Final answer:
To deliver a 25 g dose of lactulose syrup with a concentration of 10 g per 15 mL, the nurse would need to administer 37.5 mL.
Step-by-step explanation:
The question asks how many milliliters of lactulose syrup a nurse should administer to deliver a dose of 25 g, given that the syrup has a concentration of 10 g per 15 mL. To find the volume needed for one dose, we use the following proportion:
10 g / 15 mL = 25 g / X mL
To solve for X, we cross-multiply and divide:
10 g × X mL = 25 g × 15 mL
X × 10 g = 375 g·mL
X = 375 g·mL / 10 g
X = 37.5 mL
Therefore, to administer a dose of 25 g, the nurse needs to give 37.5 mL of the lactulose syrup.
