Nursing Metric Conversions

Correct Answer: C

Rationale: To convert 0.1 liter to milliliters, we know that 1 liter equals 1000 milliliters. Therefore, 0.1 liter is equivalent to 0.1 x 1000 = 100 milliliters. Hence, the correct answer is C: 100 ml. Explanation for other choices: A: 1 ml - Incorrect, as 0.1 liter is larger than 1 ml. B: 10 ml - Incorrect, as 0.1 liter is equivalent to 100 ml, not 10 ml. D: 1000 ml - Incorrect, as 0.1 liter is smaller than 1000 ml.

Correct Answer: A

Rationale: The correct answer is A: meter. In the metric system, 'm' stands for meter, which is the base unit of length. Mole (B) is a unit of amount of substance, milli (C) represents a prefix meaning one-thousandth, and micro (D) represents a prefix meaning one-millionth. Therefore, A is the correct choice as it directly corresponds to the unit of length in the metric system.

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.

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: 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.
