Nursing Metric Conversion

Correct Answer: A

Rationale: To convert 0.2 mg to mcg, we need to remember that 1 mg is equal to 1000 mcg. So, to convert 0.2 mg to mcg, we multiply 0.2 by 1000, which gives us 200 mcg. Therefore, the correct answer is A: 200 mcg. Incorrect answers: B: 20 mcg - Incorrect because it does not account for the correct conversion factor of 1000 mcg per 1 mg. C: 2000 mcg - Incorrect as it incorrectly multiplies 0.2 mg by 1000 twice. D: 2 mcg - Incorrect as it does not consider the correct conversion of 0.2 mg to mcg.

Correct Answer: A

Rationale: To convert liters to milliliters, we know that 1 liter is equal to 1000 milliliters. Therefore, 0.6 liters would be equal to 0.6 x 1000 = 600 milliliters. This makes choice A (600 ml) the correct answer. Choices B, C, and D are incorrect because they do not follow the correct conversion factor of 1 liter to 1000 milliliters. Choice B (60 ml) is ten times less than the correct answer, choice C (6 ml) is one hundred times less, and choice D (0.6 ml) is one thousand times less than the correct conversion.

Correct Answer: B

Rationale: To convert kilometers to meters, you multiply by 1000. Therefore, to find how many meters are in 3 kilometers, you would multiply 3 by 1000, resulting in 3,000 meters. Choice B is correct. Choices A, C, and D are incorrect because they do not correctly apply the conversion factor of 1000 for converting kilometers to meters.

Correct Answer: C

Rationale: To express 0.02 as a ratio, we need to convert it to a fraction: 0.02 = 2/100. Simplifying this fraction gives us 2:100, which is the same as 2/100 or 1/50. Therefore, the correct ratio for 0.02 is 2:100 (C). The other choices are incorrect because: A: 1:50 - Incorrect, as 0.02 is equivalent to 2:100, not 1:50. B: 1:20 - Incorrect, as 0.02 is equivalent to 2:100, not 1:20. D: 4:20 - Incorrect, as 0.02 simplifies to 2:100, not 4:20.
