Metric Conversions for Nursing Questions

Question 1 of 5

How many milligrams (mg) are equal to 1 gram?

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.

Question 2 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 3 of 5

How many centimeters are in 4 meters?

Correct Answer: B

Rationale: To convert meters to centimeters, you multiply by 100 (1 meter = 100 cm). So, 4 meters x 100 cm/meter = 400 cm (Choice B). Choice A (40 cm) is incorrect as it represents 0.4 meters. Choice C (4 cm) is incorrect as it corresponds to 0.04 meters. Choice D (0.4 cm) is incorrect as it is 0.004 meters. Therefore, the correct answer is B (400 cm) as it accurately represents 4 meters in centimeters.

Question 4 of 5

Convert 1.5 kilometers to meters.

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.

Question 5 of 5

How many milliliters are in 2 liters?

Correct Answer: A

Rationale: To convert liters to milliliters, you multiply by 1000 because 1 liter = 1000 milliliters. Therefore, 2 liters x 1000 = 2000 milliliters. This is why choice A (2000 mL) is correct. Choices B, C, and D are incorrect because they do not correctly convert 2 liters to milliliters using the conversion factor of 1000. Choice B (20,000 mL) is 10 times the correct answer, choice C (200 mL) is 10 times less, and choice D (2 mL) is 1000 times less than the correct answer.
