Introduction
The purpose of this comprehensive exam is to evaluate the clinical proficiency and theoretical
knowledge of nursing students and professionals in the field of pharmacology. This assessment
evaluates essential skills, including the understanding of drug mechanisms, identification of
,adverse effects, and the execution of safe administration protocols. Utilizing a combination of
multiple-choice questions and scenario-based applications, the exam mirrors real-world clinical
challenges. Candidates must demonstrate critical thinking and professional decision-making to
ensure patient safety and therapeutic efficacy. Emphasis is placed on the nurse’s role in
monitoring therapeutic responses and educating patients within regulatory and ethical
frameworks.
SECTION ONE: QUESTIONS 1–100
1. A patient is prescribed a drug with a narrow therapeutic index. Which nursing action is
most important?
A. Administer the drug with food to prevent gastric upset.
B. Monitor the patient’s blood levels of the drug closely.
C. Teach the patient to take the medication once daily.
D. Monitor the patient’s intake and output.
🟢 B. Monitor the patient’s blood levels of the drug closely.
🔴 RATIONALE: Drugs with a narrow therapeutic index have a small margin of safety between
a therapeutic dose and a toxic dose; therefore, serum drug level monitoring is required to
prevent toxicity.
2. A nurse is preparing to administer an enteric-coated tablet to a patient who has difficulty
swallowing. Which action should the nurse take?
,A. Crush the tablet and mix it with applesauce.
B. Dissolve the tablet in warm water.
C. Contact the provider for an alternative liquid form.
D. Cut the tablet in half to make it smaller.
🟢 C. Contact the provider for an alternative liquid form.
🔴 RATIONALE: Enteric-coated medications are designed to dissolve in the small intestine.
Crushing or cutting them destroys the coating, leading to premature absorption or gastric
irritation.
3. Which pharmacokinetic process is most affected by a patient’s liver failure?
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
🟢 C. Metabolism
🔴 RATIONALE: The liver is the primary site for drug metabolism. Impaired liver function can
lead to decreased drug breakdown and increased risk of toxicity.
4. A patient is receiving gentamicin and complains of "ringing in the ears." What is the
nurse's priority action?
, A. Document the finding as a common side effect.
B. Decrease the next dose by half.
C. Withhold the dose and notify the healthcare provider.
D. Administer an antihistamine as ordered.
🟢 C. Withhold the dose and notify the healthcare provider.
🔴 RATIONALE: Ototoxicity, manifested by tinnitus or hearing loss, is a serious adverse effect
of aminoglycosides like gentamicin and requires immediate cessation of the drug.
5. When administering a sublingual medication, the nurse should instruct the patient to:
A. Chew the tablet thoroughly before swallowing.
B. Place the tablet under the tongue and let it dissolve.
C. Swallow the tablet with a full glass of water.
D. Place the tablet between the cheek and the gum.
🟢 B. Place the tablet under the tongue and let it dissolve.
🔴 RATIONALE: Sublingual medications are absorbed through the oral mucosa under the
tongue, bypassing the first-pass metabolism of the liver.
6. A nurse is teaching a patient about the use of a spacer with a metered-dose inhaler (MDI).
What is the primary benefit of the spacer?
A. It makes the inhaler easier to hold.
B. It increases the delivery of the medication to the lungs.
