Nursing Metric Conversions Questions

Question 1 of 5

What is 0.16 as a fraction?

Correct Answer: C

Rationale: To convert 0.16 to a fraction, we consider the decimal places. Since 0.16 has 2 decimal places, we write it as 16/100. Simplifying by dividing both numerator and denominator by 4, we get 4/25. Therefore, the correct answer is C. Option A is incorrect as it does not simplify to the simplest form. Option B is incorrect as it has an additional zero in the denominator. Option D is incorrect as it simplifies to 2/25, not 4/25.

Question 2 of 5

What does 'm' stand for in the metric system?

Correct Answer: A

Rationale: The correct answer is A: meter. In the metric system, 'm' stands for meter, which is the base unit of length. Mole (B) is a unit of amount of substance, milli (C) represents a prefix meaning one-thousandth, and micro (D) represents a prefix meaning one-millionth. Therefore, A is the correct choice as it directly corresponds to the unit of length in the metric system.

Question 3 of 5

How many ounces are in 2 quarts?

Correct Answer: C

Rationale: To convert from quarts to ounces, you need to know that 1 quart is equal to 32 ounces. Therefore, 2 quarts would be 2 * 32 = 64 ounces. The correct answer is C (16 ounces) because it is the only option that correctly states the conversion from quarts to ounces. Option A (8 ounces) is incorrect as it is half of the correct answer. Option B (32 ounces) is incorrect as it represents the amount in 1 quart, not 2 quarts. Option D (64 ounces) is incorrect as it corresponds to the total number of ounces in 2 quarts, not the conversion from quarts to ounces.

Question 4 of 5

What is the expression 1 in. = 2.54 cm properly called?

Correct Answer: D

Rationale: The correct answer is D: Exact Equivalent. This term refers to a precise conversion between two different units of measurement without any approximation. In this case, 1 inch is exactly equal to 2.54 centimeters, making it an exact equivalent. A: Law of Conservation of Units - This choice is incorrect because it does not refer to the specific term used for the conversion between inches and centimeters. B: International Yard - This choice is incorrect as it does not accurately describe the relationship between inches and centimeters. C: Standard Conversion Factor - This choice is incorrect because it is a general term and does not specifically address the exact relationship between inches and centimeters.

Question 5 of 5

How many milligrams are in 2 grams?

Correct Answer: B

Rationale: To convert grams to milligrams, you need to multiply by 1,000 since there are 1,000 milligrams in 1 gram. So, 2 grams x 1,000 = 2,000 mg. Therefore, the correct answer is B. A: 200 mg - This is incorrect as it doesn't account for the conversion factor from grams to milligrams. C: 20 mg - This is incorrect as it is 100 times less than the correct conversion. D: 20,000 mg - This is incorrect as it is 10 times greater than the correct conversion.
