Nursing Metric Conversions Questions

Question 1 of 5

Convert 0.004 to a ratio.

Correct Answer: A

Rationale: To convert 0.004 to a ratio, we need to express it in the form of a fraction. 0.004 as a fraction is 4/1000, which simplifies to 1/250. Therefore, the correct ratio is 1:250. Choice A is correct as it represents the simplified form of 0.004. Choices B, C, and D are incorrect as they do not accurately represent the conversion of 0.004 to a ratio.

Question 2 of 5

How many milliliters are in 1.5 liters?

Correct Answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter = 1000 milliliters. Therefore, 1.5 liters x 1000 = 1500 milliliters. So, the correct answer is B: 1,500 mL. A is incorrect as it is 10 times less than the correct answer. C is incorrect as it is 10 times less than the correct answer. D is incorrect as it is 100 times more than the correct answer.

Question 3 of 5

Convert 0.1 liter to milliliters. What is the equivalent volume?

Correct Answer: C

Rationale: To convert 0.1 liter to milliliters, we know that 1 liter equals 1000 milliliters. Therefore, 0.1 liter is equivalent to 0.1 x 1000 = 100 milliliters. Hence, the correct answer is C: 100 ml. Explanation for other choices: A: 1 ml - Incorrect, as 0.1 liter is larger than 1 ml. B: 10 ml - Incorrect, as 0.1 liter is equivalent to 100 ml, not 10 ml. D: 1000 ml - Incorrect, as 0.1 liter is smaller than 1000 ml.

Question 4 of 5

The SI prefixes micro and milli represent, respectively:

Correct Answer: A

Rationale: The SI prefix "micro" represents 10^-6 and "milli" represents 10^-3. To understand this, recall that "micro" comes from the Greek word for small, and it signifies a factor of 1/1,000,000 (10^-6). On the other hand, "milli" indicates a factor of 1/1,000 (10^-3). Therefore, the correct answer is A: 10^-6 and 10^-3. Choice B (10^-9 and 10^-6) is incorrect because it confuses the values of micro and nano prefixes. Choice C (10^-12 and 10^-9) is incorrect as it mixes up the prefixes for pico and nano. Choice D (10^-15 and 10^-12) is incorrect as it refers to femto and pico prefixes, respectively.

Question 5 of 5

Convert 0.004 to a ratio.

Correct Answer: A

Rationale: To convert 0.004 to a ratio, we need to express it in the form of a fraction. 0.004 as a fraction is 4/1000, which simplifies to 1/250. Therefore, the correct ratio is 1:250. Choice A is correct as it represents the simplified form of 0.004. Choices B, C, and D are incorrect as they do not accurately represent the conversion of 0.004 to a ratio.
