A client with myasthenia gravis is receiving pyridostigmine 150 mg PO every 4 hours. The medication is available as 60 mg in 5 mL syrup. How many mL should the nurse administer? (If rounding is required, round to the nearest tenth.)
The Correct Answer is ["12.5"]
Desired dose = 150 mg
Available concentration = 60 mg / 5 mL
Calculate the volume to administer:
Volume to administer (mL) = Desired dose (mg) / Concentration (mg/mL)
= 150 mg / (60 mg / 5 mL)
= 150 mg / 12 mg/mL
= 12.5 mL

Correct Answer is ["5.5"]
Explanation
Calculate the total volume to administer:
Total volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 55 mg / (100 mg / 20 mL)
= 55 mg / 5 mg/mL
= 11 mL
Infusion time in minutes = 2 minutes
Calculate the volume to administer per minute:
Volume per minute (mL/minute) = Total volume (mL) / Infusion time (minutes)
= 11 mL / 2 minutes
= 5.5 mL/minute
Correct Answer is ["83"]
Explanation
Formula:
Infusion rate (mL/hour) = Total volume (mL) / Total time (hours)
Convert total volume from liters to milliliters:
1L = 1000mL
2L = 2 liters x 1000 mL/litre
= 2000 mL
Total volume = 2000 mL
Total infusion time in hours:
Total infusion time = 24 hours
Calculate the infusion rate in mL/hour:
Infusion rate (mL/hour) = Total volume (mL) / Total time (hours)
= 2000 mL / 24 hours
≈ 83.33 mL/hour
Round to the nearest whole number:
Rounded infusion rate = 83 mL/hour
