Nursing Metric Conversions

Correct Answer: C

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter is equal to 1000 milliliters. So, 3.75 liters x 1000 = 3750 milliliters. Therefore, the correct answer is C. Explanation for incorrect choices: A: 3.75 ml - This is the same value in milliliters, not a conversion. B: 375 ml - Incorrect conversion, as it should be 3750 ml. D: 37.5 ml - Incorrect conversion, it's missing a zero making it ten times less than the correct answer.

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.

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.

Correct Answer: D

Rationale: The correct answer is D: Exact Equivalent. This term refers to a precise conversion between two different units of measurement without any approximation. In this case, 1 inch is exactly equal to 2.54 centimeters, making it an exact equivalent. A: Law of Conservation of Units - This choice is incorrect because it does not refer to the specific term used for the conversion between inches and centimeters. B: International Yard - This choice is incorrect as it does not accurately describe the relationship between inches and centimeters. C: Standard Conversion Factor - This choice is incorrect because it is a general term and does not specifically address the exact relationship between inches and centimeters.

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.
