Metric Conversions for Nursing Questions

Question 1 of 5

Convert 0.875 to a fraction,

Correct Answer: A

Rationale: To convert 0.875 to a fraction, we first note that the decimal places indicate the denominator. Since there are three decimal places, the denominator is 10^3 = 1000. Then, 0.875 = 875/1000, which simplifies to 7/8 by dividing both the numerator and denominator by 125. Therefore, the correct answer is A (7/8). The other choices are incorrect because B (8/7) is the reciprocal of the correct answer, C (3/4) and D (9/10) do not equal 0.875.

Question 2 of 5

Convert 1.5 kilometers to meters.

Correct Answer: A

Rationale: To convert kilometers to meters, you need to multiply by 1000 since 1 kilometer is equal to 1000 meters. So, 1.5 kilometers x 1000 = 1500 meters, which is choice A. Choice B (150 meters) is incorrect as it is the result if you mistakenly multiplied by 100 instead of 1000. Choice C (15,000 meters) is incorrect as it is the result of multiplying by 10,000. Choice D (1.5 meters) is incorrect as it represents the original distance in meters, not the converted value.

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 0.004 expressed as a ratio?

Correct Answer: A

Rationale: To express 0.004 as a ratio, we need to convert it to a fraction. 0.004 = 4/1000 = 1/250. Therefore, the correct ratio is 1:250. Choice B (4:20) simplifies to 1:5, not equivalent to 1:250. Choice C (2:40) simplifies to 1:20, also incorrect. Choice D (9:20) does not represent the decimal value 0.004. Hence, the correct answer is A.

Question 5 of 5

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

Correct Answer: A

Rationale: The correct answer is A: gram. In the metric system, 'g' stands for gram, which is a unit of mass. This is the correct answer because gram is the standard unit of mass in the metric system, commonly used for measuring small weights. The other choices are incorrect because: B: grain is a unit of weight used in the imperial system, not the metric system. C: goose is not a unit of measurement in any system. D: grammage refers to the weight per unit area of paper or similar material, not a standard unit of mass in the metric system.
