Nursing Metric Conversion Questions
Question 1 of 5
What is 0.04 liters converted to milliliters?
Correct Answer: A
Rationale: To convert liters to milliliters, we know that 1 liter is equal to 1000 milliliters. Therefore, to convert 0.04 liters to milliliters, we multiply 0.04 by 1000, which equals 40 milliliters. This makes choice A the correct answer. Choices B, C, and D are incorrect because they do not correctly convert 0.04 liters to milliliters using the conversion factor of 1 liter = 1000 milliliters.
Question 2 of 5
In the metric system, what factor does the prefix kilo- represent?
Correct Answer: A
Rationale: The prefix kilo- in the metric system represents the factor of 10^3. Kilo- means one thousand, so when used in conjunction with a base unit, it signifies that the value is being multiplied by 1000. For example, 1 kilometer is equal to 1000 meters. Therefore, the correct answer is A: 10^3. Choice B (10^2) is incorrect because this factor corresponds to the prefix hecto-, not kilo-. Choice C (10^4) is incorrect as it does not align with the meaning of kilo-, which specifically denotes a factor of 10^3. Choice D (10^6) is incorrect as it represents the prefix mega-, which signifies a factor of 10^6.
Question 3 of 5
What is 0.05 mcg in mg?
Correct Answer: A
Rationale: To convert micrograms (mcg) to milligrams (mg), we need to remember that 1 mcg is equal to 0.001 mg. Therefore, to convert 0.05 mcg to mg, we multiply 0.05 by 0.001 which gives us 0.00005 mg. This makes choice A the correct answer. Choices B, C, and D are incorrect because they do not correctly convert micrograms to milligrams based on the conversion factor of 0.001 mg per mcg.
Question 4 of 5
Convert 35.40 kilograms to grams (g).
Correct Answer: B
Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in 1 kilogram. Therefore, 35.40 kg x 1000 = 35,400 g (Choice B). This is the correct answer because it correctly applies the conversion factor. Choices A, C, and D are incorrect as they do not correctly convert kilograms to grams. Choice A is too small, Choice C is missing a zero, and Choice D incorrectly divides instead of multiplies.
Question 5 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.
