Physical Examination Techniques

Topic Overview

Physical examination techniques are the foundation of the clinician’s ability to gather objective data. A systematic approach ensures that findings are reliable, reproducible, and interpretable. In the Family Nurse Practitioner (FNP) role, mastery of these techniques is essential for accurate diagnosis, monitoring disease progression, and building patient trust. On exams, you will be tested on the correct sequence, appropriate technique for each body system, and the clinical significance of specific findings.

Key Concepts and Definitions

  • Inspection – Visual observation of the patient. First step in every examination. Requires adequate lighting and full exposure of the area.
  • Palpation – Using touch to assess texture, temperature, moisture, organ size, tenderness, and masses. Performed with the pads of fingers (fine discrimination) or palmar surface (vibration, texture).
  • Percussion – Tapping the body surface to produce sound waves that indicate underlying density. Four notes: tympany (gas, stomach), hyperresonance (emphysema), resonance (normal lung), dullness (solid organs, fluid), flatness (bone, muscle).
  • Auscultation – Listening to sounds produced by the body (heart, lungs, blood vessels, abdomen). Performed with a stethoscope. For heart and lungs, use the diaphragm (high-pitched sounds) and bell (low-pitched sounds).
  • Sequence – For most body systems: inspect, palpate, percuss, auscultate. Exception: abdominal exam follows: inspect, auscultate, percuss, palpate.

Core Principles and Processes

General Approach

  • Always explain each step to the patient before touching. Use a warm, gloved hand when appropriate.
  • Maintain a quiet environment. Minimize background noise for accurate auscultation.
  • Compare symmetric sides. Always examine both left and right to detect asymmetry.
  • Start with inspection, then proceed in a logical order to avoid excessive repositioning.

Step-by-Step: Abdominal Examination

  1. Inspect – Contour, scars, distention, visible pulsations, peristalsis. Patient supine with arms at sides.
  2. Auscultate – Before palpation/percussion (to avoid altering bowel sounds). Use diaphragm, listen in all four quadrants. Normal: 5–35 clicks/gurgles per minute. Absent sounds require listening for 5 minutes.
  3. Percuss – Assess liver span, splenic dullness, tympany over gas, dullness over masses or fluid. Start in the right lower quadrant, move clockwise.
  4. Palpate – Light (1 cm) then deep (4–6 cm). Assess tenderness, guarding, masses, organomegaly. Rebound tenderness suggests peritoneal irritation.

Step-by-Step: Cardiovascular Examination

  1. Inspect – Precordial movements, jugular venous distention, peripheral edema, skin color.
  2. Palpate – Point of maximal impulse (PMI) location, lifts, heaves, thrills. PMI normally at 5th intercostal space, midclavicular line.
  3. Auscultate – Over the four classic valve areas (aortic, pulmonic, tricuspid, mitral). Use diaphragm for S1, S2, murmurs; bell for S3, S4, mitral stenosis rumble. Listen with patient supine, left lateral recumbent, and sitting leaning forward.

Step-by-Step: Respiratory Examination

  1. Inspect – Chest symmetry, retractions, use of accessory muscles, rate, rhythm, depth.
  2. Palpate – Tactile fremitus (increased with consolidation, decreased with effusion or pneumothorax).
  3. Percuss – Resonance over normal lung, dullness over consolidation or effusion, hyperresonance over pneumothorax or COPD.
  4. Auscultate – Use diaphragm. Compare symmetric locations. Note breath sounds (vesicular, bronchovesicular, bronchial, absent) and adventitious sounds (crackles, wheezes, rhonchi, pleural rub).

Signs, Symptoms, and Findings

  • Inspection findings: Cyanosis, pallor, clubbing, jaundice, visible pulsations, scars, asymmetry, spider angiomas, caput medusae.
  • Palpation findings: Tenderness, guarding, rebound tenderness, masses, organomegaly, nodal enlargement, crepitus, thrills, lifts, temperature changes.
  • Percussion findings: Tympany (normal abdomen over gas-filled bowel), dullness (liver, spleen, bladder, solid mass), resonance (normal lung), hyperresonance (emphysema, pneumothorax).
  • Auscultation findings:
    • Heart: S1 (mitral/tricuspid closure), S2 (aortic/pulmonic closure), S3 (ventricular gallop, early diastole – often normal in children, pathological in adults), S4 (atrial gallop, presystolic – usually pathological). Murmurs (systolic/diastolic, location, radiation, grade 1–6).
    • Lungs: Crackles (fine – pulmonary edema, coarse – bronchitis), wheezes (high-pitched – asthma, low-pitched – COPD), rhonchi (sonorous, clearing with cough), pleural friction rub (grating, pleuritis).
    • Abdomen: Bowel sounds (hyperactive – diarrhea, early obstruction; hypoactive – ileus, peritonitis; bruits – vascular stenosis).

Assessment and Interpretation

  • Differentiate normal from abnormal: Know the expected findings for each age group (e.g., infant vs. elderly).
  • Integrate findings: A dull percussion note with decreased breath sounds and increased tactile fremitus suggests consolidation (pneumonia). Dullness with absent breath sounds suggests pleural effusion.
  • Red flags: Barrel chest with hyperresonance (COPD), asymmetric chest expansion with dullness (mass or effusion), absent bowel sounds with rigid abdomen (peritonitis – surgical emergency).
  • Documentation: Use precise terminology. Describe size, location, intensity, quality. Example: “2/6 holosystolic murmur loudest at apex, radiating to axilla.”

Treatment and Interventions (FNP Role)

  • Physical exam findings guide immediate interventions:
    • Abnormal lung sounds with hypoxia → administer oxygen, consider bronchodilators.
    • Cardiac murmur with signs of heart failure → initiate diuretics, order echocardiogram, consult cardiology.
    • Abdominal tenderness with guarding and absent bowel sounds → obtain upright abdominal X-ray, NPO, IV fluids, surgical consultation.
  • Patient education: Explain the reason for the exam steps (e.g., “This deep pressure checks for any tenderness under your rib cage.”).
  • Follow-up: Based on findings, order lab tests, imaging, or further specialist evaluation. Document all findings to trend over time.

Safety Precautions and Complications

  • Always warm your hands and stethoscope to avoid startling the patient.
  • Use standard precautions: Gloves when assessing mucous membranes, wounds, or non-intact skin.
  • Be gentle with palpation especially in patients with suspected abdominal pain, fractures, or fragile skin (elderly, steroids).
  • Avoid excessive pressure on the carotid sinus when palpating carotid pulses (risk of bradycardia or syncope).
  • Do not percuss over an obvious pulsatile mass (suspected AAA) – risk of rupture.
  • Auscultate before palpation/percussion in abdominal exam to avoid altering bowel sounds.
  • Recognize patient distress: If a patient exhibits severe pain during any part of the exam, stop and reassess. Never force palpation.

Exam Tips and High-Yield Points

  • Remember the abdominal sequence: I A P P (Inspect, Auscultate, Percuss, Palpate). Repeat it: “I Am a Patient Practitioner.”
  • Percussion notes mnemonic: “T H R D F” (Tympany, Hyperresonance, Resonance, Dullness, Flatness).
  • Auscultation of the heart: Diaphragm for high-pitched sounds (S1, S2, pericardial rubs, most murmurs). Bell for low-pitched sounds (S3, S4, mitral stenosis rumble).
  • Breath sounds:
    • Vesicular – soft, low-pitched, heard over most lung fields (inspiration longer than expiration).
    • Bronchovesicular – medium pitch, equal inspiration/expiration, heard over mainstem bronchi (manubrium).
    • Bronchial (tubular) – loud, high-pitched, heard over trachea (expiration longer than inspiration).
    • Bronchial sounds heard elsewhere indicate consolidation.
  • High-yield for exams:
    • Pleural effusion: dull percussion, decreased breath sounds, decreased tactile fremitus.
    • Pneumonia: dull percussion, bronchial breath sounds, increased tactile fremitus, egophony (“E to A” change).
    • Pneumothorax: hyperresonance, absent breath sounds, decreased fremitus.
    • Aortic stenosis: systolic ejection murmur at right upper sternal border, radiating to carotids.
    • Mitral regurgitation: holosystolic murmur at apex, radiating to axilla.
    • Acute abdomen: absent bowel sounds, rebound tenderness, guarding, percussion pain → suspect peritonitis.
  • Practice the correct order: Always begin with inspection. Never start with palpation or percussion for the abdomen. This is a common exam trap.
  • Memory aid for abdominal quadrants:
    • RUQ: liver, gallbladder, duodenum, head of pancreas, right kidney.
    • LUQ: stomach, spleen, body of pancreas, left kidney.
    • RLQ: appendix, cecum, right ovary.
    • LLQ: sigmoid colon, left ovary.
