Math HESI A2 Practice Test

Correct Answer: B

Rationale: To find total calories consumed in 3 meals, multiply 500 calories/meal by 3 meals: 500 x 3 = 1500 calories. This is why choice B is correct. Choices A, C, and D are incorrect because they do not accurately calculate the total calories consumed in 3 meals. Choice A is half the correct answer, choice C is double, and choice D is the amount of calories in one meal, not for 3 meals.

Correct Answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000. Therefore, to find how many milliliters are in 6 liters, you would multiply 6 by 1000, which equals 6000 milliliters. Choice A (60 milliliters) is incorrect as it is 100 times less than the correct answer. Choice C (600 milliliters) is incorrect as it is 10 times less than the correct answer. Choice D (0.6 milliliters) is incorrect as it is a decimal and represents a fraction of the milliliters in 6 liters.

Correct Answer: A

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in 1 kilogram. So, to find the number of grams in 10 kilograms: 10 kilograms x 1000 = 10,000 grams. Therefore, the correct answer is A: 10,000 grams. The other choices are incorrect because they do not correctly convert 10 kilograms to grams. B: 100 grams is too small, C: 1000 grams is equivalent to 1 kilogram, and D: 100,000 grams is too large.

Correct Answer: A

Rationale: To convert 5/8 to a decimal, divide 5 by 8, which equals 0.625. The correct answer is A (0.625) because it is the result of dividing the numerator by the denominator. Choice B (0.5) is incorrect as 5/8 is not equal to 0.5. Choice C (0.4) and choice D (0.75) are also incorrect as they do not represent the equivalent decimal value of 5/8.

Correct Answer: D

Rationale: To convert Celsius to Fahrenheit, you use the formula: Fahrenheit = (Celsius x 1.8) + 32. Given the patient's temperature is 38.5 degrees Celsius, Fahrenheit = (38.5 x 1.8) + 32 = 104.9 degrees Fahrenheit (Option D). Options A, B, and C are incorrect as they do not match the correct conversion using the formula.
