HESI A2 Math Practice Exam Questions
Question 1 of 5
What is the boiling point of water?
Correct Answer: A
Rationale: Failed to generate a rationale after 5 retries.
Question 2 of 5
The price of an item increased from $9.00 to $10.00. What percentage did the price increase by?
Correct Answer: B
Rationale: To calculate the percentage increase, subtract the initial price ($9.00) from the final price ($10.00) to get the increase ($1.00). Then, divide the increase by the initial price ($1.00 / $9.00 = 0.1111). Convert the result to a percentage by multiplying by 100, giving 11.11%. Choice B (11.11%) is correct. Choice A (5%) is incorrect because the increase is $1.00, not $0.45. Choice C (20%) and Choice D (25%) are also incorrect as they do not accurately reflect the calculated percentage increase of 11.11%.
Question 3 of 5
The physician ordered 3,000 units of heparin; 5,000 U/mL is on hand. How many milliliters will you give?
Correct Answer: B
Rationale: To calculate the volume needed, use the formula: Volume (ml) = Required dose (units) / Concentration (U/ml). In this case, Volume = 3,000 units / 5,000 U/ml = 0.6 ml. Therefore, the correct answer is B (0.6 ml). Choice A is incorrect because it underestimates the volume needed. Choices C and D are incorrect as they overestimate the volume required based on the calculation.
Question 4 of 5
How many ounces are in 3 pints?
Correct Answer: B
Rationale: To convert pints to ounces, we know that 1 pint is equal to 16 ounces. Therefore, 3 pints would be 3 x 16 = 48 ounces. This makes choice B the correct answer. Choice A (24 ounces) is incorrect as it represents only 1 pint, not 3. Choice C (32 ounces) and choice D (64 ounces) are also incorrect as they do not accurately reflect the conversion of pints to ounces.
Question 5 of 5
If a dozen roses cost $36, how much will four roses cost?
Correct Answer: B
Rationale: To find the cost of 4 roses, we divide the total cost of 12 roses by 12 to get the cost of 1 rose ($36 / 12 = $3). Then, we multiply the cost of 1 rose by 4 to find the cost of 4 roses ($3 * 4 = $12). Therefore, the correct answer is B. Choice A ($9) is incorrect as it assumes a linear relationship between the number of roses and the cost, which is not the case. Choice C ($10) and Choice D ($15) are also incorrect as they do not follow the correct calculation method.
