Question

solve the following parenteral dosage problem.
the physician has ordered phenylephrine 2.7 milligrams sub - q for the client. the drug label on the vial reads 8 milligrams per milliliter.
how many milliliters should be given?
milliliter(s)
(simplify your answer. type an integer or decimal rounded to the nearest hundredth as needed.)

Explanation:

Step1: Identify the formula

Use the formula \(V=\frac{D}{H}\times Q\), where \(D\) (desired dose) = \(2.7\) mg, \(H\) (dose on - hand) = \(8\) mg/mL, and \(Q\) (quantity) = \(1\) mL.

Step2: Substitute the values into the formula

\(V=\frac{2.7}{8}\times1\)

Step3: Calculate the value

\(V = 2.7\div8=0.3375\approx0.34\) (rounded to the nearest hundredth)

Answer:

\(0.34\)
