INTRODUCTION
This comprehensive examination contains 50 original verified questions designed to reinforce
the official Purdue Global University MN 566 NP I - Introduction to Primary Care for the Nurse
Practitioner course objectives for actual exam readiness and clinical proficiency in
the 2026/2027 academic year. The questions span four core domains: Domain 1
Musculoskeletal & Rheumatology (Unit 6) , Domain 2 ENT, Eyes, and Dermatology (Unit
7) , Domain 3 Gastrointestinal, Renal, and Endocrine (Unit 8) , and Domain 4
Pharmacology, Diagnostic Reasoning, and Health Promotion. Each question is crafted to
test distinct sub-topics drawn from foundational nurse practitioner primary care methodology,
enabling advanced practice nursing students to demonstrate clinical mastery of acute and
chronic condition management, diagnostic reasoning, pharmacotherapeutics, and evidence-
based primary care across the lifespan.
DOMAIN 1: MUSCULOSKELETAL & RHEUMATOLOGY (UNIT 6)
Question 1
One of the initial steps in assessing patients with musculoskeletal complaints is to determine
whether the complaint is articular or nonarticular in origin. Which of the following is an example
of an articular structure?
A. Bone
B. Synovium
C. Tendons
D. Fascia
CorreCt Answer: B ✓
rAtionAle: Articular structures are those directly involved in the joint itself. The synovium is
the lining of the joint capsule and is a primary articular structure. Bone (A) can be periarticular
but is not the primary articular structure. Tendons (C) and fascia (D) are nonarticular supporting
soft tissues.
Question 2
You have detected the presence of crepitus on examination of a patient with a musculoskeletal
, complaint. Additionally, there is limited range of motion with both active and passive movement.
These findings suggest that the origin of the musculoskeletal complaint is:
A. Articular
B. Inflammatory
C. Nonarticular
D. A and B
CorreCt Answer: A ✓
rAtionAle: Crepitus combined with limited active and passive range of motion suggests a
mechanical problem within the joint space (articular), such as osteoarthritis or a loose body.
Inflammatory conditions usually present with swelling, heat, and pain but not necessarily
mechanical blocks to passive motion unless chronic changes have occurred.
Question 3
A 55-year-old patient presents with gradual onset of knee pain that worsens with activity and
improves with rest. On examination, you note bony enlargement of the joint and crepitus. There
is no joint warmth or erythema. Which diagnosis is most consistent with these findings?
A. Rheumatoid arthritis
B. Osteoarthritis
C. Gout
D. Septic arthritis
CorreCt Answer: B ✓
rAtionAle: Osteoarthritis is a degenerative joint disease characterized by gradual onset,
pain worsening with activity and improving with rest, bony enlargement (osteophytes), and
crepitus. Absence of warmth and erythema distinguishes it from inflammatory conditions like
rheumatoid arthritis (A), gout (C), and septic arthritis (D).
Question 4
A 45-year-old woman presents with symmetric joint pain and stiffness in her hands, wrists, and
knees that lasts for more than one hour in the morning. She also reports fatigue and low-grade
fever. Which laboratory finding would be most consistent with this presentation?
A. Elevated uric acid
B. Positive rheumatoid factor (RF)
C. Elevated alkaline phosphatase
D. Positive ANA
CorreCt Answer: B ✓
rAtionAle: Rheumatoid arthritis (RA) is characterized by symmetric inflammatory
polyarthritis with morning stiffness lasting > 30-60 minutes. A positive rheumatoid factor (RF) is
present in approximately 70-80% of patients with RA. Elevated uric acid (A) is associated with
