Question

im struggling with IVPB problems can someone show me how to do this one

er ml. The stock supply of Ceptaz 22. The doctor orders 1000 mL of DSW , 8h. The drop factor is 20 gtts per doctor also orders Ceptaz 20 mg per kg to be added to 100 mL DW over 45 minutes q 6h. The drop factor is 60 gtts per mL. The stock supply of kg to be added to 100 mL DSW IVPB to infuse 1 G is reconstituted with 4.8 mL of sterile water to vield 200 mg per ml. The pati weighs 132 lbs. What is the flow rate of the IVPB in gtts/min? a. 133.3 gtt/min b. 133.33 gtts/min c. 134 gtt/min d. 133 gtts/min e. 130 gtt/min

Answer 1

Dose of ceptaz = 20 mg per kg

Weight of patient = 132 lbs = 132 * 0.45 = 59.4 kg

So dose = 59.4* 20 = 1188 mg

200 mg per ml.

1188 mg in 1/200 * 1188= 5.94 ml

So total volume to be infused over 45 minutes = 100 ml D5W + 5.94

= 105.94 ml

60 gtt = 1ml

105.94 ml = 105.94 * 60 = 6356.4 gtt

Rate of infusion = 6356.4 / 45 = 141.25 gtt/min

But looking at the options ,it can be said that the dose of ceptaz has not been taken into account.

100ml = 100 * 60 = 6000 gtt

So rate of infusion = 6000/45 = 133.33 gtt/min

So answer is B.
