Directions: Read each question carefully and select the ONE best answer from the four options (A through D).
For calculation questions, show your work and apply NUR 2407 rounding rules: IV pump rates are entered in
whole mL/hr, gravity drip rates are rounded to whole gtt/min, and doses below 1 mL are rounded to the
hundredth. Each question is followed by the correct answer and an evidence-based rationale for study review,
so cover the answer key and simulate a timed 120-minute testing session before checking your work.

SECTION 1
Pharmacokinetics and Pharmacodynamics
15 Questions | Absorption, Distribution, Metabolism, Excretion, Drug-Receptor Theory, Therapeutic Index
Questions 1-15
Q1. A nursing student is reviewing the four basic processes that describe what the body does to a
drug over time. Which sequence correctly represents the phases of pharmacokinetics?
A. Absorption, distribution, metabolism, excretion [CORRECT]
B. Distribution, absorption, excretion, metabolism
C. Metabolism, excretion, absorption, distribution
D. Absorption, metabolism, distribution, excretion
Correct Answer: A
Rationale: Pharmacokinetics is the study of what the body does to a drug and consists of four sequential
phases: absorption (movement into the bloodstream), distribution (transport to tissues and fluids),
metabolism (biotransformation, primarily hepatic), and excretion (elimination through renal, biliary,
pulmonary, and other routes). The remaining sequences rearrange these phases incorrectly, because
metabolism cannot precede absorption for a systemic drug and distribution requires prior entry into the
vascular system. NUR 2407 presents this framework as the foundation for understanding onset, peak, and
duration of drug action.
Q2. A client with stable angina is prescribed nitroglycerin 0.4 mg sublingual PRN for chest pain.
The client asks the nurse why the tablet is placed under the tongue instead of being swallowed.
Which response by the nurse is most accurate?
A. Sublingual administration allows the drug to bypass absorption entirely and enter cells
directly.
B. Sublingual absorption avoids first-pass hepatic metabolism, allowing rapid therapeutic
blood levels. [CORRECT]
C. Swallowing destroys the active ingredients of nitroglycerin immediately in the stomach.
D. The sublingual route eliminates all adverse effects of the medication.
Correct Answer: B
Rationale: Nitroglycerin undergoes an extensive first-pass effect and is nearly completely inactivated when
swallowed, because portal circulation carries it to the liver before it reaches the systemic circulation. The
sublingual route allows absorption directly into systemic circulation through the rich capillary network
under the tongue, producing onset within 1 to 3 minutes. Option A is incorrect because absorption still
occurs, option C misstates the mechanism as gastric destruction rather than hepatic metabolism, and option
D is false because adverse effects such as headache and hypotension still occur. This application of the
first-pass effect is a core NUR 2407 pharmacokinetic principle.

Q3. A client receiving warfarin therapy is newly prescribed sulfamethoxazole/trimethoprim, a
highly protein-bound antibiotic. The nurse should anticipate which effect of this drug
combination?
A. A decreased anticoagulant effect as warfarin is pushed out of the bloodstream into the
tissues
B. No interaction, because the two drugs act on entirely different receptor sites
C. An increased anticoagulant effect and bleeding risk as warfarin is displaced from plasma
proteins [CORRECT]
D. Enhanced protein binding of warfarin, requiring a higher maintenance dose
Correct Answer: C
Rationale: When two highly protein-bound drugs compete for albumin binding sites, the displaced drug is
released into the plasma as free, unbound, pharmacologically active drug. Displacement of warfarin raises
the free warfarin concentration, elevating the INR and increasing the risk of bleeding. Options A and D
reverse the actual physiology, and option B ignores one of the most clinically significant and heavily tested
protein-binding interactions. NUR 2407 and NCLEX-RN standards require nurses to anticipate drug
potentiation whenever highly bound medications are combined.
Q4. A client begins an oral antibiotic that has a half-life of 8 hours. The clinical pharmacist notes
that the drug will reach steady state in approximately 40 hours. The nurse understands that this
statement reflects which pharmacokinetic principle?
A. Steady state is reached after two half-lives for every oral medication.
B. A loading dose is always required before steady state can occur.
C. Steady state occurs only when a drug is given intravenously.
D. Steady state is achieved after approximately five half-lives of consistent dosing.
[CORRECT]
Correct Answer: D
Rationale: Steady state, the point at which the rate of drug administration equals the rate of elimination and
serum concentrations plateau, is reached after about five half-lives with a consistent dosing schedule, and 8
hours multiplied by 5 equals the stated 40 hours. Loading doses shorten the time to a therapeutic level but
do not change the time to true steady state, making option B incorrect. Options A and C misstate the
half-life relationship and the route requirement entirely. This concept is heavily emphasized in NUR 2407
because it determines when therapeutic drug monitoring results become clinically interpretable.

Q5. A client with new-onset atrial fibrillation is prescribed an initial loading dose of digoxin
followed by a smaller daily maintenance dose. When a nursing student asks why, the nurse
explains that the purpose of the loading dose is to:
A. Achieve therapeutic serum levels rapidly before maintenance dosing begins.
[CORRECT]
B. Reduce the risk of toxicity during the first 24 hours of therapy.
C. Determine whether the client has an allergy to digoxin.
D. Replace the need for ongoing renal function monitoring.
Correct Answer: A
Rationale: A loading dose, sometimes called a bolus dose, is a larger initial dose given to saturate body
tissues and bring the serum concentration into the therapeutic range quickly, which is critical for drugs such
as digoxin that have long half-lives and would otherwise require days to become effective. The maintenance
dose then replaces only the amount of drug eliminated between doses. Option B is wrong because a loading
dose transiently increases rather than decreases toxicity risk, option C describes an allergy challenge that
has no basis in practice, and option D is false because renal function monitoring remains essential. This
distinction is a recurring NUR 2407 examination item.
Q6. Which statement best defines the therapeutic range of a medication?
A. The range of doses that can be administered without any laboratory monitoring
B. The plasma concentration range in which a drug produces therapeutic effects without
serious toxicity [CORRECT]
C. The amount of an administered dose that reaches systemic circulation unchanged
D. The amount of time required for half of the drug to be eliminated from the body
Correct Answer: B
Rationale: The therapeutic range is the window between the minimum effective concentration and the
minimum toxic concentration, and dosing regimens are designed to keep plasma levels inside this window.
Option C actually defines bioavailability and option D defines half-life, so both are pharmacokinetic
distractors rather than the target concept. Option A is false because narrow-margin drugs such as digoxin,
phenytoin, lithium, and warfarin require serum monitoring precisely because their therapeutic ranges are
narrow. Correctly matching these definitions is a recall-level competency repeatedly tested in the NUR
2407 pharmacokinetics module.
