Metric Conversions for Nursing Questions

Question 1 of 5

What is 0.125 as a fraction?

Correct Answer: A

Rationale: To convert 0.125 to a fraction, we observe that the decimal has 3 decimal places, so the denominator should be 1000. Thus, 0.125 as a fraction is 125/1000, which simplifies to 1/8 by dividing both numerator and denominator by 125. Therefore, the correct answer is A: 1/8. Option B: 1/4 is incorrect because 0.125 is smaller than 0.25. Option C: 1/2 is incorrect as 0.125 is smaller than 0.5. Option D: 1/16 is incorrect as it is too small to represent 0.125.

Question 2 of 5

Convert 0.07 to a fraction.

Correct Answer: A

Rationale: To convert 0.07 to a fraction, we note that 0.07 = 7/100. The rationale is to move the decimal two places to the right to get the numerator and place it over 100 (10^2) to get the denominator. Option A (7/100) is correct. Option B (1/10) is incorrect because it represents 0.1, not 0.07. Option C (1/20) is incorrect as it represents 0.05. Option D (1/50) is incorrect as it represents 0.02.

Question 3 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 4 of 5

What is 0.5 x 200?

Correct Answer: A

Rationale: To solve 0.5 x 200, we multiply 0.5 by 200, which equals 100. This is because when we multiply a decimal by a whole number, we move the decimal point to the right the same number of places as the total number of decimal places in the factors. In this case, 0.5 has one decimal place, and 200 is a whole number. Therefore, the correct answer is A: 100. Choice B: 50 is incorrect because it results from multiplying 0.5 by 100 instead of 200. Choice C: 150 is incorrect as it is the result of multiplying 0.5 by 300. Choice D: 200 is incorrect because it is one of the factors in the multiplication operation, not the result of the operation.

Question 5 of 5

How many milliliters are in 2 liters?

Correct Answer: C

Rationale: The correct answer is C: 2,000 mL. To convert liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in 1 liter. So, 2 liters x 1,000 mL = 2,000 mL. Explanation for Other Choices: A: 20 mL - This is incorrect as it is just 1% of 2 liters. B: 200 mL - This is also incorrect as it is 10% of 2 liters. D: 20,000 mL - This is incorrect as it is 10 times the correct answer, which is too large for 2 liters.
