.91 saline is normal saline which is isotonic. 5% dextrose is also isotonic. so the combination is still isotonic
Normal Saline Solution in 5% Dextrose or D5NSS is a hypertonic solution. It can be used for the temporary treatment of shock if plasma expanders are not available. However, do not administer this IV for clients with cardiac or renal conditions.
it is 1/5 saline
Common isotonic IV solutions include 0.9% normal saline (NS), lactated Ringer's (LR) solution, and 5% dextrose in water (D5W). These solutions have a similar osmolarity to blood plasma and are often used to restore fluid balance in the body.
The osmolality of 5% dextrose with normal saline will be approximately 560 mOsm/kg. This calculation takes into account the osmolality contributions of both dextrose and normal saline components. It is important to note that osmolality measures the concentration of osmotically active particles in a solution.

5 percent dextrose (D5W) is not considered isotonic; it is classified as hypotonic. While D5W initially has an osmolarity similar to that of blood plasma, the dextrose is quickly metabolized by the body, leaving free water that dilutes the plasma and can lead to a decrease in osmotic pressure. As a result, it is often used in clinical settings to provide hydration rather than to maintain isotonicity.
Normal saline solution (0.9% NaCl) is considered isotonic with blood (although it actually has a slightly higher degree of osmolality). Ringers lactate is also considered isotonic.5% Dextrose solution is also considered hypotonic compared with blood, because although it is isotonic while infusing, the dextrose is metabolized and free water is left, which is hypotonic.
D5NSS stands for Dextrose 5% in Normal Saline Solution. It is a type of intravenous fluid that contains dextrose (sugar) and saline (salt solution). It is used to provide a source of glucose for energy and to help maintain fluid and electrolyte balance in the body.
it means 5% dextrose in 0.45% saline. This is a hypertonic solution and useful to treat hypovolemia and hyponatremia.
1. D5W=Dextrose 5% in water 2. Normal saline=0.9% NaCl 3. 1/2 Normal saline=0.45% NaCl
A hypotonic solution has less than normal tension: hypo = less, and tonic = tonicity, the concentration of solute. Examples of hypotonic solutions: (1) Sports drinks that contain salts / electrolytes (2) physiologically: a. 0.45% NaCl (half-normal saline solution); since normal saline is 0.9% NaCl, any solution less than 9% is hypotonic b. dextrose 2.5% in water c. dextrose 2% in water
it called 5 % Dextrose because contains 5 gram of Dextrose / 100ml of Water (5% Dextrose in Water)
