HESI A2 Math Questions

Question 1 of 5

A nurse administers 150mg of medication every 4 hours. How many milligrams will the patient receive in 24 hours?

Correct Answer: D

Rationale: To calculate the total medication received in 24 hours, we first find out how many doses will be given in 24 hours. Since a dose of 150mg is given every 4 hours, there will be 6 doses in 24 hours (24 hours / 4 hours per dose = 6 doses). Multiplying 150mg by 6 doses gives us 900mg, which is the correct answer (D). Choices A, B, and C are incorrect because they do not take into account the frequency of doses within the 24-hour period.

Question 2 of 5

A nurse administers 150mg of medication every 4 hours. How many milligrams will the patient receive in 24 hours?

Correct Answer: D

Rationale: To calculate the total medication received in 24 hours, we first find out how many doses will be given in 24 hours. Since a dose of 150mg is given every 4 hours, there will be 6 doses in 24 hours (24 hours / 4 hours per dose = 6 doses). Multiplying 150mg by 6 doses gives us 900mg, which is the correct answer (D). Choices A, B, and C are incorrect because they do not take into account the frequency of doses within the 24-hour period.

Question 3 of 5

What is the greatest common factor (GCF) of 12 and 18?

Correct Answer: C

Rationale: To find the GCF of 12 and 18, list the factors of each: 12: 1, 2, 3, 4, 6, 12; 18: 1, 2, 3, 6, 9, 18. The common factors are 1, 2, 3, and 6. The greatest common factor is the largest number that both 12 and 18 can be divided by without remainder, which is 6. Choice A (2) and B (3) are factors, but not the greatest common factor. Choice D (9) is a factor of 18 but not 12, so it cannot be the GCF.

Question 4 of 5

If Mr. Parker owns 150 shares of stock in Stark Industries and receives $180.00 per year in dividends, how much does Mr. Rogers receive for an annual dividend if he owns 400 shares?

Correct Answer: A

Rationale: To calculate the annual dividend Mr. Rogers receives for his 400 shares, we need to find the dividend per share first. For Mr. Parker, the dividend per share is $180/150 = $1.20. So, for Mr. Rogers, with 400 shares, his annual dividend would be 400 x $1.20 = $480. Therefore, the correct answer is A: $480. Summary: - B: $500 is incorrect because it is not the correct calculation based on the given information. - C: $450 is incorrect as it is not the correct calculation based on the given information. - D: $72,000 is incorrect as it is an excessively high amount and not a reasonable dividend for owning 400 shares.

Question 5 of 5

A patient is prescribed 500 mg of medication, but the available tablets are 250 mg each. How many tablets should be given?

Correct Answer: B

Rationale: The correct answer is B: 2 tablets. To reach the prescribed 500 mg dosage, two 250 mg tablets should be given. This is because 250 mg + 250 mg = 500 mg, meeting the prescription requirements accurately. Choices A, C, and D are incorrect because they do not add up to the required 500 mg dosage. Option A (3 tablets) would result in 750 mg, option C (4 tablets) would total 1000 mg, and option D (5 tablets) would equal 1250 mg, all exceeding the prescribed amount. Hence, the correct answer is 2 tablets to achieve the precise 500 mg dosage.
