Metric Conversions for Nursing Questions

Question 1 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 2 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 3 of 5

What is the equivalent of 500 milliliters in liters?

Correct Answer: B

Rationale: To convert milliliters to liters, we need to divide by 1000 since 1 liter is equal to 1000 milliliters. So, 500 milliliters divided by 1000 equals 0.5 liters, making choice B the correct answer. Choice A (0.05 liters) is incorrect as it is one decimal place off. Choice C (5 liters) and choice D (50 liters) are both significantly higher values and do not align with the conversion factor from milliliters to liters.

Question 4 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.

Question 5 of 5

How many mcg are there in 0.2 mg?

Correct Answer: B

Rationale: To convert milligrams (mg) to micrograms (mcg), you need to multiply by 1000. Therefore, to find how many mcg are in 0.2 mg, you would multiply 0.2 by 1000, which equals 200 mcg. Choice B is correct. Choices A, C, and D are incorrect as they do not accurately convert 0.2 mg to mcg. Choice A is too low, choice C is too high, and choice D is too low.
