A nurse is preparing to titrate morphine 5 mg via tv bolus to a client. The amount available 6 morphine 8 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.63"]
Determine the desired dose.
The nurse needs to administer 5 mg of morphine.
Calculate the available dose per mL.
The available morphine is 8 mg/mL.
Calculate the volume to be administered.
Volume = Desired dose (mg) / Concentration (mg/mL) = 5 mg / 8 mg/mL = 0.625 mL
Round the volume to the nearest hundredth.
Volume = 0.63 mL

Correct Answer is ["8"]
Explanation
Rationale:
Determine the total volume to be infused.
The nurse is preparing to administer 150 mL of dextrose 5% in water (DW).
Calculate the infusion rate in mL/min.
The infusion time is 3 hours, which is equivalent to 3 x 60 = 180 minutes.
Infusion rate = Total volume / Infusion time = 150 mL / 180 min = 0.83 mL/min
Apply the drop factor to find the drip rate in gtt/min.
Drop factor of the tubing is 10 gtt/mL.
Drip rate = Infusion rate (mL/min) x Drop factor (gtt/mL) = 0.83 mL/min x 10 gtt/mL = 8.3 gtt/min
Round the drip rate to the nearest whole number.
Drip rate = 8 gtt/min
Correct Answer is ["48"]
Explanation
The patient has a new prescription for:
16 units of regular insulin daily
32 units of NPH insulin subcutaneously at breakfast
To calculate the total number of units the nurse should prepare in the insulin syringe, we need to add the units of each type of insulin:
Total units = Regular insulin units + NPH insulin units Total units = 16 units + 32 units Total units = 48 units
