A client on a medical-surgical unit has been diagnosed with Guillain-Barre Syndrome. The nurse understands that in addition to supportive care, which treatment can be used within the first 2 weeks of symptom onset?

A. This option describes a phenomenon seen in heparin-induced thrombocytopenia (HIT), not in immune thrombocytopenic purpura (ITP). In HIT, antibodies against the PF4-heparin complex can cause platelet activation and aggregation, leading to thrombocytopenia. However, this is not characteristic of ITP.
B. Abnormally long von Willebrand factor is seen in von Willebrand disease (VWD), not in ITP. VWD is a bleeding disorder caused by deficiency or dysfunction of von Willebrand factor, which plays a key role in platelet adhesion and aggregation. It is not typically associated with ITP.

C. ADAMTS13 deficiency is characteristic of thrombotic thrombocytopenic purpura (TTP), not ITP. TTP is a rare blood disorder where small blood clots form in blood vessels throughout the body, leading to thrombocytopenia (low platelet count) and other complications. It is distinct from ITP.
D. In immune thrombocytopenic purpura (ITP), the immune system mistakenly attacks and destroys platelets, leading to a low platelet count. Antibodies, particularly anti-platelet antibodies such as anti-GP IIb/IIIa or anti-GP Ib/IX, coat the surface of platelets. These antibody-coated platelets are recognized and destroyed by macrophages in the spleen and liver, contributing to thrombocytopenia.

A. A client with myasthenia gravis who has bilateral ptosis and a positive edrophonium test is likely experiencing a myasthenic crisis, which is a life-threatening condition that requires immediate attention. This client would be the priority because they may require rapid intervention to maintain airway and breathing.
B. Bell's palsy is characterized by sudden onset of facial paralysis due to inflammation of the facial nerve. While Bell's palsy can be distressing for the client, it does not typically require urgent intervention unless there are complications such as corneal abrasion due to inability to close the eye.
C. Parkinson's disease is a chronic neurodegenerative disorder characterized by motor symptoms such as tremors, rigidity, bradykinesia (slowness of movement), and postural instability. While this client requires ongoing assessment and care, the symptoms described do not typically indicate an acute or urgent need for intervention.
D. A client with multiple sclerosis who has bladder flaccidity and is retaining urine needs assessment and intervention to prevent complications such as urinary tract infections or renal damage. However, this is not as immediately life-threatening as a myasthenic crisis.
