NR 507 Week 1 Discussion:
PART 1:
John is a 19-year-old college football player who presents with sneezing, itchy eyes, and nasal congestion that worsens at night. He states that he has a history of asthma, eczema and allergies to pollen. There is also one other person on the football team that has similar symptoms. His vitals are BP 110/70, P 84, R 18, T 100 F.
Write a differential of at least three (3) possible items from the most likely to less likely. For each disease include information about the epidemiology, pathophysiology and briefly argue why this disease fits the presentation and why it might not fit the presentation.
PART 2:
A patient has been admitted into the emergency room that was in the passenger side of a car that collided with another car head on. The patient is pale, barely conscious and has a weak and thready pulse. An IV is started. The vitals are BP 80/50, P 140, T 96.0 and R 26. As the team fights to keep the patient alive they have to remove the spleen. Blood is given but it has been mistyped. A transfusion reaction occurs.
Describe the type of hypersensitivity reaction that has occurred and discuss the molecular pathophysiology of the specific type of hypersensitive reaction you have chosen.
In the event that this patient survived the car accident and the transfusion reaction which organs are most likely to be damaged and why?
