Calculation
A nurse is preparing to administer furosemide 80 mg via IV bolus to a client. The amount available is furosemide 40 mg/mL. How many mL should the dose? And to the nearest whole number. Enter numeric value only (numbers and decimal points only, no commas or labels)
mL
Explanation & Rationale
Identify the given information: Prescribed dose: 80 mg of furosemide Available concentration: 40 mg/mL Determine the volume to be administered: Set up a proportion to solve for the unknown volume (X): 40 mg/mL = 80 mg/X mL Cross-multiplying gives us: 40 mg x X mL = 80 mg x 1 mL Simplifying: 40X = 80 Solving for X: X = 80 / 40 = 2 mL
