Mabel Tseng

Edit

Mabel Tseng is a resident from Pac-North who got hired at GSM after Pac-North closed.

History[]

Interview[]

After the staff of Pac-North was informed the hospital was purchased by the Catherine Fox Foundation, Mabel went over to Grey Sloan in order to have an interview to keep her job. ("Save the Last Dance for Me")

Working at Grey Sloan[]

Mabel participated in a skills lab at Grey Sloan. During the lab, she corrected Zander Perez on something and got Richard to back her up, though they both noticed he didn't seem enthused to be working with them. He later sent them all home early. ("A Diagnosis")

Later, Mabel did another skills lab with the other residents, though they didn't take it seriously. That same day, she also rounded on Ava Gutierrez with Richard Webber. ("Snowblind")

Richard's Surgery[]

Mabel was among the medical staff in the gallery watching Richard's explantation and hip replacement. ("Put on a Happy Face")

Guarding the PPE[]

When a shipment of PPE arrived at the hospital, which they expected to contain masks and gloves, Tom assigned Mabel and Taryn to guard it as they opened it. However, when thy opened the boxes, they learned it was all booties and no masks. ("All Tomorrow's Parties")

Mabel was briefly on Meredith's case after she was diagnosed with Covid-19 before a new rule was implemented disallowing interns and residents to work on any patients with Covid or suspected Covid. Later, while waiting in line to be tested for Covid, Mabel was pulled out of line to teach Sara Ortiz the proper way to don and doff PPE after Owen noticed she was not wearing it properly. ("My Happy Ending")

Dave Oyadomari[]

When Dave Oyadomari came back into the ER after falling off a stepladder and injuring himself, Mabel ended up on the case. Due to his being Asian, she quickly realized he'd been misdiagnosed with appendicitis due to a prior ER visit and instead had right-sided diverticulitis, which had perforated after he was sent home. Owen allowed her to scrub in due to her catching the correct diagnosis. After Dave's surgery, Mabel went to talk to Owen about how his medical care, which was centered on European norms, had led to Dave being seriously injured, causing him a month off work that would otherwise have been avoided. However, before she could confront him, Nico sent her out of the room, having previously advised her not to risk her residency over it. Instead, he confronted Owen himself. ("You'll Never Walk Alone")

Tad[]

After Tad was shot in the head with an arrow, Mabel greeted the aid car in the ambulance bay. When she saw they'd rigged a hammock in the aid car to hold his head up as it couldn't rest flat on the gurney, she called it genius. She told the firefighters that she had trauma and neurosurgery waiting for him. ("Make No Mistake, He's Mine")

Chad Anderson[]

When Chad Anderson was brought to the ER with COVID symptoms after collapsing while jogging, Mabel treated him in the ER, though he mistook her for a nurse. Later, when Chad signed himself out against medical advice, Mabel treated him again just outside the hospital when he collapsed again. He died shortly afterward. ("Sign O' the Times")

Surgical Contest[]

In order to inspire the residents and help them catch up on their surgical education, Richard had them all come in early one morning to start a surgical contest starting in the skills lab. He explained that they'd be judge in four areas: laparascopic, suturing, vascular skills, and endoscopic techniques. At the end of the day, the resident with the highest score would scrub in on a surgery at their skill level. They started with laparascopic skills. After that, they practiced sutures. He gave them 20 seconds to tie three square knots without moving the soda can where the ties were attached. When the time was up, Link declared Levi the winner. They also used a computer came to practice endoscopic skills, with Mabel beating Taryn when they went head-to-head. After that finished, with all points tallied, Richard declared Levi the overall winner and said he'd get to scrub in on Robin Jeter, who had a foreign body obstructing her intestines.

The extraction went well, with Taryn assisting, but when he went to close, he struggled. Bailey turned on the speaker in the gallery, where the other residents were watching, and they all offered up tips and with their help, Levi was able to finish the surgery and close. ("Some Kind of Tomorrow")

Grand Rounds[]

The residents were told they'd have a surprise guest for grand rounds one day. Right before it started, they learned that guest was Addison Forbes Montgomery. When they met, she quizzed Levi on a medical fact related to her case and when he got it right, told him he'd be presenting the case. She then took them to meet Tovah Freedman, who had had a hysterectomy due to placental abruption and then had lost her husband. She was there in the hopes that a uterine transplant could help her conceive and carry a healthy pregnancy. The residents all observed the surgery and answered questions as Addison asked them until the HVAC system went offline and some of them were called away to help move patients and cancel surgeries. Despite this, Addison completed her surgery and afterward, the residents followed Meredith and Addison and continued their gossip. When they saw them exiting the elevator with Addison crying, they assumed Meredith had said something to make her cry. ("Hotter Than Hell")

The Webber Method[]

Wanting to train up the residents quickly to avoid some of the fallout of the physician shortage, Richard deployed The Webber Method when he took back over as residency director. This involved having the residents take the lead on several cholecystectomy patients, operating on a staggered schedule so the attending could rotate through ORs to be available to help during the most complicated part of the surgery. Taryn faced a complication when her patient began bleeding profusely, forcing her to convert to an open procedure, but, with Bailey's help, she was able to finish the surgery successfully. In total, 13 patients were treated using this method. ("With a Little Help From My Friends")

The residents enjoyed this new teaching method and eagerly awaited each day. Mabel did an echo on Vic Hughes's heart after she was electrocuted at a scene. ("Bottle Up and Explode!")

Mabel and Levi went to a recruitment fair, where they explained The Webber Method and how it allowed the residents to get more experience and treat more patients in less time. The medical students were confused by their explanation and failed to understand how it was better than other programs. ("Today Was a Fairytale")

Mabel was assigned to work on a heart transplant. ("It Came Upon a Midnight Clear")

When The Webber Method resulted in the death of Devon Gomez, Mabel attended an M&M conference to determine how they could prevent it from happening again. After the conference, Mabel worked with Amelia on Francesca Lyons, who had severe lower back pain which was eventually attributed to endometriosis. ("Living In a House Divided")

Hamilton's Surgery[]

After Levi quit, the other residents were only getting assigned simple procedures, which they considered a form of punishment. When Richard didn't show up for work, they questioned what they were supposed to do. Meredith, who was operating on David Hamilton that day, went to Hamilton and asked if she could use his surgery as a teaching opportunity and allow all hospital staff to observe. The residents were eager to be part of this. Before the surgery started, Meredith explained what they were doing and gave them time to ask questions. The surgery then proceeded and went well. ("Legacy")

Laura Eames[]

Mabel worked on the case of Laura Eames, who was 22 weeks pregnant with mitral valve insufficiency. She scrubbed in on Laura's surgery. While they were workin on Laura, they talked about Laura trying to set her brother up with Jo. ("Put the Squeeze On Me")

Fierce Fernanda[]

When the residents learned that Fernanda Lima's surgery had been changed from a Ross Procedure to a Ross-Konno Procedure, they were eager to watch it. However, Owen came to them and told them to go see patients to help cover the physician shortage. Specifically, he said that Mabel was supposed to be covering the ICU and hadn't turned in her monthly case load report. ("Road Trippin'")

Kidney Xenotransplant[]

Mabel and the other residents were called to do grand rounds with Nick Marsh and Meredith Grey. They arrived to find Nick with the patient, Mason Taylor, who was brain dead after being struck by a drunk driver. His wife wanted to donate his organs, but UNOS rejected them, so she donated his body for research. Nick explained that they would be transplanting a genetically modified pig kidney into Mason's body in the hopes that they could perfect the technology, which would eliminate the wait for donor organs. He transplanted the kidney near the groin so they had better blood supply and could see the kidney as they waited to see if it would work. After the surgery, they celebrated that the kidney was producing urine. When the kidney later stopped working, Nick had them do a biopsy and sent the residents away to avoid screaming at them. Then he did everything he could to save the kidney, but started to lose faith. Meredith suggested using epinephrine, which worked and Jordan reported that the kidney was working again. ("Put It to the Test")

Alice Tom[]

When Mabel learned that Alice Tom was bring treated at the hospital after being attacked at a bus stop for being Asian-American, she decided to stay at the hospital to watch her surgery instead of going home. While she watched, she told Levi that no one stopped to help Alice or call for help or even record the attack. ("Stronger Than Hate")

Program Evaluation and Shutdown[]

Mabel was working the day Jamarah Blake returned to the hospital to evaluate the residency program. She donated blood that day in an attempt to help lessen the burden of the blood shortage. Then she watched Meredith and Nick attempt to remove Cora's pancreatic tumor in an ex-vivo surgery. ("Out for Blood")

She later helped the other residents get the word out on social media that the hospital needed blood, drawing in several donors. At the end of the day, when the surgical residency program was shut down, she packed up her things. ("You Are the Blood")

Relationships[]

Familial[]

Her grandparents were sent to an interment camp at Jerome. ("You'll Never Walk Alone")

Career[]

She's a second-year resident. She was working at Pacific Northwest General Hospital. When it was purchased, she came over to Grey Sloan Memorial Hospital to interview to keep her job. She was hired at Grey Sloan.
