Narrative:

I was assigned controller in charge for the day watch. I was relieved from the radar sector by a low time controller who had been on vacation for over 2 weeks and only back to work for 3 days. The controller indicated they might want help; so after a brief biological break; I came back and plugged in to assist. The controller had created a complex traffic situation involving two other aircraft; of which one did not acquire a data block. I was assisting the controller with vectoring a dash 8 to the localizer from the west and did not notice the C182 less than 3 miles east of the final. The dash 8 was descending from 5;000 to 3;000 cleared for the ILS runway 16R; while the C182 was level on the opposite downwind at 4;000; but inside 3 miles from the final. I told the controller to turn the C182 to a heading of 030 for traffic; the controller gave the instruction; but the pilot read back heading 360. The controller reiterated the 030 heading; but did not emphasize 'immediately' or call traffic. Leading factors; in my opinion; the controller did not take the hand off on the dash 8 from the center in a timely manner; thus creating a difficult situation in vectoring the aircraft to final. Additionally; the controller released an aircraft from a satellite airport to do practice approaches at a major airport a bad time and without appropriate positive control. The controller didn't recognize the limited data block and effectively control the aircraft; therefore becoming an eminent situation with another IFR aircraft head on at 4;000. This created a distraction for me; as I had to give additional instruction to the controller to get them to react to that situation. Additionally; I was responsible for the operation and had to answer the telephone while assisting the controller. I informed the controller that they might have had a deal. The controller appeared very flustered and was having difficulty formulating control instructions. I immediately saw the distress and relieved the controller. Recommendation; next time I'll work it myself. This controller was certified right before going on an extended vacation; which in my opinion; might not have been appropriate.
