Advanced Health Assessment and Diagnostic Reasoning
Section 1: Musculoskeletal System Assessment
(Joints, Bones, Muscles, Range of Motion, and Gait)
Q1: A 55-year-old patient presents with unilateral knee swelling, warmth, and restricted range of motion
following a fall two days ago. During the musculoskeletal assessment, the advanced practice nurse notes
crepitus on passive flexion and extension. Which finding most accurately distinguishes this presentation
from osteoarthritis?
A. Bilateral joint involvement with morning stiffness lasting less than 30 minutes
B. Unilateral effusion with warmth and a history of acute trauma [CORRECT]
C. Prolonged morning stiffness greater than one hour with symmetric joint involvement
D. Hard bony enlargement of the distal interphalangeal joints without warmth
Correct Answer: B
Rationale: The combination of unilateral effusion, warmth, and acute trauma history is most consistent with traumatic joint
injury or hemarthrosis rather than osteoarthritis (OA). OA typically presents with bilateral involvement, bony crepitus, hard
osteophytes at the DIPs (Heberden nodes), and morning stiffness lasting less than 30 minutes. Prolonged morning stiffness
exceeding one hour with symmetric involvement is characteristic of rheumatoid arthritis, not the acute traumatic presentation
described. The advanced practice nurse must differentiate traumatic effusion from degenerative or inflammatory arthropathies
to guide appropriate diagnostic imaging and referral.
Q2: During a gait assessment of a 72-year-old patient, the advanced practice nurse observes a shuffling,
wide-based gait with short steps and reduced arm swing. The patient appears to have difficulty initiating
movement but maintains balance once walking. Which neurological structure is most likely implicated in
these findings?
A. Cerebellum
B. Vestibular apparatus
C. Basal ganglia [CORRECT]
D. Corticospinal tract
Correct Answer: C
Rationale: The shuffling, wide-based gait with difficulty initiating movement (festinating gait) and reduced arm swing is
characteristic of basal ganglia dysfunction, commonly seen in Parkinson disease. Cerebellar pathology would present with a
wide-based, ataxic gait but not shuffling or bradykinesia. Vestibular dysfunction typically causes veering or falling toward the
affected side with a positive Romberg test. Corticospinal tract lesions produce spastic hemiparesis with circumduction gait.
Recognizing these gait patterns is essential for accurate neurological localization and differential diagnosis in the advanced
health assessment.
Q3: A 45-year-old construction worker reports numbness and tingling in the thumb, index, and middle
fingers of his right hand that worsens at night. The advanced practice nurse performs Phalen test by
having the patient hold both wrists in palmar flexion for 60 seconds. The patient reports reproduction of
the tingling sensation. What is the pathophysiological mechanism underlying this positive finding?

, A. Compression of the ulnar nerve at the cubital tunnel
B. Compression of the median nerve within the carpal tunnel [CORRECT]
C. Inflammation of the extensor tendons at the lateral epicondyle
D. Cervical nerve root impingement at the C6-C7 level
Correct Answer: B
Rationale: Phalen test evaluates for carpal tunnel syndrome by maintaining wrist palmar flexion, which increases pressure
within the carpal tunnel and compresses the median nerve. The median nerve provides sensory innervation to the thumb, index,
and middle fingers (palmar surface), which matches the patient symptoms. Ulnar nerve compression at the cubital tunnel would
affect the ring and little fingers. Lateral epicondylitis (tennis elbow) causes lateral elbow pain rather than distal paresthesias.
Cervical radiculopathy at C6-C7 would typically present with weakness, reflex changes, and a positive Spurling test rather than a
positive Phalen test.
Q4: When performing a musculoskeletal assessment on an 80-year-old patient, the advanced practice
nurse notes a decrease in muscle bulk, reduced range of motion in multiple joints, and diminished deep
tendon reflexes. Which age-related change best explains these findings?
A. Increased bone density and osteophyte formation causing joint ankylosis
B. Sarcopenia combined with degenerative joint changes and peripheral neuropathy [CORRECT]
C. Hyperthyroidism-induced myopathy with accelerated bone turnover
D. Rheumatoid arthritis with pannus formation eroding articular cartilage
Correct Answer: B
Rationale: Sarcopenia, the age-related loss of skeletal muscle mass and strength, explains the decreased muscle bulk in this
geriatric patient. Degenerative joint changes (osteoarthritis) contribute to reduced range of motion. Diminished deep tendon
reflexes are associated with peripheral neuropathy, which is common in older adults due to conditions such as diabetes or
age-related nerve fiber loss. Increased bone density is not an age-related change; osteoporosis with decreased density is expected.
Hyperthyroidism and rheumatoid arthritis are pathological conditions, not normal age-related changes, and would present with
distinct clinical features beyond what is described.
Q5: A 30-year-old athlete presents with acute onset of right knee pain after pivoting during a basketball
game. The advanced practice nurse performs the Lachman test. Which technique is correct, and what
would a positive result indicate?
A. The patient flexes the knee to 90 degrees; the examiner pulls the tibia forward. A positive result indicates
posterior cruciate ligament (PCL) injury.
B. The patient flexes the knee to 20-30 degrees; the examiner stabilizes the femur and applies an anterior
force to the proximal tibia. A positive result indicates anterior cruciate ligament (ACL) tear. [CORRECT]
C. The knee is extended; the examiner applies valgus stress. A positive result indicates medial collateral ligament
(MCL) sprain.
D. The patient lies supine with the knee flexed 90 degrees; the examiner applies a distraction force. A positive
result indicates meniscal tear.
Correct Answer: B
Rationale: The Lachman test is the most sensitive clinical test for ACL integrity. The knee is positioned in 20-30 degrees of
flexion (not 90 degrees, which is the anterior drawer test position), the femur is stabilized with one hand, and an anterior force is
applied to the proximal tibia with the other. Increased anterior tibial translation without a firm endpoint indicates ACL
insufficiency. Option A describes the anterior drawer test (less sensitive than Lachman). Option C describes valgus stress testing
for MCL integrity. Option D describes McMurray test for meniscal injury. The advanced practice nurse must use precise
examination techniques to accurately differentiate ligamentous injuries for appropriate imaging and orthopedic referral.
Q6: During a musculoskeletal assessment, a patient is asked to resist the examiner attempting to push the
arm downward while the arm is abducted to 90 degrees. The patient is unable to maintain this position.
Which muscle strength grade should the nurse document according to the standard 0-5 scale?
Page 2
, A. Grade 2: Active movement with gravity eliminated
B. Grade 3: Active movement against gravity only [CORRECT]
C. Grade 4: Active movement against gravity and some resistance
D. Grade 1: Flicker or trace of contraction
Correct Answer: B
Rationale: If the patient can abduct the arm to 90 degrees against gravity but cannot resist additional downward force, this
represents Grade 3 strength on the 0-5 scale. Grade 3 is defined as active movement against gravity but not against applied
resistance. Grade 4 requires movement against moderate resistance. Grade 2 requires gravity-eliminated active movement. Grade
1 represents only a visible or palpable muscle contraction without joint movement. Accurate muscle strength grading is
fundamental for documenting neurological and musculoskeletal status, tracking disease progression, and guiding treatment
decisions in advanced practice nursing.
Q7: A 60-year-old patient with a long history of rheumatoid arthritis presents for a follow-up assessment.
The advanced practice nurse examines the hands and identifies ulnar deviation of the fingers at the
metacarpophalangeal joints with swan-neck deformities of multiple digits. Which pathophysiological
process is primarily responsible for these deformities?
A. Osteophyte formation and articular cartilage thinning at weight-bearing joints
B. Synovial pannus formation eroding joint capsules and supporting ligaments [CORRECT]
C. Deposition of monosodium urate crystals triggering acute inflammatory response
D. Calcium pyrophosphate crystal deposition in the articular cartilage
Correct Answer: B
Rationale: In rheumatoid arthritis, synovial inflammation leads to pannus (hypertrophied synovial tissue with granulation tissue)
that invades and erodes articular cartilage, subchondral bone, joint capsules, and supporting ligaments. This destruction of the
supporting structures around the MCP joints results in ulnar deviation of the fingers. Swan-neck deformities (PIP hyperextension
with DIP flexion) result from imbalance between flexor and extensor mechanisms caused by pannus erosion of tendons and
ligaments. Osteophytes are characteristic of osteoarthritis, not RA. Monosodium urate crystals cause gout, and calcium
pyrophosphate deposition causes pseudogout; neither produces the characteristic hand deformities of RA.
Q8: The advanced practice nurse is performing a spinal assessment on a 40-year-old patient with chronic
low back pain. When asking the patient to flex forward from the standing position, the nurse observes
that the lumbar lordosis remains flattened and the patient reports pain at approximately 30 degrees of
flexion. Which condition is most consistent with these findings?
A. Muscle strain of the erector spinae
B. Ankylosing spondylitis [CORRECT]
C. Acute herniated nucleus pulposus at L4-L5
D. Spinal stenosis with neurogenic claudication
Correct Answer: B
Rationale: Loss of normal lumbar lordosis and pain with limited forward flexion are hallmark findings of ankylosing
spondylitis, a chronic inflammatory condition affecting the axial skeleton. In the early stages, reduced range of motion and loss
of lumbar lordosis are key assessment findings. Muscle strain would not typically cause a permanent flattening of lordosis. An
acute herniated disc at L4-L5 would more likely present with radicular symptoms, positive straight leg raise, and specific
dermatomal distribution rather than global limitation of spinal mobility. Spinal stenosis typically presents with neurogenic
claudication (pain with walking that improves with sitting or spinal flexion), which is the opposite of what is described here.
Q9: A 25-year-old patient presents with a swollen, erythematous, and exquisitely tender first
metatarsophalangeal joint that began abruptly overnight. The patient reports similar episodes in the past.
During the assessment, which technique is most appropriate for the advanced practice nurse to evaluate
this acute presentation?

Q4: When performing a musculoskeletal assessment on an 80-year-old patient, the advanced practice
nurse notes a decrease in muscle bulk, reduced range of motion in multiple joints, and diminished deep
tendon reflexes. Which age-related change best explains these findings?
A. Increased bone density and osteophyte formation causing joint ankylosis
B. Sarcopenia combined with degenerative joint changes and peripheral neuropathy [CORRECT]
C. Hyperthyroidism-induced myopathy with accelerated bone turnover
