About Nurse Clark[]
In "Margaret's Marriage", Clark is one of the nurses attending Margaret's bridal shower, together with Nurses Able (Judy Farrell), Baker (Patricia Stevens), Lieutenant Kellye Yamato (Kellye Nakahara) and an unnamed, uncredited nurse played by Gwen Farrell. During the shower, Clark gives Margaret a drink, saying it is just a mixture of poison and fruit juice. Margaret drinks it and says, "Too much fruit juice!" She attends the wedding ceremony the next day and then joins the rest of the MASH personnel performing triage in her dress uniform when the wedding is interrupted by the arrival of wounded.
Lieutenant Clark is not to be confused with Lieutenant Debbie Clark, a different nurse who comes from the 8063rd MASH and who becomes Klinger's love interest in Season 7 episode "Ain't Love Grand".
