Nursing Metric 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: C

Rationale: To convert milliliters to liters, you divide by 1000 since 1 liter equals 1000 milliliters. Therefore, 3000 milliliters divided by 1000 equals 3 liters. Choice C is correct. Choice A is incorrect as it represents 0.3 liters, which is the result of dividing by 10. Choice B is incorrect as it represents 30 liters, which is the result of multiplying by 10. Choice D is incorrect as it represents 0.03 liters, which is the result of dividing by 100.

Correct Answer: B

Rationale: To convert kilograms to grams, we need to multiply by 1000 since 1 kilogram equals 1000 grams. Therefore, 0.5 kilograms x 1000 = 500 grams. This is why choice B, 500 grams, is correct. Choice A, 50 grams, is incorrect as it is the result of multiplying by 10 instead of 1000. Choice C, 5,000 grams, is incorrect as it is the result of multiplying by 10,000 which is not the correct conversion factor. Choice D, 0.5 grams, is incorrect as it is the original amount in grams, not the converted amount from kilograms.

Correct Answer: D

Rationale: To convert millimeters to centimeters, we divide by 10 since there are 10 millimeters in 1 centimeter. Therefore, 25 mm / 10 = 2.5 cm. The correct answer is D: 25 mm, as it represents the initial quantity to be converted. Choices A and B are incorrect as they do not follow the conversion factor. Choice C is incorrect as it represents the original unit rather than the converted unit.

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.
