Nursing Metric Conversion

Correct Answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter equals 1000 milliliters. So, 0.5 liters * 1000 = 500 ml. Therefore, the correct answer is A: 500 ml. Choice B (50 ml) is incorrect as it is 10 times less than the correct answer. Choice C (5 ml) is incorrect as it is 100 times less, and choice D (0.5 ml) is incorrect as it is the original volume in milliliters, not the conversion from liters.

Correct Answer: B

Rationale: To convert kilograms to grams, we need to multiply by 1000 since 1 kilogram equals 1000 grams. Therefore, 0.5 kilograms x 1000 = 500 grams. This is why choice B, 500 grams, is correct. Choice A, 50 grams, is incorrect as it is the result of multiplying by 10 instead of 1000. Choice C, 5,000 grams, is incorrect as it is the result of multiplying by 10,000 which is not the correct conversion factor. Choice D, 0.5 grams, is incorrect as it is the original amount in grams, not the converted amount from kilograms.

Correct Answer: B

Rationale: To convert from liters to milliliters, you multiply by 1000 since there are 1000 milliliters in 1 liter. So, 0.5 liters x 1000 = 500 ml. Therefore, the correct answer is B. Choice A is incorrect because 0.5 liters is not equal to 50 ml. Choice C is incorrect because 0.5 liters is not equal to 5 ml. Choice D is incorrect because 0.5 liters is not equal to 0.5 ml.

Correct Answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter equals 1000 milliliters. So, 0.5 liters * 1000 = 500 ml. Therefore, the correct answer is A: 500 ml. Choice B (50 ml) is incorrect as it is 10 times less than the correct answer. Choice C (5 ml) is incorrect as it is 100 times less, and choice D (0.5 ml) is incorrect as it is the original volume in milliliters, not the conversion from liters.

Correct Answer: C

Rationale: The correct answer is C because 1 liter is equivalent to 1.057 quarts. To convert liters to quarts, we know that 1 liter is approximately equal to 1.057 quarts. This conversion is accurate because it reflects the actual conversion factor between liters and quarts. A: 1 inch = 2.54 cm, not 2.5 cm. B: 1 meter = 39.37 inches, not an incorrect conversion but not the most accurate one. D: 1 gram = 1000 milligrams, not 100 milligrams. In summary, choices A, B, and D are incorrect due to inaccurate conversion factors, whereas choice C is correct as it provides the accurate conversion between liters and quarts.
