A nurse is preparing to administer fligrastin 250 mcg subcutaneous. How many mg should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.25"]
Calculation:
Determine the ordered dose in micrograms:
Ordered dose: 250 mcg
Convert micrograms to milligrams:
Conversion factor: 1 mg = 1000 mcg
Formula: Dose in mg = Dose in mcg / 1000 mcg/mg
= 250 mcg / 1000 mcg/mg
= 0.25 mg

Correct Answer is ["83"]
Explanation
Calculation:
Determine the total volume to be infused:
Total volume: 250 mL
Determine the total infusion time in minutes:
Infusion time: 30 minutes
Determine the drop factor of the IV tubing:
Drop factor: 10 gtt/mL
Calculate the total number of drops needed:
Formula: Total drops (gtt) = Total volume (mL) × Drop factor (gtt/mL)
= 250 mL × 10 gtt/mL
= 2500 gtt
Calculate the flow rate in drops per minute (gtt/min):
Formula: Flow rate (gtt/min) = Total drops (gtt) / Total time (minutes)
= 2500 gtt / 30 minutes
≈ 83.33 gtt/min
Round the answer to the nearest whole number:
83.33 gtt/min rounded to the nearest whole number is 83 gtt/min.
Correct Answer is ["3"]
Explanation
Calculation:
Calculate the desired dose of nitroglycerin per hour in micrograms:
Ordered dose: 10 mcg/min
Conversion: 10 mcg/min × 60 min/hr = 600 mcg/hr
Determine the concentration of the nitroglycerin solution in micrograms per milliliter:
Total nitroglycerin: 50 mg
Convert milligrams to micrograms: 50 mg × 1000 mcg/mg = 50000 mcg
Total volume of solution: 250 mL
Formula: Concentration (mcg/mL) = Total micrograms / Total mL
= 50000 mcg / 250 mL
= 200 mcg/mL
Calculate the IV pump flow rate in mL/hr:
Formula: Flow rate (mL/hr) = Desired dose per hour (mcg/hr) / Concentration (mcg/mL)
= 600 mcg/hr / 200 mcg/mL
= 3 mL/hr
