You can use a standard TikZ node and its label key:

\documentclass{article}
\usepackage{circuitikz}

\begin{document}

\begin{circuitikz}
\draw 
  (0,0) 
    node[label={[font=\footnotesize]above:Node}] {}
  to[R,*-*] (2,0) 
    node[label={[font=\footnotesize]-30:$1$},label={[font=\footnotesize]150:$2$}] {}
  to[R,*-*] (4,0) 
    node[label={[font=\footnotesize]above:$3$}] {}
;
\end{circuitikz}

\end{document}
