A client returns from the PACU with a bag of 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"]

To find the answer, we can use the following steps:

- Calculate the infusion rate in mL/hour by dividing the volume of IV fluids by the time of infusion

- Calculate the infusion rate in mL/minute by dividing the infusion rate in mL/hour by 60

- Multiply the infusion rate in mL/minute by the drop factor in gtt/mL to get the infusion rate in gtt/minute

- Round the result to the nearest whole number

Using these steps, we get:

- (infusion rate in mL/hour) = (630) / (7) = 90 mL/hour

- (infusion rate in mL/minute) = (90) / (60) = 1.5 mL/minute

- (infusion rate in gtt/minute) = (1.5) x (10) = 15 gtt/minute

- (rounded infusion rate in gtt/minute) = 15

Therefore, the nurse should regulate the infusion to deliver 15 gtt/minute of IV fluids to the client.

Correct Answer is ["6"]

Explanation

To find the answer, we can use the following steps:

- Convert the dosage of oxytocin from milliunits/min to units/hour by multiplying by 60

- Calculate the concentration of oxytocin in the IV bag by dividing the amount of oxytocin by the volume of solution

- Divide the dosage of oxytocin by the concentration of oxytocin in the IV bag to get the volume to be delivered

Using these steps, we get:

- (dosage of oxytocin in units/hour) = (2) x (60) = 120 milliunits/hour

- (concentration of oxytocin in IV bag) = (20) / (1000) = 0.02 units/mL

- (volume to be delivered in mL/hour) = (120 x 10^-3) / (0.02) = 6 mL/hour

Therefore, the nurse should program the infusion pump to deliver 6 mL/hour of oxytocin in lactated Ringer's to the patient.

Correct Answer is ["1"]

Explanation

First, we need to find out how many mg of warfarin are in one vial. Since the vial is labeled 5 mg/single-use, we can assume that it contains 5 mg of warfarin.

Next, we need to find out how many mL of solution are in one vial. Since the instructions say to reconstitute with 2.7 mL of sterile water for injection to yield 2 mg/mL, we can use the following formula:

Amount of solution= amount of water + amount of warfarin

Substituting the given values, we get:

Amount of solution = 2.7 + 5 =7.7 mL

Now, we need to find out how many mL of solution contain 2 mg of warfarin, which is the prescribed dose for the patient. We can use the following formula:

mL of solution = mg of warfarin/ concentration of warfarin

Substituting the given values, we get:

mL of solution = 2/2 = 1 mL

Therefore, the nurse should administer 1 mL of solution to the patient.
