Nursing Metric Conversion

1. What does 'L' stand for in the metric system?

Correct answer: A

Rationale: In the metric system, 'L' stands for liter, which is the base unit for liquid volume. The other choices are incorrect: 'B' log is not a standard metric unit, 'C' link is a unit of length in the Imperial system, and 'D' lever is not a metric unit but a simple machine.

2. How many milligrams are in 2 grams?

Correct answer: B

Rationale: To convert grams to milligrams, you need to multiply by 1,000 since there are 1,000 milligrams in a gram. Therefore, 2 grams is equal to 2,000 milligrams. Choice A (200 mg) is incorrect as it represents 0.2 grams. Choice C (20 mg) is incorrect as it represents 0.02 grams. Choice D (20,000 mg) is incorrect as it represents 20 grams.

3. Is 0.25 mg equal to 250 mcg?

Correct answer: A

Rationale: The correct answer is A: TRUE. 0.25 mg is indeed equal to 250 mcg. This conversion is obtained by multiplying 0.25 mg by 1000 to convert it to micrograms. In pharmaceuticals, it is crucial to understand and convert between different dosage units accurately. Choice B is incorrect as the two quantities are equivalent. Choice C, 'Sometimes,' is misleading as the conversion from milligrams to micrograms follows a consistent ratio. Choice D, 'None of the above,' is incorrect as there is a definitive equivalence between the provided quantities.

4. What is 0.09 liters in milliliters when converted?

Correct answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in a liter. Therefore, 0.09 liters x 1,000 = 90 milliliters. Choice A, 0.09 ml, is incorrect as it represents the original volume in milliliters. Choices C and D, 900 ml and 9 ml, are incorrect as they miscalculate the conversion from liters to milliliters.

5. What unit is used to measure density in the metric system?

Correct answer: A

Rationale: Density is measured in grams per cubic meter (g/m³) in the metric system. This unit represents the amount of mass (in grams) per unit volume (cubic meter). Choice B, grams per liter (g/L), is incorrect as density is not typically measured in liters. Choice C, grams per cubic centimeter (g/cm³), is a common unit for density but not the standard SI unit. Choice D, grams per square meter (g/m²), is a unit for surface density, not volumetric density. Therefore, the correct unit for measuring density in the metric system is grams per cubic meter (g/m³).
