50. An IV of D5W $$500\mathrm{mL}$$ was ordered to infuse over $$10\mathrm{hr}$$ at a rate of $$13\mathrm{gt}/\min$$ (13 $$\mathrm{macrogt}/\min )$$. Drop factor: $$15\mathrm{gtt}/\mathrm{mL}$$ After $$3\mathrm{hr}$$, you notice that $$300\mathrm{mL}$$ of IV solution is left. Recalculate the rate in $$gt/2/\min$$ for the remaining solution. 51. An IV of D5W $$1,000\mathrm{mL}$$ was ordered to infuse over $$8\mathrm{hr}$$ at a rate of $$42\mathrm{gtt}/\min (42\mathrm{macrogt}/\min )$$. Drop factor: $$20\mathrm{gtt}/\mathrm{mL}$$ After $$4\mathrm{hr}$$, you notice that only $$400\mathrm{mL}$$ has infused. Recalculate the rate in $$\mathrm{gt}/\min$$ for the remaining solution. 52. An IV of $$1,000\mathrm{mL}$$ D5 $$1/2$$ NS has been ordered to infuse at $$125\mathrm{mL}/\mathrm{hr}$$. Drop factor: 15 gtt $$/\mathrm{mL}$$ The IV was hung at $$7\mathrm{AM}$$. At $$11\mathrm{AM}$$, you check the IV, and there is $$400\mathrm{mL}$$ left. Recalculate the rate in $$\mathrm{gtt}/\min$$ for the remaining solution.
