Question

a dose of 30 meq kcl has been added to 1 liter of ns. what drip rate would provide a patient with 2 meq kcl per hour?

Explanation:

Step1: Set up proportion

Let $x$ be the volume (in liters) to be infused per hour. We know that there are 30 meq of KCl in 1 liter of solution. So the proportion is $\frac{30\ meq}{1\ L}=\frac{2\ meq}{x\ L}$.

Step2: Cross - multiply

Cross - multiplying gives us $30x = 2\times1$.

Step3: Solve for $x$

Dividing both sides by 30, we get $x=\frac{2}{30}=\frac{1}{15}$ liters per hour. Since 1 liter = 1000 mL, $x=\frac{1}{15}\times1000=\frac{1000}{15}\approx66.67$ mL per hour.

Answer:

Approximately 66.67 mL per hour
