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: B

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in 1 kilogram. Therefore, 35.40 kg x 1000 = 35,400 g (Choice B). This is the correct answer because it correctly applies the conversion factor. Choices A, C, and D are incorrect as they do not correctly convert kilograms to grams. Choice A is too small, Choice C is missing a zero, and Choice D incorrectly divides instead of multiplies.

Correct Answer: B

Rationale: To convert milliliters to liters, we divide by 1000 since there are 1000 milliliters in a liter. So, 750 milliliters ÷ 1000 = 0.75 liters. Therefore, the correct answer is B. Choice A is incorrect as it incorrectly moves the decimal point. Choices C and D are incorrect as they incorrectly add extra zeros and move the decimal point in the wrong direction.

Correct Answer: A

Rationale: The correct answer is A: millimeter. In the metric system, 'mm' stands for millimeter, which is a unit of length equal to one thousandth of a meter. This is the correct answer because "milli-" is a prefix in the metric system that denotes one thousandth. Megabyte (B) is a unit of digital information storage, not length. Millipede (C) refers to a type of arthropod, not a unit of measurement. Metered (D) is not a recognized unit in the metric system for length.

Correct Answer: B

Rationale: The correct answer is B: 5280 feet in one mile. This is because 1 mile is equivalent to 5280 feet. This conversion is a standard unit of measurement in the Imperial system. Choice A, 5000 feet, is too low and does not accurately represent the length of a mile. Choice C, 5300 feet, and choice D, 5500 feet, are both higher than the actual value of 5280 feet, making them incorrect. To convert miles to feet, we multiply by the conversion factor of 5280.
