Walden University NURS-6521: Advanced Pharmacology –
Final Exam Study Guide (150+ Questions and answers with
rationals)
EXAM OVERVIEW
The NURS-6521 Advanced Pharmacology final exam typically
consists of a 100-question exam covering Learning
Resources from Weeks 7-11. The exam is usually timed (2 to
2.5 hours) and consists of multiple-choice or multiple-
selection questions.
The course applies the advanced principles of pharmacology,
including pharmacogenomics, pharmacokinetics, and
pharmacodynamics, by analysis of common drug classes
prescribed by advanced practice nurses across the life span.
Key Topics Covered:
• Pharmacokinetics & Pharmacodynamics
(Comprehensive Review)
• Autonomic Nervous System Drugs
• Cardiovascular & Renal Pharmacology
• Endocrine Pharmacology
, • Anti-Infective Agents (Antibiotics, Antivirals,
Antifungals)
• Central Nervous System Drugs (Antidepressants,
Antipsychotics, Anticonvulsants)
• Oncology & Immunopharmacology
• Special Populations (Pediatrics, Geriatrics, Pregnancy,
Renal/Hepatic Impairment)
• Legal & Ethical Prescribing
• Adverse Effects, Drug Interactions, & Patient Safety
PART 1: PHARMACOKINETICS & PHARMACODYNAMICS
(Questions 1-25)
Question 1
A 68-year-old patient with cirrhosis and hypoalbuminemia
is prescribed a highly protein-bound medication. The nurse
practitioner understands that the free (active) drug
concentration will be:
• A) Decreased due to increased protein binding capacity
• B) Increased due to reduced albumin available for
protein binding
, • C) Unchanged because protein binding does not affect
drug activity
• D) Decreased because the liver metabolizes the drug
more rapidly
• Answer: B
• Rationale: Hypoalbuminemia (low serum albumin)
reduces the number of protein-binding sites available
for highly protein-bound drugs (e.g., phenytoin,
warfarin, valproic acid). This results in a HIGHER
concentration of FREE (unbound) drug, which is the
pharmacologically active form.This increases the risk of
drug toxicity even at "normal" total drug levels.
Cirrhosis further complicates this by reducing hepatic
metabolism and drug clearance.
Question 2
Which of the following routes of administration bypasses
first-pass hepatic metabolism?
• A) Oral
• B) Sublingual
• C) Enteral via NG tube
, • D) Oral extended-release formulation
• Answer: B
• Rationale: First-pass metabolism occurs when orally
administered drugs are absorbed from the GI tract and
transported via the portal vein to the liver, where they
are partially metabolized before reaching systemic
circulation. Routes that bypass first-pass metabolism
include sublingual, buccal, intravenous, intramuscular,
subcutaneous, transdermal, and inhalation.Sublingual
administration drains directly into the superior vena
cava via the sublingual vein, completely bypassing the
liver.
Question 3
A medication has a half-life of 8 hours. How long will it take
to reach approximately 94% steady-state concentration
with consistent dosing?
• A) 8 hours
• B) 16 hours
• C) 24 hours
• D) 40 hours
