Nursing Metric Conversions Questions

Question 1 of 5

How many milligrams are in 1 gram?

Correct Answer: D

Rationale: The correct answer is D: 1,000 mg. This is because there are 1,000 milligrams in 1 gram. This conversion is based on the metric system, where the prefix "milli-" represents one thousandth of the base unit. Therefore, 1 gram is equal to 1,000 milligrams. Explanation for other choices: A: 1 mg - This is incorrect as 1 mg is one-thousandth of a gram, not the other way around. B: 10 mg - This is incorrect as it is too small to be equivalent to 1 gram. C: 100 mg - This is incorrect as it is one-tenth of 1 gram, not the correct conversion.

Question 2 of 5

What is the formula for calculating the volume of a solid object?

Correct Answer: B

Rationale: The correct formula for calculating the volume of a solid object is V = L x W x H. This formula represents the length (L), width (W), and height (H) of the object multiplied together to obtain the volume. Each dimension contributes to the overall volume of the object, making this formula accurate and comprehensive. Explanation for incorrect choices: A: V = W/L - This formula represents the ratio of width to length, not the volume of a solid object. C: V = W/H - This formula represents the ratio of width to height, not the volume of a solid object. D: V = L/W - This formula represents the ratio of length to width, not the volume of a solid object.

Question 3 of 5

Convert 0.5 centimeters to millimeters.

Correct Answer: A

Rationale: To convert centimeters to millimeters, you multiply by 10 since 1 cm = 10 mm. Therefore, 0.5 cm * 10 mm/cm = 5 mm. Choice A (5 mm) is correct. Choice B (0.5 mm) is incorrect as it represents the original value in millimeters. Choice C (50 mm) is incorrect as it is 10 times greater than the correct value. Choice D (0.05 mm) is incorrect as it is 100 times smaller than the correct value.

Question 4 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.

Question 5 of 5

How many yards are in one mile?

Correct Answer: A

Rationale: Certainly! The correct answer is A: 1760 yards in one mile. This is because there are 1760 yards in a mile, as defined by the international yard agreement. This conversion is widely accepted and used in various fields. Choices B, C, and D are incorrect as they do not align with the standard conversion of yards to a mile. B, C, and D do not accurately reflect the established measurement and would lead to incorrect calculations in real-world scenarios.
