Metric Conversions for Nursing Questions

Question 1 of 5

Convert 0.345 kilometers to meters (m).

Correct Answer: B

Rationale: To convert kilometers to meters, we need to multiply by 1000 since there are 1000 meters in 1 kilometer. Therefore, 0.345 km * 1000 = 345 meters. Choice B, 345 meters, is the correct answer. Choice A (3.45 m) is incorrect as it doesn't account for the conversion factor of 1000. Choice C (345 cm) is incorrect as it converts to centimeters instead of meters. Choice D (345 m) is incorrect as it matches the correct answer but lacks the necessary conversion step.

Question 2 of 5

What is 0.4 divided by 40?

Correct Answer: B

Rationale: To divide 0.4 by 40, we can rewrite 0.4 as 4/10. Then, we divide 4 by 10 to get 0.1. So, 0.4 divided by 40 equals 0.1. Simplifying 0.1 as a fraction gives 1/10. To further simplify, we can divide both the numerator and denominator by 10 to get 1/1000, which is choice B. Choices A, C, and D are incorrect as they do not accurately represent the division of 0.4 by 40.

Question 3 of 5

How many centimeters are in 4 meters?

Correct Answer: B

Rationale: To convert meters to centimeters, you multiply by 100 (1 meter = 100 cm). So, 4 meters x 100 cm/meter = 400 cm (Choice B). Choice A (40 cm) is incorrect as it represents 0.4 meters. Choice C (4 cm) is incorrect as it corresponds to 0.04 meters. Choice D (0.4 cm) is incorrect as it is 0.004 meters. Therefore, the correct answer is B (400 cm) as it accurately represents 4 meters in centimeters.

Question 4 of 5

What is 0.04 g in mg?

Correct Answer: A

Rationale: To convert grams to milligrams, you need to multiply by 1000 since 1 g = 1000 mg. Therefore, 0.04 g * 1000 = 40 mg. Thus, the correct answer is A: 40 mg. Choice B is incorrect as it is 10 times more than the correct answer. Choice C is incorrect as it is 10 times less than the correct answer. Choice D is incorrect as it is 100 times less than the correct answer.

Question 5 of 5

How many mcg are there in 0.2 mg?

Correct Answer: B

Rationale: To convert milligrams (mg) to micrograms (mcg), you need to multiply by 1000. Therefore, to find how many mcg are in 0.2 mg, you would multiply 0.2 by 1000, which equals 200 mcg. Choice B is correct. Choices A, C, and D are incorrect as they do not accurately convert 0.2 mg to mcg. Choice A is too low, choice C is too high, and choice D is too low.
