Chapter 2, Problem 65a
Using conversion factors, solve each of the following clinical problems:
a. You have used 250 L of distilled water for a dialysis patient. How many gallons of water is that?
Verified step by step guidance1
Step 1: Identify the conversion factor between liters and gallons. The relationship is 1 gallon = 3.785 liters.
Step 2: Set up the conversion equation using the given volume in liters (250 L) and the conversion factor. The equation will be: \( \text{Volume in gallons} = \frac{\text{Volume in liters}}{\text{Conversion factor}} \).
Step 3: Substitute the values into the equation: \( \text{Volume in gallons} = \frac{250}{3.785} \).
Step 4: Perform the division to calculate the volume in gallons. Ensure proper unit cancellation during the calculation.
Step 5: Verify the result to ensure it makes sense in the context of the problem (e.g., the number of gallons should be smaller than the number of liters since gallons are larger units).

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Conversion Factors
Conversion factors are numerical ratios used to convert one unit of measurement to another. They are essential in solving problems that require changing units, such as converting liters to gallons. For example, knowing that 1 gallon is approximately 3.785 liters allows for straightforward calculations by multiplying or dividing the quantity by the appropriate conversion factor.

Volume Measurement Units
Volume measurement units, such as liters and gallons, are used to quantify the space that a substance occupies. Liters are commonly used in scientific contexts, while gallons are more prevalent in everyday use, especially in the United States. Understanding the relationship between these units is crucial for accurate conversions in clinical settings, such as calculating fluid intake for patients.

Clinical Application of Measurements
In clinical settings, accurate measurement and conversion of fluids are vital for patient care, particularly in treatments like dialysis. Knowing how to convert between different volume units ensures that healthcare providers can administer the correct amounts of fluids, which is essential for patient safety and treatment efficacy. This skill is particularly important when dealing with large volumes, such as the 250 liters mentioned in the problem.
