HESI A2 Quizlet Math Questions

Question 1 of 5

If you have 4 kilograms, how many grams would you have?

Correct Answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1000 since 1 kilogram is equal to 1000 grams. So, 4 kilograms x 1000 = 4000 grams. The correct answer is B. Choice A is incorrect as it only represents 1/10th of the correct value. Choice C is way too low and represents 1/100th of the correct value. Choice D is also significantly lower than the correct value.

Question 2 of 5

How many inches are in 2 yards?

Correct Answer: D

Rationale: To convert yards to inches, we need to know that 1 yard is equal to 36 inches. So, to find out how many inches are in 2 yards, we multiply 2 by 36, which equals 72 inches. Therefore, the correct answer is D. Choice A (36 inches) is the equivalent of 1 yard, not 2 yards. Choice B (48 inches) and C (60 inches) are incorrect conversions of 2 yards to inches.

Question 3 of 5

The physician orders 1000 mg of Benadryl liquid; 1 g = 1 tsp. How many teaspoons will you give?

Correct Answer: C

Rationale: To convert 1000 mg to teaspoons, we use the given conversion factor of 1 g = 1 tsp. First, we convert mg to grams by dividing 1000 mg by 1000 (1 g = 1000 mg), which equals 1 g. Since 1 g is equivalent to 1 tsp according to the conversion factor, the correct answer is 1 tsp. Choice A (.75 tsp) is incorrect because 1 g is equivalent to 1 tsp, not .75 tsp. Choice B (1.5 tsp) is incorrect as 1000 mg equals 1 g, which corresponds to 1 tsp, not 1.5 tsp. Choice D (1.25 tsp) is incorrect because 1000 mg converts to 1 tsp, not 1.25 tsp.

Question 4 of 5

Convert 5 3/4 to a decimal. Round to the nearest tenth.

Correct Answer: C

Rationale: To convert 5 3/4 to a decimal, we first convert the mixed number to an improper fraction: 5 3/4 = (4*5 + 3)/4 = 23/4. Then, divide the numerator by the denominator to get the decimal: 23 ÷ 4 = 5.75. When rounded to the nearest tenth, 5.75 becomes 5.8. Therefore, the correct answer is C (5.8). Choices A (5.75) and B (5.7) are incorrect as they do not account for rounding to the nearest tenth. Choice D (6) is incorrect as it is the closest whole number approximation, but does not accurately represent 5 3/4 as a decimal rounded to the nearest tenth.

Question 5 of 5

How many grams are in 4 kilograms?

Correct Answer: A

Rationale: To convert kilograms to grams, you need to multiply the number of kilograms by 1000, as there are 1000 grams in 1 kilogram. Therefore, 4 kilograms x 1000 = 4000 grams, which is the correct answer (A). Choices B, C, and D are incorrect because they do not correctly convert 4 kilograms to grams.
