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
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
What is the formula for calculating the volume of a solid object?
Correct Answer: B
Rationale: The correct formula for calculating the volume of a solid object is V = L x W x H. This formula represents the length (L), width (W), and height (H) of the object multiplied together to obtain the volume. Each dimension contributes to the overall volume of the object, making this formula accurate and comprehensive. Explanation for incorrect choices: A: V = W/L - This formula represents the ratio of width to length, not the volume of a solid object. C: V = W/H - This formula represents the ratio of width to height, not the volume of a solid object. D: V = L/W - This formula represents the ratio of length to width, not the volume of a solid object.
Question 5 of 5
Convert 3,540 liters to milliliters (mL).
Correct Answer: B
Rationale: To convert liters to milliliters, you need to multiply by 1000 because there are 1000 milliliters in 1 liter. So, 3,540 liters x 1000 = 3,540,000 mL. Therefore, choice B (3,540,000 mL) is the correct answer. Choice A (354,000 mL) is incorrect because it doesn't account for the conversion factor. Choice C (35,400 mL) and choice D (35,400,000 mL) are also incorrect as they do not correctly apply the conversion factor.
