As you begin the examination, study the four cardinal techniques of examination. Plan your sequence and  scope of examination and how you will position the patient. The physical examination relies on four classic techniques: inspection, palpation, percussion, and auscultation. 

Inspection 

Close observation of the details of the patient's appearance, behavior, and movement such as facial expression, mood, body habitus and conditioning, skin conditions such as petechiae or ecchymoses, eye movements, pharyngeal color, symmetry of thorax, height of jugular venous pulsations, abdominal contour, lower extremity edema, and gait.

Palpation 

Tactile pressure from the palmar fingers or fingerpads to assess areas of skin elevation, depression, warmth, or tenderness, lymph nodes, pulses, contours and sizes of organs and masses, and crepitus in the joints.

Percussion 

Use of the striking or plexor finger, usually the third, to deliver a rapid tap or blow against the distal pleximeter finger, usually the distal third finger of the left hand laid against the surface of the chest or abdomen, to evoke a sound wave such as resonance or dullness from the underlying tissue or organs. This sound wave also generates a tactile vibration against the pleximeter finger.

Auscultation 

Use of the diaphragm and bell of the stethoscope to detect the characteristics of heart, lung, and bowel sounds, including location, timing, duration, pitch, and intensity. For the heart, this involves sounds from closure of the four valves, extra sounds from blood flow into the atria and ventricles, and murmurs. Auscultation also permits detection of bruits or turbulence over arterial vessels.
