Blood is what kind of solution?
None
Hypertonic
Isotonic
Hypotonic
The Correct Answer is C
Rationale-Blood is considered an isotonic solution because its solute concentration is similar to that of the cells in the body, allowing for free movement of water across cell membranes without causing a net influx or efflux of water. This isotonic nature is crucial for maintaining cell integrity and function.
Isotonic solutions have the same osmotic pressure as body’s plasma
B-Hypertonic solution like 3% saline have higher osmotic pressure compared to plasma. This type of solutions draw water from the cells causing shrinkage
D-Hypotonic solution like 0.45% saline have lower osmotic pressure as compared to plasma. They cause swelling of cells with eventual damage

Correct Answer is C
Explanation
C-Dextrose 5% in 0.9% sodium chloride is the most appropriate fluid for the client as it supplies both caloric, fluid and electrolytes at the same time. This ensures that the client does not go into hypoglycemia and the sodium is lowered
A- Lactated Ringer's and Dextrose 5% in 0.9% sodium chloride are isotonic and hypertonic solutions, respectively, and would not be appropriate choices for treating hypernatremia due to their higher sodium content.
B- The goal is to lower the serum sodium concentration carefully by providing a hypotonic solution. In this case, 0.45% sodium chloride is often recommended as it is a hypotonic fluid and can help to correct the sodium imbalance without overloading the client with sodium. the client requires a fluid with dextrose due to the NPO status and low sodium concentration
D- Dextrose in water (option D) is also hypotonic once the dextrose is metabolized, but it may not be as effective in this scenario as it does not contain electrolytes. The water can tip the client to hyponatremia
