Nursing Metric Conversions

Correct Answer: B

Rationale: To convert grams to milligrams, you need to multiply by 1,000 since there are 1,000 milligrams in 1 gram. So, 2 grams x 1,000 = 2,000 mg. Therefore, the correct answer is B. A: 200 mg - This is incorrect as it doesn't account for the conversion factor from grams to milligrams. C: 20 mg - This is incorrect as it is 100 times less than the correct conversion. D: 20,000 mg - This is incorrect as it is 10 times greater than the correct conversion.

Correct Answer: A

Rationale: To convert 0.03 to a fraction, we can write it as 3/100 since 0.03 can be expressed as 3 hundredths. Therefore, the correct answer is A: 3/100. Option B (1/30) is incorrect because it represents 0.033, not 0.03. Option C (1/3) is incorrect as it represents 0.3, not 0.03. Option D (1/10) is incorrect as it represents 0.1, not 0.03.

Correct Answer: C

Rationale: To convert from quarts to ounces, you need to know that 1 quart is equal to 32 ounces. Therefore, 2 quarts would be 2 * 32 = 64 ounces. The correct answer is C (16 ounces) because it is the only option that correctly states the conversion from quarts to ounces. Option A (8 ounces) is incorrect as it is half of the correct answer. Option B (32 ounces) is incorrect as it represents the amount in 1 quart, not 2 quarts. Option D (64 ounces) is incorrect as it corresponds to the total number of ounces in 2 quarts, not the conversion from quarts to ounces.

Correct Answer: B

Rationale: To convert kilograms to grams, we must remember that 1 kilogram is equal to 1000 grams. Therefore, to find how many grams are in 2 kilograms, we multiply 2 by 1000, which equals 2000 grams. This makes choice B the correct answer. Choices A, C, and D are incorrect because they do not correctly convert kilograms to grams. Choice A is the result of mistakenly multiplying by 100 instead of 1000. Choice C is the result of dividing instead of multiplying. Choice D is simply the original amount in kilograms, without conversion.

Correct Answer: B

Rationale: The correct answer is B: grams. Grams are the base unit for mass in the metric system. The metric system is based on powers of ten, making it easy to convert between units. Milligrams (A) are smaller units, kilograms (C) are larger units, and tons (D) are even larger units. Grams are the most commonly used unit for measuring everyday items and are the standard unit for mass in the metric system.
