The 7 Content Areas of Part IV

7 min read·Updated September 1, 2026

The seven patient encounters aren't random — they're drawn from seven testable content areas, and each area has a signature set of presentations and red flags. Knowing what each one tends to throw at you turns a “surprise” case into a pattern you've already rehearsed.

Why organize your prep this way

You can't predict which specific case you'll get, but you can guarantee coverage: if you've drilled the common presentations and the can't-miss red flags for all seven areas, nothing is truly novel on exam day. Pair each area with the disposition question — treat, work up, or refer? — because that's where the case is scored (red flags & dispositions).

1. Musculoskeletal

Your home turf and the most common — mechanical spine and extremity complaints. The trap is anchoring on “it's musculoskeletal” and missing the case where it isn't. Screen for fracture risk, and don't let a benign-sounding backache hide a red flag.

2. Neurological

Radiculopathy, peripheral neuropathy, and the emergencies: cauda equina (saddle anesthesia, bowel/bladder change), progressive or bilateral deficits, and upper-motor-neuron signs. A clean neuro exam — reflexes, motor, sensory, pathologic signs — is what separates a disc from a disaster.

3. Cardiovascular / Pulmonary

The masqueraders. Chest or upper-back pain that's actually cardiac; a AAA presenting as back pain; DVT/PE. These are high-stakes referrals, and recognizing them is worth heavy points. If the story doesn't behave mechanically, think vascular.

4. Gastrointestinal

Visceral referral is the theme — thoracolumbar or shoulder pain from an abdominal source, or GI symptoms that reframe a “back” complaint. Ask about the abdomen when the mechanical story is thin.

5. Endocrine

Systemic disease with musculoskeletal echoes — diabetes and its neuropathy, thyroid dysfunction, and the metabolic contributors to bone health. Often a co-management or work-up disposition rather than a pure office treat.

6. Renal / Urological

Flank pain that isn't facet-driven — stones, infection, referred visceral pain. Fever, dysuria, or hematuria in the history should pull you off the mechanical track fast.

7. Malignant

The one you cannot miss. History of cancer, unexplained weight loss, night pain that wakes the patient, age > 50 with new non-mechanical pain. When these cluster, the disposition is work-up or referral — treating conservatively is the wrong answer even if the exam feels benign.

Study move: for each area, write a one-line “most likely” presentation and its three red flags. Seven areas, ~21 red flags — that compact map covers most of what the exam can surprise you with.

Turn coverage into reps

Once you've mapped the areas, rehearse a full timed encounter in each — history, focused exam, report of findings, and a 950-character note — so the pattern lives in your hands, not just your notes. See Part IV, Station by Station and the study plan.

Frequently asked

What content areas does Part IV cover?

Seven: musculoskeletal, neurological, cardiovascular/pulmonary, gastrointestinal, endocrine, renal/urological, and malignant.

Which content area is most common on Part IV?

Musculoskeletal presentations are the most common — but the exam deliberately includes cases from other areas (and masqueraders) to test whether you recognize when a complaint isn't mechanical.
