A client who had a small bowel resection two weeks ago is receiving 3/4 strength Ensure feedings 275 ml
every 4 hours via nasogastric tube. Full strength Ensure is available in a 240 ml can. The nurse should use how
many ml of Ensure to prepare the feeding? (Enter numeric value only. Round to nearest whole number if
needed.)
Using the formula Desired % / on Hand % x Volume Desired = 75/100 x 275 = 0.75 x 275 = 206 Ensure
206 ml Ensure + 69 ml water = 275 ml (75% solution)
A client admitted to the unit from the emergency room receives a prescription for an IV infusion of 0.9%
sodium chloride 1,000 ml at 750 ml/4 hours. The IV administration set delivers 60 gtts/ml. The nurse should
regulate the infusion to deliver how many gtts/minute? (Enter numeric value only. If rounding is required,
round to the nearest whole number.)
First convert hours to minutes: 4 hours x 60 = 240 minutesUsing formula Volume/Time x gtt factor: 750 ml/240
min = 3.125 x 60gtts = 187.5 (rounding to) 188 gtts/minute

The nurse is preparing a tube feeding of Ensure 280 ml (50% solution). Full strength Ensure is available in a 240
ml can. The nurse should use how many ml of Ensure to prepare the feeding? (Enter numeric value for only. If
rounding is required, round to nearest whole number.)
Using the formula D/H (Desired % / % on Hand) x Total volume desired:
50/100 x 280ml = 0.5 x 280 ml = 140 ml Ensure + 140 ml water = 280 ml (50% solution)
A client scheduled for a stress echocardiogram is to receive an IV infusion of Dextrose 5% in Water (D5W) with
dobutamine (Dobutrex) 0.5 grams/250 ml at a rate of 1,200 mcg/minute. The nurse should program the infusion
pump to deliver how many ml/hour? (Enter numeric value only. If rounding is required, round to the nearest
whole number.)
First calculate the number of mcg/hour: 1,200 x 60 minutes = 72,000 mcg/hourNext calculate the number of
ml/hour needed to administer 72,000 mcg/hour500,000 mcg : 250 ml :: 72,000 mcg : X500,,000 :: 250 /
