Nursing Metric Conversions

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.

Correct Answer: B

Rationale: The correct answer is B: grams. Grams are the base unit for mass in the metric system. The metric system is based on powers of ten, making it easy to convert between units. Milligrams (A) are smaller units, kilograms (C) are larger units, and tons (D) are even larger units. Grams are the most commonly used unit for measuring everyday items and are the standard unit for mass in the metric system.

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.

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.

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.
