Metric Conversions for Nursing

Correct Answer: A

Rationale: To convert kilometers to meters, you need to multiply by 1000 since 1 kilometer is equal to 1000 meters. So, 1.5 kilometers x 1000 = 1500 meters, which is choice A. Choice B (150 meters) is incorrect as it is the result if you mistakenly multiplied by 100 instead of 1000. Choice C (15,000 meters) is incorrect as it is the result of multiplying by 10,000. Choice D (1.5 meters) is incorrect as it represents the original distance in meters, not the converted value.

Correct Answer: A

Rationale: To convert grams to milligrams, you need to multiply by 1000 since 1 g = 1000 mg. Therefore, 0.04 g * 1000 = 40 mg. Thus, the correct answer is A: 40 mg. Choice B is incorrect as it is 10 times more than the correct answer. Choice C is incorrect as it is 10 times less than the correct answer. Choice D is incorrect as it is 100 times less than the correct answer.

Correct Answer: B

Rationale: To convert grams to ounces, we need to know that 1 ounce is approximately equal to 28.35 grams. Therefore, 1 gram is equal to 1/28.35 ounces, which is approximately 0.035 ounces. So, the correct answer is B. Incorrect Choices: A: 0.015 ounces - This is too low, as 1 gram is closer to 0.035 ounces. C: 0.045 ounces - This is too high, as 1 gram is closer to 0.035 ounces. D: 0.055 ounces - This is also too high, as 1 gram is closer to 0.035 ounces.

Correct Answer: B

Rationale: To convert kilometers to meters, we need to multiply by 1000 since there are 1000 meters in 1 kilometer. Therefore, 0.345 km * 1000 = 345 meters. Choice B, 345 meters, is the correct answer. Choice A (3.45 m) is incorrect as it doesn't account for the conversion factor of 1000. Choice C (345 cm) is incorrect as it converts to centimeters instead of meters. Choice D (345 m) is incorrect as it matches the correct answer but lacks the necessary conversion step.
