Metric Conversions for Nursing

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.

Correct Answer: A

Rationale: To convert liters to ounces, we need to know that 1 liter is equal to 33.814 ounces. Therefore, 0.5 liter would be 0.5 * 33.814 = 16.907 ounces. Rounding to two decimal places, the correct answer is 16.91 oz (choice A). Choices B, C, and D are incorrect as they do not accurately represent the conversion of 0.5 liter to ounces.

Correct Answer: A

Rationale: To convert grams to kilograms, divide the number of grams by 1000. In this case, 100 grams divided by 1000 equals 0.1 kilograms (A). Choice B is incorrect because it represents the equivalent of 1000 grams, not 100 grams. Choice C is incorrect as it represents 10 times the amount of 100 grams. Choice D is incorrect as it represents one-hundredth of 100 grams, not the correct conversion.

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.

Correct Answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters x 1000 = 500 ml. Choice A (500 ml) is correct. Choices B, C, and D are incorrect because they do not accurately convert liters to milliliters.
