Question

suppose a patient is mistakenly given 600 ml of 150 mm kcl instead of isotonic saline (nacl) in an intravenous (iv) infusion. how many millimoles of k are in 600 ml of this solution?

Answer 1

There are 90 millimoles of potassium (K) in 600 mL of a 150 mM KCl solution, calculated by multiplying the volume in liters (0.600 L) by the concentration (150 mmol/L).

Step-by-step explanation:

To calculate how many millimoles of K are in 600 mL of a 150 mM KCl solution, we use the following steps:

1. Convert the volume from mL to L, knowing that 1000 mL equals 1 L. So, for 600 mL we have 0.600 L.
2. Use the concentration of the KCl solution to find the number of millimoles in one liter, which is 150 mmol/L.
3. Multiply the volume of the solution in liters by the concentration in mmol/L to obtain the number of millimoles of K: 0.600 L × 150 mmol/L = 90 mmol.

Therefore, there are 90 millimoles of potassium (K) in 600 mL of this 150 mM KCl solution.
