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 ["83.3"]
Explanation
Convert the patient's weight to kg.
The patient weighs 185 lb.
1 lb is approximately equal to 0.45 kg.
Patient's weight in kg = 185 lb x 0.45 kg/lb = 83.25 kg
Calculate the dose per administration.
The prescribed dose is 1 mg/kg/dose.
Dose per administration = 1 mg/kg/dose x 83.25 kg = 83.25 mg/dose
Round the dose to the nearest tenth.
Dose per administration = 83.3 mg
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
