Metric Conversions for Nursing Questions
Question 1 of 5
What is 0.5 liters in ml?
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.
Question 2 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 3 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 4 of 5
What is 0.1 kg in grams?
Correct Answer: A
Rationale: The correct answer is A: 100 g. To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in a kilogram. Therefore, 0.1 kg x 1000 = 100 g. Choice B (10 g) is incorrect as it represents 0.01 kg. Choice C (1 g) is incorrect as it represents 0.001 kg. Choice D (0.1 g) is incorrect as it is the same value as the original measurement in kilograms.
Question 5 of 5
What is the base unit for volume of a solid in the metric system?
Correct Answer: A
Rationale: The correct answer is A: cubic meters. Volume is a three-dimensional measurement, so the base unit for volume of a solid in the metric system is cubic meters. Cubic meters represent the amount of space that a solid occupies in three dimensions. Meters cubed (B) is not the correct term for the base unit, as cubic meters is the standard notation. Grams (C) is a unit of mass, not volume. Centimeters (D) is a unit of length, not volume. Therefore, the most appropriate and accurate base unit for volume of a solid in the metric system is cubic meters.
