Metric Conversions for Nursing

Correct Answer: A

Rationale: The correct answer is A: 1.06 quarts. To convert liters to quarts, we use the conversion factor 1 liter = 1.05668821 quarts. Therefore, 2 liters would be approximately 2.11337642 quarts, which can be rounded to 1.06 quarts. The other choices are incorrect because B (0.5 quarts), C (2.1 quarts), and D (4 quarts) do not accurately represent the conversion of 2 liters to quarts based on the conversion factor.

Correct Answer: A

Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in 1 liter. So, 2500 milliliters ÷ 1000 = 2.5 liters (Option A). Option B (25 liters) is 10 times the correct answer. Option C (0.25 liters) is dividing by 10 instead of 1000. Option D (250 liters) is multiplying by 100 instead of dividing by 1000.

Correct Answer: A

Rationale: The correct answer is A: 100 g. To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in a kilogram. Therefore, 0.1 kg x 1000 = 100 g. Choice B (10 g) is incorrect as it represents 0.01 kg. Choice C (1 g) is incorrect as it represents 0.001 kg. Choice D (0.1 g) is incorrect as it is the same value as the original measurement in kilograms.

Correct Answer: A

Rationale: The conversion factor from milliliters to liters is 0.001 liters. This is because there are 1000 milliliters in 1 liter. To convert milliliters to liters, you need to divide the number of milliliters by 1000. Therefore, 1 milliliter is equal to 0.001 liters. Summary: Choice A (0.001 liters) is correct because it accurately reflects the conversion factor. Choices B, C, and D are incorrect as they do not align with the correct conversion ratio of 1 liter being equivalent to 1000 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.
