A 45 year-old male developed fever, malaise, uncontrollable hypertension, oliguria and tenderness over the transplant site four months after receiving a renal transplant. His serum creatinine is elevated and there are red blood cell casts and elevated proteins in his urine. Regarding transplant renal biopsy, which of the following is true?
A 54-year old male developed end-stage renal disease secondary to diabetes. He received a kidney transplant from a living relative. The transplant functioned well with significant improvement in his well being. However, 4 months after transplantation, he noticed tenderness in his groin over the site of transplant, fever, malaise, oliguria, and decreased urine output. Which of the following is the most valuable prognostic indicator in this patient?
A 62 year-old male with end-stage renal disease expressed interest in receiving a renal transplant, and being taken to the operation theater for transplant surgery. The kidney is placed in the lower abdomen and blood supply is established with the iliac vessels. As the surgeons connect the donor kidney to the patient’s bladder, the patient’s temperature rose to 102 F, blood pressure dropped to 80/40 mmHg and heart rate has increased to 120 beats per minute. The transplanted kidney appears cyanotic, hemorrhagic, necrotic and mottled. You suspect hyperacute rejection in this patient. What is the best treatment for this patient who is diagnosed with hyperacute rejection?

A 40 year-old woman presented to the dermatology clinic with frank, fluid filled, pruritic blisters on her forearms, hands, wrists, and legs. She reports that last week while working in her garden, she was exposed to poison ivy plants. You noticed vesicles and flaccid bullae in a linear configuration on the involved areas. Which of the following immunopathogenic mechanisms is most likely to be the cause of this skin disease?
A 46 year-old male developed a hard, painful swelling with redness and discoloration on his right shoulder. He reports 10 hours ago he received a tetanus vaccine on the site where it is hurting now. He reports that if his memory is right, his last tetanus vaccine was 3 years ago in the same site after he accidentally stepped on a nail. But he is not sure because he does not keep a record of his vaccinations. As you consider this reaction to the tetanus vaccine, what would be the best advice to give to this patient?
