HESI A2 Math Exam – Set 1
1. A roast was cooked at 325°F in the oven for 4 hours. The internal temperature rose from
32°F to 145°F. What was the average rise in temperature per hour?
A. 20.2°F/hr
B. 32.03°F/hr
C. 28.25°F/hr
D. 37°F/hr
Correct Answer: C. 28.25°F/hr
Step-by-Step Rationale:
Formula:
Average rise per hour = Total temperature rise ÷ Total hours
Calculation:
145°F − 32°F = 113°F
113°F ÷ 4 hours = 28.25°F/hr
Therefore, the average rise in temperature per hour is 28.25°F/hr.
2. Your supervisor instructs you to purchase 240 pens and 6 staplers for the nurse’s station.
Pens are purchased in sets of 6 for $2.35 per pack. Staplers are sold in sets of 2 for $12.95.
How much will purchasing these products cost?
A. $162.90
B. $132.85
C. $225.05
D. $145.75
Correct Answer: B. $132.85
Step-by-Step Rationale:
Pens:
240 ÷ 6 = 40 packs
,40 × $2.35 = $94.00
Staplers:
6 ÷ 2 = 3 packs
3 × $12.95 = $38.85
Total cost:
$94.00 + $38.85 = $132.85
Therefore, the total cost is $132.85.
3. Which of the following percentages is equal to 0.45?
A. 0.45%
B. 0.045%
C. 4.5%
D. 45%
Correct Answer: D. 45%
Step-by-Step Rationale:
Formula:
Decimal × 100 = Percent
Calculation:
0.45 × 100 = 45%
Therefore, 0.45 equals 45%.
4. A vitamin’s expiration date has passed. It was supposed to contain 500 mg of Calcium, but it
has lost 325 mg of Calcium. How many mg of Calcium is left?
A. 175 mg
B. 135 mg
C. 185 mg
D. 200 mg
Correct Answer: A. 175 mg
Step-by-Step Rationale:
Formula:
Amount left = Original amount − Amount lost
Calculation:
500 mg − 325 mg = 175 mg
, Therefore, 175 mg of Calcium is left.
5. You have orders to give a patient 20 mg of a certain medication. The medication is stored as
4 mg per 5-mL dose. How many milliliters will need to be given?
A. 30 mL
B. 25 mL
C. 20 mL
D. 15 mL
Correct Answer: B. 25 mL
Step-by-Step Rationale:
Formula:
Required mL = Ordered dose ÷ Available dose × Available mL
Calculation:
20 mg ÷ 4 mg = 5 doses
5 × 5 mL = 25 mL
Therefore, the patient should receive 25 mL.
6. In the number 743.25, which digit represents the tenths place?
A. 3
B. 4
C. 2
D. 5
Correct Answer: C. 2
Step-by-Step Rationale:
The tenths place is the first digit to the right of the decimal point.
In 743.25, the first digit after the decimal is 2.
Therefore, the tenths digit is 2.
7. Which of these percentages equals 1.25?
A. 1250%
B. 0.125%
C. 12.5%
D. 125%
