Nursing Metric Conversion Questions

Question 1 of 5

Convert 0.025 mg to micrograms.

Correct Answer: A

Rationale: To convert milligrams (mg) to micrograms (mcg), you need to multiply by 1000 since there are 1000 micrograms in 1 milligram. So, 0.025 mg x 1000 = 25 mcg, which is option A. Option B is incorrect as it incorrectly multiplies by 10. Option C is incorrect as it incorrectly divides by 10. Option D is incorrect as it incorrectly divides by 100. Always remember the conversion factor of 1000 when converting between milligrams and micrograms.

Question 2 of 5

Convert 0.025 mg to micrograms.

Correct Answer: A

Rationale: To convert milligrams (mg) to micrograms (mcg), you need to multiply by 1000 since there are 1000 micrograms in 1 milligram. So, 0.025 mg x 1000 = 25 mcg, which is option A. Option B is incorrect as it incorrectly multiplies by 10. Option C is incorrect as it incorrectly divides by 10. Option D is incorrect as it incorrectly divides by 100. Always remember the conversion factor of 1000 when converting between milligrams and micrograms.

Question 3 of 5

What does 'mg' stand for in the metric system?

Correct Answer: B

Rationale: The correct answer is B: milligram. In the metric system, 'mg' stands for milligram, which is a unit of mass equal to one thousandth of a gram. To determine the correct answer, you need to understand the metric prefixes. 'Micro' means one millionth, 'milli' means one thousandth, 'giga' means one billion, and 'mega' means one million. Therefore, A is incorrect because 'micro' is smaller than 'milli', C is incorrect because 'giga' is much larger than 'milli', and D is incorrect because 'megagram' is a unit equal to one million grams, not milligrams.

Question 4 of 5

What is 0.04 grams converted to milligrams?

Correct Answer: A

Rationale: To convert grams to milligrams, you need to multiply by 1000 since there are 1000 milligrams in a gram. So, 0.04 grams * 1000 = 40 milligrams. Therefore, the correct answer is A: 40 mg. Incorrect choices: B: 4 mg - This is incorrect because it does not account for the conversion factor of 1000. C: 400 mg - This is incorrect as it is a result of multiplying by 10 instead of 1000. D: 0.4 mg - This is incorrect as it is the result of dividing by 10 instead of multiplying by 1000.

Question 5 of 5

Convert 345,000 millimeters to centimeters (cm).

Correct Answer: B

Rationale: To convert millimeters to centimeters, we divide by 10 since there are 10 millimeters in a centimeter. So, 345,000 mm ÷ 10 = 34,500 cm. Therefore, the correct answer is B. Choice A is incorrect as it doesn't involve dividing by 10. Choice C is incorrect as it doesn't consider the conversion factor. Choice D is incorrect as it adds extra zeros, which is not necessary for this conversion.
