Question

question: 10 of 85
a nurse is preparing to administer heparin at 1,000 units/hr via continuous iv infusion to a client who had a coronary artery bypass graft.
available is heparin 25,000 units in dextrose 5% in water in 250 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.)
ml
continue

Explanation:

Step1: Calculate the concentration of heparin

The concentration \(C=\frac{25000\ units}{250\ mL}=100\ units/mL\)

Step2: Calculate the infusion rate

We know the formula \(Rate (mL/hr)=\frac{Dose\ ordered (units/hr)}{Concentration (units/mL)}\)
Substitute the values: \(Rate=\frac{1000\ units/hr}{100\ units/mL}=10\ mL/hr\)

Answer:

\(10\)
