Solution Steps

To find the rate at which the IV pump should be set, we need to determine how many milliliters per hour the solution should be delivered. We know the total volume to be infused is 100 mL and it needs to be infused over 30 minutes. First, convert the infusion time from minutes to hours. Then, divide the total volume by the time in hours to find the rate in mL/hr.

Step 1: Determine the Total Volume to be Infused

The total volume of the solution to be infused is given as 100 mL.

Step 2: Convert Infusion Time from Minutes to Hours

The infusion time is given as 30 minutes. To convert this to hours, use the conversion factor \( \frac{1 \text{ hour}}{60 \text{ minutes}} \): \[ \text{Infusion time in hours} = \frac{30 \text{ minutes}}{60} = 0.5 \text{ hours} \]

Step 3: Calculate the Infusion Rate in mL/hr

To find the infusion rate in mL/hr, divide the total volume by the infusion time in hours: \[ \text{Rate in mL/hr} = \frac{100 \text{ mL}}{0.5 \text{ hours}} = 200 \text{ mL/hr} \]

Final Answer

\(\boxed{200 \, \text{mL/hr}}\)

During World War I and throughout the 1920s, the Court was unforgiving of dissent and harshly ruled against unpopular political views and distributing materials critical of the American government During World War I, the American Civil Liberties Union (ACLU) was formed in order to defend the right of dissent, but it was not until the 1920s that it was able to successfully mobilize in defense of civil liberties. In the 1920s, the Supreme Court started overturning convictions of people for just expressing their point of view. During World War I, the Supreme Court oppressed free speech, but throughout the 1920s it reconsidered these rules and began to defend the Bill of Rights.
