A healthcare provider prescribes furosemide (Lasix) 15 mg IV STAT for a client. How many milliliters should the nurse administer?

• A. 1 mL
• B. 1.5 mL
• C. 1.75 mL
• D. 2 mL

Answer: (B)

To determine the correct volume of furosemide (Lasix) to administer, it's important to know the concentration of the medication available. Typically, furosemide is provided in a concentration of 10 mg/mL. Given this concentration, to administer a dose of 15 mg, the calculation would be:

15 mg ÷ 10 mg/mL = 1.5 mL.

This calculation shows that to achieve the ordered dose of 15 mg, the nurse needs to administer 1.5 mL of the furosemide solution. Thus, the correct choice accurately reflects the amount required for the prescribed medication dosage. This understanding is crucial for ensuring patient safety and effective medication administration.
