Nursing Metric Conversion Questions

Question 1 of 5

Convert 0.5 liters to milliliters.

Correct Answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in 1 liter. Therefore, 0.5 liters x 1000 = 500 milliliters, which is choice B. Choices A, C, and D are incorrect because they do not follow the correct conversion factor from liters to milliliters.

Question 2 of 5

What is 0.04 liters converted to milliliters?

Correct Answer: A

Rationale: To convert liters to milliliters, we know that 1 liter is equal to 1000 milliliters. Therefore, to convert 0.04 liters to milliliters, we multiply 0.04 by 1000, which equals 40 milliliters. This makes choice A the correct answer. Choices B, C, and D are incorrect because they do not correctly convert 0.04 liters to milliliters using the conversion factor of 1 liter = 1000 milliliters.

Question 3 of 5

What is 0.02 as a ratio?

Correct Answer: C

Rationale: To express 0.02 as a ratio, we need to convert it to a fraction: 0.02 = 2/100. Simplifying this fraction gives us 2:100, which is the same as 2/100 or 1/50. Therefore, the correct ratio for 0.02 is 2:100 (C). The other choices are incorrect because: A: 1:50 - Incorrect, as 0.02 is equivalent to 2:100, not 1:50. B: 1:20 - Incorrect, as 0.02 is equivalent to 2:100, not 1:20. D: 4:20 - Incorrect, as 0.02 simplifies to 2:100, not 4:20.

Question 4 of 5

Convert 25 millimeters to centimeters.

Correct Answer: D

Rationale: To convert millimeters to centimeters, we divide by 10 since there are 10 millimeters in 1 centimeter. Therefore, 25 mm / 10 = 2.5 cm. The correct answer is D: 25 mm, as it represents the initial quantity to be converted. Choices A and B are incorrect as they do not follow the conversion factor. Choice C is incorrect as it represents the original unit rather than the converted unit.

Question 5 of 5

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

Correct Answer: B

Rationale: The correct answer is B: milligram. In the metric system, 'mg' stands for milligram, which is a unit of mass equal to one thousandth of a gram. To determine the correct answer, you need to understand the metric prefixes. 'Micro' means one millionth, 'milli' means one thousandth, 'giga' means one billion, and 'mega' means one million. Therefore, A is incorrect because 'micro' is smaller than 'milli', C is incorrect because 'giga' is much larger than 'milli', and D is incorrect because 'megagram' is a unit equal to one million grams, not milligrams.
