A client is to receive 150 mL of IV fluid over a 1 hour period. Drop factor on the IV tubing is 12 gtt/mL Calculate the rate which the nurse should regulate the IV (gtt/min).
The Correct Answer is ["30"]
Convert the total volume to milliliters (mL):
The volume is already given in mL: 150 mL
Convert the time to minutes:
1 hour = 60 minutes
Use the drop factor to find the drops per mL:
The drop factor is given as 12 gtt/mL.
Calculate the total drops:
Total drops = Volume (mL) x Drop factor (gtt/mL)
Total drops = 150 mL x 12 gtt/mL = 1800 gtt
Calculate the flow rate in drops per minute (gtt/min):
Flow rate (gtt/min) = Total drops / Time (minutes)
Flow rate (gtt/min) = 1800 gtt / 60 minutes = 30 gtt/min

Correct Answer is ["25"]
Explanation
Convert the client's weight from pounds to kilograms:
1 lb = 0.454 kg
Weight in kg = 220 lbs x 0.454 kg/lb = 99.88 kg (approximately 100 kg)
Calculate the total daily dose of Methylprednisolone:
Daily dose = 1.5 mg/kg x 100 kg = 150 mg
Calculate the dose per administration:
The daily dose is divided into four equal doses.
Dose per administration = 150 mg / 4 = 37.5 mg
Determine the concentration of the Methylprednisolone:
The medication is supplied as 7.5 mg per 5 mL.
Concentration = 7.5 mg / 5 mL = 1.5 mg/mL
Calculate the volume (in mL) to administer per dose:
Use the concentration as a conversion factor:
Volume (mL) = Dose per administration (mg) / Concentration (mg/mL) Volume (mL) = 37.5 mg / 1.5 mg/mL = 25 mL
Correct Answer is ["15"]
Explanation
Identify the total volume and the flow rate:
Total volume: 750 mL of NSS
Flow rate: 50 mL/hr
Use the formula:
Time (in hours) = Total Volume / Flow Rate
Plug in the values and calculate:
Time = 750 mL / 50 mL/hr
Time = 15 hours
