Answer:
3.16 mL
Explanation:
The patient weighs 130 lb.
Since the order is for 0.15mg of drug per kilogram of body weight, convert the weight of the patient to kg.
[tex]\begin{gathered} 2.2\;lbs=1\text{ kg} \\ 1\;lbs=\frac{1}{2.2}\text{ kg} \\ \implies139\text{ lb}=139\times\frac{1}{2.2}=63.1818\text{ kg} \end{gathered}[/tex]Next, determine the total mg of drug the patient requires.
[tex]\begin{gathered} \text{0.15mg of drug per kilogram of body weight.} \\ \text{Total mg of drug needed}=0.15\times63.1818=9.4772\;mg \end{gathered}[/tex]The drug label indicates the concentration to be 3mg/mL:
[tex]\begin{gathered} 9.4772\;mg\div\frac{3mg}{mL} \\ =\frac{9.4772\;mg\times mL}{3\;mg} \\ =3.16\text{ mL} \end{gathered}[/tex]You should administer 3.16 mL of the drug (correct to 2 decimal places).
