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: 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: B

Rationale: To convert grams to kilograms, divide by 1000 since there are 1000 grams in a kilogram. So, 1500 grams / 1000 = 1.5 kg. Therefore, the correct answer is B: 1.5 kg. Incorrect choices: A: 0.15 kg - Incorrect as it is 10 times smaller than the correct answer. C: 15 kg - Incorrect as it is 10 times greater than the correct answer. D: 150 kg - Incorrect as it is 100 times greater than the correct answer.

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: A

Rationale: To express 0.07 as a fraction, we consider the decimal places. Since there are two decimal places in 0.07, we write it as 7/100. This simplifies to 7/100 as the correct fraction. Option A is correct as it represents 0.07 accurately. Options B, C, and D are incorrect as they do not match the decimal value of 0.07. B is 1/10, C is 1/20, and D is 1/50, which are not equivalent to 0.07.
