A patient is admitted with immune thrombocytopenia purpura (ITP). How would the nurse explain the etiology of this disorder?
1. "You are producing antibodies against your own platelets.".
2. "This is a disorder caused by an overproduction of neutrophils.".
3. "You are having a reaction to heparin therapy.".
4. "This disorder is caused by an overproduction of reticulocytes.".

Rationale 1: Immune thrombocytopenic purpura (ITP) is an autoimmune disease marked by a decrease in the number of platelets due to destruction by antibodies produced against the patient's own platelets.
Rationale 2: An overproduction of white blood cells, such as neutrophils, does not result in ITP.
Rationale 3: A reaction to heparin therapy is referred to as heparin-induced thrombocytopenia. ITP has a different etiology.
Rationale 4: An overproduction of reticulocytes, immature red blood cells, does not result in ITP.
