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 0.004 expressed as a ratio?
Correct Answer: A
Rationale: To express 0.004 as a ratio, we need to convert it to a fraction. 0.004 = 4/1000 = 1/250. Therefore, the correct ratio is 1:250. Choice B (4:20) simplifies to 1:5, not equivalent to 1:250. Choice C (2:40) simplifies to 1:20, also incorrect. Choice D (9:20) does not represent the decimal value 0.004. Hence, the correct answer is A.
Question 3 of 5
Convert 0.345 kilometers to meters (m).
Correct Answer: B
Rationale: To convert kilometers to meters, we need to multiply by 1000 since there are 1000 meters in 1 kilometer. Therefore, 0.345 km * 1000 = 345 meters. Choice B, 345 meters, is the correct answer. Choice A (3.45 m) is incorrect as it doesn't account for the conversion factor of 1000. Choice C (345 cm) is incorrect as it converts to centimeters instead of meters. Choice D (345 m) is incorrect as it matches the correct answer but lacks the necessary conversion step.
Question 4 of 5
What is the conversion factor from milliliters to liters?
Correct Answer: A
Rationale: The conversion factor from milliliters to liters is 0.001 liters. This is because there are 1000 milliliters in 1 liter. To convert milliliters to liters, you need to divide the number of milliliters by 1000. Therefore, 1 milliliter is equal to 0.001 liters. Summary: Choice A (0.001 liters) is correct because it accurately reflects the conversion factor. Choices B, C, and D are incorrect as they do not align with the correct conversion ratio of 1 liter being equivalent to 1000 milliliters.
Question 5 of 5
What is the equivalent of 3.54 millimeters in meters (m)?
Correct Answer: B
Rationale: To convert millimeters to meters, we divide by 1000 since there are 1000 millimeters in a meter. Therefore, 3.54 mm in meters is 3.54/1000 = 0.00354 meters. Choice B is correct as it correctly converts 3.54 mm to meters. Choices A, C, and D are incorrect because they do not apply the correct conversion factor. Choice A incorrectly moves the decimal point two places to the left instead of three. Choice C incorrectly multiplies by 10 instead of dividing by 1000. Choice D incorrectly moves the decimal point one place to the left instead of three.
