Health assessment is an organized and systematic approach using the techniques of inspection, palpation, percussion, and auscultation to obtain baseline data on the patient, to supplement or question data obtained in the nursing history, and to obtain data that will help the nurse establish nursing diagnosis and plan of care.
Observe the person's race, sex, general physical development, nutritional state, mental alertness, affect, evidence of pain, restlessness, body position, clothes, and apparent age.
Careful observation of the general state of the individual provides many clues about a person's body image, how they behave, and some idea of how well or ill they are.
During the examination of the abdomen, it is important to flex the patient’s knees to relax the abdominal muscles, which facilitates examination of the abdominal organs.
If ophthalmoscopy is done, the room should be darkened for better illumination, and this should be explained to the client to prevent unnecessary anxiety.
The sense of touch is used to assess the factors: texture, temperature, moisture, organ location and size, any swelling, vibration, or pulsation, rigidity or spasticity, crepitation, presence of lumps or masses, and presence of tenderness or pain.
The technique requires occasional use of certain instruments such as ophthalmoscope (for eye inspection), otoscope (ear inspection), penlight, nasal and vaginal speculum to facilitate viewing.
The technique can be done using different parts of the hands as follows: fingertips for fine tactile discrimination, a grasping action of the fingers and thumb to detect the position, shape and consistency of an organ or mass, and the back of the hands and fingers for temperature.
Light palpation involves placing your dominant hand lightly on the surface of the structure and using a circular motion to feel for easily palpable body organs and masses.
Moderate palpation involves depressing the skin surface 1 - 2 cm (0.5 - 0.75 inch) with your dominant hand, and using a circular motion to feel for easily palpable body organs and masses.
Deep palpation involves placing your dominant hand on the skin surface and your non dominant hand to apply pressure, resulting in surface depression between 2.5 and 5 cm (1 and 2 inches), allowing you to feel very deep organs or structures that are covered by thick muscle.
A female nurse assesses a female client and if a female client will be examined by a male nurse, a female nurse must be in attendance to ensure that the procedure is done in an ethical manner.
