A client retums from the post anesthesia care unit (PACU) with a bag of intravenous (IV) fluids that has 630 mL remaining in the 1,000 mL bag. The prescription reads, "Continue the present IV over the next 7 hours." The IV administration set delivers 10 gtt/mL. The nurse should regulate the infusion to deliver how many drops/minute to accomplish the new prescription? (Enter numeric value only).

Answer and Explanation

The Correct Answer is ["15"]

Here's what we know:

Volume remaining in the bag: 630 mL

Total volume to be infused (remaining volume): 630 mL (since we're using the remaining volume)

Infusion time: 7 hours

Drop factor (delivery rate per mL): 10 gtt/mL

We need to find:

Infusion rate (gtt/min)

Steps to solve:

Convert hours to minutes:

Infusion time (hours) = 7

Conversion factor: 1 hour = 60 minutes

Infusion time (minutes) = 7 hours x 60 minutes/hour = 420 minutes

Calculate the required infusion rate (gtt/min):

Total volume to be infused (mL) = 630 mL

Drop factor (gtt/mL) = 10 gtt/mL

Infusion time (minutes) = 420 minutes

Infusion rate (gtt/min) = (Total volume (mL) / Infusion time (minutes)) x Drop factor (gtt/mL)

Infusion rate (gtt/min) = (630 mL / 420 minutes) x 10 gtt/mL

Infusion rate (gtt/min) = 15 gtt/min (rounded to the nearest whole number)

Therefore, the nurse should regulate the infusion to deliver approximately 15 drops/minute.

Correct Answer is ["10"]

Explanation

First, we need to calculate the total amount of medication that will be administered in a day.

The prescription is for 250 mg every 8 hours, which means three doses per day (since there are 24 hours in a day).

Therefore, the total daily dosage is 250 mg x 3 = 750 mg.

Next, we need to find out how many milligrams are in the entire bottle.

Since each 5 mL contains 250 mg, we can calculate this by setting up a proportion:

(250 mg / 5 mL) = (Total mg / 150 mL)

Solving for Total mg gives us:

Total mg = (250 mg / 5 mL) * 150 mL Total mg = (50 * 150) Total mg = 7500 mg

Now that we know there are a total of 7500 mg in the bottle, we can determine how many days it will last by dividing this number by the total daily dosage:

Days = Total medication in bottle / Daily dosage Days = 7500 mg / (3 doses * 250mg) Days = 7500mg /750mg Days =10

Therefore, the bottle of medication will last for 10 days.

Correct Answer is ["12","000"]

Explanation

Here's the calculation for how many heparin units the client will receive in 12 hours:

Heparin concentration: The concentration of the heparin solution is 20,000 units in 500 mL (given). This translates to 40 units/mL (concentration = total units / volume).

Infusion rate: The client is receiving the solution at a rate of 25 mL/hour (given).

Time: We need to find the total heparin units received over 12 hours.

Calculation:

Find the total volume of the solution infused in 12 hours:

Total volume (mL) = Rate (mL/hour) x Time (hours)

Total volume (mL) = 25 mL/hour x 12 hours

Total volume (mL) = 300 mL

Find the total heparin units delivered in the infused volume:

Total heparin units = Volume of solution (mL) x Concentration (units/mL)

Total heparin units = 300 mL x 40 units/mL

Total heparin units = 12,000 units

Therefore, the client will receive 12,000 units of heparin in 12 hours.
