Metric Conversions for Nursing Questions
Question 1 of 5
What is 0.2 liters when converted to milliliters?
Correct Answer: B
Rationale: The correct answer is B: 200 ml. To convert liters to milliliters, you need to multiply by 1000 since 1 liter equals 1000 milliliters. Therefore, 0.2 liters x 1000 = 200 ml. A) 20 ml is incorrect as it is the result of incorrectly converting 0.02 liters. C) 2 ml is incorrect as it is the result of incorrectly converting 0.002 liters. D) 2000 ml is incorrect as it is the result of incorrectly converting 2 liters.
Question 2 of 5
What is 0.5 liters in ml?
Correct Answer: A
Rationale: To convert liters to milliliters, you multiply by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters is equal to 0.5 x 1000 = 500 ml. Choice A (500 ml) is correct. Choices B, C, and D are incorrect because they do not follow the correct conversion factor of 1 liter to 1000 milliliters. B (50 ml), C (5 ml), and D (0.5 ml) are not the correct conversions for 0.5 liters.
Question 3 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 4 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 5 of 5
How many centimeters are in 4 meters?
Correct Answer: B
Rationale: To convert meters to centimeters, you multiply by 100 (1 meter = 100 cm). So, 4 meters x 100 cm/meter = 400 cm (Choice B). Choice A (40 cm) is incorrect as it represents 0.4 meters. Choice C (4 cm) is incorrect as it corresponds to 0.04 meters. Choice D (0.4 cm) is incorrect as it is 0.004 meters. Therefore, the correct answer is B (400 cm) as it accurately represents 4 meters in centimeters.
