Nursing Metric Conversions Questions
Question 1 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.
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
Convert 0.5 centimeters to millimeters.
Correct Answer: A
Rationale: To convert centimeters to millimeters, you multiply by 10 since 1 cm = 10 mm. Therefore, 0.5 cm * 10 mm/cm = 5 mm. Choice A (5 mm) is correct. Choice B (0.5 mm) is incorrect as it represents the original value in millimeters. Choice C (50 mm) is incorrect as it is 10 times greater than the correct value. Choice D (0.05 mm) is incorrect as it is 100 times smaller than the correct value.
Question 4 of 5
Convert 0.1 liter to milliliters. What is the equivalent volume?
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.
Question 5 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.
