Understanding Physical Exams: What to Expect & Why They Matter

Comprehensive Physical Examination: Components & Value

A physical exam is a systematic, hands-on assessment to evaluate health status, detect disease early, and establish a baseline.

Standard Components

1. History: Chief concern, HPI, PMH, PSH, FH, SH, medications, allergies, ROS.
2. Vital Signs: BP, HR, RR, Temp, SpO₂, BMI, pain score.
3. General Appearance: Distress, habitus, hygiene, affect, gait.
4. HEENT: Eyes (pupils, EOM, fundus), ears (otoscopy), nose, throat (Mallampati, tonsils), thyroid.
5. Neck: Lymph nodes, carotid bruits, JVP, ROM.
6. Chest/Lungs: Inspection, palpation, percussion, auscultation (breath sounds, adventitia).
7. Cardiovascular: PMI, heart sounds (S1, S2, S3, S4, murmurs, rubs), peripheral pulses, edema.
8. Abdomen: Inspection, auscultation (bowel sounds), percussion (tympany, organomegaly), palpation (tenderness, masses).
9. Musculoskeletal: ROM, strength, special tests (joint-specific), spine alignment.
10. Neurologic: CNs, motor, sensory, reflexes, coordination, gait, mental status (MoCA/MMSE if indicated).
11. Skin/Lymphatics: Inspect/palpate all nodes; lesions (ABCDE).
12. Genitourinary/Rectal: As indicated (hernia, prostate, pelvic, rectal).

Common Ancillary Tests (Age/Risk-Based)

• Lipid panel, CBC, CMP, HbA1c, TSH, UA
• ECG (baseline >40 or risk factors)
• Cancer screening: Mammogram, Pap/HPV, PSA (shared decision), colonoscopy/FIT, LDCT (smokers)
• Bone density (women ≥65, men ≥70 or risk)
• Immunizations review (CDC schedule)

Why Regular Physicals Matter

• Early detection of HTN, DM, dyslipidemia, cancer
• Vaccination updates
• Risk factor modification counseling
• Continuity of care & relationship building
• Baseline for future comparisons

Frequency: Annual for adults >40 or with chronic conditions; every 1–3 years for younger healthy adults. Individualize with your PCP.
