Question

3. Patients who are unable to take fluids orally are often administered IV fluids of normal saline which is a 0.90% m/v solution of sodium chloride, or 0.15 M NaCl. Based on your observations from this experiment, why is this solution used instead of sterile water?

Answer 1

Hi, Dear student please find solution if you have any query feel free to ask.

Answer:

As we know, a normal saline IV fluid which is 0.90% m/v solution of sodium chloride, it means this solution contains 0.9 g of NaCl in 100 mL of physiological saline. This solution is used for treatment of fluid loss and maintains the sodium chloride balance in the body. The patient who is unable to take fluids and nutrients orally, this solution gives intravenously to the patient to maintain the sodium chloride balance in the body which is very essential for the survival of patient.

Sterile water contains water that is sterilized and used as an irrigant; it contains no bactriostat, antimicrobial agent, this water is used for dissolve the drugs for injection purpose. Sterile water is the type of water which is highly sterile (in normal term purified water or boiled water).

On the bases of my observation saline IV fluid which is 0.90% m/v solution of sodium chloride cannot we use in place of sterile water.
