Assume that hospital policy permits recalculation of rates when rates are off schedule and clients are stable. 100 units of regular Humulin insulin in 250 mL 0.9% NS were to infuse at 4 mL/hr. How many units per hour will be delivered?. Select the correct response: O 1.1 O 16 O 1.6 Continue >

Answer 1

1. Ordered dose of humulin insulin is 100units in 250ml of NS at flow rate of 4ml /hr

Using unitary method :-

250 ml of solution has 100units of insulin

1ml of solution will have 100/250units

Then 4ml of solution will have 100/250× 4 = 8/5= 1.6units

The correct option is D)

2. 1. Ordered dose of humulin insulin is 40units in 100ml of NS at flow rate of 10ml /hr

Using unitary method :-

100ml of solution has 40units of insulin

1ml of solution will have 40/100units

Then 10ml of solution will have 40/100× 10 = 4 units

3. Ordered dose of zosyn is 2gm in 100ml D5W over 40min.

Flow rate = Total volume(ml) /Total time (hrs)

= 100ml / 0.66hr

= 166.6 ml/hr

4. Ordered dose of heparin is 800units /hr

Available heparin is 40000units in 1000ml D5W

Using unitary method :

40000units of heparin is available in 1000ml

1unit of heparin will be available in 1000/40000ml

Then 800units will be available in 1000/40000× 800

= 20ml /hr is the answer
