Nursing Metric Conversion

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.

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: 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: A

Rationale: The prefix kilo- in the metric system represents the factor of 10^3. Kilo- means one thousand, so when used in conjunction with a base unit, it signifies that the value is being multiplied by 1000. For example, 1 kilometer is equal to 1000 meters. Therefore, the correct answer is A: 10^3. Choice B (10^2) is incorrect because this factor corresponds to the prefix hecto-, not kilo-. Choice C (10^4) is incorrect as it does not align with the meaning of kilo-, which specifically denotes a factor of 10^3. Choice D (10^6) is incorrect as it represents the prefix mega-, which signifies a factor of 10^6.

Correct Answer: A

Rationale: To convert 0.5 L to mL, you multiply by 1000 since there are 1000 mL in 1 L. 0.5 L * 1000 = 500 mL. Therefore, the correct answer is A: 500 mL. Option B, C, and D are incorrect as they do not follow the correct conversion factor.
