Question 1

Ordered: 200 mL of lactated Ringer's solution is being delivered at 33 mL per hr.
How long will the IV take to infuse?

Accepted Answer

$ 6 \mathrm{hr} $ and $ 4 \mathrm{~min} $
 $ 200 \mathrm{~mL}: x \mathrm{hr}=33 \mathrm{~mL}: 1 \mathrm{hr} $ 
$ 33 x=200 $ 
$ x=6.06=6 \mathrm{hr}, 4 \mathrm{~min} $

Proof. $ 6.06 \times 33=200 $
$  \quad $$  \quad $$ 1 \times 200=200 $

Question 2

Calculate the infusion time for an IV of 750 mL of D5W at 60 mL per hr.
How many hr will it take to infuse?

Accepted Answer

$ 12.5 \mathrm{hr} $

$ 60 \mathrm{~mL}: 1 \mathrm{hr}=750 \mathrm{~mL}: x \mathrm{hr} $ 
$ 60 x=750 $
$ x=12.5 \mathrm{hr} $ to infuse $ 750 \mathrm{~mL} $

Proof: $ 1 \times 750=750 $
$  \quad $$  \quad $$ 60 \times 12.5=750 $

Question 3

Ordered: 500 mL to be infused in 90 min. The drop factor on the gravity tubing is 20 gtt/mL.
a. How many drops per min will you set the gravity device?
b. How many mL per hr will infuse if an electronic device is used?

Accepted Answer

a.
$ \frac{20 x}{90} \times 500=\frac{10,000}{90}=111 \mathrm{gtt} $ per $ \min $

b.
$ 500 \mathrm{~mL}: 90 \mathrm{~min}=x \mathrm{~mL}: 60 \mathrm{~min} $
$ 90 x=500 \times 60=30,000 $
$ 90 x=30,000 $
$ x=333.33=333 \mathrm{~mL} $ per hr for $ 500 \mathrm{~mL} $ to infuse in $ 90 \mathrm{~min} $ using an electronic device

Proof $ 500 \times 60=30,000 $
$  \quad $$  \quad $$90 \times 333.3=29,997$
