Metric Conversions for Nursing

Correct Answer: C

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in 1 kilogram. So, 1.25 kg x 1000 = 1250 grams, which is choice C. Choice A (12.5 grams) is incorrect as it is 10 times less than the correct answer. Choice B (125 grams) is incorrect as it is missing a zero. Choice D (1250 mg) is incorrect as it is in milligrams, not grams.

Correct Answer: A

Rationale: The conversion factor from milliliters to liters is 0.001 liters. This is because there are 1000 milliliters in 1 liter. To convert milliliters to liters, you need to divide the number of milliliters by 1000. Therefore, 1 milliliter is equal to 0.001 liters. Summary: Choice A (0.001 liters) is correct because it accurately reflects the conversion factor. Choices B, C, and D are incorrect as they do not align with the correct conversion ratio of 1 liter being equivalent to 1000 milliliters.

Correct Answer: A

Rationale: To convert 0.125 to a fraction, we observe that the decimal has 3 decimal places, so the denominator should be 1000. Thus, 0.125 as a fraction is 125/1000, which simplifies to 1/8 by dividing both numerator and denominator by 125. Therefore, the correct answer is A: 1/8. Option B: 1/4 is incorrect because 0.125 is smaller than 0.25. Option C: 1/2 is incorrect as 0.125 is smaller than 0.5. Option D: 1/16 is incorrect as it is too small to represent 0.125.

Correct Answer: A

Rationale: To convert 0.875 to a fraction, we note that it is 875/1000. Simplifying this gives 7/8, making A the correct answer. Choice B, 9/10, and C, 5/6, are incorrect as they do not equal 0.875 when converted to decimals. Choice D, 3/4, is also incorrect as it is not equivalent to 0.875.

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.
