Question

Write out solution if possible, I need full steps to solving the problems , thanks !

Ordered: Lasix 17,000,000 mcg IV push. Available Lasix 7,000 mg in 6 ml. How much Lasix will you administer?

Calculate the iV flow rate of 500 ml of 0.9% NaCl over 4.5 hours. The infusion set has a drop factor of 20 gtt/mL. What is the flow rate in gtt/min.

Answer 1

#. Ordered dose of Lasix is 17000000 mcg IV push.

Available Lasix is 7000mg in 6ml

Convert 17000000mcg to mg

17000000mcg = 17000mg

Using unitary method :-

7000mg of Lasix is available in 6ml

1mg of Lasix is available in 6ml/7000mg

Then 17000mg of Lasix is available in 6ml/7000mg × 17000mg

= 14.5 ml of Lasix will be administered .

#. Total volume of 0.9% of NaCl is 500ml

Total time of infusion - 4.5hr = 270mins

Drop factor of infusion set - 20gtt/ml

Flow rate = Total volume /total time × drop factor

= 500ml / 270mins × 20gtt/ml

= 37.03gtt/min
