Nursing Metric Conversions Questions
Question 1 of 5
What is 0.2 rounded to the nearest tenth?
Correct Answer: B
Rationale: The number 0.2 rounded to the nearest tenth means rounding to one decimal place. Since the digit after the tenths place is 0, we keep the tenths place as it is. Therefore, the correct answer is B: 0.2. A: 0.1 - Incorrect, this is rounding down to the nearest tenth. C: 0.3 - Incorrect, this is rounding up to the nearest tenth. D: 0.25 - Incorrect, this is rounding to the nearest hundredth, not tenth.
Question 2 of 5
What does 'm' stand for in the metric system?
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.
Question 3 of 5
Convert 0.075 mg to micrograms.
Correct Answer: D
Rationale: To convert mg to mcg, we need to multiply by 1000 since 1 mg = 1000 mcg. So, 0.075 mg x 1000 = 75 mcg. Therefore, the correct answer is D: 750 mcg. The other choices are incorrect because they do not correctly convert milligrams to micrograms. A, B, and C are not the correct conversion of 0.075 mg to mcg.
Question 4 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.
Question 5 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.
