Nursing Metric Conversions

Correct Answer: B

Rationale: The correct answer is B: 1,000 liters. The prefix "kilo-" represents 1,000 units. Therefore, 1 kiloliter is equal to 1,000 liters. Rationale: 1 kiloliter = 1,000 liters A: 100 liters - Incorrect, not equivalent to a kiloliter. C: 10 liters - Incorrect, too small to be a kiloliter. D: 10,000 liters - Incorrect, greater than the value of a kiloliter.

Correct Answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in 1 liter. Therefore, to find how many milliliters are in 0.5 liters, you would multiply 0.5 by 1000 which equals 500 ml. This makes choice A, 500 ml, the correct answer. Choices B, C, and D are incorrect because they do not correctly convert liters to milliliters. Choice B (50 ml) is 10 times less than the correct answer, choice C (5 ml) is 100 times less, and choice D (0.5 ml) is 1000 times less than the correct answer.

Correct Answer: B

Rationale: To convert meters to centimeters, we know that 1 meter is equal to 100 centimeters. Therefore, to find how many centimeters are in 0.25 meters, we multiply 0.25 by 100, giving us 25 centimeters. Explanation for incorrect choices: A: 2.5 cm - Incorrect because 0.25 meters is equivalent to 25 cm. C: 250 cm - Incorrect because multiplying 0.25 by 100 gives 25 cm, not 250 cm. D: 0.25 cm - Incorrect because this doesn't follow the conversion from meters to centimeters.

Correct Answer: D

Rationale: The correct answer is D: 1,000 mg. This is because there are 1,000 milligrams in 1 gram. This conversion is based on the metric system, where the prefix "milli-" represents one thousandth of the base unit. Therefore, 1 gram is equal to 1,000 milligrams. Explanation for other choices: A: 1 mg - This is incorrect as 1 mg is one-thousandth of a gram, not the other way around. B: 10 mg - This is incorrect as it is too small to be equivalent to 1 gram. C: 100 mg - This is incorrect as it is one-tenth of 1 gram, not the correct conversion.

Correct Answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter equals 1000 milliliters. So, 0.2 liters x 1000 = 200 milliliters, making choice B the correct answer. Choice A is incorrect as it represents 0.02 liters. Choice C is incorrect as it represents 0.002 liters. Choice D is incorrect as it represents 2 liters, not 0.2 liters.
