Nursing Metric Conversion

Correct Answer: B

Rationale: To convert from liters to milliliters, you multiply by 1000 since there are 1000 milliliters in 1 liter. So, 0.5 liters x 1000 = 500 ml. Therefore, the correct answer is B. Choice A is incorrect because 0.5 liters is not equal to 50 ml. Choice C is incorrect because 0.5 liters is not equal to 5 ml. Choice D is incorrect because 0.5 liters is not equal to 0.5 ml.

Correct Answer: A

Rationale: To convert 0.5 L to mL, you multiply by 1000 since there are 1000 mL in 1 L. 0.5 L * 1000 = 500 mL. Therefore, the correct answer is A: 500 mL. Option B, C, and D are incorrect as they do not follow the correct conversion factor.

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: B

Rationale: To convert milliliters to liters, we divide by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 3450 milliliters / 1000 = 3.45 liters. Choice B is correct. Choice A is incorrect as it is off by a factor of 10. Choice C is incorrect as it is off by a factor of 100. Choice D is incorrect as it is off by a factor of 1000.

Correct Answer: B

Rationale: The correct answer is B: 2 pints in one quart. A quart is equivalent to 2 pints. This is because there are 2 pints in a quart by definition. To convert pints to quarts, you divide the number of pints by 2. Therefore, the correct answer is 2 pints. Choices A, C, and D are incorrect because they do not align with the conversion factor of 2 pints in one quart. Answer A is too low, C is too high, and D is also too high based on the conversion factor.
