HESI A2 Practice Test Math Questions

Question 1 of 5

A patient needs to take 2 tablets for every 30 pounds of body weight. If they weigh 150 pounds, how many tablets should they take?

Correct Answer: B

Rationale: To calculate the number of tablets needed, we divide the patient's weight by 30 (150/30 = 5). Then, we multiply the result by 2 since they need 2 tablets per 30 pounds (5 x 2 = 10). Therefore, the correct answer is B (10 tablets). Choice A is incorrect as it does not account for the weight calculation. Choices C and D are incorrect as they do not consider the dosage requirement based on the patient's weight.

Question 2 of 5

What is the result of the expression 4/5 + 6/7?

Correct Answer: A

Rationale: To solve 4/5 + 6/7, find a common denominator: 35. 4/5 = 28/35 and 6/7 = 30/35. Adding these gives 28/35 + 30/35 = 58/35 = 1 23/35. Therefore, the correct answer is A (1 23/35). The other choices are incorrect as they do not correctly calculate the sum of the fractions. B (2 5/7), C (1 1/7), and D (1 3/4) are not the result of the given expression.

Question 3 of 5

7:5=91:x. Find x.

Correct Answer: A

Rationale: To find x, first, find the ratio between the two parts of the equation: 7/5 = 91/x. Cross multiply to solve for x: 7x = 455. Divide by 7 to get x = 65 (Choice A). Choices B, C, and D are incorrect as they do not match the calculated value of x.

Question 4 of 5

Erin has 6.25 peach pies. She gives Rose 3.75 of the peach pies. How many pies does Erin have left?

Correct Answer: A

Rationale: First, determine how many peach pies Erin has left after giving 3.75 to Rose: 6.25 - 3.75 = 2.5 peach pies. Since she can't have half a pie, it rounds down to 2. So, Erin has 2 peach pies left, making option A the correct answer. Option B, C, and D are incorrect as they do not reflect the accurate calculation of the remaining pies.

Question 5 of 5

Solve for x: 3(x - 4) = 18.

Correct Answer: A

Rationale: To solve for x in the equation 3(x - 4) = 18, first distribute the 3: 3x - 12 = 18. Next, add 12 to both sides to isolate the variable: 3x = 30. Finally, divide by 3 to find x = 10. Choice A is correct because it correctly solves the equation step by step. Choices B, C, and D are incorrect as they do not follow the correct mathematical operations to solve for x.
