7.5 mL per dose
10 mL per dose
15 mL per dose
12.5 mL per dose
When setting up the proportion to solve for mL, which correctly matches dose and concentration with consistent units?
0.375 mg over x mL equals 187 g over 5 mL
375 mg over x mL equals 5 mL over 187 mg
375 mg over x mL equals 187 mg over 5 mL
375 g over x mL equals 187 mg over 5 mL
After setting the proportion 375 mg/x mL = 187 mg/5 mL, what is the correct next step to isolate x?
Divide both sides by 375 mg
Add 375 mg to both sides
