Nursing Metric Conversions
1. How many milligrams are in 1 gram?
- A. 1 mg
- B. 10 mg
- C. 100 mg
- D. 1,000 mg
Correct answer: D
Rationale: The correct answer is D: 1,000 mg. This is because 1 gram is equivalent to 1,000 milligrams. To convert grams to milligrams, you multiply by 1,000. Choices A, B, and C are incorrect. Choice A (1 mg) is the smallest unit, and it would take 1,000 of these to make 1 gram. Choice B (10 mg) is also too small, as it would require 100 of these to equal 1 gram. Choice C (100 mg) is closer, but it still falls short of the correct conversion, which is 1,000 mg in 1 gram.
2. How many ounces is equal to 1 gram?
- A. 0.015 ounces
- B. 0.035 ounces
- C. 0.045 ounces
- D. 0.055 ounces
Correct answer: B
Rationale: To convert grams to ounces, you need to multiply the weight in grams by 0.035 to get the equivalent weight in ounces. Therefore, 1 gram is equal to 0.035 ounces. Choices A, C, and D are incorrect conversions and do not accurately represent the conversion factor from grams to ounces.
3. How many meters are equivalent to 3 kilometers?
- A. 300 meters
- B. 3,000 meters
- C. 30,000 meters
- D. 300,000 meters
Correct answer: B
Rationale: To convert from kilometers to meters, you need to multiply by 1,000 since there are 1,000 meters in a kilometer. Therefore, 3 kilometers is equal to 3,000 meters. Choices A, C, and D are incorrect because they do not correctly convert kilometers to meters.
4. What is the base unit for volume of a solid in the metric system?
- A. cubic meters
- B. meters cubed
- C. grams
- D. centimeters
Correct answer: A
Rationale: The correct answer is 'cubic meters' (A) which is the base unit for volume of a solid in the metric system. Volume is measured in cubic units (length × width × height) for solids. Choice B, 'meters cubed,' is not the standard way to express volume in the metric system. Choices C and D, 'grams' and 'centimeters,' are units of mass and length respectively, not volume.
5. How many mcg are there in 0.2 mg?
- A. 20 mcg
- B. 200 mcg
- C. 2000 mcg
- D. 2 mcg
Correct answer: B
Rationale: To convert milligrams to micrograms, you need to multiply by 1000 since 1 mg is equal to 1000 mcg. Therefore, 0.2 mg is equivalent to 200 mcg. It is crucial to understand this conversion to ensure precise medication dosages. Choice A is incorrect because it does not account for the conversion factor of 1000 between milligrams and micrograms. Choice C is incorrect as it represents the conversion of grams to micrograms. Choice D is incorrect as it does not consider the conversion factor from milligrams to micrograms.
