SECTION 1: Pharmacology Foundations & Safety (10 Questions)
Q1: A nurse is preparing to administer morning medications. According to the Six Rights
of Medication Administration, what should the nurse check FIRST before proceeding?
A. Right documentation
B. Right patient
C. Right route
D. Right time
Correct Answer: B
Rationale: Nursing Process: Assessment. The FIRST right is Right Patient - verify using
two patient identifiers (name and date of birth or medical record number) before any
other step. This is the critical safety checkpoint that prevents wrong-patient errors,
which can have fatal consequences. Safety Protocol: Check armband and ask patient to
state name/DOB - never assume identity. Sequence: Patient → Medication → Dose →
Route → Time → Documentation. Distractors A, C, and D are all important rights but
occur later in the sequence; skipping patient verification first violates Joint Commission
National Patient Safety Goals.
Q2: A patient is prescribed oral nitroglycerin. The nurse understands that this
medication undergoes significant "first-pass metabolism." What does this mean?
A. The medication is absorbed directly into the bloodstream
B. The medication is extensively metabolized by the liver before reaching systemic
circulation
C. The medication bypasses the gastrointestinal tract
D. The medication has a longer duration of action
,Correct Answer: B
Rationale: Pharmacokinetics: First-pass metabolism occurs when oral drugs are
absorbed from GI tract → portal circulation → liver → metabolized before reaching
systemic circulation. Nursing Implication: Oral nitroglycerin has <10% bioavailability due
to first-pass effect, requiring much higher oral doses than sublingual or transdermal
forms. Patient Education: Explain why sublingual nitroglycerin is placed under tongue
(bypasses liver) and why consistency in medication form is critical. Distractor A
describes IV administration, C describes parenteral routes, and D is incorrect as
first-pass typically shortens duration.
Q3: A nurse discovers an insulin vial and heparin vial stored next to each other in the
medication room. What is the priority nursing action?
A. Label the vials more clearly
B. Report as a look-alike/sound-alike (LASA) medication storage error
C. Move the vials to different shelves
D. Verify expiration dates on both vials
Correct Answer: B
Rationale: Nursing Process: Implementation. LASA medications like insulin (high-alert)
and heparin (high-alert) have contributed to fatal errors due to similar vial appearance.
Safety Protocol: The Institute for Safe Medication Practices (ISMP) mandates separate
storage locations and auxiliary labels. Priority Action: Report through institutional safety
reporting system to trigger system-wide review and policy implementation. Distractor C
is a temporary fix, A doesn't address root cause, and D is routine monitoring but not the
immediate safety priority. This prevents organizational learning.
Q4: A nurse is reviewing a patient's admission orders and notices duplicate
prescriptions for metoprolol from both the hospitalist and cardiologist. What is the most
appropriate nursing action?
A. Administer both doses as prescribed
B. Contact the prescribers to clarify and resolve the duplication
C. Give the higher dose to ensure therapeutic effect
D. Document the discrepancy and hold both medications
, Correct Answer: B
Rationale: Nursing Process: Implementation. Medication reconciliation requires
identifying and resolving discrepancies, including duplications, omissions, and
interactions. Safety Priority: Duplicate therapy can cause serious harm (bradycardia,
hypotension). Nursing Intervention: Immediately contact both prescribers to clarify
intent and obtain corrected order; document communication. Distractor A is unsafe and
violates right dose, C is independent prescribing, and D delays necessary therapy
without addressing the root problem.
Q5: A patient asks why the nurse must scan their wristband and the medication barcode
before administration. What is the best nursing response?
A. "It's hospital policy that we must follow"
B. "This double-check system ensures you receive the correct medication safely"
C. "It documents the time we gave your medication"
D. "We need to verify your insurance information"
Correct Answer: B
Rationale: Patient Education: Barcode medication administration (BCMA) is a
technology safeguard that verifies the Five/Six Rights at bedside. Nursing Explanation:
Emphasize patient safety benefit - prevents wrong medication, wrong patient, wrong
dose errors. Engagement: Involve patient in safety process, empowering them to speak
up. Distractor A is technically true but doesn't explain the rationale, C is secondary
benefit, and D is irrelevant and concerning. This builds a culture of safety and patient
partnership.
Q6: A nurse is administering a medication with a narrow therapeutic index. What is the
priority nursing assessment?
A. Check the patient's allergy history
B. Monitor for therapeutic drug levels and toxicity signs
C. Verify the patient's understanding of side effects
D. Assess for cultural preferences
Correct Answer: B
