Nursing Metric Conversions - Nurselytic

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: C

Rationale:
To express 0.4 in inches, you don't need to convert it further as it is already in inches.
Therefore, the correct answer is 0.4 inches.
Choice A (0.04 inches) is incorrect as it represents a smaller quantity.
Choice B (4 inches) and
Choice D (40 inches) are incorrect as they represent larger quantities, which are not equivalent to 0.4 inches.

Correct Answer: A

Rationale:
To convert 0.004 to a ratio, we first express it as 4/1000, which simplifies to 1/250. Hence, 0.004 is equivalent to the simplified ratio of 1:250.
Choice B, 4:35, is incorrect as it does not reflect the correct conversion.
Choice C, 7:28, is incorrect because it does not represent the simplified ratio of 0.004.
Choice D, 4:00, is incorrect as it does not simplify to the original decimal value.

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.

Correct Answer: B

Rationale:
To convert liters to milliliters, you need to multiply the number of liters by 1000 because there are 1000 milliliters in 1 liter.
Therefore, 0.5 liters converts to 500 milliliters.
Choice A (50 ml) is incorrect as it is the result of multiplying by 10 instead of 1000.
Choice C (5 ml) is incorrect as it is the result of dividing by 10 instead of multiplying by 1000.
Choice D (0.5 ml) is incorrect as it represents the original quantity in milliliters, not the conversion from liters.
