Nursing Metric Conversions Questions
Question 1 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.
Question 2 of 5
How many milligrams are in 1 gram?
Correct Answer: D
Rationale: The correct answer is D: 1,000 mg. This is because there are 1,000 milligrams in 1 gram. This conversion is based on the metric system, where the prefix "milli-" represents one thousandth of the base unit. Therefore, 1 gram is equal to 1,000 milligrams. Explanation for other choices: A: 1 mg - This is incorrect as 1 mg is one-thousandth of a gram, not the other way around. B: 10 mg - This is incorrect as it is too small to be equivalent to 1 gram. C: 100 mg - This is incorrect as it is one-tenth of 1 gram, not the correct conversion.
Question 3 of 5
What is 0.5 liters equivalent to?
Correct Answer: A
Rationale: The correct answer is A: 500 ml. 0.5 liters is equal to 500 milliliters because there are 1000 milliliters in 1 liter. Therefore, to convert 0.5 liters to milliliters, you multiply 0.5 by 1000 which equals 500 ml. Choices B, C, and D are incorrect because they do not accurately convert liters to milliliters. B is too small, C and D are significantly smaller than the correct conversion.
Question 4 of 5
How many micrograms (mcg) are equivalent to 0.5 milligrams (mg)?
Correct Answer: A
Rationale: To convert milligrams (mg) to micrograms (mcg), you multiply by 1000 because 1 mg = 1000 mcg. So, to convert 0.5 mg to mcg, you multiply 0.5 by 1000, which equals 500 mcg. Therefore, the correct answer is A: 500 mcg. Choice B (50 mcg) is incorrect as it results from multiplying by 100 instead of 1000. Choice C (5 mcg) is incorrect as it results from multiplying by 10 instead of 1000. Choice D (0.5 mcg) is incorrect as it does not involve any conversion from milligrams to micrograms.
Question 5 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.
