A nurse is preparing to administer foscarnet 60 mg/kg via intermittent IV bolus to a client who weighs 126 lb. Available is foscarnet 6,000 mg in 500 mL of 0.9% sodium chloride solution. How many ml should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["286"]
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.

Correct Answer is ["67"]
Explanation
To solve this problem, the nurse needs to use the formula:
gtt/min = (Volume in mL x Drop factor in gtt/mL) / Time in min
Plugging in the given values, we get:
gtt/min = (100 x 10) / 15
gtt/min = 66.67
Rounding to the nearest whole number, we get:
gtt/min = 67
Therefore, the nurse should set the manual IV infusion to deliver 67gtt/min.

Correct Answer is ["0.8"]
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
