The health-care provider prescribes furosemide (Lasix) 25 mg IV. The drug is available in a solution of 40 mg/4ml. How many ml should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["2.5"]
To calculate the volume of furosemide to be administered, we can use the following formula:
Volume to administer = (Prescribed dose) / (Concentration)
Plugging in the given values:
Volume to administer = 25 mg / (40 mg/4 mL)
Volume to administer = 25 mg x (4 mL / 40 mg)
Volume to administer = 2.5 mL
Therefore, the nurse should administer 2.5 mL of furosemide (Lasix).

Correct Answer is ["5.8"]
Explanation
To calculate the infusion rate, we'll follow these steps:
1. Calculate the desired dose rate in mcg/minute:
Desired Dose Rate = Weight (kg) x Dose (mcg/kg/minute)
Desired Dose Rate = 86 kg x 8 mcg/kg/minute
Desired Dose Rate = 688 mcg/minute
2. Convert micro-grams to milligrams:
688 mcg x (1 mg / 1000 mcg) = 0.688 mg/minute
3. Calculate the concentration of dopamine in the IV solution:
Dopamine Concentration = Dopamine (mg) / Solution Volume (mL)
Dopamine Concentration = 800 mg / 500 mL
Dopamine Concentration = 1.6 mg/mL
4. Set up a proportion:
x mL/hour / 0.688 mg/minute = 60 minutes/hour / 1.6 mg/mL
5. Cross-multiply and solve for x:
x mL/hour = 0.688 mg/minute x 60 minutes/hour / 1.6 mg/mL
x mL/hour ≈ 25.8 mL/hour
Therefore, the nurse should program the infusion pump to deliver approximately 25.8 mL/hour.
Correct Answer is ["499"]
Explanation
Calculating the Lactated Ringer's Infusion Rate
Step 1: Convert pounds to kilograms:
110 pounds x (1 kg / 2.20462 pounds) ≈ 49.9 kg
Step 2: Calculate the total fluid requirement for 24 hours using the Parkland formula:
Total Fluid (mL) = 4 mL/kg/%TBSA x Body Weight (kg) x %TBSA
Total Fluid = 4 mL/kg/%TBSA x 49.9 kg x 40%
Total Fluid = 7984 mL
Step 3: Calculate the fluid volume for the first 8 hours:
First 8 Hours Fluid = Total Fluid / 2
First 8 Hours Fluid = 7984 mL / 2
First 8 Hours Fluid = 3992 mL
Step 4: Calculate the infusion rate for the first 8 hours:
Infusion Rate (mL/hour) = First 8 Hours Fluid / 8 hours
Infusion Rate = 3992 mL / 8 hours
Infusion Rate ≈ 499 mL/hour
Therefore, the nurse should set the infusion pump to deliver approximately 499 mL/hour during the first 8 hours.
