Correct Answer is A

Explanation

Dextrose 50%, add 1 mL to 4 mL injectable saline. To obtain 5 mL of 10% dextrose, 0.5 mL of the 50% dextrose should be diluted with 4.5 mL of sterile water or normal saline. Therefore, the nurse should add 1 mL of the 50% dextrose to 4 mL of injectable saline to get a final concentration of 10% dextrose in 5 mL. This will give the client the appropriate dose.

Choice B is incorrect because adding 2 mL of the 50% dextrose to 3 mL of saline would give a final concentration of 20%, which is higher than the prescribed concentration of 10%.

Choice C is incorrect because adding 3 mL of the 50% dextrose to 2 mL of saline would give a final concentration of 30%, which is significantly higher than the prescribed concentration of 10%.

Choice D is incorrect because adding 4 mL of the 50% dextrose to 1 mL of saline would give a final concentration of 40%, which is much higher than the prescribed concentration of 10%.
