The nurse is explaining the recommended dietary allowances (RDAs) to a client seeking nutritional counseling.
<h3>What are RDAs? </h3>
The Recommended Dietary Allowances (RDAs) for critical nutrients have been assessed by the Food and Nutrition Board to be sufficient to cover the known nutrient needs of practically all healthy individuals.
<h3>
History of RDAs. </h3>
The first Recommended Dietary Allowances (RDAs) were published in 1943, during World War II, with the stated purpose of “establishing criteria to serve as a target for appropriate nutrition.” According to “newer results,” it indicated the “recommended daily intakes for the major nutritional needs for people of different ages” (NRC, 1943).
The history of how the RDAs were developed is explained in-depth by the first chair of the Committee on Recommended Dietary Allowances (Roberts, 1958). Updates have been made to the original article.

Question options:
1. Placing a red blood cell in distilled water
2. Placing a red blood cell into an isotonic solution
3. Placing a red blood cell into a hypotonic solution
4. Placing a red blood cell into a hypertonic solution.
5. Placing a red blood cell with a concentration of 0.9% NaCl into a solution of 1.5% NaCl
6. Placing a red blood cell with an ICF concentration of 0.9% NaCl into a solution with 0.1% NaCl.
Answer:
Crenation (shrinking):
-Placing a red blood cell into a hypertonic solution.
-Placing a red blood cell with a concentration of 0.9% NaCl into a solution. of 1.5% NaCl
Hemolysis (swelling):
-Placing a red blood cell in distilled water.
-Placing a red blood cell into a hypotonic solution.
-Placing a red blood cell with an ICF concentration of 0.9% NaCl into a solution with 0.1% NaCl.
No change:
-Placing a red blood cell into an isotonic solution.
Explanation:
Crenation is an osmotic process in which blood cells shrink while placing <u>hypertonic</u> or alkaline solutions. Hemolysis is the destruction of red blood cells in which cells bloat up and may explode while placing in a<u> hypotonic</u> or acidic solution. The blood cells have no change In an <u>isotonic</u> environment because the relative concentrations of solute and water are equal on both sides of the membrane.
