Nursing Metric Conversion

Correct Answer: A

Rationale: To express 0.07 as a fraction, we consider the decimal places. Since there are two decimal places in 0.07, we write it as 7/100. This simplifies to 7/100 as the correct fraction. Option A is correct as it represents 0.07 accurately. Options B, C, and D are incorrect as they do not match the decimal value of 0.07. B is 1/10, C is 1/20, and D is 1/50, which are not equivalent to 0.07.

Correct Answer: C

Rationale: The correct answer is C because 1 liter is equivalent to 1.057 quarts. To convert liters to quarts, we know that 1 liter is approximately equal to 1.057 quarts. This conversion is accurate because it reflects the actual conversion factor between liters and quarts. A: 1 inch = 2.54 cm, not 2.5 cm. B: 1 meter = 39.37 inches, not an incorrect conversion but not the most accurate one. D: 1 gram = 1000 milligrams, not 100 milligrams. In summary, choices A, B, and D are incorrect due to inaccurate conversion factors, whereas choice C is correct as it provides the accurate conversion between liters and quarts.

Correct Answer: B

Rationale: To convert kilometers to meters, you multiply by 1000. Therefore, to find how many meters are in 3 kilometers, you would multiply 3 by 1000, resulting in 3,000 meters. Choice B is correct. Choices A, C, and D are incorrect because they do not correctly apply the conversion factor of 1000 for converting kilometers to meters.

Correct Answer: B

Rationale: The correct answer is B: 2 pints in one quart. A quart is equivalent to 2 pints. This is because there are 2 pints in a quart by definition. To convert pints to quarts, you divide the number of pints by 2. Therefore, the correct answer is 2 pints. Choices A, C, and D are incorrect because they do not align with the conversion factor of 2 pints in one quart. Answer A is too low, C is too high, and D is also too high based on the conversion factor.

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 milliliters. So, the correct answer is A: 500 ml. Explanation of other choices: B: 50 ml - Incorrect, this would be the equivalent of 0.05 liters. C: 5 ml - Incorrect, this would be the equivalent of 0.005 liters. D: 0.5 ml - Incorrect, this is the same value as the given amount in liters, not the conversion to milliliters.
