Nursing Metric Conversions

1. Convert 3.75 liters to milliliters.

Correct answer: C

Rationale: To convert liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in 1 liter. Therefore, 3.75 liters x 1000 = 3750 milliliters. This means that option C, 3750 ml, is the correct conversion. Choices A, B, and D are incorrect because they do not reflect the correct conversion from liters to milliliters.

2. What unit is used to measure density in the metric system?

Correct answer: A

Rationale: Density is measured in grams per cubic meter (g/m³) in the metric system. This unit represents the amount of mass (in grams) per unit volume (cubic meter). Choice B, grams per liter (g/L), is incorrect as density is not typically measured in liters. Choice C, grams per cubic centimeter (g/cm³), is a common unit for density but not the standard SI unit. Choice D, grams per square meter (g/m²), is a unit for surface density, not volumetric density. Therefore, the correct unit for measuring density in the metric system is grams per cubic meter (g/m³).

3. What is the base unit for volume of a solid in the metric system?

Correct answer: A

Rationale: The correct answer is 'cubic meters' (A) which is the base unit for volume of a solid in the metric system. Volume is measured in cubic units (length × width × height) for solids. Choice B, 'meters cubed,' is not the standard way to express volume in the metric system. Choices C and D, 'grams' and 'centimeters,' are units of mass and length respectively, not volume.

4. What is 0.05 mcg in mg?

Correct answer: A

Rationale: To convert micrograms (mcg) to milligrams (mg), you need to divide by 1000. Therefore, 0.05 mcg equals 0.00005 mg. This conversion is crucial in the medical field to ensure accurate dosing. Choice B, 0.0005 mg, is incorrect as it represents 0.5 mcg. Choice C, 0.005 mg, is the equivalent of 5 mcg. Choice D, 0.05 mg, actually represents 50 mcg. It's important to pay attention to decimal placement and unit conversions to avoid medication errors.

5. How many ounces are in 2 quarts?

Correct answer: C

Rationale: To convert quarts to ounces, you need to know that 1 quart is equal to 32 ounces. Therefore, 2 quarts would be 2 x 32 = 64 ounces. The correct answer is not 16 ounces as stated in the original rationale. The correct answer is 64 ounces, which corresponds to 2 quarts. As a result, 'C: 16 ounces' is incorrect. Options A, B, and D are also incorrect as they do not reflect the accurate conversion from quarts to ounces.
