1 · Anus & Rectum Examination

Instructional Objectives

  1. Review the anatomy of the rectum.
  2. Discuss the proper clinical skills for a comprehensive examination of the rectum.
  3. Demonstrate the proper clinical skills for a comprehensive examination of the rectum.

Objective 1 — Anatomy of the rectum

The rectum is the terminal ~12 cm of the large intestine, continuous with the sigmoid colon proximally and the anal canal distally, and marked internally by the transverse rectal folds (valves of Houston). The anal canal (~3–4 cm) is divided by the dentate (pectinate) line — columnar/transitional mucosa above, squamous below — and is guarded by the internal anal sphincter (involuntary smooth muscle) and external anal sphincter (voluntary skeletal muscle). In males, the prostate is palpable through the anterior rectal wall.

1.1 History & Positioning

Key anorectal history: hematochezia (bloody stool), pain on defecation, and any anal/perianal lesions. The standard exam position is side-lying (left lateral), hips and knees partially flexed, patient appropriately draped throughout.

The exam proceeds in a fixed sequence: inspect the sacrococcygeal/perianal areas → inspect the anus → perform the DRE (digital rectal examination).

1.2 Inspection & DRE (digital rectal examination) Technique

On inspection, note lesions, ulcers, inflammation, rashes, excoriations, external skin breakdown, and any masses or tenderness — palpate any abnormal area found on inspection.

DRE (digital rectal examination) steps

  1. Lubricate a gloved index finger.
  2. Insert the fingertip into the anal canal.
  3. Ask the patient to squeeze the anal sphincter (assesses tone).
  4. Palpate the rectal surface circumferentially.

1.3 Abnormal Findings & Special Maneuvers

FindingNotes
HemorrhoidsCommon anorectal abnormality
Anal fissures / wartsCommon anorectal abnormality
Sphincter tightness or laxityAssessed via the squeeze maneuver during DRE (digital rectal examination)
Perianal abscessCommon anorectal abnormality
MalignancyCommon anorectal abnormality

Special maneuvers: a prostatic examination (palpating the prostate's posterior surface anteriorly during the DRE (digital rectal examination)) and a rectovaginal examination (performed in the lithotomy position).

2 · Male GU (genitourinary) & Prostate Examination

Instructional Objectives

  1. Review the anatomy of the male internal and external genitalia.
  2. Discuss the proper clinical skills for a comprehensive examination of the following: male genitalia; prostate; inguinal and femoral hernias.
  3. Demonstrate the proper clinical skills for a comprehensive examination of the following: male genitalia; prostate; inguinal and femoral hernias.

Objective 1 — Anatomy of the male genitalia

The external genitalia are the penis (root, body, and glans, covered by the prepuce unless circumcised) and the scrotum, which houses the testes, epididymides, and spermatic cords. Internally, each testis produces sperm that pass through the epididymis and vas deferens; the seminal vesicles, prostate, and bulbourethral glands add seminal fluid. The inguinal canal transmits the spermatic cord and is the site of indirect (through the deep inguinal ring) and direct (through the posterior wall / Hesselbach's triangle) inguinal hernias; femoral hernias pass below the inguinal ligament.

2.1 History & Patient Comfort

Key history: lower urinary tract symptoms, urinary incontinence, penile discharge/lesions, scrotal/testicular pain-swelling-lesions, erectile dysfunction, and painful/irregular/curved erections.

If a patient develops an erection during the exam, calmly explain it is a normal physiologic response, complete the exam, and remain composed. If a patient refuses the exam, discuss their reasons rather than proceeding.

Expose only the area being examined at any time (gown over the chest/abdomen, drape at mid-thigh), and always wear gloves. In younger patients, review sexual maturity rating to document findings accurately.

2.2 Physical Exam Technique

  1. Inspect the penis, urethral meatus, and scrotum.
  2. Palpate the shaft of the penis.
  3. Assess for groin hernias by inspection and palpation, both without and with Valsalva.
  4. Palpate the epididymis and each testis.
  5. Examine the spermatic cord.

2.3 Special Techniques & Prostate Cancer

ManeuverPurpose
Inguinal/femoral hernia evaluationInspection and palpation, with and without Valsalva
TransilluminationAssess scrotal contents (for example, hydrocele)
Testicular self-examinationPatient self-screening technique, taught during the visit
Prostate palpationPosterior surface, via the anterior rectal wall during DRE (digital rectal examination)
Prostate cancer is the most frequently diagnosed cancer in US men, rare before age 40, with higher incidence in African American men. Screening uses PSA (prostate-specific antigen).

3 · Abdominal Examination

Instructional Objectives

  1. Review the anatomy of the abdomen.
  2. Discuss the proper clinical skills for a comprehensive examination of the abdomen.
  3. Demonstrate the proper clinical skills for a comprehensive examination of the abdomen.

Objective 1 — Anatomy of the abdomen

The abdomen is described in four quadrants (RUQ, LUQ, RLQ, LLQ) by the midline and transumbilical plane, or in nine regions. Key organ locations: liver and gallbladder (RUQ); stomach, spleen, pancreatic tail (LUQ); appendix and cecum (RLQ); sigmoid colon (LLQ); with the aorta and umbilicus in the midline. The kidneys and pancreas are retroperitoneal. This organ map underlies the auscultation, percussion, and palpation findings below.

3.1 Exam Order & Inspection

The abdomen is the one exception to the usual body-region exam order: Inspection → Auscultation → Percussion → Palpation (IAPerPal). Auscultation comes before percussion/palpation specifically so bowel sounds aren't artificially altered.

Tips for a good exam: empty bladder, comfortable patient, warm hands/stethoscope, examine the painful area last ("one finger" localization), watch the patient's face, and trim nails.

Inspect for skin changes, the umbilicus, scars, striae, dilated veins, rashes/lesions, contour (flat, round, protuberant, scaphoid), symmetry, visible organs, peristalsis, and pulsations (a visible aortic pulsation in the epigastrium can be normal).

3.2 Auscultation

Use the diaphragm, listening in all 4 quadrants for at least one full minute if sounds seem absent. Normal bowel sounds are clicks and gurgles, 5–34/minute (borborygmi = prolonged hyperperistaltic gurgling). Document as absent, normoactive, hyperactive, or hypoactive.

FindingSignificance
Bruit (aorta, renal, iliac, femoral)Vascular turbulence — listen with the diaphragm over each
Friction rub (liver/spleen)Peritoneal surface inflammation of that organ
Venous hum (epigastrium/umbilicus)Portal-systemic collateral circulation (for example, hepatic cirrhosis)

3.3 Percussion

Tympany predominates over gas/hollow organs; dullness occurs over fluid, feces, or solid organs. Liver span: percuss the lower border of dullness starting below the umbilicus in the right MCL (midclavicular line) moving upward, and the upper border from the nipple line downward. Spleen: percuss Traube's space (left costal margin); a positive splenic percussion sign (a change from tympany to dullness with deep inspiration at the lowest left interspace, anterior axillary line) suggests splenomegaly.

3.4 Palpation

TechniqueKey points
Light palpation<1cm depth; tenderness, muscular resistance, superficial masses; painful area last
Deep palpationTwo-handed, 3–4cm depth, all 4 quadrants, watch the patient's face
Liver (bimanual)Left hand lifts right flank; right hand presses in/up below costal margin on inspiration
Liver (hooking)Stand facing patient's feet, hook fingers under right costal margin on inspiration
SpleenUsually not palpable; left hand wraps left flank, right hand presses below left costal margin on inspiration
Kidney (capture technique)Left hand lifts flank, right hand presses down at peak inspiration to "capture" the kidney; right kidney more often felt (lower than left)
CVA (costovertebral angle) tendernessPatient sits up; fist strikes palm placed over costovertebral angle
AortaNormal width ≤3.0 cm, assessed bimanually in patients >50
Abdominal wall mass versus intra-abdominal mass: have the patient tense the abdominal muscles (raise head/shoulders). A wall mass stays palpable; an intra-abdominal mass becomes obscured by the contraction.

4 · Lung & Thorax Examination

Instructional Objectives

  1. Review the anatomy of the thorax and lungs.
  2. Discuss the proper clinical skills for a comprehensive examination of the following: thorax; lungs.
  3. Demonstrate the proper clinical skills for a comprehensive examination of the following: thorax; lungs.

4.1 Anatomy & Landmarks

The angle of Louis (sternal angle) is a key landmark: it's continuous with the 2nd rib (used to count ribs/intercostal spaces), marks the tracheal bifurcation into the main bronchi, and corresponds to the upper border of the atria. The right lung has 3 lobes (upper, middle, lower); the left has 2 (upper, lower, with a lingular segment).

4.2 Inspection & Palpation

Inspect: shape/symmetry, A/P diameter, scoliosis/kyphosis/tracheal displacement, pectus deformities (excavatum/carinatum), skin (cyanosis), nail beds, breath odor, and respiratory rate/pattern.

Palpate: tenderness, pulsations/bulges/depression/crepitus, respiratory (chest) excursion, tactile fremitus, and tracheal position.

Chest expansion technique: place hands at the 10th rib level with fingers loosely grasping the rib cage and thumbs meeting at midline; have the patient inhale deeply and watch the thumbs separate symmetrically.

4.3 Percussion & Diaphragmatic Excursion

Percuss systematically, superior to inferior, comparing side to side at 4–5cm intervals. For diaphragmatic excursion: percuss down the scapular line on held exhalation to mark the diaphragm level, then again after a deep inhale-and-hold; the distance between marks is the excursion.

FindingNormal / abnormal
Diaphragmatic excursionNormal 3–5.5 cm (up to 7–8 cm if well-conditioned); may be higher on the right (liver)
Decreased excursionPleural effusion, atelectasis, emphysema, pain, ascites

4.4 Auscultation & Voice Sounds

SoundCharacteristics
VesicularInspiration > expiration, soft, low pitch (most of lung fields)
BronchovesicularInspiration = expiration, intermediate intensity
Bronchial/trachealExpiration > inspiration, loud, high pitch

Adventitious sounds: crackles (rales), rhonchi, wheezes, friction rubs. Voice transmission tests: bronchophony (louder "99"), egophony ("E" → "A"), whispered pectoriloquy (whispered words heard clearly) — all suggest consolidation.

5 · Skin, Hair & Nail Examination

Instructional Objectives

  1. Review the anatomical structures of the integumentary system.
  2. Discuss the proper clinical skills for a comprehensive examination of the following: skin; hair; nails.
  3. Demonstrate the proper clinical skills for a comprehensive examination of the following: skin; hair; nails.

5.1 Anatomy & Skin Color

Skin has 3 layers: epidermis (most superficial), dermis (glands, hair follicles, nerve terminals), and subcutaneous tissue. Skin color depends on melanin (brownish, genetics/sun-dependent), hemoglobin (bright red oxyhemoglobin versus darker bluish deoxyhemoglobin), carotene (yellow, subcutaneous fat), and bilirubin (yellow-brown, from heme breakdown).

Sebaceous glands are present everywhere except palms/soles. Eccrine sweat glands are widely distributed; apocrine glands are primarily axillary/groin. Vellus hair is fine/lightly pigmented ("peach fuzz"); terminal hair is coarse and pigmented.

5.2 History

Common/concerning symptoms: hair loss, rashes, growths, sores, lumps/bumps, dryness, itching, and changes (especially moles changing size/shape/color/sensation). Family history should include skin cancers and atopic conditions (eczema, asthma, allergies).

5.3 Examination Technique

StructureInspect forPalpate for
SkinColor, uniformity, thickness, symmetry, lesions, rashes, drynessMoisture, texture, temperature (dorsal hand), turgor, mobility
HairColor, distribution, quantityTexture
NailsPigmentation, length, symmetry, ridging/pitting, cleanlinessTexture, firmness, thickness, adherence to nail bed
Normal nail base angle (proximal nail fold to nail plate) is 160 degrees. The lunula is the white half-moon at the proximal nail bed.

Patients should be undressed and gowned open in back, with makeup/nail polish removed; only uncover the area being examined at a time, and recover with the gown when finished.

6 · Eye Examination

Instructional Objectives

  1. Review the anatomy of the eye.
  2. Identify anatomic landmarks of the eye during the ophthalmoscopic exam.
  3. Discuss the proper clinical skills for a comprehensive examination of the eye and surrounding structures.
  4. Demonstrate the proper clinical skills for a comprehensive examination of the eye and surrounding structures.

6.1 Anatomy & Extraocular Muscles

MuscleCN (cranial nerve)Action
Superior rectusIIIElevation
Inferior rectusIIIDepression
Medial rectusIIIAdduction
Lateral rectusVIAbduction
Superior obliqueIVIntorsion & depression
Inferior obliqueIIIExtorsion & elevation

6.2 Vision Testing

Always test visual acuity before any test that shines light directly into the eye. Acuity is recorded as two numbers: distance from chart / distance a normal eye can read that line (for example, 20/40 = at 20 ft, patient reads what a normal person reads at 40 ft). Visual fields by confrontation (monocular static finger-wiggle test) screens for anterior/posterior visual pathway lesions. Color vision is screened with pseudoisochromatic plates.

6.3 External & Pupillary Exam

Inspect palpebral fissures, eyebrows, eyelashes, eyelids, lacrimal apparatus, conjunctiva/sclera, cornea (oblique lighting), iris, and pupils (size/shape/symmetry in dim light; small <3mm, large >5mm).

ReactionDefinition
DirectConstriction in the illuminated eye
ConsensualConstriction in the opposite eye
Near reactionConstriction with convergence; performed if light reaction is impaired

Corneal light reflection assesses ocular alignment (reflection should be slightly medial of pupil center). Extraocular movements are tested in an "H" pattern through the 6 cardinal gaze positions, pausing at extremes to check for nystagmus.

6.4 Ophthalmoscopic Exam

Darken the room, use the same-side hand/eye as the patient's eye being examined, check the red reflex from ~15 inches away before moving in. Adjust diopters (minus/red for myopia, plus/green for hyperopia) to focus. Inspect the optic disc (margins, color, physiologic cup size) and retina (arteries lighter/smaller, veins darker/larger, AV (atrioventricular) crossings, macula/fovea).

7 · General Survey & Vital Signs

Instructional Objectives

  1. Discuss the proper clinical skills for a comprehensive examination of the following: general survey; vital signs; pain assessment.
  2. Demonstrate the proper clinical skills for a comprehensive examination of the following: general survey; vital signs; pain assessment.

7.1 Introduction & Pain Assessment

Confirm identity with 2 identifiers: name and date of birth. Pain history uses OPQRST (onset, palliative/provocative, quality, radiation, severity, timing). Acute pain: typically <3–6 months. Chronic pain: typically >3–6 months or recurrent. Nociceptive pain = tissue damage; neuropathic pain = nervous system damage/disease. On a 1–10 scale, always ask the patient what their personal "10" is.

7.2 General Survey

The general survey is the initial overall impression on entering the room: apparent state of health, discomfort/distress, skin color, dress, grooming, affect, posture/gait, and body habitus.

7.3 Temperature & Pulse

Vital signNormal / technique
TemperatureVaries by site (oral, rectal, tympanic, temporal); diurnal variation exists
Heart rateNormal adult: 60–100 bpm; auscultate carotid before palpating

Palpate pulses in 8+ locations (radial, brachial, carotid, femoral, popliteal, posterior tibial, dorsalis pedis). Never palpate both carotids simultaneously — risk of decreased cerebral blood flow and syncope.

7.4 Respirations & Blood Pressure

Normal adult respiratory rate: 12–20/min. Count discreetly (for example, while appearing to palpate the pulse).

BP (blood pressure) technique pearls: cuff positioned ~2.5cm above the antecubital crease; palpatory systolic estimate (inflate until radial pulse disappears, add ~30 mmHg as your starting point) helps avoid missing an auscultatory gap; deflate at 2–3 mmHg/sec. Orthostatic vitals: measure BP (blood pressure)/HR (heart rate) supine, then again after standing.

8 · Cardiovascular & Peripheral Vascular Examination

Instructional Objectives

  1. Review the anatomy of the heart and great vessels.
  2. Discuss the relationship between cardiac anatomy and superficial anatomy of the thorax.
  3. Discuss the relationship between jugular venous pressure and volume status.
  4. Discuss appropriate utilization of the diaphragm and bell of the stethoscope.
  5. Discuss the relationship between the events in the cardiac cycle and physical examination findings including: first and second heart sounds (S1, S2); physiologic splitting of S2 (A2, P2); rate, rhythm, and characteristics/quality of heart sounds and pulses.
  6. Discuss the proper clinical skills for a comprehensive examination of the following: heart; peripheral vasculature.
  7. Demonstrate the proper clinical skills for a comprehensive examination of the following: heart; peripheral vasculature.

8.1 Cardiac Anatomy & Conduction

The SA (sinoatrial) node is the natural pacemaker (60–100 bpm); the AV (atrioventricular) node delays the impulse before the bundle of His/Purkinje fibers. Cardiac output = heart rate × stroke volume; stroke volume depends on preload, contractility, and afterload. Normal ejection fraction ≈ 60%.

8.2 Cardiac Cycle & Auscultation Areas

SoundOriginBest heard
S1Mitral/tricuspid (AV (atrioventricular)) valve closureApex (mitral) & LLSB (tricuspid)
S2Aortic/pulmonic (semilunar) valve closureR 2nd ICS (aortic) & L 2nd–3rd ICS (pulmonic)

Pulse pressure = systolic − diastolic; normal 30–40 mmHg.

8.3 Cardiac Exam Technique

Always auscultate for carotid bruits before palpating the carotids — palpating an artery with an undetected bruit risks dislodging plaque and causing a stroke. Never palpate both carotids simultaneously.

Palpate the precordium for heaves (palms/fingers flat) and thrills (ball of hand, firm pressure) at the aortic/pulmonic/Erb's point/tricuspid/mitral areas. Normal PMI (point of maximal impulse)/apical impulse: 5th ICS (intercostal space), left MCL (midclavicular line), ~2.5cm, brisk gentle tap.

8.4 Peripheral Vascular Anatomy & Exam

Arterial layers: intima (atherosclerosis site), media (smooth muscle/elastin), adventitia. Arterioles are resistance vessels controlling systemic vascular resistance. Veins hold up to 2/3 of circulating blood volume.

Abnormal pulseMeaning
Pulsus parvusWeak pulse — atherosclerotic PVD (peripheral vascular disease)
Pulsus tardusSluggish pulse — aortic stenosis or low cardiac output

Normal capillary refill ≤2–3 seconds. Epitrochlear nodes are usually not palpable when healthy.

9 · HENT (Head, Ears, Nose, Throat) Examination

Instructional Objectives

  1. Review the anatomy of the head, ears, nose, and throat/neck.
  2. Discuss the proper clinical skills for a comprehensive examination of the following: head, face, and scalp; ears; nose and sinuses; oral cavity; oropharynx; neck.
  3. Demonstrate the proper clinical skills for a comprehensive examination of the following: head, face, and scalp; ears; nose and sinuses; oral cavity; oropharynx; neck.
Unlike the abdomen, the HENT (head, ears, nose, throat) region (like most body regions) uses the standard order: Inspection → Palpation → Percussion → Auscultation (IPalPerA).

Objective 1 — Anatomy of the head, ears, nose & throat/neck

Review the relevant anatomy: the head (skull, scalp, face, temporomandibular joint, salivary glands); the ears (auricle, external canal, tympanic membrane, and the middle-ear ossicles); the nose and paranasal sinuses (frontal, maxillary, ethmoid, sphenoid) with the nasal septum and turbinates; the oral cavity and oropharynx (teeth, gums, tongue, palate, tonsils); and the neck (cervical lymph-node chains, thyroid gland, trachea, and the carotid/jugular vessels).

9.1 Head, Face & Ear Exam

Head/scalp/hair/face inspection covers size/shape/contour, lesions/dandruff, color/distribution/texture, and asymmetry/expression/edema. Ear TM (tympanic membrane) landmarks: pars flaccida (small, loose, above the malleus), pars tensa, umbo, cone of light. Otoscope technique: pull the auricle up, back, and slightly away from the head to straighten the canal; brace your hand against the patient's head; insert gently, angled down and forward.

9.2 Auditory Testing

TestTechniqueNormal
Whispered voice2 ft behind patient, occlude/rub tragus of untested ear3/6 correct
WeberTuning fork on vertexHeard midline
RinneMastoid (bone) then near canal (air)Air > bone

Weber lateralizes to the affected ear in conductive loss, and to the unaffected ear in sensorineural loss. Rinne shows bone ≥ air conduction in conductive loss.

9.3 Nose & Oral Cavity Exam

Nasal exam: inspect deformities/asymmetry/polyps/turbinates/mucosa/septum; palpate frontal/maxillary sinuses (press up, avoiding the eyes); transilluminate in a darkened room (decreased glow = fluid-filled sinus). Oral cavity: identify Stensen's duct (parotid, buccal mucosa) and Wharton's duct (submandibular, floor of mouth). Have the patient say "ah" to check symmetrical soft palate/uvula rise.

9.4 Neck & Thyroid Exam

Inspect for symmetry, masses, gland enlargement, visible nodes, and tracheal midline position. Palpate the trachea (index fingers on each side, compare distance to SCM (sternocleidomastoid) bilaterally) and thyroid (anterior, facing the patient; or posterior, displacing the trachea toward the palpating side while the patient swallows). A normal thyroid is often not palpable.

10 cervical lymph node groups: occipital, pre-auricular, posterior auricular, tonsillar, submandibular, submental, superficial cervical, posterior cervical, deep cervical, supraclavicular. Roll a palpable node up-down/side-to-side to differentiate it from muscle or artery.
