A patient is receiving an infusion from a manual / gravity set. The infusion rates at 0930 and 1030 are provided in the table below. 

Time	Infusion Rate
0930	75 gtt/min
1030	51 gtt/min
Use the information above to address the following:

The absolute change in rates from 0930 to 1030 is  
Number
 gtt/min.  (No negative sign needed)
From 0930 to 1030, the infusion rate decreased by  
Number
 % (i.e., calculate the percent change)

Let's first calculate the **absolute change** in the infusion rates.

- Infusion rate at 0930: 75 gtt/min
- Infusion rate at 1030: 51 gtt/min

The absolute change is the difference between these two rates:

\[
\text{Absolute Change} = 75 - 51 = 24 \, \text{gtt/min}
\]

So, the absolute change in rates from 0930 to 1030 is **24 gtt/min**.

Next, let's calculate the **percent decrease** in the infusion rate.

The formula for percent change is:

\[
\text{Percent Change} = \frac{\text{Absolute Change}}{\text{Initial Value}} \times 100
\]

Here, the absolute change is \( 24 \, \text{gtt/min} \) and the initial value (rate at 0930) is \( 75 \, \text{gtt/min} \).

\[
\text{Percent Change} = \frac{24}{75} \times 100 = 32\%
\]

Thus, the infusion rate decreased by **32%** from 0930 to 1030.

Here are 5 related questions for further exploration:
1. How would the infusion rate change if it decreased by 50% instead?
2. How do you calculate the time it would take to completely stop the infusion if the rate kept decreasing by 24 gtt/min every hour?
3. What are the common reasons for such a decrease in infusion rate over time?
4. How can adjusting the height of a gravity infusion set impact the infusion rate?
5. How would you calculate the new infusion rate if it decreased by an additional 10 gtt/min in the next hour?

**Tip:** Percent change is always calculated based on the initial value, so always take care when identifying the starting point in your problems.
