Question 1

The physician ordered a patient/client to receive 1000 mL D5 $1 / 2$ NS to infuse over 24 hours. Which solution should the nurse obtain from the supply car

Accepted Answer

D5 $1 / 2$ NS refers to a solution of 5% dextrose in 0.45% normal saline, which matches option C, D5% 0.45 NS.

Question 2

The faculty member tells the nursing student to obtain an IV microdrip tubing set. What is the drop factor on an IV microdrip?

Accepted Answer

There are three standard macrodrip IV tubing sets that deliver either 10 gtt/mL, 15 gtt/mL, or 20 gtt/mL. Microdrip IV tubing sets deliver 60 gtt/mL.

Question 3

The physician has ordered 1000 mL D5W, IV to run at 75 mL/hour. What is the correct volume for infusion and rate for infusion on the infusion pump?

Accepted Answer

When an order reads 1000 mL D5W to run at 75 mL/hour, the volume for infusion is 1000 mL, and the rate for infusion is 75 mL. The order would read 75 mL to run at 1000 mL/hour for a rate of infusion at 1000 mL and volume for infusion of 75 mL. The order would read 75 mL to run at 75 mL/hour for a rate of infusion at 75 mL and volume for infusion of 75 mL. The order would read 1000 mL at 1000 mL for a rate of infusion at 1000 mL and volume for infusion of 1000 mL.

Question 4

The physician ordered Vancomycin (vancomycin hydrochloride) 500 mg IVPB every 24 hours. The medication was placed in 100 mL of D5W to infuse over 60 minutes. What is the correct volume for infusion and rate for infusion on the infusion pump that has a microdrip tubing?

Accepted Answer

An infusion pump can be used for intravenous piggyback (IVPB). The order reads "medication was placed in 100 mL of D5W to infuse over 60 minutes." The nurse would enter two pieces of information into the pump: the total number of milliliters to be infused (100 mL) and the number of milliliters per hour. The infusion pump always uses a microdrip tubing (60 gtt/mL). Therefore, the pump will deliver 100 mL/hour. You can also use this formula to estimate milliliters per hour: total number of milliliters ordered/Number of hours to run. Therefore, 100 mL/1 hour (60 minutes) = 100 mL/hour. The secondary volume is 100 mL, and the secondary rate is 100 mL/hour. The pump interrupts the primary IV to administer the IVPB over 1 hour and then resumes the primary flow. The other choices are not correctly written orders or settings.

Question 5

What information is missing from this IV label?
10:00 am, Jane Doe, 1000 mL D5W at 100 mL/hr or 17 gtt/min, AB (initials).

Accepted Answer

The missing information is date, room, and bed number. Every IV must be identified so that any professional can check both the fluid that is hanging and the drip rate. A typical order includes the following information: patient/client name, order, room and bed number, date and time, rate of infusion, and initials of the nurse who hung the IV.

Question 6

The physician ordered D5 NS to run at 125 mL/hour with a drop factor of 20 gtt/mL. Calculate the IV flow rate in gtt/minute. Round off to the nearest whole number.

Accepted Answer

Use this formula: Number of milliliters to infuse F1F1F1S1?F1F1F10 TF/Number of minutes to infuse = Drops per minute or gtt/minute. Therefore, 125 mL F1F1F1S1?F1F1F10 20 gtt/mL ÷ 60 minutes = 2500/60 = 41.66 gtt/minute. Round off to the nearest whole number: 42 gtt/minute.

Question 7

The physician ordered 500 mL NS to run over 6 hours with a drop factor of 20 gtt/mL. Calculate the correct IV flow rate to set on the infusion pump.

Accepted Answer

Infusion pumps are always calculated in milliliters per hour. Use this formula: Total number of milliliters ordered/Number of hours to run = mL/hour. Therefore, 500 mL/6 hours = 83.33 mL/hour. Round off to the nearest whole number: 83 mL/hour.

Question 8

The physician ordered a unit of 250 mL packed red blood cells to infuse over 4 hours with a drop factor of 10 gtt/mL. Calculate the correct IV flow rate in milliliters per hour. Round off to the nearest whole number.

Accepted Answer

This IV order for packed red blood cells specifies the total amount of fluid to be infused and the duration of administration. To calculate milliliters per hour, simply divide the total volume (250 mL) by the number of hours (4 hours). Therefore, 250 mL/4 hours = 62.5 mL. Round off to the nearest whole number: 63 mL/hour.

Question 9

The physician ordered 1000 mL NS to infuse over 10 hours with a drop factor of 15 gtt/mL. Calculate the correct IV flow rate in drops per minute. Round off to the nearest whole number.

Accepted Answer

Use this formula: Number of milliliters to infuse F1F1F1S1?F1F1F10 TF/Number of minutes to infuse = Drops per minute or gtt/minute. Therefore, 1000 mL F1F1F1S1?F1F1F10 15 gtt/mL ÷ 600 minutes (10 hours F1F1F1S1?F1F1F10 60 minutes) = 15,000/600 = 24.9 gtt/minute. Round off to the nearest whole number: 25 gtt/minute.

Question 10

The physician ordered 1000 mL of D5W to infuse at 125 mL/hour with a drop factor of 10 gtt/mL. How many hours will this IV run?

Accepted Answer

This IV order specifies the total amount of fluid to be infused and the amount to be given per hour (milliliters per hour). To calculate the duration of infusion (number of hours), simply divide the total volume (1000 mL) by the volume per hour (125 mL). Therefore, 1000 mL ÷ 125 mL/hour = 8 hours to infuse.

Question 11

The physician ordered a total of 1500 mL of NS to infuse at 75 mL/hour with a drop factor of 15 gtt/mL. How many hours will this IV run?

Accepted Answer

This IV order specifies the total amount of fluid to be infused and the amount to be given per hour (milliliters per hour). To calculate the duration of infusion (number of hours), simply divide the total volume (1500 mL) by the volume per hour (75 mL). Therefore, 1500 mL ÷ 75 mL/hour = 20 hours to infuse.

Question 12

The physician ordered 1000 mL of D5W to infuse over 16 hours with a drop factor of 20 gtt/mL. Calculate the correct IV flow rate in drops per minute. Round off to the nearest whole number.

Accepted Answer

Use this formula: Number of milliliters to infuse F1F1F1S1?F1F1F10 TF/Number of minutes to infuse = Drops per minute or gtt/minute. Therefore, 1000 mL F1F1F1S1?F1F1F10 20 gtt/mL ÷ 960 minutes (16 hours F1F1F1S1?F1F1F10 60 minutes) = 20,000/960 = 20.8 gtt/minute. Round off to the nearest whole number: 21 gtt/minute.

Question 13

The physician ordered 2500 mL of NS to infuse in 150 mL/hour with a drop factor of 15 gtt/mL. How long will this IV run?

Accepted Answer

A routine IV order specifies the total amount of fluid to be infused and the amount to be given per hour (milliliters per hour). To calculate the duration of infusion (number of hours), simply divide the total volume (2500 mL) by the volume per hour (150 mL). Therefore, 2500 mL ÷ 150 mL/hour = 16.6 hours to infuse. The next step requires that you convert the 0.6 hour to minutes. Multiply: 0.6 * 60 minutes = 36 minutes. Therefore, the answer is 16 hours and 36 minutes.

Question 14

An IV infusion pump is not available. The nurse would use a macrodrip for the IV infusion in which instance?

Accepted Answer

A macrodrip is used when the order specifies a large amount of fluid over a short time. A microdrip is used when the IV is to be administered over a long period, a small amount of fluid is to be infused, or the macrodrops per minute are too few.

Question 15

The physician ordered 1000 mL, D5 $1 / 2$ NS with KCL 10 mEq IV over 8 hours. The nurse located a vial of potassium chloride 40 mEq/20 mL. How many milliliters of KCL should the nurse add to theZV bag?

Accepted Answer

The order is for 10 mEq of KCL. The concentration of the KCL solution is 40 mEq in 20 mL. To find out how many mL are needed for 10 mEq, you set up a proportion: $40 \, \text{mEq} : 20 \, \text{mL} = 10 \, \text{mEq} : x \, \text{mL}$. Solving for $x$, you get $x = \frac{10 \, \text{mEq} \times 20 \, \text{mL}}{40 \, \text{mEq}} = 5 \, \text{mL}$.

Question 16

The physician ordered 250 mL D5 $1 / 2$ NS with aminophylline 0.25 g added for administration over 1 hour, every 6 hours. The nurse located a vial of aminophylline 500 mg/20 mL. How many milliliters of medication should be added to the IV bag?

Accepted Answer

To find out how many milliliters of aminophylline should be added, first convert 0.25 g to mg, which is 250 mg. The concentration of aminophylline is 500 mg in 20 mL. To find out how many mL contain 250 mg, set up a proportion: (500 mg / 20 mL) = (250 mg / x mL). Solving for x gives x = 10 mL.

Question 17

The physician ordered clindamycin (Cleocin) 900 mg in 75 mL over 30 minutes with a drop factor of 15 gtt/mL. What is the correct IV flow rate in drops per minute? Use both the standard formula and dimensional analysis to solve this problem. Round off to the nearest whole number.

Accepted Answer

For IV piggyback problems, use the standard calculation formula used for IVs: Milliliters * TF/Minutes = gtt/minute. Therefore, 75 mL * 15 gtt/mL ÷ 30 minutes = 1125/30 = 37.5 gtt/minute; round off to 38 gtt/minute. Use this formula for dimensional analysis: gtt/mL *mL/minute. Therefore, 15 gtt/1 mL *75 mL/30 minutes = 15 gtt * 75/1 * 30 = 1125 gtt/30 minutes = 37.5 gtt/minute; round off to 38 gtt/minute.

Question 18

The physician has ordered Tagamet (cimetidine) 300 mg in 50 mL D5W over 30 minutes with a drop factor of 10 gtt/mL. What is the correct IV flow rate in drops per minute? Use both the standard formula and dimensional analysis to solve this problem. Round off to the nearest whole number.

Accepted Answer

For IV piggyback problems, use the standard calculation formula used for IVs: Milliliters *TF/Minutes = gtt/minute. Therefore, 50 mL *10 gtt/mL ÷ 30 minutes = 500/30 = 16.6 gtt/minute; round off to 17 gtt/minute. Use this formula for dimensional analysis: gtt/mL * mL/minute. Therefore, 10 gtt/1mL * 50 mL/30 minutes = 10 gtt * 50/1 * 30 minutes = 500/30 =16.6 gtt/minute; round off to 17 gtt/minute.

Question 19

The physician ordered $3 / 4$
 -strength Ensure. The total volume is 240 mL. How many milliliters of Ensure should be mixed with the water

Accepted Answer

To find the amount of Ensure needed, multiply the total volume by the strength fraction: $240 \, \text{mL} \times \frac{3}{4} = 180 \, \text{mL}$.

Question 20

The physician has ordered $1 / 4$ -strength Isocal. The total volume is 100 mL. How many milliliters of water need to be mixed with the Isocal

Accepted Answer

To make a $1 / 4$-strength solution, you mix one part Isocal with three parts water. For a total volume of 100 mL, this means 25 mL Isocal and 75 mL water.
