Nursing Metric Conversions Questions

Question 1 of 5

What is 0.45 liters in milliliters?

Correct Answer: A

Rationale: To convert liters to milliliters, we multiply the value by 1000 because 1 liter equals 1000 milliliters. Therefore, 0.45 liters is equal to 0.45 x 1000 = 450 milliliters. Choice A (450 ml) is correct. Choices B, C, and D are incorrect because they do not follow the correct conversion factor from liters to milliliters.

Question 2 of 5

How many micrograms (mcg) are equivalent to 0.5 milligrams (mg)?

Correct Answer: A

Rationale: To convert milligrams (mg) to micrograms (mcg), you multiply by 1000 because 1 mg = 1000 mcg. So, to convert 0.5 mg to mcg, you multiply 0.5 by 1000, which equals 500 mcg. Therefore, the correct answer is A: 500 mcg. Choice B (50 mcg) is incorrect as it results from multiplying by 100 instead of 1000. Choice C (5 mcg) is incorrect as it results from multiplying by 10 instead of 1000. Choice D (0.5 mcg) is incorrect as it does not involve any conversion from milligrams to micrograms.

Question 3 of 5

Convert 3,450 grams to milligrams (mg).

Correct Answer: B

Rationale: To convert grams to milligrams, you need to multiply by 1,000 since 1 gram is equal to 1,000 milligrams. Therefore, to convert 3,450 grams to milligrams, you multiply 3,450 by 1,000, which equals 3,450,000 mg. The correct answer is B. Explanation for other choices: A: 34,500 mg - This is incorrect as it only multiplies by 10 (not 1,000). C: 3,450 mg - This is incorrect as it does not convert grams to milligrams. D: 3,450,000 mg - This is incorrect as it repeats the original value in milligrams.

Question 4 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.

Question 5 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.
