Nursing Metric Conversion

Correct Answer: C

Rationale: The correct answer is C because 1 liter is equivalent to 1.057 quarts. To convert liters to quarts, we know that 1 liter is approximately equal to 1.057 quarts. This conversion is accurate because it reflects the actual conversion factor between liters and quarts. A: 1 inch = 2.54 cm, not 2.5 cm. B: 1 meter = 39.37 inches, not an incorrect conversion but not the most accurate one. D: 1 gram = 1000 milligrams, not 100 milligrams. In summary, choices A, B, and D are incorrect due to inaccurate conversion factors, whereas choice C is correct as it provides the accurate conversion between liters and quarts.

Correct Answer: A

Rationale: To convert 0.3 ml to tsp, we need to know that 1 ml is approximately 0.2 tsp. Therefore, 0.3 ml is 0.3 * 0.2 = 0.06 tsp. This is why choice A (0.06 tsp) is correct. Choices B, C, and D are incorrect because they do not follow the correct conversion ratio of 1 ml to 0.2 tsp. B is too high, C is double the correct answer, and D is the same as the original measurement in ml.

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: 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: 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.
