A nurse is preparing to administer enoxaparin 1 mg/kg subcutaneous to a client who weighs 165 lb. Available is enoxaparin 30 mg/0.3 mL. How many ml should the nurse administer per dose?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.8"]
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 ["14"]
Explanation
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.
Correct Answer is ["286"]
Explanation
To solve this problem, the nurse needs to convert the client's weight from pounds to kilograms, and then use the formula:
mL = (mg/kg x kg) / (mg/mL)
The client's weight in kilograms is:
126 lb / 2.2 lb/kg = 57.27 kg
The concentration of foscarnet in mg/mL is:
6,000 mg / 500 mL = 12 mg/mL
Plugging these values into the formula, we get:
mL = (60 mg/kg x 57.27 kg) / (12 mg/mL)
mL = (3,436.2 mg) / (12 mg/mL)
mL = 286.35 mL
Therefore, the nurse should administer 286 mL of foscarnet.
