Question

nurse denise is calculating keilens dose of ibuprofen. available is a liquid preparation that contains 100 mg/5 ml. the label indicates to administer 10 mg/kg/dose. keilen weighs 27.5 lb. how many ml should denise tell ms. ralston to administer? (round the answer to the nearest tenth.) enter answer

Explanation:

Step1: Convert weight from lb to kg

Since \(1\ lb = 0.4536\ kg\), for a weight of \(27.5\ lb\), the weight in kg is \(27.5\times0.4536 = 12.474\ kg\).

Step2: Calculate the dose in mg

The dose is \(10\ mg/kg/dose\). So the dose in mg is \(10\times12.474=124.74\ mg\).

Step3: Calculate the volume in mL

The liquid preparation is \(100\ mg/5\ mL\). Let the volume be \(V\). Using the proportion \(\frac{100\ mg}{5\ mL}=\frac{124.74\ mg}{V}\). Cross - multiply gives \(100V = 124.74\times5\). Then \(V=\frac{124.74\times5}{100}=\frac{623.7}{100}=6.237\ mL\).

Answer:

\(6.2\ mL\)
