RELIAS RN BASIC MATH ABILITY EXAM
With Correct Answers (2026/2027 Edition)
Question 1
The physician orders 1,500 mg of a medication to be given over 90 minutes. The
available medication is 1,500 mg/250 mL. You will set the pump to deliver how many
mL/hr? (Round to the nearest whole number)
Answer: 167 mL/hr
Explanation:
First convert 90 minutes to hours, which equals 1.5 hours. Since 250 mL must infuse
over 1.5 hours, divide 250 by 1.5. This results in 166.7 mL/hr, which rounds to 167
mL/hr. Pump rates are always expressed in mL/hr.
Question 2
Your patient is receiving 37.5 mcg of a medication. This is equivalent to how many
mg? (Record your answer using two decimal places)
Answer: 0.04 mg
Explanation:
There are 1,000 micrograms in 1 milligram. Divide 37.5 mcg by 1,000 to convert to
milligrams. The result is 0.0375 mg, which rounds to 0.04 mg when using two decimal
places.
,Question 3
The surgeon orders a medication 1.5 grams IV. The pharmacy delivers the medication
as 1.5 grams in 150 mL IV solution to be infused over 90 minutes. The rate of infusion
is how many mL/hr?
Answer: 100 mL/hr
Explanation:
Convert 90 minutes into hours by dividing by 60, which equals 1.5 hours. The total
volume of 150 mL must infuse over 1.5 hours. Dividing 150 by 1.5 gives a rate of 100
mL/hr.
Question 4
The patient is to receive 1,000 mL of IV fluids over 8 hours. The IV set delivers 15
gtts/mL. The drip rate will be how many gtts/min? (Round to the nearest whole
number)
Answer: 31 gtts/min
Explanation:
First determine mL/hr by dividing 1,000 mL by 8 hours, which equals 125 mL/hr.
Multiply 125 mL/hr by the drop factor of 15 gtts/mL. Then divide by 60 minutes to
convert to drops per minute, resulting in 31.25 gtts/min, which rounds to 31.
Question 5
An IV piggyback of 10,000 units in 100 mL is to be infused over 45 minutes. The pump
should be programmed to deliver how many mL/hr? (Round to the nearest whole
number)
Answer: 133 mL/hr
Explanation:
Convert 45 minutes to hours by dividing by 60, which equals 0.75 hours. Divide the
total volume (100 mL) by 0.75 hours. This equals 133.3 mL/hr, which rounds to 133
mL/hr.
Question 6
,The physician orders 0.3 g of a drug every 12 hours orally. The drug is available in 150
mg caplets. How many caplets should the nurse administer?
Answer: 2 caplets
Explanation:
Convert grams to milligrams by multiplying 0.3 g by 1,000, which equals 300 mg. Each
caplet contains 150 mg. Dividing 300 mg by 150 mg per caplet results in 2 caplets.
Question 7
The physician has ordered 60 grams of a medication. On hand, the medication is
available at 15 grams per 30 mL. How many mL will you administer?
Answer: 120 mL
Explanation:
Set up a proportion using the available concentration. If 15 grams are contained in 30
mL, then 60 grams will be four times that amount. Multiply 30 mL by 4 to obtain 120
mL.
Question 8
The physician has ordered 85 mg IV push. The pharmacy has dispensed 125 mg per 2
mL. How many mL should the nurse administer? (Record your answer using one
decimal place)
Answer: 1.4 mL
Explanation:
First determine how many mg are in 1 mL by dividing 125 mg by 2 mL, which equals
62.5 mg/mL. Then divide the ordered dose (85 mg) by 62.5 mg/mL. This equals 1.36
mL, which rounds to 1.4 mL.
Question 9
A provider orders 500 mg of a medication. The drug is supplied as 250 mg tablets.
How many tablets should be administered?
Answer: 2 tablets
, Explanation:
The ordered dose is 500 mg and each tablet contains 250 mg. Dividing 500 mg by 250
mg per tablet gives 2 tablets. Always confirm that tablets may be split before altering
doses.
Question 10
An IV infusion of 1,200 mL is ordered over 12 hours. What is the infusion rate in mL/hr?
Answer: 100 mL/hr
Explanation:
Divide the total volume by the total time in hours. When 1,200 mL is infused over 12
hours, the rate equals 100 mL/hr. This rate is appropriate for standard IV pumps.
Question 11
A medication order reads 0.75 g IV. The vial is labeled 250 mg/mL. How many mL
should be administered?
Answer: 3 mL
Explanation:
Convert grams to milligrams by multiplying 0.75 g by 1,000, giving 750 mg. Each
milliliter contains 250 mg. Dividing 750 mg by 250 mg/mL results in 3 mL.
Question 12
A patient weighing 70 kg is prescribed a medication at 5 mg/kg/day. What is the total
daily dose?
Answer: 350 mg/day
Explanation:
Multiply the patient’s weight by the prescribed dose per kilogram. Seventy kilograms
multiplied by 5 mg/kg equals 350 mg per day. This dose may be divided depending on
the dosing schedule.
