Nursing Metric Conversion
1. How many pints are in one quart?
- A. 1 pint
- B. 2 pints
- C. 3 pints
- D. 4 pints
Correct answer: B
Rationale: The correct answer is B: 2 pints. There are 2 pints in one quart. A quart is equivalent to 2 pints, so each quart contains 2 pints. Choice A, 1 pint, is incorrect because a quart consists of more than 1 pint. Choice C, 3 pints, and Choice D, 4 pints, are also incorrect as they do not accurately represent the conversion of quarts to pints.
2. What does 'mg' stand for in the metric system?
- A. microgram
- B. milligram
- C. gigabyte
- D. megagram
Correct answer: B
Rationale: 'mg' stands for milligram, which is equal to 1/1,000th of a gram. In the metric system, 'microgram' (choice A) is represented by 'mcg', 'gigabyte' (choice C) is a unit of digital information storage, and 'megagram' (choice D) is equivalent to a metric ton.
3. How many meters are in one kilometer?
- A. 100 meters
- B. 1000 meters
- C. 500 meters
- D. 2000 meters
Correct answer: B
Rationale: The correct answer is B: 1000 meters. One kilometer is equivalent to 1000 meters. Therefore, 1000 meters is the accurate conversion from kilometers to meters. Choices A, C, and D are incorrect. Choice A (100 meters) is incorrect as it represents 1/10th of a kilometer. Choice C (500 meters) is incorrect as it is half the value of a kilometer. Choice D (2000 meters) is incorrect as it exceeds the value of a kilometer.
4. What does 'L' stand for in the metric system?
- A. liter
- B. log
- C. link
- D. lever
Correct answer: A
Rationale: In the metric system, 'L' stands for liter, which is the base unit for liquid volume. The other choices are incorrect: 'B' log is not a standard metric unit, 'C' link is a unit of length in the Imperial system, and 'D' lever is not a metric unit but a simple machine.
5. Is 0.25 mg equal to 250 mcg?
- A. TRUE
- B. FALSE
- C. Sometimes
- D. None of the above
Correct answer: A
Rationale: The correct answer is A: TRUE. 0.25 mg is indeed equal to 250 mcg. This conversion is obtained by multiplying 0.25 mg by 1000 to convert it to micrograms. In pharmaceuticals, it is crucial to understand and convert between different dosage units accurately. Choice B is incorrect as the two quantities are equivalent. Choice C, 'Sometimes,' is misleading as the conversion from milligrams to micrograms follows a consistent ratio. Choice D, 'None of the above,' is incorrect as there is a definitive equivalence between the provided quantities.
