Metric Conversions for Nursing Questions
Question 1 of 5
What is 0.125 as a fraction?
Correct Answer: A
Rationale: To convert 0.125 to a fraction, we observe that the decimal has 3 decimal places, so the denominator should be 1000. Thus, 0.125 as a fraction is 125/1000, which simplifies to 1/8 by dividing both numerator and denominator by 125. Therefore, the correct answer is A: 1/8. Option B: 1/4 is incorrect because 0.125 is smaller than 0.25. Option C: 1/2 is incorrect as 0.125 is smaller than 0.5. Option D: 1/16 is incorrect as it is too small to represent 0.125.
Question 2 of 5
What is the value of one femtometer (fm) in meters?
Correct Answer: A
Rationale: The correct answer is A: 10^-15 meters. 1 femtometer is equal to 10^-15 meters. This is because the prefix "femto-" represents 10^-15. Therefore, one femtometer is equivalent to 10^-15 meters. Choice B: 10^-9 meters is incorrect as this corresponds to the prefix "nano-" not "femto-". Choice C: 10^-12 meters is incorrect as this corresponds to the prefix "pico-" not "femto-". Choice D: 10^-18 meters is incorrect as this corresponds to the prefix "atto-" not "femto-". In summary, the correct answer is A because 1 femtometer is equal to 10^-15 meters, as per the corresponding SI prefix.
Question 3 of 5
What is the equivalent of 500 milliliters in liters?
Correct Answer: B
Rationale: To convert milliliters to liters, we need to divide by 1000 since 1 liter is equal to 1000 milliliters. So, 500 milliliters divided by 1000 equals 0.5 liters, making choice B the correct answer. Choice A (0.05 liters) is incorrect as it is one decimal place off. Choice C (5 liters) and choice D (50 liters) are both significantly higher values and do not align with the conversion factor from milliliters to liters.
Question 4 of 5
How many milligrams (mg) are equal to 1 gram?
Correct Answer: B
Rationale: The correct answer is B: 1,000 mg. There are 1,000 milligrams in 1 gram. This is because the prefix "milli-" represents one thousandth, so 1 gram is equal to 1,000 milligrams. Choice A (100 mg) is incorrect because it represents only a hundredth of a gram. Choice C (1 mg) is incorrect as it is only one thousandth of a gram. Choice D (10,000 mg) is incorrect as it is actually 10 grams, not 1 gram.
Question 5 of 5
Convert 100 grams to kilograms.
Correct Answer: A
Rationale: To convert grams to kilograms, divide the number of grams by 1000. In this case, 100 grams divided by 1000 equals 0.1 kilograms (A). Choice B is incorrect because it represents the equivalent of 1000 grams, not 100 grams. Choice C is incorrect as it represents 10 times the amount of 100 grams. Choice D is incorrect as it represents one-hundredth of 100 grams, not the correct conversion.
