
13. A patient receiving a subcutaneous injection is experiencing delayed drug
effects. Which factor could be contributing to this issue based on the
absorption characteristics of SQ drugs?
Reduced blood flow to the injection site
The drug's molecular weight is too high
The patient has a high metabolic rate
The injection was administered too quickly
14. The MedWatch Program was instituted to:
Assure generic drugs were safe prior to marketing
Identify prescribers who over prescribe scheduled drugs
Improve reporting of adverse drug events
