Nursing Metric Conversion

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.

Correct Answer: B

Rationale: The correct answer is B: milligram. In the metric system, 'mg' stands for milligram, which is a unit of mass equal to one thousandth of a gram. To determine the correct answer, you need to understand the metric prefixes. 'Micro' means one millionth, 'milli' means one thousandth, 'giga' means one billion, and 'mega' means one million. Therefore, A is incorrect because 'micro' is smaller than 'milli', C is incorrect because 'giga' is much larger than 'milli', and D is incorrect because 'megagram' is a unit equal to one million grams, not milligrams.

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: C

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in 1 kilogram. So, 5 kilograms x 1000 = 5000 grams, which makes choice C the correct answer. Choices A, B, and D are incorrect as they do not correctly apply the conversion factor of 1000.

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.
