Metric Conversions for Nursing Questions
Question 1 of 5
Convert 0.07 to a fraction.
Correct Answer: A
Rationale: To convert 0.07 to a fraction, we note that 0.07 = 7/100. The rationale is to move the decimal two places to the right to get the numerator and place it over 100 (10^2) to get the denominator. Option A (7/100) is correct. Option B (1/10) is incorrect because it represents 0.1, not 0.07. Option C (1/20) is incorrect as it represents 0.05. Option D (1/50) is incorrect as it represents 0.02.
Question 2 of 5
What is the equivalent of 0.3 mg in ml?
Correct Answer: A
Rationale: To convert mg to ml, we need to know the density of the substance. Assuming water density, 1 mg = 1 ml. Therefore, 0.3 mg is equivalent to 0.3 ml. Other choices are incorrect because they do not correspond to the correct conversion factor or are off by a factor of 10.
Question 3 of 5
How many quarts are equivalent to 2 liters?
Correct Answer: A
Rationale: The correct answer is A: 1.06 quarts. To convert liters to quarts, we use the conversion factor 1 liter = 1.05668821 quarts. Therefore, 2 liters would be approximately 2.11337642 quarts, which can be rounded to 1.06 quarts. The other choices are incorrect because B (0.5 quarts), C (2.1 quarts), and D (4 quarts) do not accurately represent the conversion of 2 liters to quarts based on the conversion factor.
Question 4 of 5
What is 0.04 g in mg?
Correct Answer: A
Rationale: To convert grams to milligrams, you need to multiply by 1000 since 1 g = 1000 mg. Therefore, 0.04 g * 1000 = 40 mg. Thus, the correct answer is A: 40 mg. Choice B is incorrect as it is 10 times more than the correct answer. Choice C is incorrect as it is 10 times less than the correct answer. Choice D is incorrect as it is 100 times less than the correct answer.
Question 5 of 5
How many milliliters are in 2 liters?
Correct Answer: C
Rationale: The correct answer is C: 2,000 mL. To convert liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in 1 liter. So, 2 liters x 1,000 mL = 2,000 mL. Explanation for Other Choices: A: 20 mL - This is incorrect as it is just 1% of 2 liters. B: 200 mL - This is also incorrect as it is 10% of 2 liters. D: 20,000 mL - This is incorrect as it is 10 times the correct answer, which is too large for 2 liters.
