Write down the process of the mid-arm circumference. measurement of height. body mass index. tongue examination. examination the nail beds.

Mid-Arm circumference:
Biceps is the muscle of mid arm. Place the beginning of the tapes in the middle of the biceps (midway between shoulder and elbow joint) take the reading and record it. When you do this in a group, record the circumference of all the students of the group and observe the variation

Measurement of height:

Body Mass Index:
BMI can be calculated by adopting the following formula.
Divide your weight by square of your height.
BMI = Weight / Height X Height
If you measured your weight in kg then measure height in meters.
Normal BMI Range = 18 to 25.
Overweight = more than 25 and less then 29.
Obese = more than 30.

 
Tongue Examination:
Nutritional deficiencies, infections, dysfunction of nerves or even cancer can be detected by examining the tongue. Some key characteristic features of a tongue in normal condition can be noted by physical examination. These are —

1. Colour: Pink red on both upper and lower surface. On lower surface blood vessels may be seen.
2. Texture: Rough on upper surface due to presence of papillae or taste buds. Hair, farrows or ulceration indicates dysfunction.
3. Size: If not swollen, tongue will fit comfortably inside the mouth. The tongue can be examined by the following steps
   1) Make tip of tongue touch roof of mouth to inspect ventral surface.
   2) When protruded out, colour and texture can be noted for any deviation.
   3) Use gauze to hold protruded tongue (wearing gloves) between tongue and index figure and fill the fender areas.

Examination the nail beds:
Nail bed also needs direct physical examination. Nail plate surface discolouration, abnormal cuticle, nail fold or nail shape require inspection. Loss of nails and lesions around nails, need medical attention.
