A client receives a prescription for ciprofloxacin 400 mg intravenously
(IV) every 12 hours to be infused over an hour. The IV bag contains
ciprofloxacin 400 mg in dextrose 5% in water (DW) 200 milk The
nurse should program the infusion pump to deliver how many mL/hr?

calculations:
desired dose: 1.2 million units
available dose: 600,000 units/2 ml
to find the volume to administer, we can use the following formula:
volume to administer = (desired dose / available dose) * volume per dose
volume to administer = (1,200,000 units / 600,000 units/ml) * 2 ml = 4 ml
therefore, the nurse should administer 4 ml of the penicillin solution.
, 37.5
determine the concentration of magnesium sulfate in the iv bag:
the iv bag contains 4 grams (4000 mg) of magnesium sulfate in 500 ml.
concentration = 4000 mg / 500 ml = 8 mg/ml
determine the prescribed infusion rate:
the prescription is for 300 mg/hour.
calculate the infusion rate in ml/hour:
infusion rate (ml/hour) = prescribed dose (mg/hour) / concentration (mg/ml)
infusion rate (ml/hour) = 300 mg/hour / 8 mg/ml
infusion rate (ml/hour) = 37.5 ml/hour

to find out how many ml the nurse should
administer: we can set up a proportion to solve for
the unknown. given:
the prescription is for 1,000,000 units of penicillin g.
the available medication is 1,200,000 units/2 ml.
we can set up the proportion as follows:
1,000,000 units/ x ml = 1,200,000 units/2 ml
solving for x gives us the volume in ml that the nurse should
administer. cross-multiplying and solving for x:
x = 1,000,000 units×2 ml/1,200,000 units
after performing the calculation, we find that x equals 1.67 ml.
so, the nurse should administer 1.7 ml (rounded to the nearest tenth) of the
medication.
