I believe the answer is:
intern
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">medical resident</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for intern that I've seen before include "Imprison the young doctor without trial" , "Confine the hospital resident" , "put in jail" , "Lock up the hospital doctor" , "Hospital worker" .)
