Nursing Metric Conversions Questions

Question 1 of 5

How many liters are in 2,000 milliliters?

Correct Answer: B

Rationale: To convert milliliters to liters, divide by 1000 since 1 liter = 1000 milliliters. So, 2000 milliliters ÷ 1000 = 2 liters. Choice B is correct. Choice A is incorrect as it's 0.2 liters (misplaced decimal). Choice C is incorrect as it's 0.02 liters (decimal off by a factor of 10). Choice D is incorrect as it's 20 liters (decimal misplaced).

Question 2 of 5

What is the equivalent of 0.3 milliliters?

Correct Answer: B

Rationale: The correct answer is B: 0.3 ml. To convert milliliters to milliliters, we don't need to change the value. Therefore, the equivalent of 0.3 milliliters is still 0.3 ml. A: 0.03 ml - This is incorrect as it represents a value that is one-tenth of the original amount. C: 3 ml - This is incorrect as it represents a value that is 10 times greater than the original amount. D: 30 ml - This is incorrect as it represents a value that is 100 times greater than the original amount.

Question 3 of 5

What is 0.26 as a fraction in simplest form?

Correct Answer: A

Rationale: To convert 0.26 to a fraction, we can write it as 26/100 since 0.26 is equivalent to 26 hundredths. To simplify this fraction, we divide the numerator and denominator by their greatest common divisor, which is 2. Therefore, 26/100 simplifies to 13/50. This is the correct answer (A) in simplest form. Choice B (26/100) is the initial form of 0.26 but not in simplest form as it can be further simplified to 13/50. Choice C (26/1000) is incorrect as the decimal 0.26 is equivalent to 26/100, not 26/1000. Choice D (1/4) is not equivalent to 0.26.

Question 4 of 5

What is 0.45 liters in milliliters?

Correct Answer: A

Rationale: To convert liters to milliliters, we multiply the value by 1000 because 1 liter equals 1000 milliliters. Therefore, 0.45 liters is equal to 0.45 x 1000 = 450 milliliters. Choice A (450 ml) is correct. Choices B, C, and D are incorrect because they do not follow the correct conversion factor from liters to milliliters.

Question 5 of 5

What is 0.4 expressed in inches?

Correct Answer: C

Rationale: The correct answer is C (0.4 inches). To convert from decimals to inches, we know that 1 inch is equal to 1/100 of a foot. So, to convert 0.4 to inches, we multiply 0.4 by 12 (to convert feet to inches), which results in 4.8 inches. Therefore, 0.4 is equal to 4.8 inches. Choice A (0.04 inches) is incorrect because it is one decimal place too low. Choice B (4 inches) is incorrect because it is one decimal place too high. Choice D (40 inches) is incorrect because it is two decimal places too high.
