NUR 210 • PHARMACOLOGY PRACTICE SERIES
NUR 210 Pharmacology Exam 1 Practice Exam
2026–2027 • 110 MCQs • Foundations, pharmacokinetics, cardiovascular basics and safe administration
Emphasis: medication safety, pharmacologic principles, antihypertensives, introduction to drug classes and arithmetic.
Includes clinical application.
USE & SCOPE
Independent practice questions, not an official test, answer key, or course syllabus. NUR 210 varies by school. Dose
calculations are educational examples, not prescribing directions. Verify medication orders, current labeling, facility policies,
monitoring thresholds and patient-specific factors in actual care.
PRACTICE EXAM: QUESTIONS, ANSWERS & RATIONALES
1. Which action best prevents a wrong-patient medication error?
A. Check only the medication label
B. Use the room number as the identifier
C. Use two approved patient identifiers before administration
D. Ask a visitor to identify the patient
Correct answer: C. Use two approved patient identifiers before administration
Detailed rationale: Two independent identifiers, such as name and date of birth, reduce wrong-patient errors; room
numbers are not identifiers.
Why other options are incorrect: The remaining options are unsafe, unrelated, or inconsistent with the stated drug
mechanism/assessment.
2. A patient reports a severe prior reaction to a prescribed antibiotic. What is the nurse's priority?
A. Administer with food
B. Give the dose and document afterward
C. Hold the dose and clarify the allergy and order
D. Give half the dose
Correct answer: C. Hold the dose and clarify the allergy and order
Detailed rationale: A potentially serious allergy must be evaluated before exposure; dose reduction or food does not
prevent anaphylaxis.
Why other options are incorrect: The remaining options are unsafe, unrelated, or inconsistent with the stated drug
mechanism/assessment.
3. Which statement describes a high-alert medication?
A. It must be stored at room temperature
B. It is always contraindicated in older adults
C. It cannot be given intravenously
D. An error involving it may cause especially serious harm
Correct answer: D. An error involving it may cause especially serious harm
Detailed rationale: High-alert status refers to potential severity of harm from errors, not a universal route, age
restriction, or storage rule.
Why other options are incorrect: The remaining options are unsafe, unrelated, or inconsistent with the stated drug
mechanism/assessment.
4. The nurse finds that a medication's label differs from the order. What should happen next?
A. Ask the patient which is correct
B. Stop and resolve the discrepancy before administration
C. Document the discrepancy after giving it
D. Administer the labeled drug
Correct answer: B. Stop and resolve the discrepancy before administration
Detailed rationale: Unresolved drug, dose, or concentration discrepancies require verification before administration.

Why other options are incorrect: The remaining options are unsafe, unrelated, or inconsistent with the stated drug
mechanism/assessment.
5. Which method best confirms an initial patient's understanding of new medication instructions?
A. Ask whether they understand
B. Ask the patient to explain the plan in their own words
C. Ask a family member to sign the instructions
D. Provide only a printed sheet
Correct answer: B. Ask the patient to explain the plan in their own words
Detailed rationale: Teach-back reveals misunderstandings better than yes/no questioning or signatures.
Why other options are incorrect: The remaining options are unsafe, unrelated, or inconsistent with the stated drug
mechanism/assessment.
6. A patient refuses a prescribed medication. What should the nurse do?
A. Threaten discharge
B. Hide it in food
C. Record it as administered
D. Assess the reason, explain risks and benefits, and document and notify as appropriate
Correct answer: D. Assess the reason, explain risks and benefits, and document and notify as appropriate
Detailed rationale: An informed patient can refuse; the nurse assesses, educates, documents, and communicates
without coercion.
Why other options are incorrect: The remaining options are unsafe, unrelated, or inconsistent with the stated drug
mechanism/assessment.
7. Which route avoids gastrointestinal first-pass metabolism most directly?
A. Intravenous
B. Oral suspension
C. Oral tablet
D. Enteral feeding tube
Correct answer: A. Intravenous
Detailed rationale: IV medication enters systemic circulation without gastrointestinal absorption or hepatic first-pass
metabolism.
Why other options are incorrect: The remaining options are unsafe, unrelated, or inconsistent with the stated drug
mechanism/assessment.
8. Before giving a crushed tablet through a feeding tube, what must be verified?
A. That the formulation may be crushed and the route is appropriate
B. That the medication can be mixed with every other drug
C. That all extended-release tablets can be crushed
D. That flushing is unnecessary
Correct answer: A. That the formulation may be crushed and the route is appropriate
Detailed rationale: Extended-release and enteric-coated formulations often must not be crushed; compatibility and
flushing matter.
Why other options are incorrect: The remaining options are unsafe, unrelated, or inconsistent with the stated drug
mechanism/assessment.
9. A near miss is discovered before medication reaches the patient. What is the best response?
A. Discipline the patient
B. Ignore it because no harm occurred
C. Report it through the safety process and examine contributing factors
D. Alter the chart to conceal it
Correct answer: C. Report it through the safety process and examine contributing factors
Detailed rationale: Near misses offer important information for system-level prevention despite lack of injury.
Why other options are incorrect: The remaining options are unsafe, unrelated, or inconsistent with the stated drug
mechanism/assessment.

10. Which assessment most directly informs whether an adult can safely swallow an oral tablet?
A. Dominant hand
B. Hair color
C. Shoe size
D. Level of alertness and swallowing ability
Correct answer: D. Level of alertness and swallowing ability
Detailed rationale: An impaired swallow or level of consciousness raises aspiration risk and may require route
reassessment.
Why other options are incorrect: The remaining options are unsafe, unrelated, or inconsistent with the stated drug
mechanism/assessment.
11. The liver converts a medication into a less active compound. Which process is occurring?
A. Metabolism
B. Absorption
C. Distribution
D. Excretion
Correct answer: A. Metabolism
Detailed rationale: Biotransformation is metabolism; absorption is entry, distribution is movement, and excretion is
removal.
Why other options are incorrect: The remaining options are unsafe, unrelated, or inconsistent with the stated drug
mechanism/assessment.
12. A medication is eliminated primarily through the kidneys. Which laboratory measure is most relevant to dose
assessment?
A. Serum amylase
B. Hemoglobin A1c alone
C. Estimated glomerular filtration rate
D. Total cholesterol
Correct answer: C. Estimated glomerular filtration rate
Detailed rationale: Estimated filtration reflects kidney clearance better than unrelated tests; dose decisions also
depend on the drug and patient.
Why other options are incorrect: The remaining options are unsafe, unrelated, or inconsistent with the stated drug
mechanism/assessment.
13. A medication has a half-life of eight hours. Approximately what fraction remains 16 hours after one dose, assuming
first-order elimination?
A. 75%
B. 25%
C. 12.5%
D. 50%
Correct answer: B. 25%
Detailed rationale: Two half-lives pass in 16 hours: one-half becomes one-quarter.
Why other options are incorrect: The remaining options are unsafe, unrelated, or inconsistent with the stated drug
mechanism/assessment.
14. An antagonist occupies a receptor without activating it. What effect is expected?
A. It permanently destroys the receptor
B. It blocks or reduces an agonist's receptor response
C. It accelerates renal excretion of every drug
D. It always increases the agonist effect
Correct answer: B. It blocks or reduces an agonist's receptor response
Detailed rationale: A receptor antagonist inhibits signaling mediated by an agonist at that receptor.
Why other options are incorrect: The remaining options are unsafe, unrelated, or inconsistent with the stated drug
mechanism/assessment.
