Question

q6. 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: Identify the formula

Use the formula \(V=\frac{D}{H}\times Q\), where \(D\) (desired dose) = \(2.5\) mg, \(H\) (dose on - hand) = \(2\) mg/mL, and \(Q\) (quantity of the on - hand solution per unit dose). Here \(Q = 1\) mL (since the strength is given as \(2\) mg/mL).

Step2: Substitute the values into the formula

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