Question 1: View

The order from a provider is: Administer 3 liters of DSLR over 24hrs. Drop factor is 15 gtt/mL. How many gtt/min will be administered?

Explanation

The nurse should set the IV infusion to deliver 31 gtt/min.

Let's calculate the drip rate

Understanding the problem

We need to administer 3 liters (3000 mL) of DSLR over 24 hours.

The drop factor is 15 gtt/mL.

We need to find the drip rate in gtt/min.

Step-by-step calculation

Convert hours to minutes:

24 hours = 24 X 60 minutes = 1440 minutes

Calculate the infusion rate in mL/min:

Infusion rate (mL/min) = Total volume (mL) / Total time (min)

Infusion rate = 3000 mL / 1440 min = 2.0833 mL/min

Calculate the drip rate:

Drip rate (gtt/min) = Infusion rate (mL/min) X Drop factor (gtt/mL)

Drip rate = 2.0833 mL/min X 15 gtt/mL = 31.25 gtt/min

Round the drip rate to the nearest whole number:

Drip rate ≈ 31 gtt/min

The nurse should set the IV infusion to deliver 31 gtt/min.

Question 2: View

A nurse is preparing to administer Reglan (metoclopramide) 15 mg PO QID before meals and at bedtime for a client who has GERD. The amount available is metoclopramide 5 mg/5mL. How many mL should the nurse administer?

Explanation

The nurse should administer 15 mL of metoclopramide.

Let's calculate the volume of Reglan to administer.

Understanding the problem:

Desired dose: 15 mg

Available concentration: 5 mg/5 mL

Calculations:

We can set up a proportion to solve for the unknown volume (x):

5 mg / 5 mL = 15 mg / x mL

Cross-multiply:

5x = 75

Solve for x:

x = 75 / 5

x = 15 mL

The nurse should administer 15 mL of metoclopramide.

Question 3: View

A client is on a fluid restriction of 1.2 liters per day. How many milliliters per hour is the patient allowed?

Explanation

Understanding the Problem

The patient is restricted to 1.2 liters of fluid per day.

We need to find the fluid restriction in milliliters per hour.

Calculations

Convert liters to milliliters:

1 liter = 1000 milliliters

So, 1.2 liters = 1.2 X 1000 = 1200 milliliters

Calculate milliliters per hour:

There are 24 hours in a day.

So, the patient is allowed 1200 milliliters / 24 hours = 50 milliliters/hour.

The patient is allowed 50 milliliters per hour.

Question 4: View

The order from a provider is: Administer D5W @ 25 mL/hr. The drip factor is 60 gtt/mL. How many gtt/min?

Explanation

Understanding the Problem

We need to administer D5W at a rate of 25 mL/hour.

The drip factor is 60 gtt/mL.

We need to find the drip rate in gtt/min.

Calculations

Convert hours to minutes:

1 hour = 60 minutes

Calculate the infusion rate in mL/min:

25 mL/hour = 25 mL / 60 minutes = 0.4167 mL/min

Calculate the drip rate:

Drip rate (gtt/min) = Infusion rate (mL/min) X Drop factor (gtt/mL)

Drip rate = 0.4167 mL/min X 60 gtt/mL = 25 gtt/min

The drip rate is 25 gtt/min.

Question 5: View

The order from a provider is: Infuse a unit of whole blood over 2 hours. Blood bank provides you a unit of whole blood product that is 250 mL in volume. The drop factor of the filter tubing is 10 gtt/mL. How many gtt/min will be administered?

Explanation

Step-by-Step Calculation

Understanding the Problem

We need to infuse 250 mL of whole blood over 2 hours.

The drop factor is 10 gtt/mL.

We need to calculate the drip rate in gtt/min.

Calculations

Convert hours to minutes:

2 hours = 2 X 60 minutes = 120 minutes

Calculate the infusion rate in mL/min:

Infusion rate (mL/min) = Total volume (mL) / Total time (min)

Infusion rate = 250 mL / 120 min = 2.0833 mL/min

Calculate the drip rate:

Drip rate (gtt/min) = Infusion rate (mL/min) X Drop factor (gtt/mL)

Drip rate = 2.0833 mL/min X 10 gtt/mL = 20.83 gtt/min

Round the drip rate to the nearest whole number:

Drip rate ≈ 21 gtt/min

The nurse should set the IV infusion to deliver 21 gtt/min.

Question 6: View

The order from a provider is to start a Heparin drip at 1600 units per hour. The pharmacy provides you with a concentration of heparin that is 250mL NS with 40,000 units of Heparin added. What will be the rate on the infusion pump?

Explanation

Step-by-Step Calculation

Understanding the Problem

Desired heparin dose: 1600 units/hour

Heparin concentration: 40,000 units in 250 mL NS

We need to find the infusion rate in mL/hour.

Calculations

Calculate heparin concentration:

Heparin concentration = Total units / Total volume

Heparin concentration = 40,000 units / 250 mL = 160 units/mL

Calculate infusion rate:

Infusion rate (mL/hour) = Desired heparin dose (units/hour) / Heparin concentration (units/mL)

Infusion rate = 1600 units/hour / 160 units/mL = 10 mL/hour

The infusion pump rate should be set to 10 mL/hour.

Question 7: View

The order from a provider is: Phenergan (Promethazine) 50 mg in 30 mL of d5W IV q8h to be administered over 20 min PRN for nausea. What is the rate on the Infusion pump?

Explanation

Step-by-Step Calculation

Understanding the Problem

We need to administer 30 mL of Phenergan in D5W over 20 minutes.

We need to find the infusion rate in mL/hour.

Calculations

Convert minutes to hours:

20 minutes = 20/60 hours = 1/3 hour

Calculate the infusion rate:

Infusion rate (mL/hour) = Total volume (mL) / Time (hours)

Infusion rate = 30 mL / (1/3 hour) = 30 mL X 3 = 90 mL/hour

The infusion pump rate should be set to 90 mL/hour.

Question 8: View

A nurse is caring for a client who has diabetes and a prescription for 14 units of regular insulin and 28 units of NPH insulin subcutaneously at breakfast daily. What is the total number of units of insulin that the nurse should prepare in the insulin syringe?

Explanation

Total Insulin Units

Regular insulin: 14 units

NPH insulin: 28 units

Total insulin: 14 units + 28 units = 42 units

The nurse should prepare 42 units of insulin in the syringe.

Question 9: View

The order from a provider is: Start Pitocin (Oxytocin) at 5 milliunits/min to induce labor. The pharmacy provides you with a 200 mL bag with 20 units of Pitocin added. What is the rate on the infusion pump?

Explanation

Step-by-Step Calculation

Understanding the Problem

Desired Pitocin dose: 5 milliunits/min

Pitocin concentration: 20 units in 200 mL

We need to find the infusion rate in mL/hour.

Calculations

Convert milliunits to units:

5 milliunits/min = 0.005 units/min

Calculate units per hour:

0.005 units/min X 60 min/hour = 0.3 units/hour

Calculate the concentration of Pitocin:

Pitocin concentration = Total units / Total volume

Pitocin concentration = 20 units / 200 mL = 0.1 units/mL

Calculate the infusion rate:

Infusion rate (mL/hour) = Desired Pitocin dose (units/hour) / Pitocin concentration (units/mL)

Infusion rate = 0.3 units/hour / 0.1 units/mL = 3 mL/hour

The infusion pump rate should be set to 3 mL/hour.

Question 10: View

The order from a provider is: Infuse 600 mL of NS over 8 hours. What will be the rate on the infusion pump?

Explanation

Step-by-Step Calculation

Understanding the Problem

We need to infuse 600 mL of Normal Saline (NS) over 8 hours.

We need to find the infusion rate in mL/hour.

Calculations

Infusion rate (mL/hour) = Total volume (mL) / Time (hours)

Infusion rate = 600 mL / 8 hours = 75 mL/hour

The infusion pump rate should be set to 75 mL/hour.
