Nursing Metric Conversions Questions

Question 1 of 5

The metric prefix of Tera is abbreviated as T- and has a value of 10^12. What does Tera mean numerically?

Correct Answer: C

Rationale: The metric prefix Tera is abbreviated as T- and represents 10^12, which means 1 trillion. Tera is derived from the Greek word for "monster" or "giant." Therefore, the correct numerical value for Tera is 10^12. Choice A (10^6) is incorrect as it represents the metric prefix "Mega." Choice B (10^9) is incorrect as it represents the metric prefix "Giga." Choice D (10^3) is incorrect as it represents the metric prefix "Kilo."

Question 2 of 5

How many milliliters are in 1.5 liters?

Correct Answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter = 1000 milliliters. Therefore, 1.5 liters x 1000 = 1500 milliliters. So, the correct answer is B: 1,500 mL. A is incorrect as it is 10 times less than the correct answer. C is incorrect as it is 10 times less than the correct answer. D is incorrect as it is 100 times more than the correct answer.

Question 3 of 5

What is the base unit for mass in the metric system?

Correct Answer: B

Rationale: The correct answer is B: grams. Grams are the base unit for mass in the metric system. The metric system is based on powers of ten, making it easy to convert between units. Milligrams (A) are smaller units, kilograms (C) are larger units, and tons (D) are even larger units. Grams are the most commonly used unit for measuring everyday items and are the standard unit for mass in the metric system.

Question 4 of 5

What is 0.26 as a fraction in simplest form?

Correct Answer: A

Rationale: To convert 0.26 to a fraction, we can write it as 26/100 since 0.26 is equivalent to 26 hundredths. To simplify this fraction, we divide the numerator and denominator by their greatest common divisor, which is 2. Therefore, 26/100 simplifies to 13/50. This is the correct answer (A) in simplest form. Choice B (26/100) is the initial form of 0.26 but not in simplest form as it can be further simplified to 13/50. Choice C (26/1000) is incorrect as the decimal 0.26 is equivalent to 26/100, not 26/1000. Choice D (1/4) is not equivalent to 0.26.

Question 5 of 5

How many liters (L) are equal to 1 kiloliter?

Correct Answer: B

Rationale: The correct answer is B: 1,000 liters. The prefix "kilo-" represents 1,000 units. Therefore, 1 kiloliter is equal to 1,000 liters. Rationale: 1 kiloliter = 1,000 liters A: 100 liters - Incorrect, not equivalent to a kiloliter. C: 10 liters - Incorrect, too small to be a kiloliter. D: 10,000 liters - Incorrect, greater than the value of a kiloliter.
