Metric Conversions for Nursing Questions

Question 1 of 5

What is 0.4 divided by 40?

Correct Answer: B

Rationale: To divide 0.4 by 40, we can rewrite 0.4 as 4/10. Then, we divide 4 by 10 to get 0.1. So, 0.4 divided by 40 equals 0.1. Simplifying 0.1 as a fraction gives 1/10. To further simplify, we can divide both the numerator and denominator by 10 to get 1/1000, which is choice B. Choices A, C, and D are incorrect as they do not accurately represent the division of 0.4 by 40.

Question 2 of 5

What is 0.875 as a simplified fraction?

Correct Answer: A

Rationale: To convert 0.875 to a fraction, we note that it is 875/1000. Simplifying this gives 7/8, making A the correct answer. Choice B, 9/10, and C, 5/6, are incorrect as they do not equal 0.875 when converted to decimals. Choice D, 3/4, is also incorrect as it is not equivalent to 0.875.

Question 3 of 5

What does 'cm' stand for in the metric system?

Correct Answer: A

Rationale: The correct answer is A: centimeter. 'cm' stands for centimeter in the metric system. 'Centi' is a prefix that means one hundredth, so centimeter represents one hundredth of a meter. Choice B, cubic meter, is incorrect because 'cm' does not refer to volume. Choice C, cord, is a unit of measurement for stacked firewood and is not related to 'cm.' Choice D, centi, is a prefix used to indicate one hundredth, but it is not the complete unit itself.

Question 4 of 5

What is 0.04 g in mg?

Correct Answer: A

Rationale: To convert grams to milligrams, you need to multiply by 1000 since 1 g = 1000 mg. Therefore, 0.04 g * 1000 = 40 mg. Thus, the correct answer is A: 40 mg. Choice B is incorrect as it is 10 times more than the correct answer. Choice C is incorrect as it is 10 times less than the correct answer. Choice D is incorrect as it is 100 times less than the correct answer.

Question 5 of 5

How many ounces is equal to 1 gram?

Correct Answer: B

Rationale: To convert grams to ounces, we need to know that 1 ounce is approximately equal to 28.35 grams. Therefore, 1 gram is equal to 1/28.35 ounces, which is approximately 0.035 ounces. So, the correct answer is B. Incorrect Choices: A: 0.015 ounces - This is too low, as 1 gram is closer to 0.035 ounces. C: 0.045 ounces - This is too high, as 1 gram is closer to 0.035 ounces. D: 0.055 ounces - This is also too high, as 1 gram is closer to 0.035 ounces.
