Answer:
Mr Johnson will receive 1024 mL IV in 8 hours.
Step-by-step 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
= [tex]\frac{\text{Total drug infused}}{\text{Total drug in 1 mL}}[/tex]
= [tex]\frac{15360}{15}[/tex]
= 1024 mL.
Therefore, 1024 mL IV will be infused in 8 hours.
