Nursing Metric Conversions Questions

Question 1 of 5

Convert 3,540 liters to milliliters (mL).

Correct Answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000 because there are 1000 milliliters in 1 liter. So, 3,540 liters x 1000 = 3,540,000 mL. Therefore, choice B (3,540,000 mL) is the correct answer. Choice A (354,000 mL) is incorrect because it doesn't account for the conversion factor. Choice C (35,400 mL) and choice D (35,400,000 mL) are also incorrect as they do not correctly apply the conversion factor.

Question 2 of 5

What is 0.025 mg converted to micrograms?

Correct Answer: A

Rationale: To convert mg to mcg, you multiply by 1000 since 1 mg = 1000 mcg. Therefore, 0.025 mg * 1000 = 25 mcg, which is choice A. Choice B is incorrect as it incorrectly multiplies by 10 instead of 1000. Choice C is incorrect as it incorrectly divides by 10. Choice D is incorrect as it incorrectly divides by 100 instead of multiplying by 1000.

Question 3 of 5

How many ounces are in one gallon?

Correct Answer: B

Rationale: To convert gallons to ounces, we know that 1 gallon is equal to 128 fluid ounces. Therefore, the correct answer is B. Choice A (64 ounces) is incorrect as it represents half a gallon. Choice C (100 ounces) and D (150 ounces) do not correspond to the standard conversion of gallons to ounces.

Question 4 of 5

How many millimeters are in 1 centimeter?

Correct Answer: B

Rationale: The correct answer is B: 10 mm. 1 centimeter is equal to 10 millimeters. This is because the metric system is based on units of 10. Therefore, to convert from centimeters to millimeters, you simply multiply by 10. The other choices are incorrect because: A: 1 mm - This is the equivalent of 1 millimeter, not 1 centimeter. C: 100 mm - This is the equivalent of 100 millimeters, not 1 centimeter. D: 1,000 mm - This is the equivalent of 1,000 millimeters, not 1 centimeter.

Question 5 of 5

What is the expression 1 in. = 2.54 cm properly called?

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.
