I am trying to apply the answer to this question to the overloaded exam-randomizechoices oneparchoices environment; I want oneparchoices to spread out evenly with respect to the available horizontal space. However, when I attempt this, the formatting behaves unexpectedly. I believe this part of the exam-randomizechoices documentation might be essential to figuring this out. I'm not experienced working with latex on a technical level. Also, are there any other ways to achieve the same effect?
\documentclass[11pt]{exam}
\usepackage[margin=1in]{geometry}
\usepackage{xpatch}
\xpatchcmd{\oneparchoices}{\penalty -50\hskip 1em plus 1em\relax}{\hfill}{}{}% must be altered before loading exam-randomizechoices
\usepackage[overload]{exam-randomizechoices}
\setrandomizerseed{314}

\begin{document}
\noindent All questions should have evenly spaced multiple choice answers that take up all horizontal spacing.
\begin{questions}
\question
vanilla oneparchoices (works fine):\par
\begin{oneparchoices}[norandomize]
\CorrectChoice First
\choice Second
\choice Third
\choice Fourth
\end{oneparchoices}
\question
exam-randomizechoices oneparchoices (unexpected behavior):\par
\begin{oneparchoices}
\CorrectChoice First
\choice Second
\choice Third
\choice Fourth
\end{oneparchoices}
\end{questions}
\end{document}
\xpatchcmdafter loading the exam-randomizechoices package and nothing happens. There is likely another way to do it, but I cannot figure it out at my experience level.
