leslasic. . .this program won't print out fractions the way you did them. your set up is correct, however.
drugreptonurse. . .i set this up by dimensional analysis. however, i also used the formula dose desired divided by dose on hand to help me do the set up. it becomes a complex fraction of fractions in the numerator and denominator. with dimensional analysis i always write off to the side what labels i want to end up with. in this case, i want to end up with drops per minute, where drops are in the numerator and minutes in the denominator
5mcg / 1kg (dose desired) x 1 / 1 minute (rate desired) x 250ml / 200mg (dose on hand) x 132lbs / 1 (patients weight, given information) x 1mg / 1000mcg (conversion factor) x 1kg / 2.2lb (conversion factor) x 60gtts / 1ml (drip factor of iv tubing to be used) = 9,900,000gtts / 440,000 min (after canceling out all the repeated labels in the numerators and denominators and doing the actual math calculation) = 22.5gtts / 1min (after simplifying) = 23gtts / min (after rounding off).
the problem is still not finished. since microdrip tubing delivers 60gtts per minute, or one drop per second, the rate per minute is the same as the rate per hour. so, you would set the iv pump at 23ml / hour
