Nursing Metric Conversion

Correct Answer: B

Rationale: To convert grams to kilograms, divide by 1000 since there are 1000 grams in a kilogram. So, 1500 grams / 1000 = 1.5 kg. Therefore, the correct answer is B: 1.5 kg. Incorrect choices: A: 0.15 kg - Incorrect as it is 10 times smaller than the correct answer. C: 15 kg - Incorrect as it is 10 times greater than the correct answer. D: 150 kg - Incorrect as it is 100 times greater than the correct answer.

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: A

Rationale: To convert Celsius to Kelvin, add 273.15. So, for 25°C, add 273.15 to get 298.15 K (Choice A). Choice B (273.15 K) is the freezing point of water in Kelvin, not the correct conversion for 25°C. Choices C (250 K) and D (25 K) are incorrect as they do not follow the correct conversion formula.

Correct Answer: A

Rationale: The correct answer is A: 2.54 cm. To convert inches to centimeters, we use the conversion factor 1 inch = 2.54 cm. This conversion factor is derived from the definition of an inch in the metric system. Therefore, there are 2.54 centimeters in 1 inch. Option B (3 cm) is incorrect because it does not align with the correct conversion factor of 1 inch = 2.54 cm. Option C (2 cm) is also incorrect as it does not match the accurate conversion. Option D (1 cm) is incorrect because it is not the correct conversion factor for inches to centimeters.

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.
