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 A
Explanation
Choice A rationale: The medication can be used for IV administration or IM administration as indicated in the label. Methylprednisolone is a corticosteroid that can be given intravenously to treat inflammatory conditions such as asthma, allergic reactions, rheumatoid arthritis, and multiple sclerosis. The medication label should indicate the route of administration, the concentration, the expiration date, and the storage conditions.
Choice B rationale: According to the label, the medication should not be used for more than 48 hours after reconstitution, and it should be stored in a refrigerator.
Choice C rationale: The vial contains multiple doses, and each dose should be withdrawn with a sterile syringe.
Choice D rationale: The medication should be reconstituted with bacteriostatic water for injection, not with 0.9% sodium chloride.
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
