Nursing Metric Conversions
1. How many grams are in 2 kilograms?
- A. 200 grams
- B. 2000 grams
- C. 20 grams
- D. 2 grams
Correct answer: B
Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in a kilogram. Therefore, 2 kilograms is equal to 2 x 1000 = 2000 grams. Choice A (200 grams) is incorrect as it represents the value of 0.2 kilograms. Choice C (20 grams) is incorrect as it represents the value of 0.02 kilograms. Choice D (2 grams) is incorrect as it represents the value of 0.002 kilograms.
2. What is 0.2 rounded to the nearest tenth?
- A. 0.1
- B. 0.2
- C. 0.3
- D. 0.25
Correct answer: B
Rationale: The decimal 0.2 is already at the nearest tenth, so it does not need to be rounded. Rounding to the nearest tenth means keeping one decimal place, which is already the case with 0.2. Therefore, the correct answer is 0.2, as it is already at the specified rounding point. Choices A, C, and D are incorrect because they represent values that are not the result of rounding 0.2 to the nearest tenth. 0.1 is rounding down, 0.3 is rounding up, and 0.25 is not the nearest tenth of 0.2.
3. How many centimeters are in 0.25 meters?
- A. 2.5 cm
- B. 25 cm
- C. 250 cm
- D. 0.25 cm
Correct answer: B
Rationale: To convert meters to centimeters, you need to multiply by 100 since there are 100 centimeters in a meter. Therefore, 0.25 meters x 100 = 25 centimeters. Choice A, '2.5 cm,' is incorrect as it is the result of multiplying by 10 instead of 100. Choice C, '250 cm,' is incorrect as it is the result of multiplying by 1000. Choice D, '0.25 cm,' is incorrect as it suggests the conversion is in the opposite direction, from centimeters to meters.
4. The SI prefixes micro and milli represent, respectively:
- A. 10^-6 and 10^-3
- B. 10^-9 and 10^-6
- C. 10^-12 and 10^-9
- D. 10^-15 and 10^-12
Correct answer: A
Rationale: The prefixes 'micro-' and 'milli-' represent 10^-6 and 10^-3, respectively. 'Micro-' denotes one-millionth (10^-6), while 'milli-' denotes one-thousandth (10^-3). Choice B is incorrect because it confuses the order of magnitudes for micro and milli. Choice C and D are also incorrect as they provide the wrong values for the prefixes micro and milli.
5. How many grams are in one kilogram?
- A. 100 grams
- B. 1000 grams
- C. 500 grams
- D. 2000 grams
Correct answer: B
Rationale: The correct answer is B: 1000 grams. This is because by definition, 1 kilogram is equal to 1000 grams. Choice A, 100 grams, is incorrect as it underestimates the actual conversion. Choice C, 500 grams, and Choice D, 2000 grams, are also incorrect as they do not align with the correct conversion factor of 1 kilogram to 1000 grams.
