Introduction
This NU 578 Unit 3 Final Exam for 2026/2027 reflects the standardized unit assessment used to
evaluate competency in advanced pharmacology principles for graduate nursing students at the
University of South Alabama. The exam measures knowledge of autonomic pharmacology,
cardiovascular agents, diuretics, pharmacokinetic applications, drug interactions, adverse effect
management, and scenario-based clinical decision-making essential for safe, effective prescribing
practice as an Advanced Practice Registered Nurse.
The examination consists of 50 multiple-choice questions. Total testing time is approximately 100
minutes in a computer-based proctored format. A passing score of 75-80% is typically required per
USA College of Nursing graduate program policy.
Exam Instructions
• Each question has four answer choices (A, B, C, D).
• Select the single best answer for each question.
• Correct answers are marked in bold green.
• Rationales are provided in italic font to explain the correct answer.
Examination Questions
1. Which receptor type mediates the classic 'fight or flight' response when stimulated by
epinephrine?
A. Alpha-1 adrenergic receptors
B. Beta-1 adrenergic receptors
C. Beta-2 adrenergic receptors
D. Muscarinic receptors
Correct Answer: C
Rationale: Beta-2 adrenergic receptors mediate bronchodilation, vasodilation in skeletal
muscle, and glycogenolysis—key components of the fight-or-flight response. Stimulation
produces relaxation of smooth muscle in the bronchi and blood vessels supplying skeletal
muscles.
2. A patient receiving an anticholinergic medication reports dry mouth, blurred vision,
and urinary retention. These effects are primarily due to blockade of which receptor
type?
A. Nicotinic receptors
B. Muscarinic receptors
C. Alpha-1 receptors
D. Beta-1 receptors
Correct Answer: B
