PRACTICE QUESTIONS AND ANSWERS | VERIFIED SOLUTIONS | UPDATED 2026
• This study guide contains 200 practice questions with verified answers and
EXPERT RATIONALE to help you master pharmacology concepts tested in Exam 1
— use it by attempting each question first before revealing the answer.
• Each question follows a consistent format with 5 options (A–E), a highlighted
correct answer, and a clear EXPERT RATIONALE to reinforce your understanding of
drug mechanisms, nursing implications, and patient safety.
1. A nurse is preparing to administer a medication. Which of the following
actions best demonstrates adherence to the "rights" of medication
administration?
A. Administering the medication based on the patient's verbal request
B. Checking the medication label once before administration
C. Skipping verification if the medication has been given before
D. Asking another nurse to verify without checking yourself
E. Verifying the right patient, drug, dose, route, and time before
administration
EXPERT RATIONALE: The rights of medication administration (right patient, drug, dose,
route, time, documentation, reason, response) are the foundation of safe drug delivery
and reduce medication errors.
,2. A patient is prescribed a medication with a narrow therapeutic index. What
does this mean for nursing care?
A. The drug has a wide margin between effective and toxic doses
B. The drug requires no monitoring once initiated
C. The drug can be safely doubled if the patient misses a dose
D. The drug has minimal side effects
E. The difference between the therapeutic dose and toxic dose is very
small, requiring close monitoring
EXPERT RATIONALE: Narrow therapeutic index drugs (e.g., digoxin, warfarin, lithium)
require frequent monitoring of drug levels and patient response because small dosage
changes can lead to toxicity.
3. Which phase of pharmacokinetics involves the movement of a drug from
the site of administration into the bloodstream?
A. Distribution
B. Metabolism
C. Excretion
D. Elimination
E. Absorption
EXPERT RATIONALE: Absorption is the process by which a drug moves from its site of
administration into the systemic circulation. Factors such as route of administration,
blood flow, and drug formulation affect absorption.
4. A nurse is caring for a patient with severe liver disease. Which
pharmacokinetic process is most likely to be affected?
A. Absorption
,B. Distribution
C. Excretion
D. Protein binding
E. Metabolism
EXPERT RATIONALE: The liver is the primary site of drug metabolism. In patients with
liver disease, drug metabolism is impaired, leading to prolonged drug action and
increased risk of toxicity.
5. A patient with chronic kidney disease is prescribed a renally excreted drug.
What is the priority nursing concern?
A. Decreased absorption of the drug
B. Increased first-pass effect
C. Reduced protein binding
D. Faster drug distribution
E. Drug accumulation leading to toxicity due to impaired excretion
EXPERT RATIONALE: The kidneys are responsible for excreting many drugs. In renal
impairment, drugs accumulate in the body, increasing the risk of toxicity. Dose
adjustments are often necessary.
6. What is the term for the concentration of drug in the plasma that produces
the desired therapeutic effect without causing toxicity?
A. Lethal dose
B. Loading dose
C. Minimum toxic concentration
D. Peak level
E. Therapeutic range (therapeutic window)
, EXPERT RATIONALE: The therapeutic range is the plasma drug concentration range that
produces the desired therapeutic effect. Below this range, the drug is ineffective; above it,
toxicity occurs.
7. Which route of drug administration bypasses the first-pass effect?
A. Oral
B. Rectal
C. Sublingual
D. Intravenous
E. Enteral
EXPERT RATIONALE: Intravenous administration delivers the drug directly into the
bloodstream, completely bypassing the first-pass effect (hepatic metabolism after GI
absorption). Sublingual also largely bypasses it but IV is complete.
8. A nurse is teaching a patient about a new medication. The patient asks
what "half-life" means. What is the best response?
A. The time it takes for the drug to reach peak concentration
B. The duration of the drug's therapeutic effect
C. The time needed for the body to absorb the drug
D. The interval between doses
E. The time it takes for the plasma concentration of the drug to decrease
by 50%
EXPERT RATIONALE: Half-life (t½) is the time required for the plasma concentration of a
drug to decrease by half. It helps determine dosing intervals and how long a drug stays
in the body.
