When the skin is exposed to ultraviolet rays, the skin produces a molecule that is turned into Vitamin D.
Sun is the source of ultraviolet rays important for Vitamin D production. Due to this reason, in the case of Vitamin D deficiency, it is recommended by doctor's to absorb sunlight by skin. The Vitamin D production occurs specifically by UV B rays rays which lie in the range of 290-315 nanometer.
The chemical 7-dehydrocholesterol absorbs these rays and convert to previtamin D3. Further, previtamin D3 isomerizes to Vitamin D. Other than sunlight, Vitamin D can be taken through diet. The sources include seafood like fish, fish oil, dairy products, beef liver etc. Vitamin D is required for bone and teeth formation, muscle contraction, immune system etc.

The answer that sounds most correct would be: B) Open back and sufficient tread.
The nurse would infer anorexia nervosa or bulimia nervosa from finding that a client has six binge-eating episodes every week.
Anorexia nervosa is a condition of starvation in a patient with binge-eating disorder (BED). The patient performs this to lose weight and control excessive food intake. This may badly affect the health of such a patient instead of losing weight. He may also end up gaining an unhealthy weight over it.
Bulimia nervosa is a condition in which the person first overeats and then indulges in self-induced vomiting in order not to gain more calories. The person may not be able to control his eating habits and thus end up eating excessive amounts of food. The person then tries to get out his calories in an unhealthy manner which may affect him abruptly.
Nursing intervention for the two may, thus, include the following:
● Supervising the client with specified meals over time
● Preferring liquids over solid food
● Preferring nutritional food in fixed amounts
● Expecting weight gain of about 0.5kg a week
● Allowing patient to control over food choices
● Sitting with the client while supervising a meal to make him follow the above
