Nursing Metric Conversions Questions
Question 1 of 5
What is 0.5 liters equivalent to?
Correct Answer: A
Rationale: The correct answer is A: 500 ml. 0.5 liters is equal to 500 milliliters because there are 1000 milliliters in 1 liter. Therefore, to convert 0.5 liters to milliliters, you multiply 0.5 by 1000 which equals 500 ml. Choices B, C, and D are incorrect because they do not accurately convert liters to milliliters. B is too small, C and D are significantly smaller than the correct conversion.
Question 2 of 5
How many pounds are in 1 ton?
Correct Answer: B
Rationale: The correct answer is B: 2000 pounds. There are 2000 pounds in 1 ton because a ton is equal to 2000 pounds. This conversion is based on the fact that 1 ton is equivalent to 2000 pounds in the imperial system of measurement. Therefore, to convert tons to pounds, you simply multiply the number of tons by 2000. Choice A (1000 pounds) is incorrect because it represents half a ton, not a full ton. Choice C (1500 pounds) and Choice D (2500 pounds) are also incorrect as they do not match the actual conversion factor of 2000 pounds in 1 ton.
Question 3 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 4 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 5 of 5
What is the formula to convert Celsius to Fahrenheit?
Correct Answer: A
Rationale: The correct formula to convert Celsius to Fahrenheit is A: (C * 9/5) + 32. To convert Celsius to Fahrenheit, you first multiply the Celsius temperature by 9/5 to get the equivalent in Fahrenheit scale, then add 32 to adjust for the offset between the two scales. This formula correctly accounts for both the scaling factor and the offset. Choices B, C, and D have incorrect scaling factors or offsets, leading to inaccurate conversions. B uses the incorrect scaling factor, C and D incorrectly subtract 32 instead of adding it.
