Nursing Metric Conversion Questions

Question 1 of 5

Convert 25 millimeters to centimeters.

Correct Answer: D

Rationale: To convert millimeters to centimeters, we divide by 10 since there are 10 millimeters in 1 centimeter. Therefore, 25 mm / 10 = 2.5 cm. The correct answer is D: 25 mm, as it represents the initial quantity to be converted. Choices A and B are incorrect as they do not follow the conversion factor. Choice C is incorrect as it represents the original unit rather than the converted unit.

Question 2 of 5

How many ounces are in 0.5 liters?

Correct Answer: A

Rationale: To convert liters to ounces, we need to know that 1 liter is approximately 33.814 ounces. Therefore, 0.5 liters is 0.5 x 33.814 = 16.907 ounces, which is rounded to 16.91 oz. Choice A is correct because it accurately represents the conversion. Choices B, C, and D are incorrect as they do not reflect the accurate conversion from liters to ounces.

Question 3 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.

Question 4 of 5

How many liters are in 750 milliliters?

Correct Answer: B

Rationale: To convert milliliters to liters, we divide by 1000 since there are 1000 milliliters in a liter. So, 750 milliliters ÷ 1000 = 0.75 liters. Therefore, the correct answer is B. Choice A is incorrect as it incorrectly moves the decimal point. Choices C and D are incorrect as they incorrectly add extra zeros and move the decimal point in the wrong direction.

Question 5 of 5

What is the result of multiplying 0.15 by 3?

Correct Answer: C

Rationale: To find the result of multiplying 0.15 by 3, we simply multiply the two numbers together. 0.15 * 3 = 0.45. This is because when you multiply a decimal by a whole number, you multiply the decimal part as usual and then place the decimal point in the product according to the total number of decimal places in the numbers being multiplied. In this case, 0.15 has two decimal places, and 3 is a whole number, so the product is 0.45. Choice A (0.05) is incorrect as it is the result of multiplying 0.15 by 0.33, not 3. Choice B (0.15) is incorrect as it is the original number being multiplied, not the result. Choice D (0.45) is incorrect as it is the same as the correct answer, but repeated in the choices, which usually does not happen in multiple-choice questions.
