Nursing Metric Conversion
1. In the metric system, what factor does the prefix kilo- represent?
- A. 10^3
- B. 10^2
- C. 10^4
- D. 10^6
Correct answer: A
Rationale: The prefix 'kilo-' in the metric system signifies a factor of 1000, which is equivalent to 10^3. Therefore, when using the prefix 'kilo-', it implies multiplying the base unit by 1000. For instance, one kilometer is equal to 1000 meters. Choices B, C, and D are incorrect as they do not accurately represent the factor associated with the prefix 'kilo-'.
2. How many milliliters are in 1.5 liters?
- A. 15 mL
- B. 1,500 mL
- C. 150 mL
- D. 150,000 mL
Correct answer: B
Rationale: To convert liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in a liter. Therefore, 1.5 liters x 1,000 = 1,500 milliliters. Choice A, 15 mL, is incorrect as it represents the conversion of 0.015 liters. Choice C, 150 mL, is incorrect as it represents the conversion of 0.15 liters. Choice D, 150,000 mL, is incorrect as it represents the conversion of 150 liters.
3. How many centimeters are in 1 meter?
- A. 10 cm
- B. 100 cm
- C. 1,000 cm
- D. 10,000 cm
Correct answer: B
Rationale: The correct answer is B: 100 cm. 1 meter is equivalent to 100 centimeters. Choice A (10 cm) is incorrect as it represents the conversion of decimeters to centimeters. Choice C (1,000 cm) is incorrect as it represents the conversion of meters to millimeters. Choice D (10,000 cm) is incorrect as it represents the conversion of meters to centimeters with an extra zero.
4. Which conversion is accurate?
- A. 1 inch = 2.5 cm
- B. 1 meter = 39.37 inches
- C. 1 liter = 1.057 quarts
- D. 1 gram = 100 milligrams
Correct answer: C
Rationale: The correct answer is C: '1 liter = 1.057 quarts.' This conversion is accurate as it reflects the precise relationship between liters and quarts, where 1 liter is slightly more than a quart. Choice A is incorrect because 1 inch is approximately equal to 2.54 cm, not 2.5 cm. Choice B is incorrect as 1 meter is equivalent to approximately 39.37 inches, not exactly. Choice D is also inaccurate as 1 gram is equal to 1000 milligrams, not 100 milligrams.
5. 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.
