Question

choose a method of calculation dosage and complete the following dosage calculation. order: 0.4 milligrams have: 2.0 milligrams per milliliter give: ________

Explanation:

Step1: Set up the formula

Use the formula \(V=\frac{D}{H}\times Q\), where \(D\) (desired dose) is \(0.4\) mg, \(H\) (dose on hand) is \(2.0\) mg/mL, and \(Q\) (quantity) is \(1\) mL.

Step2: Substitute the values

Substitute \(D = 0.4\), \(H=2.0\), and \(Q = 1\) into the formula: \(V=\frac{0.4}{2.0}\times1\).

Step3: Calculate the value

\(\frac{0.4}{2.0}=0.2\), so \(V = 0.2\) mL.

Answer:

\(0.2\) milliliters
