Metric Conversions for Nursing Questions

Question 1 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.

Question 2 of 5

How many quarts are equivalent to 2 liters?

Correct Answer: A

Rationale: The correct answer is A: 1.06 quarts. To convert liters to quarts, we use the conversion factor 1 liter = 1.05668821 quarts. Therefore, 2 liters would be approximately 2.11337642 quarts, which can be rounded to 1.06 quarts. The other choices are incorrect because B (0.5 quarts), C (2.1 quarts), and D (4 quarts) do not accurately represent the conversion of 2 liters to quarts based on the conversion factor.

Question 3 of 5

What is 0.1 kg in grams?

Correct Answer: A

Rationale: The correct answer is A: 100 g. To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in a kilogram. Therefore, 0.1 kg x 1000 = 100 g. Choice B (10 g) is incorrect as it represents 0.01 kg. Choice C (1 g) is incorrect as it represents 0.001 kg. Choice D (0.1 g) is incorrect as it is the same value as the original measurement in kilograms.

Question 4 of 5

What is 0.5 x 200?

Correct Answer: A

Rationale: To solve 0.5 x 200, we multiply 0.5 by 200, which equals 100. This is because when we multiply a decimal by a whole number, we move the decimal point to the right the same number of places as the total number of decimal places in the factors. In this case, 0.5 has one decimal place, and 200 is a whole number. Therefore, the correct answer is A: 100. Choice B: 50 is incorrect because it results from multiplying 0.5 by 100 instead of 200. Choice C: 150 is incorrect as it is the result of multiplying 0.5 by 300. Choice D: 200 is incorrect because it is one of the factors in the multiplication operation, not the result of the operation.

Question 5 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.
