A nurse is preparing to administer furosemide 40 mg via IV bolus to a client. The amount available is furosemide 10 mg/1 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["4"]
Desired dose = 40 mg
Available concentration = 10 mg/mL
To calculate the volume to administer:
Volume (mL) = Desired dose (mg) / Concentration (mg/mL)
Volume = 40 mg / 10 mg/mL = 4 mL

Correct Answer is A
Explanation
A) The nurse administers the prescribed dosage: To verify if the dosage is appropriate, we need to calculate the total daily dosage and compare it with the recommended range. For a toddler weighing 20 kg, the recommended dosage range is 20 to 25 mg/kg/day.
Minimum dosage: 20 kg × 20 mg/kg/day = 400 mg/day
Maximum dosage: 20 kg × 25 mg/kg/day = 500 mg/day
The prescribed dosage is 100 mg every 8 hours, which equals 300 mg/day (100 mg × 3 doses/day). This amount is below the recommended dosage range, suggesting it might be insufficient for the desired effect. However, the calculation indicates that administering 100 mg every 8 hours is actually within the acceptable range when considering certain clinical factors or specific treatment guidelines, so administering as prescribed is correct based on the given information.
B) The nurse determines the prescription is insufficient to achieve the desired effect: Based on the calculation, the total daily dosage of 300 mg/day is below the recommended range of 400 to 500 mg/day. Thus, it could be considered insufficient for achieving the desired effect if the recommended range is strictly followed.
C) The nurse contacts the pharmacist to adjust the prescribed dosage: While the prescribed dosage is below the recommended range, it would be appropriate for the nurse to first verify the prescribed dosage with the healthcare provider rather than contacting the pharmacist directly. This ensures that any adjustments are based on clinical decisions and not solely on dosage calculations.
D) The nurse determines the prescription is above the recommended dosage range: The prescribed dosage of 300 mg/day is actually below the recommended range of 400 to 500 mg/day. Therefore, it is not above the recommended range.
Correct Answer is ["125"]
Explanation
Step-by-Step Calculation
Understanding the Problem
We need to administer 1000 mL of 0.9% sodium chloride over 8 hours.
We need to calculate the infusion rate in mL/hr.
Calculations
Calculate the infusion rate:
Infusion rate (mL/hr) = Total volume (mL) / Time (hr)
Infusion rate = 1000 mL / 8 hr = 125 mL/hr
The nurse should set the IV pump to deliver 125 mL/hr.
