A nurse is preparing to administer a loading dose of phenytoin 10 mg/kg by IV bolus to a client who weighs 154 lb. Available is phenytoin50 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies t use a trailing zero.)
The Correct Answer is ["14"]
To answer this question, the nurse needs to perform the following steps:
Convert the client's weight from pounds to kilograms by dividing it by 2.2. 154 lb / 2.2 = 70 kg.
Multiply the client's weight by the loading dose of phenytoin to get the total dose in milligrams. 70 kg x 10 mg/kg = 700 mg.
Divide the total dose by the concentration of phenytoin to get the volume in milliliters. 700 mg / 50 mg/mL = 14 mL.
Round the volume to the nearest whole number. The nurse should administer 14 mL of phenytoin by IV bolus.

Explanation
To calculate the dose of enoxaparin, we need to convert the client's weight from pounds to kilograms.
1 kg=2.2 Ib
? kg= 165Ib
=165/2.2
=75kg
Desired med is 1mg/kg
total dose to administer= 75mg
Available formulation is 30mg/0.3ml
total volume to administer
30mg=0.3ml
75mg= 75*0.3/30
=0.75ml
Rounded off to the nearest tenth = 0.8ml
Correct Answer is ["100"]
Explanation
To calculate the IV pump rate in mL/hr, you need to divide the volume of the solution in mL by the infusion time in hr. In this case, the formula is 100 mL / 1 hr = 100 mL/hr.
Therefore, the nurse should set the IV pump to deliver 100 mL/hr of metronidazole.
