Metric Conversions for Nursing

Correct Answer: B

Rationale: To convert 0.1 liter to milliliters, you need to know that 1 liter is equal to 1000 milliliters. So, to convert 0.1 liter, you multiply 0.1 by 1000, which equals 100 milliliters. Therefore, the correct answer is B: 100 ml. Choice A (10 ml) is incorrect because it doesn't consider the conversion factor between liters and milliliters. Choice C (1000 ml) is incorrect as it represents 1 liter, not 0.1 liter. Choice D (1 ml) is incorrect as it is too small of a value for 0.1 liter.

Correct Answer: B

Rationale: To convert ounces to milliliters, we need to know that 1 ounce is approximately equal to 29.57 milliliters. Therefore, the closest option to this conversion is B: 30 ml. Choices A, C, and D are not correct as they do not match the accurate conversion rate. A (20 ml) is too low, C (40 ml) is too high, and D (50 ml) is also too high. Therefore, the correct answer is B (30 ml) as it is the closest approximation to the actual conversion rate of 1 ounce to milliliters.

Correct Answer: A

Rationale: To convert 0.125 to a fraction, we observe that the decimal has 3 decimal places, so the denominator should be 1000. Thus, 0.125 as a fraction is 125/1000, which simplifies to 1/8 by dividing both numerator and denominator by 125. Therefore, the correct answer is A: 1/8. Option B: 1/4 is incorrect because 0.125 is smaller than 0.25. Option C: 1/2 is incorrect as 0.125 is smaller than 0.5. Option D: 1/16 is incorrect as it is too small to represent 0.125.

Correct Answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters x 1000 = 500 ml. Choice A (500 ml) is correct. Choices B, C, and D are incorrect because they do not accurately convert liters to milliliters.

Correct Answer: B

Rationale: To convert pounds to ounces, you need to know that 1 pound is equal to 16 ounces. So, to convert 0.29 pounds to ounces, you multiply 0.29 by 16. This gives you 4.64 ounces, which is the correct answer (B). Choices A, C, and D are incorrect because they do not correctly apply the conversion factor of 16 ounces per pound.
