Nursing Metric Conversion

Correct Answer: B

Rationale: To convert milliliters to liters, we divide by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 3450 milliliters / 1000 = 3.45 liters. Choice B is correct. Choice A is incorrect as it is off by a factor of 10. Choice C is incorrect as it is off by a factor of 100. Choice D is incorrect as it is off by a factor of 1000.

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.

Correct Answer: A

Rationale: To express 0.07 as a fraction, we consider the decimal places. Since there are two decimal places in 0.07, we write it as 7/100. This simplifies to 7/100 as the correct fraction. Option A is correct as it represents 0.07 accurately. Options B, C, and D are incorrect as they do not match the decimal value of 0.07. B is 1/10, C is 1/20, and D is 1/50, which are not equivalent to 0.07.

Correct Answer: D

Rationale: To convert millimeters to centimeters, we divide by 10 since there are 10 millimeters in 1 centimeter. Therefore, 25 mm / 10 = 2.5 cm. The correct answer is D: 25 mm, as it represents the initial quantity to be converted. Choices A and B are incorrect as they do not follow the conversion factor. Choice C is incorrect as it represents the original unit rather than the converted unit.

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.
