Metric Conversions for Nursing

Correct Answer: C

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in 1 kilogram. So, 1.25 kg x 1000 = 1250 grams, which is choice C. Choice A (12.5 grams) is incorrect as it is 10 times less than the correct answer. Choice B (125 grams) is incorrect as it is missing a zero. Choice D (1250 mg) is incorrect as it is in milligrams, not grams.

Correct Answer: A

Rationale: The correct answer is A: gram. In the metric system, 'g' stands for gram, which is a unit of mass. This is the correct answer because gram is the standard unit of mass in the metric system, commonly used for measuring small weights. The other choices are incorrect because: B: grain is a unit of weight used in the imperial system, not the metric system. C: goose is not a unit of measurement in any system. D: grammage refers to the weight per unit area of paper or similar material, not a standard unit of mass in the metric system.

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: B

Rationale: To convert 0.16 inches to a fraction, we can write it as 16/100 or 4/25. Both 16/100 and 4/25 are equivalent to 0.16. Therefore, the correct answer is B: 0.16 inches. Option A (0.016 inches) is incorrect as it is one-tenth of the correct value. Option C (1.6 inches) is incorrect as it is ten times the correct value. Option D (16 inches) is incorrect as it is one hundred times the correct value.

Correct Answer: A

Rationale: To convert kilometers to meters, you need to multiply by 1000 since 1 kilometer is equal to 1000 meters. So, 1.5 kilometers x 1000 = 1500 meters, which is choice A. Choice B (150 meters) is incorrect as it is the result if you mistakenly multiplied by 100 instead of 1000. Choice C (15,000 meters) is incorrect as it is the result of multiplying by 10,000. Choice D (1.5 meters) is incorrect as it represents the original distance in meters, not the converted value.
