Nursing Metric Conversion

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: centi. The metric prefix "centi" represents 10^-2, which means one hundredth. This is because "centi" comes from the Latin word for hundred. Therefore, when using this prefix, the base unit is divided by 100. The other choices are incorrect because: B: milli represents 10^-3, which is one thousandth. C: nano represents 10^-9, which is one billionth. D: deci represents 10^-1, which is one-tenth.

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: liter. In the metric system, 'L' stands for liter, which is a unit of volume. The liter is commonly used to measure liquid volumes. The other choices, B: log, C: link, and D: lever, do not represent units of measurement in the metric system. Log is a mathematical function, link is a unit of distance in surveying, and lever is a simple machine. Therefore, the correct answer is A: liter, as it is the only choice that corresponds to a valid unit of measurement in the metric system.

Correct Answer: B

Rationale: The correct answer is B: volume. Volume refers to the amount of space an object occupies in three dimensions. It is calculated by multiplying the length, width, and height of an object. Mass (A) is the amount of matter in an object, density (C) is the mass per unit volume, and area (D) is the measurement of the surface of an object in two dimensions. Therefore, volume is the most appropriate term for describing the amount of space an object occupies.
