''When something has gone wrong,'' she went on, ''all have a personal need to see their piece of it. It is a natural reaction. They say to themselves: 'I know I did it right.' So it is natural that they are all there. They need to know that they did it right.'' The nurses said there is a definite feeling that they are involved in a team effort in the care of Dr. [Barney B. Clark]. ''When we are not working with him, we still in a way are working with him,'' Miss Pierce said. ''We keep up with what's going on. He's kind of our baby. No one keeps track of how many days they have taken care of him.'' ''In Dr. Clark's case you must explain what 'fine' means,'' she said. ''He wants to know specifically what are you doing and why. So we tell him 'Your lungs are better, your chest X-ray looks great, and we're giving you this medicine for this reason.' Then Dr. Clark says 'O.K.' and goes on to something else. You can't talk in platitudes with him.''

Dr. Barney B. Clark's nurses gave him an early Christmas present today - a vanilla milkshake. It was the 61-year-old retired dentist's first soft food by mouth since his operation on Dec. 2, when he was given an artificial heart, said John Dwan, a spokesman for the University of Utah Medical Center. ''Things appear to be going very well, and the mood is very relaxed,'' Mr. Dwan said at a news conference. He also said that Dr. William C. DeVries, the surgeon who heads the team caring for Dr. Clark, was ''pleased with the progress'' of his patient, and added, ''He is a little stronger and very stable.''

''What we have seen in the last two or three days is what we should phrase as a return to normalcy, both on the part of Dr. [Barney B. Clark], his family and the hospital staff,'' Mr. [John Dwan] said. He said he could recall as many as 11 doctors in Dr. Clark's room at one time in the hectic days after the artificial heart was implanted Dec. 2. But now, Mr. Dwan said, Dr. Clark may be seen ''sitting in a chair looking out the window,'' with a nurse sitting outside his room at a desk doing paper work and with no one else around. As for the walking, he said, Dr. Clark ''stands and sort of shuffles around and sits down in the chair - he's not striding down the hall.''

The artificial heart recipient cannot talk because he is connected to an artificial respirator. But he gestured for Dr. [Willem J. Kolff] to come over to his bedside and mouthed the words, ''Don't quit,'' indicating he believes that Dr. Kolff and others must not abandon their efforts to perfect permanent artificial hearts. ''Dr. [Barney B. Clark] is always one to do more,'' Mr. [John Durkin] said. The exercises have not been limited by the two tubes that enter the left side of Dr. Clark's abdomen and that convey the air that makes his artificial heart beat

''After the time that we broke that valve we have not been going that high in pumping,'' Dr. [William C. DeVries] said in his first public appearance since Dec. 2. ''Maybe we should not have been pumping as vigorously as we were.'' Paying a Price for Speed One price, he said, is that ''we may end up putting an undue stress on the valve struts.'' ''In our zeal to increase the cardiac output we cannot lose sight that overpumping is dangerous, too,'' Dr. DeVries said. ''We are trying to regulate him so it won't happen again.'' Although Dr. DeVries called the research aspects of the experiment on Dr. [Barney B. Clark] ''an extreme success,'' he emphasized that the 61-yearold retired dentist ''is still a very, very sick man.'' ''He's only halfway through a marathon,'' he added

At a news conference last week, Dr. Peterson described himself as a ''frustrated medical teacher'' who viewed the artificial heart story as an opportunity to educate the public about medicine. He has earned high marks from reporters and colleagues for his ability to find cogent analogies and simple terms to describe complicated medical problems, as well as to say ''I don't know'' when stumped. For example, in answering questions after Dr. [Barney B. Clark] suffered seizures Dec. 7, Dr. Peterson had to deal with complexities of biochemistry and the possibility that the seizures had been brought on when too much of some vital substance had been washed from Dr. Clark's body by speeding up his heart and giving him diuretics. Dr. Peterson described this possibility as a ''leaching process.''

''His blood pressure and all cardiovascular systems were very stable when sitting and in particular his oxygen saturation was even better sitting than it was lying,'' Dr. [Chase N. Peterson] said, referring to a blood gas measurement. ''We would expect that because it helps the lungs to aerate better in that position.'' A Cumbersome Procedure ''But in the fourth quarter, Dr. [Barney B. Clark] became tired just like B.Y.U. did,'' Dr. Peterson said with a smile. Dr. Clark also sat up and dangled his feet over the side of the bed with the aid of staff members at the university's medical center. At no point so far has he stood on his own. Today, although more optimistic about Dr. Clark's condition, Dr. Peterson stressed: ''Since we don't know what's going on in this man, like all patients, tomorrow there could be some catastrophe and we will have a very different story.''

When the dials controlling the rate of the artificial heart were changed, Dr. [Barney B. Clark] indicated that he felt the quickened activity. The 61-year-old retired dentist from Seattle is not able to speak, but he is able to mouth words.According to Dr. [Chase N. Peterson], Dr. Clark pointed to his chest and indicated that he ''felt more force.'' At news conference, an editorial from the Thursday issue of The New York Times dominated the questioning. The editorial, ''Prolonging Death is No Triumph,'' questioned whether more testing should have been done on the artificial heart so it could have been perfected before the implantation experiment. In the first question of the conference, Robert Bazell of NBC News asked, ''What effect, if any, the severe criticism was having on Dr. DeVries and other members of the research team?'' ''You will have to decide if this was premature or not,'' Dr. Peterson said. ''We've had 15 years of animal experimentation and hundreds of animals have been subjected to this. Dr. Clark had observed an artificial heart operation on an animal.''

''He has to be thought of as a special patient in two ways,'' Dr. [Chase N. Peterson] said. First, he said, Dr. [Barney B. Clark] twice has deliberately decided ''that he would not be passive with respect to the normal termination of life.'' ''That's the kind of pioneer toughness that you do not see in everybody,'' Dr. Peterson said. A second reason for staff emotional involvement was Dr. Clark's decision to fight on when he developed a life-threatening complication two days ago. Dr. Clark's vital signs and biochemical tests are close to or at normal. ''We've seen people worse off than Dr. Clark walk out with full recovery,'' Dr. Peterson, who is the chief spokesman for the medical team, said

''See, the world is rooting for you,'' Mrs. [Barney B. Clark] said to lift her husband's courage as he faced his third major operation in 13 days. Dr. Clark smiled and told the doctors to take him to the operating room, according to a medical source close to the case. It was in those few moments Tuesday that Dr. Clark first learned the magnitude of the attention that has been focused on him and his struggle to recover from complications to become the first human to live with a permanent artificial heart. Dr. Chase N. Peterson, the university's vice president for health sciences, said at a news conference that Dr. Clark had to be regarded as ''worse off'' now than he was before the latest operation. The reasons, Dr. Peterson said, were because it was his third time in such a short period that the patient had had an operation and general anesthesia and because he had a patch of pneumonia. Mental Status Brighter Mrs. Clark told doctors today that she believed the quality of her husband's mental status, as well as the length of the periods that he was lucid, had improved significantly since the latest operation. Members of the medical team headed by Dr. William C. DeVries also agreed that her husband ''is brighter now than before surgery,'' Dr. Peterson said
