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: B

Rationale: To convert centimeters to millimeters, we multiply by 10 since there are 10 millimeters in 1 centimeter. Therefore, 5 cm x 10 = 50 mm. Thus, the correct answer is A. Option B (500 mm) is incorrect as it is the result of multiplying 5 cm by 100 instead of 10. Option C (5 mm) is incorrect as it represents the original value in centimeters, not the converted value in millimeters. Option D (500 cm) is incorrect as it is the original value in centimeters, not the converted value in millimeters.

Correct Answer: D

Rationale: To convert mg to mcg, you multiply by 1000. Therefore, 0.075 mg x 1000 = 75 mcg. Correct Answer: D. Option A is incorrect as it is the same unit, not converted. Option B is 10 times the correct answer. Option C is 100 times the correct answer.

Correct Answer: B

Rationale: The correct answer is B: 1,000 mg. There are 1,000 milligrams in 1 gram. This is because the prefix "milli-" represents one thousandth, so 1 gram is equal to 1,000 milligrams. Choice A (100 mg) is incorrect because it represents only a hundredth of a gram. Choice C (1 mg) is incorrect as it is only one thousandth of a gram. Choice D (10,000 mg) is incorrect as it is actually 10 grams, not 1 gram.
