"That would be a lot less common, but theoretically it would be a possibility," the doctor said.
Moments later, the pregnant woman asks: what would happen if she went into labor and the fetus emerged alive.
"It won't," the doctor said.
"But if it, if it does survive, like what would you do, like?" the woman asks.
"Nothing," the doctor responds. "So at this gestational age, um, there's really not the possibility. A fetus is not developed enough that it can survive outside of the uterus, at this point."
"So you wouldn't like resuscitate it, or like give it anything to help it survive?" the woman asks.
"No," the doctor says. "Even if you were pregnant at the same time with a very desired pregnancy, and you had the exact same thing happen, spontaneously on your own at 23 week two days in the hospital, we would still say, 'Do you want us to try to resuscitate? Our chances aren't good.' But it's kinda one of those things that if it makes the parents feel better, we'll give it a shot between 23 to 24 weeks."
Later on tape, another women identified by Live Action as a counselor, makes similar comments.
Rose said her group wants investigations.
"We're looking for prosecutions where there may be criminal acts going on. We're looking for the de-licensing of these so-called doctors and their clinics so they're no longer allowed to operate. And we're also looking for the de-funding of any federal or state or local taxpayer dollars that are going to these acts," she said.
CNN spoke with Mercer on Wednesday. She acknowledged previously doing a resident rotation at Family Planning but was not aware of the existence of the video or any role in it.
When informed about the video, Mercer responded, "That's interesting," adding that she'd need to go back and look over records of a conversation with the pregnant woman in question.
Mercer was familiar with laws that mandates a doctor must work to save a fetus that emerged alive during an abortion.
"You have to evaluate for the ability to do so. Absolutely," Mercer said.
Asked if she could recall ever saying otherwise, Mercer responded: "No. Not that I remember."
Mercer is a physician resident in training at Banner Good Samaritan Medical Center. Bill Byron, vice president of public relations, spoke with CNN in a phone interview.
"The issue of what, let's say Dr. Mercer, would or wouldn't do, according to Live Action -- she's a resident. And a resident is not going to do anything without being supervised, obviously, in any decisionmaking from the perspective of the attending physician in the office," Byron said.
"The second thing is that, when you look at Arizona, some of our statutes ... is that, by law, if a fetus was deemed as viable or showed signs of viability, a second physician has to be in the room who's going to assume the care of that fetus."
Byron added that "nowhere do I see where she says that 'Hey, if your baby comes out alive, I'm ... going to let it die.'"
