Metric Conversions for Nursing

1. How many quarts are equivalent to 2 liters?

Correct answer: A

Rationale: To convert liters to quarts, we know that 1 liter is approximately equal to 1.06 quarts. Therefore, 2 liters would be around 2.12 quarts. However, for practical purposes, it's often rounded to 2.1 quarts. Option A, '1.06 quarts,' is the closest and most accurate approximation. Option B, '0.5 quarts,' is incorrect as it represents half of the actual conversion. Option C, '2.1 quarts,' is close but slightly higher than the actual conversion. Option D, '4 quarts,' is double the correct conversion and is therefore incorrect.

2. What is 0.025 mg in mcg?

Correct answer: A

Rationale: To convert milligrams to micrograms, you need to multiply by 1000 because there are 1000 micrograms in a milligram. Therefore, 0.025 mg x 1000 = 25 mcg. This means that the correct answer is A, 25 mcg. Choice B, 250 mcg, is incorrect because it incorrectly multiplies by 10 instead of 1000. Choice C, 2.5 mcg, is incorrect as it inaccurately divides the value by 10. Choice D, 0.25 mcg, is also incorrect as it divides the value by 100 instead of multiplying by 1000.

3. Convert 0.875 to a fraction,

Correct answer: A

Rationale: To convert 0.875 to a fraction, express it as 875\10000. Simplifying this fraction by dividing both the numerator and denominator by 125 results in 7\80.

4. What is the base unit for liquid volume in the metric system?

Correct answer: B

Rationale: The correct answer is B: Liters. In the metric system, liters are the base unit for liquid volume. Milliliters, though a metric unit, are a smaller unit of volume and not the base unit. Gallons, on the other hand, are part of the imperial system and not a metric unit for volume. Option D is a duplicate of option B, making it incorrect.

5. What is 0.04 grams converted to milligrams?

Correct answer: A

Rationale: To convert grams to milligrams, you need to multiply by 1000, not 10000. Therefore, to convert 0.04 grams to milligrams, you multiply 0.04 by 1000, which equals 40 mg. Choice A (40 mg) is the correct answer. Choice B (4 mg) is incorrect as it represents converting 0.004 grams to milligrams. Choice C (400 mg) is incorrect as it is 10 times the correct conversion. Choice D (0.4 mg) is incorrect as it is 10 times smaller than the correct conversion.
