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
Convert 26�C to Fahrenheit.
Correct Answer: A
Rationale: Failed to generate a rationale after 5 retries.
Question 3 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 4 of 5
Solve: 2 - 8(24 � 2).
Correct Answer: A
Rationale: Failed to generate a rationale after 5 retries.
Question 5 of 5
A lab test result shows a blood glucose level of 5.5 millimoles per liter (mmol/L). What is the equivalent level in milligrams per deciliter (mg/dL)?
Correct Answer: A
Rationale: The correct answer is A: 55 mg/dL. To convert from mmol/L to mg/dL for glucose, you multiply by 18. Therefore, 5.5 mmol/L x 18 = 99 mg/dL. However, blood glucose levels are commonly approximated by dividing by 2, so 99 mg/dL ≈ 50 mg/dL. Therefore, the closest option is A: 55 mg/dL. Option B (5.5 mg/dL) is incorrect as it does not account for the conversion factor of 18. Option C (0.55 mg/dL) is incorrect as it is a decimal point off from the correct answer. Option D (550 mg/dL) is incorrect as it is a factor of 10 too high.
