1.

### Ordered: 500 mg ampicillin in 100mL NS to infuse over 30 minutes. What is the flow rate per hour?

Explanation:
To calculate the flow rate per hour, we need to use the following formula:
Flow rate (mL/hour) = Total volume (mL) / Time (hours)
Here's how to apply it to this situation:

Total volume: We have 100 mL of normal saline (NS) solution.
Time: The solution needs to be infused over 30 minutes, which is 30 minutes / 60 minutes/hour = 0.5 hours.

Now, plug these values into the formula:
Flow rate (mL/hour) = 100 mL / 0.5 hours = 200 mL/hour
Therefore, the flow rate per hour is 200 mL.
So, the correct answer is 200 mL.
2.

### Ordered: 500 mL 5% Dextrose 0.45% NS over 3 hours. Find the flow rate per hour.

Explanation:
Let's calculate the flow rate per hour for the given order:Total volume: We have 500 mL of the solution to infuse.Time: The solution needs to be infused over 3 hours.Now, using the formula:Flow rate (mL/hour) = Total volume (mL) / Time (hours)Flow rate = 500 mL / 3 hours = 166.67 mL/hour (rounded to two decimal places)Therefore, the flow rate per hour is 167 mL. So, the correct answer is 167 mL.
3.

### Ordered: 1000 mL LR over 6 hours.  Find the flow rate in mL per hour.

Explanation:
The correct flow rate for 1000 mL LR over 6 hours is 167 mL per hour. Here's the calculation:Total volume: We have 1000 mL of LR solution.Time: The solution needs to be infused over 6 hours.Now, applying the formula:Flow rate (mL/hour) = Total volume (mL) / Time (hours)Flow rate = 1000 mL / 6 hours = 166.67 mL/hour (rounded to two decimal places)Therefore, the flow rate is 167 mL per hour, matching option B.
4.

### Find the flow rate in mL per hour. 300 mL NS over 2 H.

Explanation:
The flow rate for 300mL NS over 2 hours is 150 mL per hour.Here's the calculation:Total volume: We have 300 mL of NS solution.Time: The solution needs to be infused over 2 hours.Now, applying the formula:Flow rate (mL/hour) = Total volume (mL) / Time (hours)Flow rate = 300 mL / 2 hours = 150 mL/hourTherefore, the correct answer is 150 mL.
5.

### Find the flow rate in mL per hour. 3000 mL 0.45% over 24 H.

Explanation:
3000 mL / 24 H = 125 mL per hour
6.

### Find the flow rate in mL per hour. 1500 mL RL over 12 hours.

Explanation:
To find the flow rate for 1500 mL RL over 12 hours, we need to use the formula:Flow rate (mL/hour) = Total volume (mL) / Time (hours)Total volume: We have 1500 mL of RL solution.Time: The solution needs to be infused over 12 hours.Now, plugging these values into the formula:Flow rate = 1500 mL / 12 hours = 125 mL/hourTherefore, the flow rate in mL per hour is 125. So, the correct answer is C. 125.Remember, accurate medication administration relies on precise calculations. Always be sure to double-check your work and ensure appropriate rounding.
7.

### Find the flow rate in mL per hour. 40 mEq KCL in 100 mL NS over 45 minutes.

Explanation:
To calculate the flow rate in milliliters per hour (mL/h) for an IV infusion, you can use the following formula:
Flow Rate (mL/h) = (Volume to Infuse in mL) / Time in hours
Given: Volume to infuse = 100 mL
Time = 45 minutes, 1 hour = 60 minutes, so 45 minutes = 45/60 hours = 0.75 hours
Flow Rate = 100 mL / 0.75 hours = 133.33 mL/h
So, the flow rate for the IV infusion of 40 mEq of KCl in 100 mL of NS over 45 minutes is approximately 133.33 milliliters per hour.
8.

### Find the flow rate in mL per hour. 1000 mL NS over 12 hours.

Explanation:
The flow rate for 1000 mL of Normal Saline (NS) over 12 hours is 83 mL per hour. Here's the calculation:Total volume: We have 1000 mL of NS solution.Time: The solution needs to be infused over 12 hours.Using the formula:Flow rate (mL/hour) = Total volume (mL) / Time (hours)Flow rate = 1000 mL / 12 hours = 83.33 mL/hour (rounded to two decimal places)Therefore, the correct answer is A. 83.
9.

### Find the flow rate in mL per hour. 20 mEq KCL in 50 mL NS over 30 minutes.

Explanation:
The flow rate can be calculated by dividing the volume of the solution (50 mL) by the time it takes to infuse (30 minutes). The flow rate in mL per hour can be obtained by multiplying the result by 60 (to convert minutes to hours). Therefore, the flow rate in mL per hour for this solution is 100.
