April Layton Sexton (born November 22, 1982) is an emergency department nurse at Gaffney Chicago Medical Center. She is portrayed by Yaya DaCosta.


April is the oldest child and only daughter of Brazilian immigrants, she has a younger brother named Noah. Her parents always asserted that her brother should be the doctor, so April helped her brother through medical school and sacrificed her own career to make it happen. She is a childhood friend of Kelly Severide.

She was raised Catholic and admired St. Francis.

April appears in ten episodes of Chicago Fire , although she is only credited for eight, including the backdoor pilot, in which she decides to go on an adventure around the world after sorting things out with her old school friend and brief love interest Severide.

Her first appearance in Chicago Fire was episode 3x17, when their mutual friend who joins Squad 3 shares with Severide that April is working at Med. He decides to surprise her by showing up and invites her to Molly's. That's when he finds out April has unfinished business with him. Later on, he decides to show up again and shows her the Eminem concert tickets he kept all those years, though it is still not enough. Scott (their mutual friend) invites April for breakfast, and to her surprise Kelly is also there.

We're Lost in the Dark

April, Ethan and medical student Steve treat a paramedic extracted from a crashed ambulance. When the power goes out she offers to help Steve in the hybrid OR, but Ethan calls her away with him. They are eventually able to stabilize the patient, and throughout the ordeal April lends Steve her emotional support.

As he and April are leaving for the night, they run into Steve in the lobby. He announces that he is not coming back due to the stress of his first day in the ED, and the prospect of having to do this work for the rest of his life. Ethan wonders whether he was too focused on his patients' needs and not enough on Steve's needs, but April replies that it is normal to forget to take care of each other in stressful situations. Ethan counters that it is not normal, and that April is able to do so all the time, complimenting her mindfulness and awareness and saying she will make the "best mom ever." They express their love for each other and kiss.

In the Valley of the Shadows

April and Crockett treat a newborn baby who is brought in by her mother, who is covered in blood. April is continually annoyed by Crockett's cavalier attitude, and decides to go over his head and call DCFS because she suspects there is more going on. She is vindicated when it is discovered that the baby does not belong to the woman who brought her in, but that the woman forcibly cut the baby out of another woman's stomach. After the mother is stabilized, an ICU nurse confides in April that Crockett found out the woman did not deliver the baby by illegally drawing her blood after giving her Ativan to put her to sleep, praising Crockett as a "badass."

At the end of the episode, April agrees to start training under Maggie as her new second in command, as Maggie is struggling due to the effects of her chemotherapy.
