Metric Conversions for Nursing

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: The correct answer is A: centimeter. 'cm' stands for centimeter in the metric system. 'Centi' is a prefix that means one hundredth, so centimeter represents one hundredth of a meter. Choice B, cubic meter, is incorrect because 'cm' does not refer to volume. Choice C, cord, is a unit of measurement for stacked firewood and is not related to 'cm.' Choice D, centi, is a prefix used to indicate one hundredth, but it is not the complete unit itself.

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: B

Rationale: The correct answer is B: International System of Units (SI). This is because the SI system is the internationally recognized standard for units of measurement. It is based on seven base units, from which all other units are derived. It provides a consistent and coherent framework for measurements across different fields of science and technology. Choice A (International Measurement System) is incorrect because the official name does not include the word "measurement." Choice C (Metric Unit System) is incorrect because while the metric system is a component of the SI system, it does not encompass all the units used in the SI system. Choice D (Measurement System of Units) is incorrect as it does not accurately reflect the comprehensive nature of the SI system.
