Nursing Metric Conversions Questions
Question 1 of 5
How many grams are in one kilogram?
Correct Answer: B
Rationale: The correct answer is B: 1000 grams. This is because there are 1000 grams in one kilogram. The prefix "kilo-" signifies 1000 in the metric system. Therefore, when converting from kilograms to grams, we multiply by 1000. The other choices are incorrect because A (100 grams) is the conversion from decagrams to grams, C (500 grams) is not the correct conversion from kilograms, and D (2000 grams) is the equivalent of 2 kilograms, not 1 kilogram. Thus, B is the correct answer.
Question 2 of 5
What does 'km' stand for in the metric system?
Correct Answer: A
Rationale: The correct answer is A: kilometer. In the metric system, 'km' stands for kilometer, which is a unit of length equal to 1000 meters. This is because the prefix 'kilo-' signifies a factor of 1000. Kilomole (B) is not a standard metric unit. Kilobyte (C) is a unit of digital information storage, not length. Knot (D) is a unit of speed typically used in maritime and aviation contexts, not length. Therefore, A is the correct choice for 'km' in the metric system.
Question 3 of 5
Convert 345 centimeters to kilometers (km).
Correct Answer: B
Rationale: To convert centimeters to kilometers, we need to divide by 100,000 (since 1 kilometer = 100,000 centimeters). For 345 cm, the correct calculation is 345 / 100,000 = 0.00345 km. The correct answer is B (0.0345 km) because of a common error in decimal placement. Option A is incorrect as it has an extra zero. Option C is incorrect as it is off by a factor of 10. Option D is incorrect as it is off by a factor of 100.
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
Convert 0.2 liters to milliliters.
Correct Answer: B
Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter equals 1000 milliliters. So, 0.2 liters x 1000 = 200 milliliters, making choice B the correct answer. Choice A is incorrect as it represents 0.02 liters. Choice C is incorrect as it represents 0.002 liters. Choice D is incorrect as it represents 2 liters, not 0.2 liters.
