According to this article, the answer's yes:
No record at Naval Historical of John Kerry's First Purple Hearthttp://www.insightmag.com/news/2004/04/27/Politics/Purple.Hearts.Three.And.Out-656749.shtml~snip~
According to Kerry's own description in Douglas Brinkley's Tour of Duty, the Dec. 2, 1968, mission behind what he has claimed to be his first Purple Heart was "a half-assed action that hardly qualified as combat." Indeed. Kerry was stationed with Coastal Division 14 at Cam Ranh Bay. At that time he piloted a small foam-filled boat, known as a Boston Whaler, with two enlisted men in the darkness of early morning. The intent, apparently, was to patrol an area that was known for contraband trafficking, but it was an undocumented mission. Upon approaching the objective point, the crew noticed a sampan crossing the river. As it pulled to shore, Kerry and his little team opened fire, destroying the boat and whatever its cargo might have been.
In the confusion, Kerry claims to have received a "stinging piece of heat" in the arm, the result of a tiny piece of shrapnel. He was not incapacitated and continued with regular swiftboat-patrol duty. William Shachte, who oversaw this ad hoc mission, was quoted by the Boston Globe as saying Kerry's injury, from whatever source, "was not a serious wound at all."
But Kerry met with his immediate superior officer, Lt.Cmdr. Grant Hibbard, the next morning and requested a Purple Heart for his wound. Hibbard recalls that Kerry had a "minor scratch" on his arm and was holding in his hand what appeared to be a fragment of a U.S. M-79 grenade, the shrapnel that had caused the wound. "They didn't receive enemy fire," Hibbard tells Insight. Since this was an essential requirement for the award, the commander rejected Kerry's request. Hibbard does not remember that Kerry received medical attention of any kind and confirms that no one else on the mission suffered any injuries.

PS there's a poll on that page: "Should Congress extend the Patriot Act?" When I voted, it was 70% "no."
