Metric Conversions for Nursing

Correct Answer: B

Rationale: To convert meters to centimeters, you multiply by 100 (1 meter = 100 cm). So, 4 meters x 100 cm/meter = 400 cm (Choice B). Choice A (40 cm) is incorrect as it represents 0.4 meters. Choice C (4 cm) is incorrect as it corresponds to 0.04 meters. Choice D (0.4 cm) is incorrect as it is 0.004 meters. Therefore, the correct answer is B (400 cm) as it accurately represents 4 meters in centimeters.

Correct Answer: C

Rationale: The correct answer is C: 2,000 mL. To convert liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in 1 liter. So, 2 liters x 1,000 mL = 2,000 mL. Explanation for Other Choices: A: 20 mL - This is incorrect as it is just 1% of 2 liters. B: 200 mL - This is also incorrect as it is 10% of 2 liters. D: 20,000 mL - This is incorrect as it is 10 times the correct answer, which is too large for 2 liters.

Correct Answer: A

Rationale: To convert 0.875 to a fraction, we note that it is 875/1000. Simplifying this gives 7/8, making A the correct answer. Choice B, 9/10, and C, 5/6, are incorrect as they do not equal 0.875 when converted to decimals. Choice D, 3/4, is also incorrect as it is not equivalent to 0.875.

Correct Answer: A

Rationale: To convert liters to milliliters, you multiply by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters is equal to 0.5 x 1000 = 500 ml. Choice A (500 ml) is correct. Choices B, C, and D are incorrect because they do not follow the correct conversion factor of 1 liter to 1000 milliliters. B (50 ml), C (5 ml), and D (0.5 ml) are not the correct conversions for 0.5 liters.

Correct Answer: A

Rationale: To convert liters to milliliters, you multiply by 1000 because 1 liter = 1000 milliliters. Therefore, 2 liters x 1000 = 2000 milliliters. This is why choice A (2000 mL) is correct. Choices B, C, and D are incorrect because they do not correctly convert 2 liters to milliliters using the conversion factor of 1000. Choice B (20,000 mL) is 10 times the correct answer, choice C (200 mL) is 10 times less, and choice D (2 mL) is 1000 times less than the correct answer.
