Answer:
See below for answer
Explanation:
<u>A. 200 mOsM NaCl</u>
This solution is hypotonic to the red blood cell (RBC) with penetrating solute. The RBCs will swell up and burst because the water will move into the cells.
<u>B. 400 mOsM urea</u>
This solution is hypertonic to the RBCs with non-penetrating solutes. Water will leave the cells via osmosis and the cells will shrink and appear shriveled.
<u>C. 100 mOsM urea plus 200 mOsM NaCl</u>
This time both penetrating and non-penetrating solute is present. The solution is isotonic to the RBCs and although there will be movement of water between the cells and the solution, there will be no overall change in the concentration of water for each and no change in appearance of the cells.
<u>D. 300 mOsM urea</u>
The RBCs will not lyse nor shrivel as again the solution is isotonic to the RBCs.
Answer: c. Restricted in fat to prevent steatorrhea
Explanation:
Cystic fibrosis is a disease which is inherited by the children from their parents genetically. It affects the digestive as well as the respiratory system of the body. It makes the person sick leads to the disrupting functioning of the epithelial cells. The epithelial cells are responsible for making up the sweat glands in the skin, lining of the lungs, digestive and reproductive organs of the body.
The following are the diets which should be taken by the patients of cystic fibrosis.
a. High in calories to prevent malnutrition: A patient may require high calories even in minor infection as the disease is exhausting and can create weakness in the body.
b. Includes liberal salt usage to replace electrolytes: The patients with cystic fibrosis loose lot of salt in sweat, to maintain the electrolytic balance in the body salt content should be maintained in the diet.
d. Includes dietary supplements and shakes: Calcium present in the diary products and shakes will provide strength to the bones.
c. Restricted in fat to prevent steatorrhea is the correct option. As the diet must contain fat content which can be utilized to produce instant energy in the body as the disease is exhausting.
