Question

A heparin drip (IV) has been ordered that contains 10,000 units of heparin in 1000ml of D5W (5% dextrose in water). The drip is set to run at 50 ml/hr. How many units of heparin does the patient receive in 24 hrs? (Dimensional analysis)

Answer 1

Answer:

12,000 units of heparin are received by patient in 24 hours.

Explanation:

10,000 units of heparin in 1000ml of D5W.

Units of heparin in 1 mL = $\frac{10,000}{1000}=10 units$

Rate at heparin drip set at = 50 ml/hour

Units of heparin in 50 ml of solution = $50\teimes 10 units =500 units$

500 units of heparin are received by patient in an every hour.So, in 24 hours patient will receive:

$500units\times 24 = 12,000 units$ of heparin

12,000 units of heparin are received by patient in 24 hours.
