4. Patient Positioning and Comfort

  • Positioning: Guide the patient into appropriate positions to facilitate examination of different body systems, ensuring their comfort and modesty.
  • Drapping: Use drapes or gowns to maintain patient privacy and to expose only the necessary body parts during the examination.

II. Systems-Based Examination

1. Vital Signs

  • Temperature: Measure the patient's body temperature using a thermometer.
  • Blood pressure: Assess the patient's blood pressure using a sphygmomanometer and stethoscope.
  • Pulse: Determine the patient's pulse rate and rhythm using palpation or auscultation.
  • Respiratory rate: Observe and count the patient's respiratory rate.

2. Head and Neck Examination

  • Inspection: Observe the patient's face, scalp, hair, facial symmetry, and skin for abnormalities.
  • Palpation: Examine the patient's scalp, lymph nodes, sinuses, and thyroid gland for abnormalities.
  • Ophthalmoscope: Use an ophthalmoscope to evaluate the patient's visual acuity, fundus, and optic disc.
  • Otoscope: Examine the patient's external ear canal, tympanic membrane, and middle ear using an otoscope.
  • Nose and throat: Assess the patient's nasal cavity, oral cavity, and oropharynx for abnormalities.

3. Cardiovascular Examination

  • Inspection: Observe the patient's jugular venous distention, visible pulsations, and chest deformities.
  • Palpation: Assess the patient's pulses, precordial heave, and apex beat.
  • Auscultation: Use a stethoscope to listen for heart sounds, murmurs, and abnormal sounds.

4. Respiratory Examination

  • Inspection: Observe the patient's respiratory effort, chest wall symmetry, and skin color.
  • Palpation: Assess the patient's chest expansion, tactile fremitus, and vocal fremitus.
  • Percussion: Tap the patient's chest to assess lung resonance and dullness.
  • Auscultation: Listen to the patient's lung sounds using a stethoscope.

5. Abdominal Examination

  • Inspection: Observe the patient's abdominal contour, scars, and any visible masses.
  • Auscultation: Listen for bowel sounds in all quadrants of the patient's abdomen.
  • Percussion: Gently tap the patient's abdomen to assess for organ enlargement, fluid, or masses.
  • Palpation: Carefully palpate the patient's abdomen to evaluate organ size, tenderness, and masses.

6. Neurological Examination

  • Mental status: Assess the patient's level of consciousness, orientation, and cognitive function.
  • Cranial nerves: Evaluate the patient's cranial nerves using specific tests.
  • Motor examination: Assess muscle strength, tone, coordination, and reflexes.
  • Sensory examination: Test the patient's sensation to touch, pain, temperature, and proprioception.

7. Musculoskeletal Examination

  • Inspection: Observe the patient's posture, gait, and joint deformities.
  • Palpation: Assess the patient's joints, bones, and muscles for tenderness, swelling, or masses.
  • Range of motion: Test the patient's active and passive range of motion for each joint.
