Introduction
The NUR 615 Final Exam assesses comprehensive advanced pharmacology knowledge required for safe
and effective prescribing in advanced practice nursing. This examination evaluates pharmacokinetic and
pharmacodynamic principles, drug metabolism pathways, pharmacogenomic considerations, and
therapeutic decision-making across major body systems. Questions are structured in multiple-choice and
scenario-based formats emphasizing clinical application, critical thinking, and prioritization in diverse
patient populations. Candidates must demonstrate competency in drug selection, dosing, monitoring,
adverse effect recognition, and integration of evidence-based guidelines into practice. The exam reflects
the complexity of contemporary pharmacotherapeutics and the clinical judgment required for
independent prescriptive authority.
SECTION ONE: QUESTIONS 1–100
Question 1
A patient with a CYP2C9 poor metabolizer phenotype is prescribed warfarin. Which clinical effect should
the advanced practice nurse anticipate?
A. Reduced anticoagulant effect requiring higher doses
B. Enhanced anticoagulant effect with increased bleeding risk
C. No change in warfarin response
D. Rapid elimination of warfarin with no therapeutic effect
B. Enhanced anticoagulant effect with increased bleeding risk
, RATIONALE: Warfarin is metabolized by CYP2C9. Poor metabolizers have reduced clearance, leading
to increased warfarin serum concentrations and enhanced anticoagulant effect. This significantly
increases bleeding risk. Genotype-guided dosing may be considered.
Question 2
A patient with heart failure is prescribed carvedilol. Which receptor activity characterizes this
medication?
A. Selective beta-1 blockade only
B. Non-selective beta blockade with alpha-1 blockade
C. Selective beta-2 agonist
D. Alpha-1 agonist only
B. Non-selective beta blockade with alpha-1 blockade
RATIONALE: Carvedilol is a non-selective beta-blocker with alpha-1 blocking activity. This
combination provides additional vasodilation, making it beneficial in heart failure. Beta-blockers reduce
mortality in heart failure when initiated at low doses and titrated slowly.
Question 3
A patient with type 2 diabetes is prescribed empagliflozin. Which mechanism of action characterizes this
medication?
A. Increases insulin secretion
B. Inhibits sodium-glucose cotransporter 2 in the kidney
C. Decreases hepatic glucose production
D. Blocks glucose absorption in the intestine
B. Inhibits sodium-glucose cotransporter 2 in the kidney
RATIONALE: Empagliflozin is an SGLT2 inhibitor that reduces renal glucose reabsorption, promoting
urinary glucose excretion. It also provides cardiovascular and renal benefits independent of glucose
lowering. Adverse effects include genital mycotic infections and euglycemic diabetic ketoacidosis.
Question 4
A patient is prescribed levothyroxine. Which administration instruction is most important?
A. Take with breakfast
B. Take on an empty stomach 30 to 60 minutes before breakfast
C. Take with calcium supplements
D. Take at bedtime with food
B. Take on an empty stomach 30 to 60 minutes before breakfast
RATIONALE: Levothyroxine absorption is affected by food, calcium, iron, and antacids. It should be
taken on an empty stomach 30 to 60 minutes before breakfast for optimal absorption. Consistent timing
is essential for stable thyroid hormone levels.
,Question 5
A patient receiving vancomycin develops flushing, rash, and hypotension during infusion. Which
condition should the nurse suspect?
A. Anaphylaxis
B. Vancomycin infusion reaction
C. Serum sickness
D. Stevens-Johnson syndrome
B. Vancomycin infusion reaction
RATIONALE: Vancomycin infusion reaction, also known as red man syndrome, is caused by rapid
histamine release during infusion. It presents with flushing, rash, and hypotension. Slowing the infusion
rate and premedicating with antihistamines can prevent recurrence.
Question 6
Which medication is a direct oral anticoagulant that selectively inhibits factor Xa?
A. Warfarin
B. Apixaban
C. Dabigatran
D. Heparin
B. Apixaban
RATIONALE: Apixaban is a direct oral anticoagulant that selectively inhibits factor Xa. Dabigatran is a
direct thrombin inhibitor. Warfarin inhibits vitamin K-dependent clotting factors. Heparin enhances
antithrombin III activity.
Question 7
A patient with asthma is prescribed montelukast. Which mechanism of action characterizes this
medication?
A. Beta-2 agonist
B. Leukotriene receptor antagonist
C. Corticosteroid
D. Mast cell stabilizer
B. Leukotriene receptor antagonist
RATIONALE: Montelukast is a leukotriene receptor antagonist that blocks the effects of leukotrienes,
reducing bronchoconstriction and inflammation. It is used for asthma prophylaxis and exercise-induced
bronchospasm. It is not effective for acute bronchospasm.
Question 8
A patient is prescribed metoprolol succinate for heart failure. Which statement about this medication is
accurate?
, A. It is a short-acting beta-blocker
B. It is an extended-release formulation for once-daily dosing
C. It is a beta-2 selective agonist
D. It is contraindicated in heart failure
B. It is an extended-release formulation for once-daily dosing
RATIONALE: Metoprolol succinate is the extended-release formulation of metoprolol, allowing once-
daily dosing. It is a beta-1 selective blocker proven to reduce mortality in heart failure. Metoprolol
tartrate is the immediate-release formulation.
Question 9
A patient with an infection caused by methicillin-resistant Staphylococcus aureus requires oral therapy.
Which antibiotic is most appropriate?
A. Amoxicillin
B. Cephalexin
C. Linezolid
D. Azithromycin
C. Linezolid
RATIONALE: Linezolid is effective against MRSA and available in oral formulation with excellent
bioavailability. Amoxicillin, cephalexin, and azithromycin are not effective against MRSA. Linezolid is a
synthetic oxazolidinone that inhibits bacterial protein synthesis.
Question 10
A patient is prescribed spironolactone for heart failure. Which adverse effect requires monitoring?
A. Hyperkalemia
B. Hypokalemia
C. Hypernatremia
D. Hypocalcemia
A. Hyperkalemia
RATIONALE: Spironolactone is a potassium-sparing diuretic that blocks aldosterone receptors,
retaining potassium. Hyperkalemia is the most significant adverse effect, especially when combined with
ACE inhibitors or ARBs. Serum potassium and renal function require close monitoring.
Question 11
A patient with hypothyroidism is prescribed levothyroxine. Which medication interaction is most
clinically significant?
A. Calcium carbonate
B. Acetaminophen
