Question

q7. a physician orders 2.5 mg of an im injectable solution. only a vial of the solution with a dose strength of 2 mg/ml is available. what volume of the on - hand solution should be administered?

Explanation:

Step1: Use the formula \(V=\frac{D}{H}\times Q\)

Here, \(D = 2.5\) mg (desired dose), \(H=2\) mg/mL (dose - strength), and \(Q = 1\) mL (quantity per unit - dose strength, since the strength is given as \(mg/mL\)).

Step2: Substitute the values into the formula

\(V=\frac{2.5}{2}\times1\)
\(V = 1.25\) mL

Answer:

\(1.25\) mL
