Question

The next patient needs a saline solution that is 4 times more diluted than the 0.154 M solution. Using the solution you prepared and distilled water, how would you prepare a 500 mL IV for this patient?

a) Add 100 mL of the 0.154 M solution to 400 mL of distilled water.
b) Add 125 mL of the 0.154 M solution to 375 mL of distilled water.
c) Add 200 mL of the 0.154 M solution to 300 mL of distilled water.
d) Add 300 mL of the 0.154 M solution to 200 mL of distilled water.

Answer 1

To prepare a 500 mL IV solution that is 4 times more diluted than the 0.154 M solution, you would need to add 125 mL of the 0.154 M solution to 375 mL of distilled water.

Step-by-step explanation:

The next patient needs a saline solution that is 4 times more diluted than the 0.154 M solution. To prepare a 500 mL IV solution, you would need to add 125 mL of the 0.154 M solution to 375 mL of distilled water. This ensures that the solution is 4 times more diluted than the original concentration.
