Metric Conversions for Nursing

1. Convert 0.875 to a fraction,

Correct answer: A

Rationale: To convert 0.875 to a fraction, express it as 875\10000. Simplifying this fraction by dividing both the numerator and denominator by 125 results in 7\80.

2. Convert 100 grams to kilograms.

Correct answer: A

Rationale: To convert grams to kilograms, you need to divide by 1000 since there are 1000 grams in a kilogram. So, 100 grams divided by 1000 equals 0.1 kilograms, making choice A the correct answer. Choices B, C, and D are incorrect because they do not involve the correct conversion factor or calculation. Choice B of 1 kg is the equivalent of 1000 grams, which is 10 times the given value of 100 grams, making it too large. Choice C of 10 kg is 100 times the given value, and choice D of 0.01 kg is 10 times smaller than the correct conversion.

3. Convert 345 kilometers to meters (m).

Correct answer: B

Rationale: To convert kilometers to meters, you need to multiply by 1,000 since there are 1,000 meters in a kilometer. Therefore, 345 km multiplied by 1,000 equals 345,000 meters. Choice A is incorrect as it incorrectly places the comma. Choice C is incorrect as it adds an extra zero at the end. Choice D is incorrect as it adds an extra zero at the beginning, resulting in an incorrect conversion.

4. The metric prefix of Tera is abbreviated as T- and has a value of 10^12. What does Tera mean numerically?

Correct answer: C

Rationale: The correct answer is C: 10^12. Tera represents a numerical value of 10^12, which is equivalent to one trillion. It is commonly used in computing and other fields to denote large-scale measurements. Choice A, 10^6, is incorrect as it corresponds to the metric prefix 'Mega.' Choice B, 10^9, is incorrect and corresponds to the metric prefix 'Giga.' Choice D, 10^3, is incorrect and corresponds to the metric prefix 'Kilo.' Therefore, the correct interpretation of the metric prefix Tera is 10^12.

5. How many micrograms are in 1 milligram?

Correct answer: D

Rationale: The correct answer is D: 1,000 µg. To convert milligrams to micrograms, you need to multiply by 1,000 because there are 1,000 micrograms in 1 milligram. Choices A, B, and C are incorrect because they do not correctly convert milligrams to micrograms. 1 milligram is equal to 1,000 micrograms, making choice D the right answer.
