Nursing Metric Conversion

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: The correct answer is B: 15 ml. A standard tablespoon is equivalent to 15 ml. This is a standard measurement in culinary and pharmaceutical fields. A tablespoon is commonly used for measuring liquid ingredients and medications. Choice A (10 ml) and Choice D (20 ml) are incorrect as they do not correspond to the standard measurement of a tablespoon. Choice C (5 ml) is also incorrect as it is too low to be the equivalent of a tablespoon. Therefore, B is the correct answer.

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: A

Rationale: Step 1: Convert 0.25 mg to mcg: 0.25 mg * 1000 mcg/mg = 250 mcg Step 2: Compare the converted value (250 mcg) to 250 mcg. Step 3: Since the converted value matches 250 mcg, the statement "0.25 mg is equal to 250 mcg" is TRUE. Summary: - Option B (FALSE) is incorrect because the conversion shows they are equal. - Option C (Sometimes) doesn't apply as the conversion is a precise equivalence. - Option D (None of the above) is incorrect as option A is true based on the 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.
