Metric Conversions for Nursing Questions
Question 1 of 5
How many milliliters are in 1 ounce?
Correct Answer: B
Rationale: To convert ounces to milliliters, we need to know that 1 ounce is approximately equal to 29.57 milliliters. Therefore, the closest option to this conversion is B: 30 ml. Choices A, C, and D are not correct as they do not match the accurate conversion rate. A (20 ml) is too low, C (40 ml) is too high, and D (50 ml) is also too high. Therefore, the correct answer is B (30 ml) as it is the closest approximation to the actual conversion rate of 1 ounce to milliliters.
Question 2 of 5
What is 0.5 x 200?
Correct Answer: A
Rationale: To solve 0.5 x 200, we multiply 0.5 by 200, which equals 100. This is because when we multiply a decimal by a whole number, we move the decimal point to the right the same number of places as the total number of decimal places in the factors. In this case, 0.5 has one decimal place, and 200 is a whole number. Therefore, the correct answer is A: 100. Choice B: 50 is incorrect because it results from multiplying 0.5 by 100 instead of 200. Choice C: 150 is incorrect as it is the result of multiplying 0.5 by 300. Choice D: 200 is incorrect because it is one of the factors in the multiplication operation, not the result of the operation.
Question 3 of 5
What is 0.5 liter in ounces?
Correct Answer: A
Rationale: To convert liters to ounces, we need to know that 1 liter is equal to 33.814 ounces. Therefore, 0.5 liter would be 0.5 * 33.814 = 16.907 ounces. Rounding to two decimal places, the correct answer is 16.91 oz (choice A). Choices B, C, and D are incorrect as they do not accurately represent the conversion of 0.5 liter to ounces.
Question 4 of 5
How many millimeters (mm) are in 3.45 meters?
Correct Answer: B
Rationale: The correct answer is B: 3,450 mm. To convert meters to millimeters, we know that 1 meter is equal to 1,000 millimeters. Therefore, to find how many millimeters are in 3.45 meters, we multiply 3.45 by 1,000, which equals 3,450 mm. Incorrect choices: A: 345 mm - Incorrect because it is the result of multiplying 3.45 by 100 (not 1,000). C: 345,000 mm - Incorrect as it is the result of incorrectly multiplying 3.45 by 100,000. D: 3.45 mm - Incorrect as it is the original amount in meters, not the converted amount in millimeters.
Question 5 of 5
How many centimeters are in one meter?
Correct Answer: B
Rationale: The correct answer is B: 100 cm. There are 100 centimeters in one meter because the metric system is based on units of 10. 1 meter is equivalent to 100 centimeters. Choice A is incorrect because 1/10 cm is not a valid conversion from meters to centimeters. Choice C is incorrect as 10 cm is the conversion from decimeters to centimeters, not meters. Choice D is incorrect because 1000 cm is the conversion from meters to millimeters, not centimeters. Therefore, the correct choice is B as it accurately reflects the conversion from meters to centimeters in the metric system.
