Nursing Metric Conversions Questions
Question 1 of 5
Convert 0.2 liters to milliliters.
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.
Question 2 of 5
Convert 3.75 liters to milliliters.
Correct Answer: C
Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter is equal to 1000 milliliters. So, 3.75 liters x 1000 = 3750 milliliters. Therefore, the correct answer is C. Explanation for incorrect choices: A: 3.75 ml - This is the same value in milliliters, not a conversion. B: 375 ml - Incorrect conversion, as it should be 3750 ml. D: 37.5 ml - Incorrect conversion, it's missing a zero making it ten times less than the correct answer.
Question 3 of 5
What is the expression 1 in. = 2.54 cm properly called?
Correct Answer: D
Rationale: The correct answer is D: Exact Equivalent. This term refers to a precise conversion between two different units of measurement without any approximation. In this case, 1 inch is exactly equal to 2.54 centimeters, making it an exact equivalent. A: Law of Conservation of Units - This choice is incorrect because it does not refer to the specific term used for the conversion between inches and centimeters. B: International Yard - This choice is incorrect as it does not accurately describe the relationship between inches and centimeters. C: Standard Conversion Factor - This choice is incorrect because it is a general term and does not specifically address the exact relationship between inches and centimeters.
Question 4 of 5
How many millimeters are in 1 centimeter?
Correct Answer: B
Rationale: The correct answer is B: 10 mm. 1 centimeter is equal to 10 millimeters. This is because the metric system is based on units of 10. Therefore, to convert from centimeters to millimeters, you simply multiply by 10. The other choices are incorrect because: A: 1 mm - This is the equivalent of 1 millimeter, not 1 centimeter. C: 100 mm - This is the equivalent of 100 millimeters, not 1 centimeter. D: 1,000 mm - This is the equivalent of 1,000 millimeters, not 1 centimeter.
Question 5 of 5
What is the equivalent of 35.4 centimeters in kilometers (km)?
Correct Answer: B
Rationale: To convert 35.4 centimeters to kilometers, we need to divide by 100, as there are 100 centimeters in a meter and 1000 meters in a kilometer. Therefore, 35.4 cm ÷ 100 = 0.354 meters. To convert meters to kilometers, we divide by 1000, so 0.354 m ÷ 1000 = 0.000354 km, which is choice B. Choices A, C, and D are incorrect as they do not follow the correct conversion factor.
