Nursing Metric Conversions

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.

Correct Answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter equals 1000 milliliters. So, 0.2 liters x 1000 = 200 milliliters, making choice B the correct answer. Choice A is incorrect as it represents 0.02 liters. Choice C is incorrect as it represents 0.002 liters. Choice D is incorrect as it represents 2 liters, not 0.2 liters.

Correct Answer: B

Rationale: The correct answer is B: 500 ml. To convert liters to milliliters, you need to remember that 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters is equal to 0.5 * 1000 = 500 milliliters. Option A (50 ml) is incorrect as it represents 0.05 liters, Option C (5 ml) is incorrect as it represents 0.005 liters, and Option D (0.5 ml) is incorrect as it represents 0.0005 liters.

Correct Answer: B

Rationale: The correct answer is B: 1,000 liters. The prefix "kilo-" represents 1,000 units. Therefore, 1 kiloliter is equal to 1,000 liters. Rationale: 1 kiloliter = 1,000 liters A: 100 liters - Incorrect, not equivalent to a kiloliter. C: 10 liters - Incorrect, too small to be a kiloliter. D: 10,000 liters - Incorrect, greater than the value of a kiloliter.

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.
