Introduction
In the medical field, physical examination skills are vital for accurately diagnosing and managing patient conditions. This guide aims to provide an overview of essential physical examination skills that are tested in the United States Medical Licensing Examination (USMLE).
I. General Principles
1. Introduction and Preparation
- Introduction: Begin by introducing yourself and obtaining the patient's consent before proceeding with the physical examination.
- Preparation: Ensure a comfortable and private environment for the examination, providing a gown or draping as necessary.
2. Universal Precautions
- Hand hygiene: Always practice proper hand hygiene by washing hands or using sanitizers before and after each patient encounter.
- Personal protective equipment: Utilize gloves, masks, and other protective gear when necessary.
3. Patient Communication
- Establish rapport: Communicate with the patient in a respectful and empathetic manner to build trust and cooperation.
- Explain the process: Inform the patient about the physical examination procedure, including the need to expose specific body parts, to ensure their understanding and cooperation.
- Obtain consent: Obtain informed consent for the examination, explaining its purpose, potential benefits, and any possible discomfort.
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.
- Muscle strength: Evaluate the patient's muscle strength using specific maneuvers.
