Answer 1

34.Heparin infusion rate = Total units (in IV bag)= units / hour

Total volume (ml) (X) ml/hr

Available heparin infusion comes in 250ml (total volume ) with 25000 units of heparin (total units)

The ordered heparin is 1400 units over an hour

Applying the formula :-

= 25000 = 1400

250. (X) ml/hr

= 1400× 250 /25000(X)

= 14ml/hr , X =14ml/hr

35 . a) i - The order dose is 500mg in 250 ml of 5%D/W.

Available lidocaine is 200mg/ml

Then to give 500 mg we have to take :-

200mg of lidocaine is present in 1ml of solution

1mg of lidocaine is present in 1/200 ml of solution

500 mg of lidocaine will be present in 1/200 × 500

= 2.5 ml

2.5 ml of lidocaine will be added to 250 ml of 5%D/W.

a) ii - Flow rate = Total volume to be infused/ total time in mins × drop factor

Total volume = 250ml of 5%D/W

Total time = 60min

Drop factor = 25 πgtt/ min

Applying the formula:-

= 250ml /60 mins ×25πgtt/ min

= 327.2 ml/hr

a) iii-. Total time is changed to 5 hrs

Total volume = 250ml

Drop factor = 25πgtt/ min

Apply the formula :-

Total volume / total time × drop factor

= 250 ml / 5× 60 × drop factor

= 250ml / 300min × 25πgtt/ min

= 65.4 ml / hr
