calculate the ordered
medication for each of the following IV bags to
achieve the ordered concentration
Ordered: Add 30 mEq KCl per L of IV fluid.
On hand: 360 mL IV solution. On hand is KCl 2 mEq / mL
Add: ______mEq; ___ mL
Ordered: Add 20 mEq KCl per L of IV fluid.
On hand: 700 mL IV solution/ On hand is KCl 2 mEq / mL
Add: _______mEq; ___mL
To calculate the amount of KCl to add to each IV bag, we will use the following formula:
Amount of KCl to add = Ordered concentration * Volume of IV fluid
Let's calculate the amount of KCl to add for each scenario:
Scenario 1:
Ordered: Add 30 mEq KCl per L of IV fluid.
On hand: 360 mL IV solution. On hand is KCl 2 mEq / mL
Given that the ordered concentration is 30 mEq/L and the volume of IV solution is 360 mL, we can calculate the amount of KCl to add as follows:
Amount of KCl to add = 30 mEq/L * (360 mL/1000 mL)
= 10.8 mEq
Therefore, you need to add 10.8 mEq of KCl to the IV bag.
To calculate the volume of KCl to add, we need to convert the mEq to mL using the concentration provided (2 mEq/mL):
Volume of KCl to add = 10.8 mEq / 2 mEq/mL
= 5.4 mL
Therefore, you need to add 5.4 mL of KCl to the IV bag.
Scenario 2:
Ordered: Add 20 mEq KCl per L of IV fluid.
On hand: 700 mL IV solution. On hand is KCl 2 mEq / mL
Given that the ordered concentration is 20 mEq/L and the volume of IV solution is 700 mL, we can calculate the amount of KCl to add as follows:
Amount of KCl to add = 20 mEq/L * (700 mL/1000 mL)
= 14 mEq
Therefore, you need to add 14 mEq of KCl to the IV bag.
To calculate the volume of KCl to add, we need to convert the mEq to mL using the concentration provided (2 mEq/mL):
Volume of KCl to add = 14 mEq / 2 mEq/mL
= 7 mL
Therefore, you need to add 7 mL of KCl to the IV bag.
To calculate the ordered medication for each IV bag, we need to determine the amount of KCl to add in milliequivalents (mEq) and milliliters (mL).
For the first IV bag:
Ordered: Add 30 mEq KCl per L of IV fluid.
On hand: 360 mL IV solution. The concentration is 2 mEq/mL.
Step 1: Convert the volume of IV solution from mL to L.
360 mL = 360 mL/1000 = 0.36 L
Step 2: Calculate the amount of KCl to add in mEq.
Since the ordered concentration is 30 mEq per liter of IV fluid, we can calculate it as follows:
30 mEq/L * 0.36 L = 10.8 mEq
Step 3: Calculate the amount of KCl to add in mL.
To find the volume (mL) of solution at a concentration of 2 mEq/mL that contains 10.8 mEq, divide 10.8 mEq by the concentration:
10.8 mEq / 2 mEq/mL = 5.4 mL
Therefore, for the first IV bag, you would need to add 10.8 mEq and 5.4 mL of KCl.
Now let's move on to the second IV bag:
Ordered: Add 20 mEq KCl per L of IV fluid.
On hand: 700 mL IV solution. The concentration is 2 mEq/mL.
Step 1: Convert the volume of IV solution from mL to L.
700 mL = 700 mL/1000 = 0.7 L
Step 2: Calculate the amount of KCl to add in mEq.
Since the ordered concentration is 20 mEq per liter of IV fluid, we can calculate it as follows:
20 mEq/L * 0.7 L = 14 mEq
Step 3: Calculate the amount of KCl to add in mL.
To find the volume (mL) of solution at a concentration of 2 mEq/mL that contains 14 mEq, divide 14 mEq by the concentration:
14 mEq / 2 mEq/mL = 7 mL
Therefore, for the second IV bag, you would need to add 14 mEq and 7 mL of KCl.
