Nursing Metric Conversions

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: A

Rationale: Certainly! The correct answer is A: 1760 yards in one mile. This is because there are 1760 yards in a mile, as defined by the international yard agreement. This conversion is widely accepted and used in various fields. Choices B, C, and D are incorrect as they do not align with the standard conversion of yards to a mile. B, C, and D do not accurately reflect the established measurement and would lead to incorrect calculations in real-world scenarios.

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: To convert gallons to ounces, we know that 1 gallon is equal to 128 fluid ounces. Therefore, the correct answer is B. Choice A (64 ounces) is incorrect as it represents half a gallon. Choice C (100 ounces) and D (150 ounces) do not correspond to the standard conversion of gallons to ounces.

Correct Answer: A

Rationale: To convert milligrams (mg) to micrograms (mcg), you multiply by 1000 because 1 mg = 1000 mcg. So, to convert 0.5 mg to mcg, you multiply 0.5 by 1000, which equals 500 mcg. Therefore, the correct answer is A: 500 mcg. Choice B (50 mcg) is incorrect as it results from multiplying by 100 instead of 1000. Choice C (5 mcg) is incorrect as it results from multiplying by 10 instead of 1000. Choice D (0.5 mcg) is incorrect as it does not involve any conversion from milligrams to micrograms.
