Nursing Metric Conversion Questions
Question 1 of 5
What is the equivalent of 255.0 pounds in kilograms (1 kg = 2.205 lbs)?
Correct Answer: D
Rationale: To convert pounds to kilograms, divide the weight in pounds by the conversion factor (2.205 lbs/kg). So, 255 lbs ÷ 2.205 lbs/kg = 115.60 kg, which is closest to choice D (115.6 kg). This choice is correct as it accurately converts 255 pounds to kilograms. The other choices are incorrect because they do not provide the correct conversion based on the given conversion factor.
Question 2 of 5
What does 'mm' stand for in the metric system?
Correct Answer: A
Rationale: The correct answer is A: millimeter. In the metric system, 'mm' stands for millimeter, which is a unit of length equal to one thousandth of a meter. This is the correct answer because "milli-" is a prefix in the metric system that denotes one thousandth. Megabyte (B) is a unit of digital information storage, not length. Millipede (C) refers to a type of arthropod, not a unit of measurement. Metered (D) is not a recognized unit in the metric system for length.
Question 3 of 5
What is 0.6 liters converted to milliliters?
Correct Answer: A
Rationale: To convert liters to milliliters, we know that 1 liter is equal to 1000 milliliters. Therefore, 0.6 liters would be equal to 0.6 x 1000 = 600 milliliters. This makes choice A (600 ml) the correct answer. Choices B, C, and D are incorrect because they do not follow the correct conversion factor of 1 liter to 1000 milliliters. Choice B (60 ml) is ten times less than the correct answer, choice C (6 ml) is one hundred times less, and choice D (0.6 ml) is one thousand times less than the correct conversion.
Question 4 of 5
Which metric prefix represents 10^-2?
Correct Answer: A
Rationale: The correct answer is A: centi. The metric prefix "centi" represents 10^-2, which means one hundredth. This is because "centi" comes from the Latin word for hundred. Therefore, when using this prefix, the base unit is divided by 100. The other choices are incorrect because: B: milli represents 10^-3, which is one thousandth. C: nano represents 10^-9, which is one billionth. D: deci represents 10^-1, which is one-tenth.
Question 5 of 5
What is 0.5 liters in milliliters?
Correct Answer: B
Rationale: To convert from liters to milliliters, you multiply by 1000 since there are 1000 milliliters in 1 liter. So, 0.5 liters x 1000 = 500 ml. Therefore, the correct answer is B. Choice A is incorrect because 0.5 liters is not equal to 50 ml. Choice C is incorrect because 0.5 liters is not equal to 5 ml. Choice D is incorrect because 0.5 liters is not equal to 0.5 ml.
