Domain 1: Foundational Pharmacology Concepts (Q1-Q15)
Q1: A nursing student is reviewing the differences between pharmacokinetics and pharmacodynamics. Which of the
following statements correctly describes pharmacokinetics?
A. The study of how drug-receptor interactions produce therapeutic and toxic effects
B. The study of drug absorption, distribution, metabolism, and excretion [CORRECT]
C. The study of how drugs interact with each other when administered concurrently
D. The study of genetic variations that affect individual drug responses
Correct Answer: B
Rationale: Pharmacokinetics is the study of what the body does to the drug, encompassing the four processes of absorption, distribution,
metabolism, and excretion (ADME). Pharmacodynamics, in contrast, is the study of what the drug does to the body, including mechanisms of
action, drug-receptor interactions, and dose-response relationships. Drug-drug interactions and pharmacogenomics are related but distinct areas
of study. NR293 Pharmacology for Nursing Practice, Chamberlain University 2026/2027 curriculum emphasizes distinguishing
pharmacokinetics from pharmacodynamics as a foundational competency.
Q2: A nurse is reviewing medication orders and notes that a drug has three different names listed. Which of the
following correctly describes the generic name of a drug?
A. It describes the exact molecular structure of the drug
B. It is the proprietary name supplied by the pharmaceutical manufacturer
C. It identifies the drug within its pharmacological class and is not owned by any company [CORRECT]
D. It is assigned by the FDA and is the official name used in official compendia
Correct Answer: C
Rationale: The generic name identifies a drug within its pharmacological class and is not proprietary to any manufacturer. It is the
non-proprietary name that is universally recognized and used in prescribing. The chemical name describes the molecular structure. The trade
(brand) name is the proprietary name supplied by the pharmaceutical company. The official name is listed in the United States Pharmacopeia
(USP). NR293 emphasizes understanding drug nomenclature because generic names provide information about drug class, which aids in
predicting effects and interactions.
Q3: A nurse is administering a medication and explains to the nursing student that the drug has a high therapeutic
index. Which of the following is the best interpretation of this information?
A. The drug has a narrow margin between the effective dose and the toxic dose
B. The drug requires frequent serum level monitoring to ensure safety
C. The drug has a wide margin of safety between therapeutic and toxic concentrations [CORRECT]
D. The drug is metabolized slowly and has a long half-life
Correct Answer: C
Rationale: The therapeutic index (TI) is the ratio between the toxic dose and the therapeutic dose of a drug. A high therapeutic index indicates a
wide margin of safety, meaning the drug is relatively safe because there is a large difference between the dose that produces a therapeutic
effect and the dose that produces toxicity. A low therapeutic index indicates a narrow margin of safety, requiring close monitoring (e.g.,
digoxin, warfarin, lithium). Half-life and metabolism rate are pharmacokinetic properties, not measures of therapeutic safety. NR293
highlights the therapeutic index as a critical concept for assessing medication safety.

, Q4: A client is receiving morphine for pain management. The nurse explains that constipation is a common effect of
this medication. Which of the following terms best describes this effect?
A. Adverse drug reaction
B. Idiosyncratic reaction
C. Side effect [CORRECT]
D. Contraindication
Correct Answer: C
Rationale: A side effect is a common, milder, expected, and predictable effect that occurs at standard therapeutic doses. Constipation from
morphine is a classic side effect because opioids slow GI motility by acting on mu receptors in the enteric nervous system. An adverse drug
reaction is a more serious, undesirable, and potentially dangerous effect (e.g., respiratory depression from morphine). An idiosyncratic reaction
is an unusual or unexpected response unique to an individual. A contraindication is a medical condition in which a drug should not be
administered. NR293 emphasizes the distinction between side effects and adverse drug reactions as a core examination competency.
Q5: A nurse is preparing to administer a medication classified as Pregnancy Category X. Which of the following is
the most important nursing action?
A. Ensure the client has signed an informed consent acknowledging potential risks
B. Verify that the client is using an effective form of contraception [CORRECT]
C. Administer the medication with food to minimize gastrointestinal effects
D. Monitor the fetal heart rate continuously during administration
Correct Answer: B
Rationale: Pregnancy Category X drugs have demonstrated teratogenic effects (can cause birth defects) and the risks clearly outweigh any
possible benefits during pregnancy. The most important nursing action is to verify that the client is using effective contraception to prevent
pregnancy while taking the medication. These drugs are absolutely contraindicated in pregnant women. While informed consent and monitoring
are important, the priority is preventing fetal exposure. NR293 identifies Pregnancy Category X classification and teratogenicity as critical
safety knowledge for medication administration.
Q6: A nursing student asks the instructor about the mechanism of an agonist medication. Which of the following is
the best response by the instructor?
A. An agonist binds to a receptor and blocks it from being activated by other substances
B. An agonist binds to and activates a receptor to produce a biological response [CORRECT]
C. An agonist alters the receptor structure so that it no longer responds to natural neurotransmitters
D. An agonist partially activates a receptor while preventing full activation
Correct Answer: B
Rationale: An agonist is a medication that binds to and activates a receptor, mimicking the action of endogenous substances to produce a
biological response. Full agonists produce the maximum receptor response, while partial agonists produce a submaximal response. An
antagonist binds to a receptor and blocks or inhibits it without producing a response. NR293 emphasizes understanding receptor interactions
(agonist vs. antagonist) because this knowledge is fundamental to predicting drug effects, therapeutic applications, and potential adverse effects
across all drug classes.
Q7: A client is prescribed a drug for the prevention of deep vein thrombosis following hip replacement surgery. The
nurse identifies this as which type of drug therapy?
A. Empiric therapy
B. Prophylactic therapy [CORRECT]
C. Palliative therapy
D. Supportive therapy
Correct Answer: B
Rationale: Prophylactic therapy is used to prevent illness or complications before they occur. Administering anticoagulants (e.g., enoxaparin)
after hip replacement surgery to prevent DVT is a classic example. Empiric therapy treats illness based on clinical presentation before definitive
diagnostic results (e.g., starting antibiotics for suspected infection). Palliative therapy relieves symptoms in conditions that are not curable (e.g.,
morphine for cancer pain). Supportive therapy treats symptoms to allow the body to heal itself (e.g., IV fluids for dehydration). NR293
classifies these therapy types as essential pharmacological concepts for nursing practice.
