Nursing Metric Conversions - Nurselytic

Correct Answer: B

Rationale: The base unit for mass in the metric system is grams. Grams are the fundamental unit of mass in the metric system, representing smaller quantities than kilograms and tons. Milligrams are a smaller unit of mass, kilograms are a larger unit, and tons are even larger units.
Therefore, the correct choice is grams.

Correct Answer: A

Rationale:
To convert a decimal to a fraction, you place the decimal value over a power of 10, where the number of zeros in the denominator is equal to the number of decimal places in the decimal. In this case, 0.03 can be written as 3/100 because there are two decimal places (hundredths). This fraction is already in simplest form.
Choice B, 1/30, is incorrect as it represents 0.033 as a fraction.
Choice C, 1/3, is incorrect as it represents 0.3 as a fraction.
Choice D, 1/10, is incorrect as it represents 0.1 as a fraction.

Correct Answer: B

Rationale: The correct answer is B: '0.001 m.' The prefix 'milli' represents a factor of 10^-3, which means one millimeter (mm) is equivalent to 0.001 meters (m).
Therefore, 1 mm is equal to 0.001 m.
Choice A, '0.01 m,' is incorrect as it represents 0.01 meters, not 0.001 meters.
Choice C, '0.1 m,' is incorrect because it stands for 0.1 meters, which is 10 times greater than 1 mm.
Choice D, '1 m,' is incorrect as it represents 1 meter, which is 1000 times greater than 1 mm.

Correct Answer: C

Rationale:
To convert liters to milliliters, you need to multiply the number of liters by 1,000 because there are 1,000 milliliters in a liter.
Therefore, 0.1 liter is equal to 100 milliliters.
Choice A (1 ml) is incorrect because it represents the conversion of 0.01 liters, not 0.1 liters.
Choice B (10 ml) is incorrect as it also represents the conversion of 0.01 liters.
Choice D (1000 ml) is incorrect as it represents the conversion of 1 liter, not 0.1 liter.

Correct Answer: A

Rationale: 0.05 mg is equivalent to 50 mcg because 1 mg is equal to 1000 mcg.
To convert milligrams to micrograms, you need to multiply by 1000.
Therefore, 0.05 mg x 1000 = 50 mcg.

Choices B, C, and D are incorrect because they do not correctly convert milligrams to micrograms. Option B (500 mcg) would be the result if the conversion was done incorrectly by adding an extra zero, while options C (5 mcg) and D (0.5 mcg) are incorrect due to miscalculating the conversion factor.
