Nursing Metric Conversions Questions
Question 1 of 5
How many liters (L) are equal to 1 kiloliter?
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.
Question 2 of 5
What is 0.5 liters expressed in milliliters?
Correct Answer: B
Rationale: The correct answer is B: 500 ml. To convert liters to milliliters, you need to remember that 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters is equal to 0.5 * 1000 = 500 milliliters. Option A (50 ml) is incorrect as it represents 0.05 liters, Option C (5 ml) is incorrect as it represents 0.005 liters, and Option D (0.5 ml) is incorrect as it represents 0.0005 liters.
Question 3 of 5
How many grams are in 2 kilograms?
Correct Answer: B
Rationale: To convert kilograms to grams, we must remember that 1 kilogram is equal to 1000 grams. Therefore, to find how many grams are in 2 kilograms, we multiply 2 by 1000, which equals 2000 grams. This makes choice B the correct answer. Choices A, C, and D are incorrect because they do not correctly convert kilograms to grams. Choice A is the result of mistakenly multiplying by 100 instead of 1000. Choice C is the result of dividing instead of multiplying. Choice D is simply the original amount in kilograms, without conversion.
Question 4 of 5
How many milligrams are in 1 gram?
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.
Question 5 of 5
How many milliliters are in 0.5 liters?
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.
