the nurse should give 250 mg each $1\frac{1}{3}\ hours$ or each $1\ hour\ 20\ minutes$

step-by-step explanation:

we know that

the nurse has an order to give 750 mg every 4 hours

using proportion

find the time required to give 250 mg

$\frac{4}{750}\frac{hours}{mg} =\frac{x}{250}\frac{hours}{mg} x=4*250/750x=1.33\ hours$

convert to mixed number

$1.33\ hours=1\frac{1}{3}\ hours$

$1\ hour\ 20\ minutes$

therefore

the nurse should give 250 mg each $1\frac{1}{3}\ hours$ or each $1\ hour\ 20\ minutes$
