Nursing Metric Conversion Questions
Question 1 of 5
What is 0.05 mcg in mg?
Correct Answer: A
Rationale: To convert micrograms (mcg) to milligrams (mg), we need to remember that 1 mcg is equal to 0.001 mg. Therefore, to convert 0.05 mcg to mg, we multiply 0.05 by 0.001 which gives us 0.00005 mg. This makes choice A the correct answer. Choices B, C, and D are incorrect because they do not correctly convert micrograms to milligrams based on the conversion factor of 0.001 mg per mcg.
Question 2 of 5
What is 0.6 liters converted to milliliters?
Correct Answer: A
Rationale: To convert liters to milliliters, we know that 1 liter is equal to 1000 milliliters. Therefore, 0.6 liters would be equal to 0.6 x 1000 = 600 milliliters. This makes choice A (600 ml) the correct answer. Choices B, C, and D are incorrect because they do not follow the correct conversion factor of 1 liter to 1000 milliliters. Choice B (60 ml) is ten times less than the correct answer, choice C (6 ml) is one hundred times less, and choice D (0.6 ml) is one thousand times less than the correct conversion.
Question 3 of 5
How many feet are in one mile?
Correct Answer: B
Rationale: The correct answer is B: 5280 feet in one mile. This is because 1 mile is equivalent to 5280 feet. This conversion is a standard unit of measurement in the Imperial system. Choice A, 5000 feet, is too low and does not accurately represent the length of a mile. Choice C, 5300 feet, and choice D, 5500 feet, are both higher than the actual value of 5280 feet, making them incorrect. To convert miles to feet, we multiply by the conversion factor of 5280.
Question 4 of 5
What is 0.2 mg converted to mcg?
Correct Answer: A
Rationale: To convert 0.2 mg to mcg, we need to remember that 1 mg is equal to 1000 mcg. So, to convert 0.2 mg to mcg, we multiply 0.2 by 1000, which gives us 200 mcg. Therefore, the correct answer is A: 200 mcg. Incorrect answers: B: 20 mcg - Incorrect because it does not account for the correct conversion factor of 1000 mcg per 1 mg. C: 2000 mcg - Incorrect as it incorrectly multiplies 0.2 mg by 1000 twice. D: 2 mcg - Incorrect as it does not consider the correct conversion of 0.2 mg to mcg.
Question 5 of 5
How many milliliters are in a tablespoon?
Correct Answer: B
Rationale: The correct answer is B: 15 ml. A standard tablespoon is equivalent to 15 ml. This is a standard measurement in culinary and pharmaceutical fields. A tablespoon is commonly used for measuring liquid ingredients and medications. Choice A (10 ml) and Choice D (20 ml) are incorrect as they do not correspond to the standard measurement of a tablespoon. Choice C (5 ml) is also incorrect as it is too low to be the equivalent of a tablespoon. Therefore, B is the correct answer.
