A nurse is preparing to administer furosemide 0.1 mg/kg via IV bolus to a client who weighs 183 lb. Available is furosemide 10 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.8"]

Step 1 is to convert the client’s weight from pounds to kilograms. Given that 1 kg = 2.2 lb, we calculate:

183 lb ÷ 2.2 = 83.18 kg

Rounding to the nearest hundredth, the client’s weight is 83.18 kg.

Step 2 is to calculate the total amount of medication needed. The prescribed dosage is 0.1 mg/kg, so we calculate:

0.1 mg/kg × 83.18 kg = 8.32 mg

Rounding to the nearest hundredth, the total medication required is 8.32 mg.

Step 3 is to determine the volume to administer. The available concentration of furosemide is 10 mg/mL, so we divide:

8.32 mg ÷ 10 mg/mL = 0.832 mL

Rounding to the nearest tenth, the correct amount to administer is 0.8 mL.

Correct Answer is ["56"]

Explanation

Step 1 is to calculate the total volume to be infused in minutes. This is done by multiplying the total volume (2000 mL) by the drop factor (20 gtt/mL), and then dividing by the total time (12 hr × 60 min/hr). So, (2000 mL × 20 gtt/mL) ÷ (12 hr × 60 min/hr) = 55.56 gtt/min, which rounds to 56 gtt/min.

Correct Answer is ["0.04"]

Explanation

Step 1 is to determine the amount of medication in 1 mL. This is calculated by dividing the total available medication (250 mcg) by the total volume (1 mL):

250 mcg ÷ 1 mL = 250 mcg/mL

Step 2 is to determine how many mL are needed to obtain 10 mcg. This is done by dividing the required dose (10 mcg) by the concentration (250 mcg/mL):

10 mcg ÷ 250 mcg/mL = 0.04 mL

Thus, the correct amount to administer is 0.04 mL.
