Question

question: 4 of 25
a nurse is preparing to administer a continuous heparin infusion at 1600 units/hr. available is heparin 25,000 units in dextrose 5% in water (d₅w) 500 ml. the nurse should set the iv pump to deliver how many ml/hr? (round the answer to the nearest whole number. use a leading zero if it applies. do not use a trailing zero.)

Explanation:

Step1: Calculate the units per mL

We know that there are 25000 units in 500 mL. So the units per mL is $\frac{25000}{500}=50$ units/mL.

Step2: Calculate the mL per hour

The infusion rate is 1600 units/hr. Let $x$ be the mL/hr. Since units = units/mL×mL, we have $1600 = 50\times x$. Solving for $x$, we get $x=\frac{1600}{50}=32$ mL/hr.

Answer:

32
