Introduction
This comprehensive examination is designed to rigorously assess the foundational and applied pharmacology
knowledge essential for nursing practice at Galen College of Nursing. The assessment evaluates your ability to
synthesize pharmacodynamic and pharmacokinetic principles, apply the nursing process to medication
management, and demonstrate critical thinking in clinical scenarios. This exam moves beyond rote memorization,
challenging you to make sound clinical judgments, prioritize patient safety, and adhere to legal and ethical
standards. Through a combination of multiple-choice questions and complex, real-world scenarios, you will be
expected to analyze, interpret, and apply pharmacological concepts to ensure safe and effective patient care.
,Mastery of this content is crucial for the NCLEX-RN and for your future role as a competent and compassionate
nurse.
Section One: Questions 1–100
1. A nurse is preparing to administer a medication that is known to have a narrow therapeutic index. Which
of the following actions is most critical for the nurse to perform?
A. Administer the medication with food to enhance absorption.
B. Monitor the patient's serum drug levels regularly.
C. Assess the patient's skin for a rash.
D. Instruct the patient to avoid grapefruit juice.
🟢B
🔴 RATIONALE: A narrow therapeutic index indicates a small margin between therapeutic and toxic doses.
Regular monitoring of serum drug levels is essential to ensure the dose is within the safe and effective range,
preventing toxicity or therapeutic failure.
2. A client prescribed an ACE inhibitor for hypertension is also prescribed a potassium-sparing diuretic. What
is the nurse's priority assessment?
A. Serum sodium levels
B. Serum potassium levels
C. Blood urea nitrogen (BUN) and creatinine
D. Blood glucose levels
🟢B
🔴 RATIONALE: ACE inhibitors can cause potassium retention, and this effect is compounded when combined
,with a potassium-sparing diuretic. This combination significantly increases the risk of hyperkalemia, making
serum potassium monitoring the priority.
3. A nurse is providing discharge teaching to a patient taking warfarin. Which of the following statements by
the patient indicates an understanding of the teaching?
A. "I will take ibuprofen for minor aches and pains."
B. "I will increase my intake of leafy green vegetables."
C. "I will use a soft-bristled toothbrush."
D. "I will take the medication with a full glass of grapefruit juice."
🟢C
🔴 RATIONALE: Warfarin is an anticoagulant and increases the risk of bleeding. Using a soft-bristled toothbrush
minimizes the risk of gum bleeding. The other options are incorrect: ibuprofen increases bleeding risk, vitamin K
(in leafy greens) antagonizes warfarin, and grapefruit juice primarily affects CYP3A4, which has a minimal effect
on warfarin.
4. A patient is prescribed a beta-blocker, metoprolol, for heart failure. Which assessment finding would
indicate a therapeutic response to the medication?
A. Increased blood pressure
B. Decreased heart rate
C. Increased pulse oximetry
D. Decreased urine output
🟢B
🔴 RATIONALE: Metoprolol is a beta-1 selective blocker. A therapeutic response in heart failure includes a
decreased heart rate and improved cardiac output. Lowering the heart rate reduces myocardial oxygen demand
and improves filling time.
, 5. A nurse is administering a pain medication via the subcutaneous route. Which of the following needle
gauges is most appropriate for this administration?
A. 18-gauge
B. 20-gauge
C. 21-gauge
D. 25-gauge
🟢D
🔴 RATIONALE: A 25-gauge needle is standard for subcutaneous injections, as it is small and causes less tissue
trauma. The larger gauges (18, 20, 21) are typically used for intramuscular or large-volume medications.
6. The nurse is reviewing the prescriber's order for a patient with acute pain. The order reads: "Morphine 4-6
mg IV push q2h PRN pain." What is the most appropriate action by the nurse?
A. Clarify the order with the prescriber because it is a range order.
B. Administer 4 mg and assess the patient's response.
C. Administer 5 mg as a middle-ground dose.
D. Administer 6 mg because it is the maximum safe dose.
🟢A
🔴 RATIONALE: Range orders are not acceptable in most clinical settings and are considered unsafe. The nurse
should clarify the order with the prescriber to obtain a specific dose, frequency, and indication.
7. A patient is receiving IV vancomycin. The nurse notes the patient is flushed and complaining of a rash on
the neck and trunk. What is the most likely cause of this reaction?
A. Anaphylaxis
B. Seizures
