Unit 6: Musculoskeletal & Rheumatology
Q1. 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. Synovium
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. Tendons (C) and
Fascia (D) are nonarticular, supporting soft tissues .
Q2. 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. Articular
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 .
Q3. Which of the following signs or symptoms indicate an
inflammatory etiology to musculoskeletal pain?
A. Decreased C-reactive protein
B. Hyperalbuminemia
C. Morning stiffness
D. Weight gain
Correct ,,,answer,,,: C. Morning stiffness
Rationale: Morning stiffness lasting longer than 30 minutes is a
hallmark of inflammatory arthropathies (like Rheumatoid Arthritis). In
contrast, mechanical pain (osteoarthritis) tends to worsen with activity
and improve with rest, with stiffness typically lasting less than 15
minutes .
, Q4. The clinician is performing muscle strength testing. The patient
has complete range of motion but only when gravity is eliminated.
Which numeric grade of muscle strength should be assigned?
A. 1
B. 2
C. 3
D. 4
Correct ,,,answer,,,: B. 2
Rationale: The standard muscle strength grading scale is:
• 0: No contraction
• 1: Flicker/trace contraction
• 2: Full ROM with gravity eliminated
• 3: Full ROM against gravity only
• 4: Full ROM against some resistance
• 5: Full ROM against full resistance .
Q5. The clinician suspects that a client has patellar instability. The
client is seated with the quadriceps relaxed, the knee is extended,
and the patella is displaced laterally. The knee is then flexed to 30
degrees. If instability is present, the maneuver displaces the patella,
and the client perceives pain. This is known as:
A. Apprehension sign
B. Bulge sign
C. McMurray’s test
D. Lachman’s test
Correct ,,,answer,,,: A. Apprehension sign
Rationale: The Apprehension test is used specifically for patellar
instability. The patient experiences pain and the sensation that the
