Introduction
This comprehensive final examination is designed to assess mastery of foundational and applied pharmacological
principles essential for safe, patient-centered nursing practice. Students will demonstrate knowledge of
pharmacokinetics, pharmacodynamics, medication safety protocols, drug classifications, and evidence-based
prescribing guidelines. Questions include multiple-choice, clinical scenario-based items, and critical thinking
applications that reflect real-world decision-making in acute and community settings. Emphasis is placed on
regulatory compliance, ethical considerations, adverse effect recognition, and patient education. Each item is
structured to evaluate readiness for clinical reasoning and professional accountability in medication
administration.
,SECTION ONE: QUESTIONS 1–100
Question 1
A nurse is preparing to administer a medication that is known to have a narrow therapeutic index. Which action
is most critical for safe administration?
A. Administer the drug with food to enhance absorption
B. Monitor serum drug levels regularly
C. Double the dose if a dose is missed
D. Switch to an extended-release formulation
🟢 B. Monitor serum drug levels regularly
🔴 RATIONALE: Drugs with a narrow therapeutic index have a small margin between therapeutic and toxic
doses. Regular monitoring of serum levels is essential to prevent toxicity.
Question 2
A patient reports that their blood pressure remains elevated despite taking lisinopril for four weeks. What is the
nurse’s best initial response?
A. Instruct the patient to double the dose immediately
B. Discontinue the medication and start a beta-blocker
C. Assess adherence to the prescribed regimen
D. Report the patient to the pharmacy for noncompliance
🟢 C. Assess adherence to the prescribed regimen
🔴 RATIONALE: Before altering therapy, the nurse must first assess whether the patient is actually taking the
medication as prescribed. Non-adherence is a common cause of treatment failure.
,Question 3
The nurse is educating a patient about warfarin. Which statement by the patient indicates a need for further
teaching?
A. “I will avoid eating large amounts of spinach and kale.”
B. “I can take ibuprofen for my headaches.”
C. “I will get my blood tested regularly as scheduled.”
D. “I should tell my dentist I am taking warfarin.”
🟢 B. “I can take ibuprofen for my headaches.”
🔴 RATIONALE: Ibuprofen (NSAIDs) increases bleeding risk when combined with warfarin due to antiplatelet
effects and GI irritation. The patient should use alternative analgesics like acetaminophen.
Question 4
A drug that acts as an agonist at a receptor will produce which effect?
A. Blocks the receptor and prevents a response
B. Enhances the breakdown of natural ligands
C. Activates the receptor and produces a response
D. Alters receptor structure permanently
🟢 C. Activates the receptor and produces a response
🔴 RATIONALE: An agonist binds to a receptor and mimics the effect of an endogenous neurotransmitter or
hormone, resulting in a biological response.
Question 5
A prescriber orders a loading dose of digoxin. What is the primary rationale for this order?
, A. To reduce the risk of toxicity
B. To achieve steady-state concentration rapidly
C. To prolong the elimination half-life
D. To decrease first-pass metabolism
🟢 B. To achieve steady-state concentration rapidly
🔴 RATIONALE: A loading dose rapidly achieves therapeutic drug levels, allowing immediate clinical effect
rather than waiting for steady state via multiple maintenance doses.
Question 6
Which patient statement regarding sublingual nitroglycerin requires immediate correction by the nurse?
A. “I will sit down before taking a tablet.”
B. “I can take up to three tablets five minutes apart.”
C. “I will swallow the tablet with a small sip of water.”
D. “I will call 911 if chest pain is not relieved after one tablet.”
🟢 C. “I will swallow the tablet with a small sip of water.”
🔴 RATIONALE: Sublingual nitroglycerin must be placed under the tongue and allowed to dissolve; swallowing
inactivates the drug via first-pass metabolism.
Question 7
A nurse administers naloxone to a patient with opioid overdose. What is the primary mechanism of this drug?
A. Inhibits opioid metabolism in the liver
B. Increases opioid excretion via the kidneys
