My spouse (3rd year med student) failed Step 1 largely due to taking care of me during a neck injury

Hi!
My spouse in embarking on year three of medical school and we recently received a failing (by a hair) Step 1 score. He will be retaking the test and redoubling his efforts to prepare for Step 2.
When he took the test in May, he had been caring for me for three months. I had two cervical discs pressing on my spinal cord and I was completely “bone on bone” at two levels. Two surgeons and a neurologist warned me that a bad fall or small incident in a car could render me a quadriplegic.
I was in excruciating pain (even standing began to hurt after being upright for over two minutes) and could not bend forward or pick anything up without suffering immensely. I couldn’t drive to my many appointments because turning my head hurt too badly. We do not live near any support system so my husband spent months balancing medical school with cooking, cleaning, shopping, vet visits for my senior dog, laundry, driving me to twice weekly PT visits, and attending numerous visits with a neurologist, two surgeons, and pain management doctors.
All of this, paired with two major medical events with our dog (we are really going through it right now), resulted in his being spread much too thin and scoring poorly on Step 1. I underwent spinal surgery and am under strict restrictions that prohibit bending, twisting, lifting anything over 8 pounds, raising my arms above my head, and driving for at least 8 weeks, so his care for me continues to be mercilessly demanding.

1.) Can anyone that failed Step 1 and successfully matched into their preferred residency (he’s interested in ophthalmology, emergency medicine, urology, and ENT) speak to that experience? How did the matching process go for you?

2.) Is there a space on the application to provide this context? He intends to address it succinctly in interviews.

3.) How should this be explained but not emphasized on his application/in his personal statement? Any samples/examples shared would be a godsend.

4.) How cooked are we? He is a non traditional student, his background is in Medicinal Chemistry, he worked doing cancer research (creating compounds and performing neurosurgery on mice to test them) for several years, and he has been first author on two publications featured in Nature. His GPA is solid and he doing extremely well in clinical rotations.

Predictably, we are both very apprehensive about what this means for our future. We do not come from money and my salary as a Speech Language Pathologist is meager in the face of the student loans we must encumber. Any realistic encouragement and kindly delivered, helpful advice is appreciated!
