Question

question: 16 of 25
a nurse is caring for a client is who has a deep vein thrombosis and is prescribed heparin by continuous iv infusion at 1,200 units/hr. available is heparin 25,000 units in 500 ml d5w. 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 concentration of heparin

The concentration \(C=\frac{25000\ units}{500\ mL}=50\ units/mL\)

Step2: Find the volume per hour

We know the rate of heparin is \(1200\ units/hr\). Using the formula \(V=\frac{R}{C}\) (where \(V\) is volume per hour, \(R\) is the rate of heparin in units per hour, and \(C\) is the concentration in units per mL). Substitute \(R = 1200\ units/hr\) and \(C=50\ units/mL\) into the formula: \(V=\frac{1200\ units/hr}{50\ units/mL}=24\ mL/hr\)
