Metric Conversions for Nursing Questions

Question 1 of 5

What does 'g' stand for in the metric system?

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.

Question 2 of 5

Convert 0.875 to a fraction,

Correct Answer: A

Rationale: To convert 0.875 to a fraction, we first note that the decimal places indicate the denominator. Since there are three decimal places, the denominator is 10^3 = 1000. Then, 0.875 = 875/1000, which simplifies to 7/8 by dividing both the numerator and denominator by 125. Therefore, the correct answer is A (7/8). The other choices are incorrect because B (8/7) is the reciprocal of the correct answer, C (3/4) and D (9/10) do not equal 0.875.

Question 3 of 5

How many quarts are in 1 gallon?

Correct Answer: B

Rationale: The correct answer is B: 4 quarts. There are 4 quarts in 1 gallon because a quart is a unit of volume equal to a quarter of a gallon. Therefore, when you multiply 1 gallon by 4 quarts per gallon, you get 4 quarts. Choice A (2 quarts) is incorrect because 2 quarts is only half of a gallon. Choice C (3 quarts) is incorrect because 3 quarts is three-quarters of a gallon. Choice D (1 quart) is incorrect because 1 quart is only a quarter of a gallon.

Question 4 of 5

How many millimeters are in 5 centimeters?

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.

Question 5 of 5

Convert 0.0345 kilograms to grams (g).

Correct Answer: B

Rationale: To convert from kilograms to grams, you multiply the value in kilograms by 1000 since there are 1000 grams in one kilogram. Therefore, 0.0345 kg * 1000 = 34.5 grams. Choice B (34.5 grams) is correct. Choices A, C, and D are incorrect because they do not correctly convert kilograms to grams. Choice A is off by a factor of 10, choice C is off by a factor of 100, and choice D is off by a factor of 1000.
