Nursing Metric Conversion - Nurselytic

Correct Answer: B

Rationale:
To convert 0.2 liters to milliliters, you need to multiply by 1,000 because there are 1,000 milliliters in a liter. So, 0.2 * 1,000 = 200 milliliters.
Therefore, the correct answer is 200 ml.
Choice A (20 ml) is incorrect because it represents 0.02 liters, not 0.2 liters.
Choice C (2 ml) is incorrect as it represents 0.002 liters.
Choice D (2000 ml) is incorrect as it represents 2 liters, not 0.2 liters.

Correct Answer: B

Rationale: In this nursing metric conversion question, the correct answer is
B) 500 ml. The rationale behind this is based on the relationship between liters and milliliters in the metric system.


To convert from liters to milliliters, you need to know that 1 liter is equal to 1000 milliliters.
Therefore, 0.5 liters would be equal to 0.5 x 1000 = 500 milliliters.

Option
A) 50 ml is incorrect because it represents 0.05 liters, not 0.5 liters. Option
C) 5 ml is even smaller and represents 0.005 liters. Option
D) 0.5 ml is too small and represents only half of a milliliter, not 0.5 liters.

Understanding metric conversions is crucial in nursing to ensure accurate medication dosages, fluid intake measurements, and other clinical calculations. Nurses must be proficient in converting between different units to prevent errors that could potentially harm patients. This question reinforces the importance of mastering basic metric conversions in healthcare settings.

Correct Answer: B

Rationale:
To convert 0.004 to a ratio, first express it as a fraction by writing it as 4/1000. Simplifying this fraction gives 1/250.
Therefore, 0.004 as a ratio is 1:250.
Choice A (5:10) simplifies to 1:2, not equivalent to 0.004.
Choice C (7:28) does not simplify to a value close to 0.004.
Choice D (4:00) is not a valid ratio representation of 0.004.

Correct Answer: A

Rationale:
To convert micrograms (mcg) to milligrams (mg), you need to divide by 1000.
Therefore, 0.05 mcg equals 0.00005 mg. This conversion is crucial in the medical field to ensure accurate dosing.
Choice B, 0.0005 mg, is incorrect as it represents 0.5 mcg.
Choice C, 0.005 mg, is the equivalent of 5 mcg.
Choice D, 0.05 mg, actually represents 50 mcg. It's important to pay attention to decimal placement and unit conversions to avoid medication errors.

Correct Answer: A

Rationale:
To convert 0.6 liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in a liter.
Therefore, 0.6 liters equals 600 milliliters.
Choice B (60 ml) is incorrect as it is a conversion of 0.06 liters, not 0.6 liters.
Choice C (6 ml) is incorrect as it represents a conversion of 0.006 liters, not 0.6 liters.
Choice D (0.6 ml) is incorrect as it is the original amount in milliliters, not the converted amount from liters.
