INTRODUCTION
This comprehensive assessment is designed to evaluate the candidate's mastery of pharmacological
principles essential for safe and effective practical nursing practice. It measures a deep understanding
of drug classifications, mechanisms of action, therapeutic uses, adverse effects, and critical nursing
interventions. The exam encompasses multiple-choice questions and clinical scenarios that challenge
the test-taker to apply theoretical knowledge to real-world patient care situations. Emphasis is placed
on clinical decision-making, prioritization, dosage calculation, patient education, and adherence to
legal and ethical standards. Success on this examination demonstrates readiness to manage
pharmacotherapy across diverse patient populations and healthcare settings.
SECTION ONE: QUESTIONS 1 – 100
1. A patient is prescribed a medication that is known to have a high first-pass effect. The nurse
understands that this effect primarily involves which process?
A. Rapid excretion of the drug by the kidneys
B. Metabolism of the drug in the liver before it reaches systemic circulation
C. Binding of the drug to plasma proteins
D. Absorption of the drug through the gastrointestinal mucosa
🟢 B. Metabolism of the drug in the liver before it reaches systemic circulation
🔴 Explanation: The first-pass effect refers to the rapid hepatic metabolism of an orally
administered drug, which reduces the amount of active drug that reaches systemic circulation. This
is a critical concept in pharmacokinetics. Option A describes excretion, C describes protein binding,
and D describes absorption, none of which define the first-pass effect.
2. A nurse is preparing to administer a scheduled dose of digoxin. The patient's apical pulse is 52
beats per minute. Which action should the nurse take?
,A. Administer the medication as ordered
B. Hold the medication and document the finding
C. Administer half the dose and reassess in one hour
D. Notify the healthcare provider immediately
🟢 D. Notify the healthcare provider immediately
🔴 Explanation: Digoxin has a narrow therapeutic index and can cause toxicity. The normal apical
pulse rate for an adult is 60-100 bpm. A pulse of 52 bpm is bradycardic and a potential sign of
digoxin toxicity. The nurse should withhold the medication and notify the healthcare provider.
Holding and documenting alone (B) is insufficient, as the provider must be notified.
3. A client with type 1 diabetes mellitus is prescribed insulin lispro. The nurse should instruct the
client to administer this insulin at which time?
A. 30 minutes before a meal
B. At the same time each day, regardless of meals
C. Immediately before a meal
D. 1 hour after a meal
🟢 C. Immediately before a meal
🔴 Explanation: Insulin lispro is a rapid-acting insulin analog with an onset of action of 15-30
minutes. It should be administered immediately before (or within 15 minutes of) a meal to match
the postprandial glucose rise. Option A (30 minutes before) is typical for regular insulin, not lispro.
4. A patient is receiving intravenous vancomycin for a severe infection. The nurse monitors the
patient for which of the following adverse effects?
A. Hepatotoxicity
B. Ototoxicity
C. Cardiotoxicity
D. Nephrotoxicity and Ototoxicity
🟢 D. Nephrotoxicity and Ototoxicity
🔴 Explanation: Vancomycin is known for its potential to cause both nephrotoxicity (kidney
damage) and ototoxicity (hearing loss). These are the most significant adverse effects, especially
when serum levels are high or the drug is infused too rapidly. Monitoring renal function and
hearing is essential.
5. A nurse is providing education to a patient who has been prescribed an ACE inhibitor. Which
statement indicates that the patient understands the teaching?
A. "I should stop taking this medication if I develop a persistent, dry cough."
B. "I can take this medication with potassium supplements to prevent weakness."
C. "I should report any swelling of my face or tongue to my provider immediately."
D. "This medication will increase my heart rate, so I should monitor my pulse."
🟢 C. "I should report any swelling of my face or tongue to my provider immediately."
🔴 Explanation: Angioedema (swelling of the face, tongue, or airways) is a serious, potentially life-
threatening adverse effect of ACE inhibitors. The patient should be instructed to report this
, immediately. A dry cough is a common side effect that warrants discussion but is not a reason to
stop the drug without provider advice. Potassium supplements should generally be avoided.
6. A client is prescribed 40 mg of furosemide (Lasix) orally twice daily. The medication is
available in 20 mg tablets. How many tablets should the nurse administer for the morning dose?
A. 1 tablet
B. 1.5 tablets
C. 2 tablets
D. 2.5 tablets
🟢 C. 2 tablets
🔴 Explanation: 40 mg / 20 mg per tablet = 2 tablets. The calculation is straightforward. Options A,
B, and D represent incorrect mathematical calculations.
7. The nurse is caring for a patient who is taking warfarin. The patient's INR is 5.0. The nurse
should anticipate which intervention?
A. Increasing the daily warfarin dose
B. Continuing the current dose and monitoring
C. Holding the next dose and administering vitamin K as ordered
D. Administering protamine sulfate
🟢 C. Holding the next dose and administering vitamin K as ordered
🔴 Explanation: The therapeutic INR range for warfarin is typically 2.0-3.0. An INR of 5.0 indicates a
high risk of bleeding. The standard intervention is to hold the drug and administer vitamin K
(phytonadione) to reverse the anticoagulant effect. Protamine sulfate is used for heparin reversal.
8. A patient who is experiencing severe pain is prescribed morphine sulfate 4 mg IV push. The
nurse knows that a major adverse effect to monitor for is:
A. Urinary retention
B. Hypertension
C. Tachypnea
D. Diarrhea
🟢 A. Urinary retention
🔴 Explanation: Morphine and other opioids can cause urinary retention due to increased bladder
sphincter tone and decreased detrusor muscle tone. They also cause respiratory depression (not
tachypnea), hypotension (not hypertension), and constipation (not diarrhea).
9. A patient with a history of seizures is prescribed phenytoin (Dilantin). The nurse should teach
the patient to perform which action to maintain oral health?
A. Use a hard-bristled toothbrush to prevent plaque buildup
B. Floss vigorously to prevent gingival bleeding
C. Practice frequent and meticulous oral hygiene
D. Avoid the use of mouthwash containing alcohol
🟢 C. Practice frequent and meticulous oral hygiene
