Metric Conversions for Nursing
1. What is 0.2 liters when converted to milliliters?
- A. 20 ml
- B. 200 ml
- C. 2 ml
- D. 2000 ml
Correct answer: B
Rationale: To convert liters to milliliters, you need to multiply by 1000, not 10000. Therefore, 0.2 liters equals 200 ml (0.2 x 1000 = 200 ml). Choice A, 20 ml, is incorrect because it's the result of multiplying by 10 instead of 1000. Choice C, 2 ml, is incorrect as it's the result of ignoring the decimal point. Choice D, 2000 ml, is incorrect because it's the result of multiplying by 10000.
2. What is 0.004 expressed as a ratio?
- A. 1:250
- B. 4:20
- C. 2:40
- D. 9:20
Correct answer: A
Rationale: The decimal 0.004 can be represented as a ratio of 4/1000, which simplifies to 1/250, making the ratio 1:250. The correct answer is A. Choices B, C, and D are incorrect because they do not reflect the correct conversion of 0.004 into a simplified ratio. Choice B simplifies to 1:5, Choice C simplifies to 1:20, and Choice D simplifies to 9:20, none of which accurately represent the ratio of 0.004.
3. What is 1500 milliliters in liters?
- A. 1.5 liters
- B. 0.15 liters
- C. 15 liters
- D. 0.015 liters
Correct answer: A
Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in 1 liter. Therefore, 1500 milliliters divided by 1000 equals 1.5 liters, making option A the correct answer. Option B, 0.15 liters, is incorrect as it would be the conversion of 150 milliliters. Option C, 15 liters, is incorrect because it would be the conversion of 15,000 milliliters. Option D, 0.015 liters, is incorrect as it would be the conversion of 15 milliliters.
4. What is the result of multiplying 0.15 by 3?
- A. 0.05
- B. 0.15
- C. 0.45
- D. 0.45
Correct answer: C
Rationale: The correct answer is C: 0.45. To find the result of multiplying 0.15 by 3, you simply multiply the two numbers together, which gives you 0.45. Choice A (0.05) is incorrect as it is the result of dividing 0.15 by 3 instead of multiplying. Choice B (0.15) is the original number being multiplied and not the result. Choice D (0.45) is the same as the correct answer but is repeated for redundancy.
5. How many milliliters are in 1 ounce?
- A. 20 ml
- B. 30 ml
- C. 40 ml
- D. 50 ml
Correct answer: B
Rationale: The correct answer is B: 30 ml. 1 ounce is equivalent to 30 milliliters. This conversion is a common one in many contexts involving liquid measurements. Choice A (20 ml), Choice C (40 ml), and Choice D (50 ml) are incorrect conversions and do not represent the accurate conversion between ounces and milliliters.
