Nursing Metric Conversions Questions
Question 1 of 5
Convert 0.5 centimeters to millimeters.
Correct Answer: A
Rationale: To convert centimeters to millimeters, you multiply by 10 since 1 cm = 10 mm. Therefore, 0.5 cm * 10 mm/cm = 5 mm. Choice A (5 mm) is correct. Choice B (0.5 mm) is incorrect as it represents the original value in millimeters. Choice C (50 mm) is incorrect as it is 10 times greater than the correct value. Choice D (0.05 mm) is incorrect as it is 100 times smaller than the correct value.
Question 2 of 5
What is 0.2 rounded to the nearest tenth?
Correct Answer: B
Rationale: The number 0.2 rounded to the nearest tenth means rounding to one decimal place. Since the digit after the tenths place is 0, we keep the tenths place as it is. Therefore, the correct answer is B: 0.2. A: 0.1 - Incorrect, this is rounding down to the nearest tenth. C: 0.3 - Incorrect, this is rounding up to the nearest tenth. D: 0.25 - Incorrect, this is rounding to the nearest hundredth, not tenth.
Question 3 of 5
How many ounces are in 2 quarts?
Correct Answer: C
Rationale: To convert from quarts to ounces, you need to know that 1 quart is equal to 32 ounces. Therefore, 2 quarts would be 2 * 32 = 64 ounces. The correct answer is C (16 ounces) because it is the only option that correctly states the conversion from quarts to ounces. Option A (8 ounces) is incorrect as it is half of the correct answer. Option B (32 ounces) is incorrect as it represents the amount in 1 quart, not 2 quarts. Option D (64 ounces) is incorrect as it corresponds to the total number of ounces in 2 quarts, not the conversion from quarts to ounces.
Question 4 of 5
What is 0.025 mg converted to micrograms?
Correct Answer: A
Rationale: To convert mg to mcg, you multiply by 1000 since 1 mg = 1000 mcg. Therefore, 0.025 mg * 1000 = 25 mcg, which is choice A. Choice B is incorrect as it incorrectly multiplies by 10 instead of 1000. Choice C is incorrect as it incorrectly divides by 10. Choice D is incorrect as it incorrectly divides by 100 instead of multiplying by 1000.
Question 5 of 5
