Nursing Metric Conversion

Correct Answer: A

Rationale: To convert liters to milliliters, we know that 1 liter is equal to 1000 milliliters. Therefore, to convert 0.04 liters to milliliters, we multiply 0.04 by 1000, which equals 40 milliliters. This makes choice A the correct answer. Choices B, C, and D are incorrect because they do not correctly convert 0.04 liters to milliliters using the conversion factor of 1 liter = 1000 milliliters.

Correct Answer: A

Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in 1 liter. Therefore, 1500 milliliters divided by 1000 equals 1.5 liters. Choice A (1.5 liters) is correct because it accurately represents the conversion. Choices B, C, and D are incorrect because they do not follow the correct conversion factor of dividing by 1000. Choice B (0.15 liters) is one decimal place off, choice C (15 liters) is an order of magnitude too high, and choice D (0.015 liters) is two decimal places off.

Correct Answer: A

Rationale: To convert micrograms (mcg) to milligrams (mg), we need to remember that 1 mcg is equal to 0.001 mg. Therefore, to convert 0.05 mcg to mg, we multiply 0.05 by 0.001 which gives us 0.00005 mg. This makes choice A the correct answer. Choices B, C, and D are incorrect because they do not correctly convert micrograms to milligrams based on the conversion factor of 0.001 mg per mcg.

Correct Answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters x 1000 = 500 milliliters. So, the correct answer is A: 500 ml. Explanation of other choices: B: 50 ml - Incorrect, this would be the equivalent of 0.05 liters. C: 5 ml - Incorrect, this would be the equivalent of 0.005 liters. D: 0.5 ml - Incorrect, this is the same value as the given amount in liters, not the conversion to milliliters.

Correct Answer: B

Rationale: To convert millimeters to meters, you divide by 1000 since there are 1000 millimeters in a meter. So, 354,000 mm ÷ 1000 = 354 m. Choice B is correct as it correctly converts millimeters to meters. Choice A is incorrect as it doesn't account for the conversion. Choice C is incorrect as it converts to kilometers instead of meters. Choice D is incorrect as it is a miscalculation of the conversion.
