NUR 2474 EXAM 2: PHARMACOLOGY FOR
PROFESSIONAL NURSING EXAM 2
(Latest ) Rasmussen University
Comprehensive Examination - 100 Questions | Time Limit: 150 minutes | Total Points: 100
Instructions: This examination contains 100 multiple-choice questions across eight sections. Each question has one best answer.
Mark the correct choice by identifying the option labeled *[CORRECT]*. Rationales are provided for each question
referencing NUR 2474 curriculum, NCLEX-RN pharmacology standards, and evidence-based nursing practice. Cognitive
levels: 20% recall, 50% application, 30% analysis. Use critical thinking and the nursing process to select the best answer for
each clinical scenario.
Section 1: Pharmacokinetics & Pharmacodynamics Review
Q1: A patient receives an oral dose of a medication with a high first-pass effect. The nurse understands that,
compared with the same drug given intravenously, the oral dose will need to be:
A. Lower because oral absorption is complete and immediate
B. Higher because a portion of the drug is metabolized by the liver before reaching systemic circulation
*[CORRECT]*
C. Identical because bioavailability is unaffected by the route of administration
D. Lower because oral drugs bypass hepatic metabolism entirely
Correct Answer: B
Rationale: The first-pass effect describes hepatic metabolism of a drug absorbed from the gut before it reaches systemic
circulation, reducing bioavailability. Per NUR 2474 pharmacokinetics, oral doses of highly first-pass drugs (e.g., propranolol,
morphine, lidocaine) must be larger than IV doses to achieve the same therapeutic effect. Options A and D are incorrect
because the oral route is affected by first-pass metabolism. Option C is incorrect because bioavailability is route-dependent and
is reduced by the first-pass effect.
Q2: A drug has a half-life of 8 hours and is given once daily. Approximately how long will it take to reach steady
state, and how should the nurse explain this concept to the patient?
A. About 8 hours; steady state is achieved after one dose
B. About 16 hours; steady state is reached when peak equals trough
C. About 40 hours (roughly 5 half-lives); steady state is when the amount of drug absorbed equals the
amount eliminated per dosing interval *[CORRECT]*
D. About 80 hours; steady state is when the drug is fully cleared from the body
Correct Answer: C
Rationale: Steady state is reached after approximately 4-5 half-lives, so a drug with an 8-hour half-life reaches steady state
in roughly 40 hours. At steady state, the rate of drug administration equals the rate of elimination, producing stable peak and
trough levels. Option A confuses one half-life with steady state. Option B describes only two half-lives, which is insufficient.
Option D confuses steady state with complete elimination, which would require about 5 half-lives after the last dose.
Q3: A patient on long-term phenytoin therapy reports increasing therapeutic failure despite adherence. Lab
analysis reveals low serum albumin. The nurse recognizes that hypoalbuminemia most directly affects which
Comprehensive Examination - 100 Questions Page 1
,NUR 2474 Exam 2 - Pharmacology for Professional Nursing (2026/2027 Edition) Rasmussen University
pharmacokinetic phase of this highly protein-bound drug?
A. Absorption, because low albumin impairs gut transport
B. Metabolism, because low albumin induces hepatic enzymes
C. Distribution, because fewer binding sites increase the free (active) fraction of drug available to
receptors *[CORRECT]*
D. Excretion, because albumin is required for glomerular filtration
Correct Answer: C
Rationale: Phenytoin is highly protein-bound (~90%). In hypoalbuminemia, fewer albumin binding sites are available,
increasing the free (active) fraction of drug. This affects distribution and may increase toxicity risk even when the total drug
level appears therapeutic. NUR 2474 curriculum emphasizes that for highly protein-bound drugs, free drug levels (not total)
correlate with effect. Options A, B, and D incorrectly attribute the effect to other pharmacokinetic phases.
Q4: Which laboratory finding indicates that a drug with a narrow therapeutic index has reached a toxic level,
requiring the nurse to hold the next dose and notify the provider?
A. Peak level within the therapeutic range
B. Serum drug level above the upper therapeutic range with signs of toxicity *[CORRECT]*
C. Trough level at the lower end of therapeutic range
D. Half-life value greater than 4 hours
Correct Answer: B
Rationale: A drug with a narrow therapeutic index (e.g., digoxin, lithium, phenytoin, warfarin, aminoglycosides) has a small
margin between therapeutic and toxic doses. A serum level above the upper therapeutic range accompanied by clinical toxicity
signs requires holding the dose and notifying the provider. NUR 2474 stresses monitoring of peak/trough levels for such drugs.
Options A and C describe therapeutic levels; option D confuses half-life (a kinetic property) with serum drug levels.
Q5: A nurse is teaching a patient about an agonist medication. Which statement by the patient indicates correct
understanding of the drug's mechanism?
A. "This drug blocks the receptor so my natural chemicals cannot bind to it."
B. "This drug binds to the receptor and activates it, producing a response similar to my body's natural
chemical." *[CORRECT]*
C. "This drug prevents the receptor from responding to any stimulus."
D. "This drug competes with my natural chemicals but produces no effect itself."
Correct Answer: B
Rationale: An agonist binds to a receptor and activates it, producing a biological response similar to the endogenous ligand.
NUR 2474 receptor theory states that agonists have affinity (bind) and intrinsic activity (activate). Option A describes an
antagonist. Option C describes a noncompetitive antagonist or channel blocker. Option D describes a partial agonist that
competes but produces limited effect — not a full agonist.
Q6: A patient taking a maintenance dose of digoxin 0.25 mg daily is to receive a loading dose initially. The nurse
explains the loading dose is given to:
A. Prevent adverse reactions to the drug
B. Rapidly achieve therapeutic steady-state serum levels without waiting 4-5 half-lives *[CORRECT]*
C. Reduce the total daily dose required for therapy
D. Enhance first-pass metabolism of the drug
Comprehensive Examination - 100 Questions Page 2
,NUR 2474 Exam 2 - Pharmacology for Professional Nursing (2026/2027 Edition) Rasmussen University
Correct Answer: B
Rationale: A loading dose is a higher initial dose used to rapidly fill the volume of distribution and achieve therapeutic plasma
concentrations, bypassing the 4-5 half-life wait for steady state. Per NUR 2474, loading doses are common for drugs with
long half-lives (digoxin, amiodarone, phenytoin). Option A is incorrect — loading doses increase, not decrease, toxicity risk.
Options C and D misrepresent the pharmacologic purpose of loading doses.
Q7: A patient develops a rash, wheezing, and hypotension within minutes after receiving penicillin. The nurse
recognizes this as which type of adverse drug reaction, and what is the priority action?
A. Idiosyncratic reaction; administer the next dose at a lower amount
B. Side effect; document and continue therapy
C. Allergic (immunologic) reaction; stop the drug, initiate emergency anaphylaxis protocol, and notify
the provider *[CORRECT]*
D. Toxicity reaction; give flumazenil as antidote
Correct Answer: C
Rationale: Rash, wheezing, and hypotension immediately following drug administration describe a Type I IgE-mediated
allergic reaction (anaphylaxis). NUR 2474 medication safety requires stopping the drug, implementing emergency response
(epinephrine, airway, IV fluids), and notifying the provider. Option A incorrectly characterizes an unpredictable genetically
based reaction as allergic. Option B minimizes a life-threatening reaction. Option D names an incorrect antidote (flumazenil
reverses benzodiazepines, not penicillin allergy).
Q8: Which patient scenario best demonstrates drug tolerance, requiring dose adjustment or rotation therapy?
A. A patient who develops hives after the first dose of an antibiotic
B. A patient on chronic opioids requiring progressively higher doses to achieve the same pain relief
*[CORRECT]*
C. A patient who experiences drowsiness with each antihistamine dose
D. A patient whose serum drug level is above the therapeutic range after one dose
Correct Answer: B
Rationale: Tolerance is a decreased pharmacologic response requiring increasing doses to achieve the same effect, commonly
seen with opioids, benzodiazepines, and nitrates. NUR 2474 distinguishes tolerance from dependence (withdrawal on
discontinuation) and addiction (behavioral compulsion). Option A is allergy. Option C is a predictable side effect. Option D
suggests toxicity or accumulation, not tolerance.
Q9: A drug's package insert reports it is 90% protein-bound. The patient is also taking warfarin, which is also
highly protein-bound. The nurse anticipates that combining these drugs will:
A. Reduce the action of both drugs because they cannot bind to receptors
B. Increase the free fraction of warfarin, raising the risk of bleeding *[CORRECT]*
C. Have no clinical effect because both drugs are still circulating
D. Increase the rate of glomerular filtration of both drugs
Correct Answer: B
Rationale: Highly protein-bound drugs compete for albumin binding sites. Displacement increases the free (active) fraction of
warfarin, transiently increasing anticoagulant effect and bleeding risk. NUR 2474 emphasizes that drug-drug interactions at
the protein-binding site are clinically significant for narrow-therapeutic-index drugs like warfarin, phenytoin, and digoxin.
Options A, C, and D misunderstand how displacement affects free drug concentration and receptor availability.

Q10: Which pharmacodynamic concept explains why two drugs with similar bioavailability and half-life may
require very different doses to produce the same clinical effect?
A. Bioavailability
B. First-pass effect
C. Potency (the dose required to produce a given effect) *[CORRECT]*
D. Steady state
Correct Answer: C
Rationale: Potency refers to the dose of a drug needed to produce a given effect — a more potent drug requires a smaller dose
to achieve the same response as a less potent one. Per NUR 2474 pharmacodynamics, potency is distinct from efficacy
(maximal effect a drug can produce). Drugs with similar bioavailability and half-life can differ markedly in potency. Option
A (bioavailability) and option B (first-pass effect) are pharmacokinetic concepts; option D (steady state) is also kinetic.
Section 2: Medication Safety & Administration
Q11: A nurse is preparing to administer medications to a patient. Which sequence best reflects the standard "rights
of medication administration" as taught in NUR 2474?
A. Right patient, right drug, right room, right time, right documentation
B. Right patient, right drug, right dose, right route, right time, right documentation, right reason, right
response *[CORRECT]*
C. Right patient, right drug, right dose, right route, right time
D. Right drug, right dose, right route, right documentation, right provider
Correct Answer: B
Rationale: The rights of medication administration have expanded beyond the original 5 rights (patient, drug, dose, route,
time) to include documentation, reason, and response, plus newer additions such as right education and right to refuse. NUR
2474 medication safety curriculum uses the 8-rights framework. Options A and D contain fabricated rights (right room, right
provider). Option C lists only the original 5 rights, which is incomplete.
Q12: Which medication is classified as high-alert by the Institute for Safe Medication Practices (ISMP), requiring
independent double-checks before administration?
A. Acetaminophen 500 mg oral tablet
B. Heparin IV infusion *[CORRECT]*
C. Metformin 500 mg oral tablet
D. Ondansetron 4 mg oral tablet
Correct Answer: B
Rationale: ISMP designates heparin (and other anticoagulants), insulin, opioids, concentrated electrolytes (KCl), and
chemotherapy as high-alert medications because they carry a heightened risk of significant harm when errors occur. NUR
2474 requires independent double-checks and careful monitoring for high-alert drugs. Options A, C, and D are not high-alert
and have wider safety margins in typical adult doses.
Q13: A physician orders "hydroxyzine 25 mg PO." The nurse pulls a vial labeled hydralazine 25 mg from the
automated dispensing cabinet. Which best describes this situation and the priority action?
A. No issue; both drugs have similar effects
