Hypersensitivity Disorders

QuestionAnswer
Type I: Anaphylaxis Wheezing, dysrhythmias, cyanosis
Type II: Acute hemolytic reaction Fever, hypotension, chills
III: Post streptococcal glomerulonephritis Hypertension, proteinuria, edema
Type IV: Contact dermatitis Vesiculated blisters, itching, burning
Which characteristics differentiate type III immune complex hypersensitivity from type II tissue-specific (cytotoxic) hypersensitivity? -Triggered frequently by an event such as infection -Immune complexes deposited in vessels and organs -Complexes form in blood from circulating antigens and antibodies -Neutrophils try to phagocytize immune complexes
How will the nurse interpret the results of the enzyme-linked immunosorbent assay (ELISA) ordered for a patient with a type I hypersensitivity disorder? Pollen is the offending allergen.
What is the rationale behind the collaborative treatment, immunotherapy? Antigen exposure over time replaces IgE-specific antibodies with IgE-blocking antibodies, reducing lymphocyte sensitivity.
Which goal reflects collaborative treatment for patients with a type III antigen-antibody complex hypersensitivity disorder, such as systemic lupus erythematosus? Immune suppression to halt disease progression
Which finding associated with use of corticosteroids as collaborative treatment for type I hypersensitivity (allergy) will the nurse report to the patient’s health care provider? Thrombocytopenia
Which action will the nurse take first upon entering the room of a patient who has an intravenous antibiotic running and is experiencing an anaphylactic reaction? Stop the antibiotic infusion
Which interventions will the nurse determine as correct for the patient experiencing a transfusion reaction? -Stop the infusion, but not the IV. -Maintain IV patency with normal saline. -Notify the health care provider immediately. -Prepare to administer prescribed medications. -Return blood and tubing to the laboratory.
The statement “I may be able to control some things that trigger my disorder, but not all” from a patient with a type III immune-complex hypersensitivity disorder supports meeting which goal? Avoiding triggers when possible
The nurse determines which action will take priority upon recognizing a patient experiencing a febrile, non-hemolytic transfusion reaction? Discontinue the infusion.
The nurse determines which patient problem will take priority when the patient is experiencing a type III antigen-antibody complex hypersensitivity disorder? Controlling current acute exacerbation
