Nursing Metric Conversion Questions
Question 1 of 5
What is 0.5 liters to milliliters?
Correct Answer: A
Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter equals 1000 milliliters. So, 0.5 liters * 1000 = 500 ml. Therefore, the correct answer is A: 500 ml. Choice B (50 ml) is incorrect as it is 10 times less than the correct answer. Choice C (5 ml) is incorrect as it is 100 times less, and choice D (0.5 ml) is incorrect as it is the original volume in milliliters, not the conversion from liters.
Question 2 of 5
Is 0.25 mg equal to 250 mcg?
Correct Answer: A
Rationale: Step 1: Convert 0.25 mg to mcg: 0.25 mg * 1000 mcg/mg = 250 mcg Step 2: Compare the converted value (250 mcg) to 250 mcg. Step 3: Since the converted value matches 250 mcg, the statement "0.25 mg is equal to 250 mcg" is TRUE. Summary: - Option B (FALSE) is incorrect because the conversion shows they are equal. - Option C (Sometimes) doesn't apply as the conversion is a precise equivalence. - Option D (None of the above) is incorrect as option A is true based on the conversion.
Question 3 of 5
How many milliliters are in 1 liter?
Correct Answer: C
Rationale: The correct answer is C: 1,000 mL. This is because there are 1,000 milliliters in 1 liter. This conversion is based on the metric system, where the prefix "milli-" represents one-thousandth of the base unit. In this case, the base unit is the liter. To convert from liters to milliliters, you multiply the number of liters by 1,000 since there are 1,000 milliliters in one liter. Therefore, 1 liter is equal to 1,000 milliliters. Choices A, B, and D are incorrect because they do not accurately represent the conversion factor between liters and milliliters.
Question 4 of 5
What is the term for the amount of space an object occupies?
Correct Answer: B
Rationale: The correct answer is B: volume. Volume refers to the amount of space an object occupies in three dimensions. It is calculated by multiplying the length, width, and height of an object. Mass (A) is the amount of matter in an object, density (C) is the mass per unit volume, and area (D) is the measurement of the surface of an object in two dimensions. Therefore, volume is the most appropriate term for describing the amount of space an object occupies.
Question 5 of 5
What is 0.5 liters in milliliters?
Correct Answer: B
Rationale: To convert from liters to milliliters, you multiply by 1000 since there are 1000 milliliters in 1 liter. So, 0.5 liters x 1000 = 500 ml. Therefore, the correct answer is B. Choice A is incorrect because 0.5 liters is not equal to 50 ml. Choice C is incorrect because 0.5 liters is not equal to 5 ml. Choice D is incorrect because 0.5 liters is not equal to 0.5 ml.
