Nursing Metric Conversion Questions

Question 1 of 5

What is 0.004 as a ratio?

Correct Answer: B

Rationale: To express 0.004 as a ratio, we can consider it as 4/1000. Simplifying this gives us 1/250. Therefore, the correct ratio is 1:250. Choice A is incorrect as it simplifies to 1:2. Choice C simplifies to 1:4. Choice D is equivalent to 4:0, which is undefined in ratio form. The correct answer, B, accurately represents 0.004 as a ratio of 1:250.

Question 2 of 5

Convert 35.40 kilograms to grams (g).

Correct Answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in 1 kilogram. Therefore, 35.40 kg x 1000 = 35,400 g (Choice B). This is the correct answer because it correctly applies the conversion factor. Choices A, C, and D are incorrect as they do not correctly convert kilograms to grams. Choice A is too small, Choice C is missing a zero, and Choice D incorrectly divides instead of multiplies.

Question 3 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 4 of 5

How many liters are in 750 milliliters?

Correct Answer: B

Rationale: To convert milliliters to liters, we divide by 1000 since there are 1000 milliliters in a liter. So, 750 milliliters ÷ 1000 = 0.75 liters. Therefore, the correct answer is B. Choice A is incorrect as it incorrectly moves the decimal point. Choices C and D are incorrect as they incorrectly add extra zeros and move the decimal point in the wrong direction.

Question 5 of 5

What is 0.2 mg converted to mcg?

Correct Answer: A

Rationale: To convert 0.2 mg to mcg, we need to remember that 1 mg is equal to 1000 mcg. So, to convert 0.2 mg to mcg, we multiply 0.2 by 1000, which gives us 200 mcg. Therefore, the correct answer is A: 200 mcg. Incorrect answers: B: 20 mcg - Incorrect because it does not account for the correct conversion factor of 1000 mcg per 1 mg. C: 2000 mcg - Incorrect as it incorrectly multiplies 0.2 mg by 1000 twice. D: 2 mcg - Incorrect as it does not consider the correct conversion of 0.2 mg to mcg.
