Nursing Metric Conversion Questions
Question 1 of 5
What is 1500 milliliters in liters?
Correct Answer: A
Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in 1 liter. Therefore, 1500 milliliters divided by 1000 equals 1.5 liters. Choice A (1.5 liters) is correct because it accurately represents the conversion. Choices B, C, and D are incorrect because they do not follow the correct conversion factor of dividing by 1000. Choice B (0.15 liters) is one decimal place off, choice C (15 liters) is an order of magnitude too high, and choice D (0.015 liters) is two decimal places off.
Question 2 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 3 of 5
Which conversion is accurate?
Correct Answer: C
Rationale: The correct answer is C because 1 liter is equivalent to 1.057 quarts. To convert liters to quarts, we know that 1 liter is approximately equal to 1.057 quarts. This conversion is accurate because it reflects the actual conversion factor between liters and quarts. A: 1 inch = 2.54 cm, not 2.5 cm. B: 1 meter = 39.37 inches, not an incorrect conversion but not the most accurate one. D: 1 gram = 1000 milligrams, not 100 milligrams. In summary, choices A, B, and D are incorrect due to inaccurate conversion factors, whereas choice C is correct as it provides the accurate conversion between liters and quarts.
Question 4 of 5
What is 0.175 mg in mcg?
Correct Answer: C
Rationale: To convert mg to mcg, you multiply by 1000 since 1 mg = 1000 mcg. So, 0.175 mg x 1000 = 175 mcg. Therefore, the correct answer is C: 1750 mcg. Choices A, B, and D are incorrect because they do not correctly convert milligrams to micrograms.
Question 5 of 5
What does 'mm' stand for in the metric system?
Correct Answer: A
Rationale: The correct answer is A: millimeter. In the metric system, 'mm' stands for millimeter, which is a unit of length equal to one thousandth of a meter. This is the correct answer because "milli-" is a prefix in the metric system that denotes one thousandth. Megabyte (B) is a unit of digital information storage, not length. Millipede (C) refers to a type of arthropod, not a unit of measurement. Metered (D) is not a recognized unit in the metric system for length.
