The primary health care provider (PHCP) prescribes ondansetron 0.15 mg/kg IV to a pediatric client who weighs 18.18 kg (39.99 lbs). The medication label reads 2 mg/mL.

How many milliliters will the nurse administer to the client? Fill in the blank. Round your answer using 1 decimal place.

Answer explanation

The formula of dose ordered / dose on hand x volume will be utilized to solve this multistep problem.

First, determine the prescribed dose.

0.15 mg x 18.18 kg = 2.72 mg

Next, take the dose ordered / dose on hand x volume.

2.72 mg / 2 mg x 1 mL = 1.36 mL

Finally, round the answer using 1 decimal place.

1.36 mL = 1.4 mL

The primary healthcare provider (PHCP) prescribes 400,000 units of penicillin G benzathine. The label on the medication reads penicillin G benzathine 300,000 units / 10 mL.

How many milliliters will the nurse administer to the client? Fill in the blank. Round your answer to the nearest whole number.

Answer explanation

The formula of dose ordered / dose on hand x volume will be utilized to solve this problem.

Divide the prescribed amount of medication by what is on hand.

400,000 units / 300,000 units = 1.3 mL

Next, take the amount of the medication and multiply it by the volume.

1.3 mL x 10 mL = 13.3 mL

Finally, take the dosage and round to the nearest whole number.

13.3 mL = 13 mL

The primary healthcare provider (PHCP) prescribes a regular insulin infusion for a client with diabetic ketoacidosis (DKA). The prescription is for 2 units/hr. The label on the medication reads 250 mL of 0.9% saline containing 100 units of regular insulin.

How many mL/hr should the client receive? Fill in the blank. Round your answer to the nearest whole number.

Answer explanation

The formula of dose ordered / dose on hand x volume will be utilized to solve this problem.

Divide the prescribed amount of medication by what is on hand.

2 units / 100 units = 0.02 units

Next, take the amount of the medication and multiply it by the volume.

0.02 units x 250 mL = 5 mL/hr

The primary healthcare provider prescribes 30 mL/kg of 0.9% saline to a client with suspected sepsis who weighs 107.27 kg (235.99 lbs).

How many mL will the nurse administer to the client? Fill in the blank. Round your answer to the nearest whole number.

Answer explanation

Multiply the prescribed amount of fluid by the client's weight in kilograms.

30 mL x 107.27 kg = 3218.1 mL

Next, round the amount of fluid to a whole number.

3218 mL

The primary healthcare provider (PHCP) prescribes dopamine at 2.5 mcg/kg/minute. The client weighs 90 kg (198 lbs). The medication label reads dopamine 800 mg in 500 mL of dextrose 5% water (D5W).

How many mL per hour will be administered to the client? Fill in the blank. Round your answer to the nearest whole number.

Answer explanation

To solve this multistep problem, the formula of dose ordered / dose on hand x volume will be used.

First, determine the hourly dosage.

2.5 mcg x 90 kg x 60 minutes = 13500 mcg

Next, convert the micrograms to milligrams.

13500 mcg / 1000 mg = 13.5 mg

Next, divide the dose ordered by the amount on hand x the volume.

13.5 mg / 800 mg x 500 mL = 8.43 mL/hr

Finally, round the answer to the nearest whole number.

8.43 mL/hr = 8 mL/hr

The primary healthcare provider (PHCP) prescribes 0.375 mg of digoxin intravenously (IV) to a client. The nurse has 0.25 mg/mL of digoxin on hand.

How many mL will the nurse administer? Fill in the blank. Record your answer using 1 decimal place.

Answer explanation

To solve this problem, the formula of dose ordered / dose on hand will be utilized.

0.375 mg is ordered so that will be divided by the amount on hand of 0.25 mg/mL

0.375 / 0.25 = 1.5 mL

1.5 mL

The primary healthcare provider (PHCP) prescribes 250 mL of 0.9% saline to infuse over 75 minutes.

How many mL per hour will be administered to the client? Fill in the blank.

Answer explanation

To solve this problem, the formula of volume / time (hours) will be used.

First, convert the minutes to hours.

75 minutes / 60 minutes = 1.25 hrs

Next, divide the prescribed total volume by the infusion time.

250 mL / 1.25 hours = 200 mL/hr

The primary healthcare provider (PHCP) prescribes 100 mL of 0.9% saline to infuse over 45 minutes.

How many mL per hour will the nurse administer to the client? Fill in the blank. Round your answer to the nearest whole number.

Answer explanation

To solve this problem, the formula of volume / time (hours) will be used.

First, convert the minutes to hours.

45 minutes / 60 minutes = 0.75 hrs

Next, divide the prescribed total volume by the infusion time.

100 mL / 0.75 hours = 133.33

Finally, take the mL/hour and round to the nearest whole number.

133.33 = 133 mL/hr

The nurse cares for a client receiving 1300 units/hr of heparin. The bag is labeled 25,000 units in 500 mL of dextrose 5% in water.

How many mL should the nurse record that the client received in eight hours? Fill in the blank.

Answer explanation

First, determine how many mL/hr the client is receiving (dose ordered / dose on hand x volume).

1300 units / 25000 units x 500 mL = 26 mL

Next, take the mL/hr the client is receiving and multiply it by 8.

26 mL x 8 hours = 208 mL

A nurse is preparing to administer vancomycin to a child. The order is for 50 mg/kg/day in three divided doses. The client weighs 13 kg (28.6 lbs). The medication label indicates vancomycin 500 mg in 100 mL of 0.9% saline.

How many mL will the nurse administer per dose? Fill in the blank. Round your answer to the nearest whole number.

Answer explanation

First, determine the total daily dose for this child (the child weighs 13 kg).

50 mg x 13 kg = 650 mg per day

Next, determine the individual dose. Divide the daily dose by 3.

650 mg/day / 3 doses/day = 216.66 mg

Next, divide the prescribed dose by the dose on hand x volume.

216.66 / 500 mg x 100 mL = 43.32 mL

Finally, round your answer to the nearest whole number.

43.32 mL = 43 mL
