HESI A2

Math HESI A2 Practice Test

1. If a person consumes 500 calories per meal, how many calories will they consume in 3 meals?

A. 1000 calories
B. 1500 calories
C. 2000 calories
D. 500 calories

Correct answer: B

Rationale: To find the total calories consumed in 3 meals, you multiply the number of meals by the calories per meal: 3 meals x 500 calories/meal = 1500 calories. Therefore, the correct answer is 1500 calories. Choice A (1000 calories) is incorrect because it miscalculates the total calories. Choice C (2000 calories) is incorrect as it overestimates the total calories. Choice D (500 calories) is incorrect as it represents the calories consumed in a single meal, not in 3 meals.

2. What is the author’s attitude toward the use of cosmetics?

A. Sympathetic
B. Mocking
C. Tolerant
D. Disapproving

Correct answer: D

Rationale: The author’s tone is disapproving, as evidenced by the focus on the negative consequences of using cosmetics with harmful ingredients. The passage discusses historical and contemporary health issues related to beauty practices, indicating a critical stance on the use of cosmetics that compromise health, which supports option D.

3. Everyone thought that was the __________ test of the whole course.

A. Most easiest
B. Most easy
C. Easiest
D. Easy

Correct answer: C

Rationale: The correct answer is C: 'Easiest.' The word 'easiest' is the correct superlative form of 'easy,' which is used to compare one item against others in terms of degree. 'Most easiest' and 'most easy' are grammatically incorrect. Choice D, 'Easy,' is incorrect as it is not a superlative form and does not convey a comparison of the test against others in the course.

4. How many electron pairs are shared to form a double covalent bond?

A. 1
B. 2
C. 3
D. 4

Correct answer: B

Rationale: The correct answer is B. In a double covalent bond, two pairs of electrons are shared between two atoms. This sharing of two electron pairs results in a stronger bond compared to a single covalent bond where only one pair of electrons is shared. Choice A is incorrect because a single covalent bond involves the sharing of one pair of electrons. Choices C and D are incorrect as they do not represent the correct number of electron pairs shared in a double covalent bond.

5. How many liters are there in 2,500 milliliters?

A. 2.5 liters
B. 25 liters
C. 250 liters
D. 25,000 liters

Correct answer: A

Rationale: There are 1,000 milliliters in a liter. To convert 2,500 milliliters to liters, you divide by 1,000: 2,500 milliliters / 1,000 = 2.5 liters. Therefore, choice A, '2.5 liters,' is the correct answer. Choice B, '25 liters,' is incorrect as it would be the result if you mistakenly multiplied instead of dividing. Choice C, '250 liters,' is incorrect as it is 100 times the correct answer. Choice D, '25,000 liters,' is significantly higher and not a conversion error but an order of magnitude error.
