Metric Conversions for Nursing

1. How many mcg are there in 0.2 mg?

Correct answer: B

Rationale: To convert milligrams to micrograms, you need to multiply by 1000 since 1 mg is equal to 1000 mcg. Therefore, 0.2 mg is equivalent to 200 mcg. It is crucial to understand this conversion to ensure precise medication dosages. Choice A is incorrect because it does not account for the conversion factor of 1000 between milligrams and micrograms. Choice C is incorrect as it represents the conversion of grams to micrograms. Choice D is incorrect as it does not consider the conversion factor from milligrams to micrograms.

2. How many centimeters are in 1 inch?

Correct answer: A

Rationale: The correct answer is A: 2.54 cm. One inch is equivalent to 2.54 centimeters. This conversion factor is commonly used when converting measurements between the metric and imperial systems. Choice B (3 cm) is incorrect as it is not the accurate conversion factor for 1 inch. Choice C (2 cm) is also incorrect as it does not reflect the correct conversion. Choice D (1 cm) is incorrect as it inaccurately states the conversion value for 1 inch.

3. What is 0.5 liters to milliliters?

Correct answer: A

Rationale: The question asks for the conversion of 0.5 liters to milliliters. The correct answer is 500 ml, which is derived from the standard conversion factor where 1 liter is equal to 1000 milliliters. Choice B, 50 ml, is incorrect as it represents the conversion of 0.05 liters to milliliters. Choice C, 5 ml, is incorrect as it corresponds to the conversion of 0.005 liters to milliliters. Choice D, 0.5 ml, is incorrect as it is the same value given in the question but in milliliters.

4. Convert 0.20 liters to milliliters. What is the equivalent volume?

Correct answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in 1 liter. So, 0.20 liters x 1000 = 200 milliliters. This makes choice A, '200 ml,' the correct answer. Choices B, C, and D are incorrect because they do not reflect the correct conversion factor from liters to milliliters.

5. How many grams are in 0.5 kilograms?

Correct answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in 1 kilogram. Therefore, 0.5 kilograms is equal to 500 grams (0.5 x 1000 = 500). Choice A (50 grams) is incorrect as it is the result of multiplying by 10 instead of 1000. Choice C (5,000 grams) is incorrect as it is the result of adding an extra zero. Choice D (0.5 grams) is incorrect as it represents the original amount in grams, not the converted amount.
