The 4 Musculoskeletal Conditions You Will Definitely See on Your FNP Boards

Introduction
Musculoskeletal complaints account for a massive percentage of primary care visits, which means they are heavily represented on both the AANP and ANCC FNP board exams. When studying orthopedics, it is easy to get bogged down in the sheer volume of special tests and anatomical structures. Instead of trying to memorize every orthopedic test in existence, focus on the high-yield presentations, hallmark physical exam findings, and first-line diagnostics that boards love to test. Let us break down the four core musculoskeletal topics you need to master before test day.
1. Rotator Cuff Tears vs. Impingement Syndrome
Shoulder pain is a board exam staple, and examiners love to test your ability to differentiate between rotator cuff tendinopathy/impingement and a full or partial rotator cuff tear.
- Impingement Syndrome & Tendinopathy: Typically seen in patients with repetitive overhead activity. Pain is worsened with overhead lifting. Expect positive Neer and Hawkins-Kennedy test results. Range of motion is usually preserved, though painful.
- Rotator Cuff Tears: Often presents with weakness in addition to pain. A patient with a supraspinatus tear will struggle with abduction and outward rotation. Look for a positive Drop Arm Test or Empty Can Test (Jobe test).
Board Tip: If a question describes an older adult who suffered a fall or heard a "pop" followed by severe shoulder weakness and an inability to lift the arm overhead, think rotator cuff tear. The imaging of choice to confirm is an MRI, though plain radiographs should be done first to rule out fracture or dislocation.
2. Knee Injuries: Meniscus vs. Ligaments
Knee complaints require you to connect the mechanism of injury to specific physical exam maneuvers.
- Meniscal Tears: Usually caused by a twisting motion while the foot is planted. Patients report joint line pain, locking, catching, or the knee "giving out." Check for a positive McMurray test or Apley grind test.
- Cruciate Ligament Tears (ACL/PCL): ACL tears usually involve a non-contact deceleration injury with a sudden pop and rapid joint effusion (hemarthrosis within hours). Look for a positive Anterior Drawer test and Lachman test (the most sensitive test for an ACL tear).
Clinical Pearl: Always perform the Lachman test when evaluating acute knee trauma with instability. It is more reliable and easier to perform in an acute setting than the anterior drawer test because the less-injured knee can be used easily for comparison.
3. Inflammatory vs. Non-Inflammatory Arthropathies
Board questions frequently test your ability to distinguish between osteoarthritis (OA) and rheumatoid arthritis (RA), as well as crystal-induced arthropathies like gout.
- Osteoarthritis (OA): Wear-and-tear arthritis that worsens with activity and improves with rest. Morning stiffness is brief (under 30 minutes). Look for Heberden's nodes (DIP joints) and Bouchard's nodes (PIP joints).
- Rheumatoid Arthritis (RA): A systemic, autoimmune inflammatory condition. Morning stiffness lasts longer than 1 hour. It classically spares the DIP joints and involves symmetrical swelling of the PIP and MCP joints.
- Gout: Caused by monosodium urate crystals. Acute, intensely painful monoarthritis, frequently affecting the first metatarsophalangeal joint (podagra). Joint aspiration (arthrocentesis) reveals needle-shaped, negatively birefringent crystals.
Board Tip: When you see a question describing joint fluid analysis, remember: gout is negative (needle-shaped, negative birefringent) and pseudogout is positive (rhomboid-shaped, positively birefringent calcium pyrophosphate crystals).
4. Overuse Syndromes: Plantar Fasciitis and Carpal Tunnel
Do not overlook common repetitive strain injuries that walk into the primary care clinic every day.
- Plantar Fasciitis: Characterized by heel pain that is worst with the very first steps in the morning or after a period of rest. Pain improves slightly with gentle walking but worsens toward the end of the day. Management includes stretching, supportive footwear, and night splints.
- Carpal Tunnel Syndrome: Compression of the median nerve causing numbness and tingling in the thumb, index, middle, and radial half of the ring finger. Look for positive Phalen's test (wrists flexed together for 60 seconds) and Tinel's sign (percussion over the median nerve).
You have worked incredibly hard to reach this point in your FNP journey. Trust your clinical intuition, focus on the core patterns, and remember that board exams are testing safe, competent entry-level practice. Take a deep breath—you are fully capable of crushing this exam.
