2026/2027 | Pharmacology Q&A | Nursing
1. Pharmacology is best defined as which of the following?
A) The study of human anatomy and physiological processes
B) The study of medications and their effects on living organisms
C) The study of nutrition and dietary supplements
D) The study of microorganisms and infectious diseases
Correct Answer: The study of medications and their effects on living organisms
Rationale: Pharmacology is the scientific study of drugs, encompassing their sources, properties,
actions, interactions, therapeutic uses, and adverse effects. It focuses specifically on how chemical
substances affect biological systems. The other options describe anatomy, nutrition, and microbiology
respectively, which are distinct disciplines. Therefore, the correct definition centers on medications
and their effects on living organisms.
2. A nurse is reviewing a medication order and notes the abbreviation "PO." Which route of
administration does this indicate?
A) Rectally
B) By mouth
C) Intravenously
D) Topically
Correct Answer: By mouth
Rationale: The abbreviation "PO" stands for "per os," which is Latin for "by mouth." This is the most
common route of medication administration and involves swallowing the medication for
gastrointestinal absorption. Rectal administration is abbreviated PR, intravenous is IV, and topical
refers to application to the skin or mucous membranes. Therefore, the correct interpretation is oral
administration.
3. Which term describes the study of what a drug does to the body?
A) Pharmacokinetics
B) Pharmacodynamics
C) Pharmaceutics
D) Pharmacognosy
Correct Answer: Pharmacodynamics
Rationale: Pharmacodynamics focuses on the physiological and biochemical effects of drugs on the
body and the mechanisms by which those effects occur. It examines drug-receptor interactions, dose-
response relationships, and therapeutic versus toxic effects. Pharmacokinetics, in contrast, describes
,what the body does to the drug. The other options refer to drug formulation and natural drug
sources. Therefore, pharmacodynamics is the correct term.
4. Which term describes what the body does to a drug?
A) Pharmacodynamics
B) Pharmacotherapy
C) Pharmacokinetics
D) Pharmacogenetics
Correct Answer: Pharmacokinetics
Rationale: Pharmacokinetics describes the movement of a drug through the body, encompassing four
key processes: absorption, distribution, metabolism, and excretion. It determines how quickly a drug
reaches its target site, how long it remains active, and how it is eliminated. Pharmacodynamics,
conversely, describes the drug's effects on the body. The other options refer to treatment approaches
and genetic influences on drug response.
5. Which four processes make up pharmacokinetics?
A) Absorption, distribution, metabolism, and excretion
B) Administration, binding, activation, and elimination
C) Potency, efficacy, tolerance, and toxicity
D) Digestion, filtration, secretion, and storage
Correct Answer: Absorption, distribution, metabolism, and excretion
Rationale: Pharmacokinetics is classically defined by the acronym ADME, representing absorption
(movement into the bloodstream), distribution (movement to tissues), metabolism (chemical
alteration, primarily in the liver), and excretion (elimination, primarily by the kidneys). These four
processes determine the concentration of drug at its site of action over time. The other options
describe pharmacodynamic concepts or unrelated physiological processes.
6. A nurse is explaining the drug development process to a patient. Approximately one in how
many potential drugs is ultimately approved by the US FDA?
A) 100
B) 1,000
C) 10,000
D) 100,000
Correct Answer: 10,000
Rationale: The drug development process is highly selective and costly, with only a small fraction of
compounds advancing from initial discovery to FDA approval. Research indicates that approximately
one in 10,000 potential drugs successfully completes all phases of testing and regulatory review. This
statistic illustrates the extensive preclinical and clinical evaluation required to demonstrate safety and
efficacy. The other options overestimate or underestimate this approval rate.
, 7. A research nurse is meeting with a patient who agrees to participate in a clinical trial. Which
member of the health care team has the responsibility to explain the study and respond to
the patient's questions?
A) Registered nurse
B) Pharmacist
C) Research associate
D) Health care provider
Correct Answer: Health care provider
Rationale: In clinical research, the principal investigator or a designated health care provider holds
the responsibility for obtaining informed consent, which includes explaining the study purpose,
procedures, risks, and benefits, and answering patient questions. While nurses and pharmacists may
reinforce education, the formal consent process is a provider responsibility. The research associate
typically handles data collection and administrative tasks rather than consent discussions.
8. A nurse is interviewing a patient enrolled in a Phase I clinical trial. Which patient statement
indicates an understanding of this trial phase?
A) "I am doing this to be sure this drug is safe."
B) "I am doing this to be sure this drug is effective."
C) "I hope this drug is better than the current treatment."
D) "I can be part of demonstrating a cure."
Correct Answer: "I am doing this to be sure this drug is safe."
Rationale: Phase I clinical trials are primarily designed to evaluate the safety, tolerability, and
pharmacokinetics of an investigational drug in a small number of healthy volunteers or patients. The
primary goal is to determine safe dosage ranges and identify adverse effects, not to establish efficacy.
Efficacy is assessed in Phase II and Phase III trials. Therefore, the patient's statement about ensuring
safety reflects an accurate understanding of Phase I.
9. Good Clinical Practice (GCP) is a helpful resource for nurses involved in research. GCP
provides standards in which of the following areas? (Select all that apply.)
A) Design
B) Monitoring and auditing
C) Recording and reporting
D) Outcomes evaluation
Correct Answer: Design
Rationale: Good Clinical Practice (GCP) is an international ethical and scientific quality standard for
designing, conducting, recording, and reporting clinical trials. It provides guidance on trial design,
monitoring, auditing, recording and reporting of data, and protection of trial subjects. While GCP
informs the overall conduct of research, the specific standards explicitly addressed include design,
, monitoring, auditing, and recording/reporting. Outcomes evaluation is a component of trial analysis
but is not one of the primary GCP standards categories.
10. Drugs may elicit different responses depending on individual client factors. Which of the
following are individual factors that can affect drug response? (Select all that apply.)
A) Age
B) Sex
C) Body mass
D) Health status
Correct Answer: Age
Rationale: Individual factors that influence drug response include age (especially extremes of age),
sex, body mass, health status, and genetics. These factors affect pharmacokinetic processes such as
absorption, distribution, metabolism, and excretion, as well as pharmacodynamic sensitivity. Age is a
critical factor because pediatric and geriatric patients often require adjusted dosages due to
differences in organ function and body composition. The other options are also valid factors but the
question asks for identification of these factors collectively.
11. A physician has prescribed a brand name drug for a patient. The patient tells the nurse that
the medication is too expensive. What is the best plan by the nurse?
A) Tell the patient to skip doses to make the medication last longer
B) Have the doctor prescribe the generic version
C) Advise the patient to purchase the medication from an online pharmacy
D) Suggest the patient borrow medication from a family member
Correct Answer: Have the doctor prescribe the generic version
Rationale: Generic drugs contain the same active ingredients as brand name drugs and are
therapeutically equivalent but are typically less expensive. The nurse should advocate for the patient
by contacting the prescriber to request a generic substitution when appropriate. Skipping doses,
using online pharmacies of uncertain quality, or borrowing medication are unsafe practices that can
lead to treatment failure or harm. Therefore, requesting a generic prescription is the most
appropriate nursing action.
12. A nurse is teaching a class for clients about over-the-counter (OTC) medications. How does
the nurse determine that education has been effective?
A) Clients state that OTC medications are always safe
B) Clients report they will read all labels carefully and call the physician with questions
C) Clients indicate they will only take OTC medications when prescribed
D) Clients say they will avoid all OTC medications
Correct Answer: Clients report they will read all labels carefully and call the physician with
questions
