Nursing Metric Conversion

Correct Answer: B

Rationale: To convert millimeters to meters, you divide by 1000 since there are 1000 millimeters in a meter. So, 354,000 mm ÷ 1000 = 354 m. Choice B is correct as it correctly converts millimeters to meters. Choice A is incorrect as it doesn't account for the conversion. Choice C is incorrect as it converts to kilometers instead of meters. Choice D is incorrect as it is a miscalculation of the conversion.

Correct Answer: D

Rationale: To convert pounds to kilograms, divide the weight in pounds by the conversion factor (2.205 lbs/kg). So, 255 lbs ÷ 2.205 lbs/kg = 115.60 kg, which is closest to choice D (115.6 kg). This choice is correct as it accurately converts 255 pounds to kilograms. The other choices are incorrect because they do not provide the correct conversion based on the given conversion factor.

Correct Answer: B

Rationale: To convert milliliters to liters, we divide by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 3450 milliliters / 1000 = 3.45 liters. Choice B is correct. Choice A is incorrect as it is off by a factor of 10. Choice C is incorrect as it is off by a factor of 100. Choice D is incorrect as it is off by a factor of 1000.

Correct Answer: A

Rationale: To convert liters to milliliters, we know that 1 liter is equal to 1000 milliliters. Therefore, 0.6 liters would be equal to 0.6 x 1000 = 600 milliliters. This makes choice A (600 ml) the correct answer. Choices B, C, and D are incorrect because they do not follow the correct conversion factor of 1 liter to 1000 milliliters. Choice B (60 ml) is ten times less than the correct answer, choice C (6 ml) is one hundred times less, and choice D (0.6 ml) is one thousand times less than the correct conversion.

Correct Answer: B

Rationale: To convert 0.2 liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in 1 liter. So, 0.2 liters x 1000 = 200 milliliters, which is equivalent to 200 ml. Therefore, the correct answer is B. Other choices are incorrect because they do not follow the correct conversion factor. A is 10 times less, C is 100 times less, and D is 10 times more than the correct answer.
