Question

You start your shift at 3:00 pm. On nursing assessment rounds, you find that Mr. Johnson has an IV of D5W that is infusing at 32 gtt/min. The IV tubing is calibrated for 15 gtt/mL. How many mL will Mr. Johnson receive during your 8-hr shift?

Answer 1

Mr Johnson will receive 1024 mL IV in 8 hours.

Explanation:

Mr Johnson has an IV that is infusing at 32 gtt per minute.

So in 1 hour patient will get the drug = 32×60 = 1920 gtt

Now in 8 hours drug received by the patient = 1920 × 8

= 15360 gtt

Since IV tube is calibrated for 15 gtt per mL which means in 1 mL amount of drug is 15gtt.

Therefore, total volume of infusion (in mL) will be

=
`\frac{\text{Total drug infused}}{\text{Total drug in 1 mL}}`

=
`(15360)/(15)`

= 1024 mL.

Therefore, 1024 mL IV will be infused in 8 hours.
