A nurse is teaching a newly licensed nurse about heparin-induced thrombocytopenia. Which of the following risk factors for this disorder should the nurse include in the teaching?
Systemic lupus erythematosus
Placental abruption
Heparin therapy for deep-vein thrombosis
Warfarin therapy for atrial fibrillation
The Correct Answer is C
A. Systemic lupus erythematosus (SLE): SLE is an autoimmune disease but is not directly linked to the pathophysiology of HIT.
B. Placental abruption: Placental abruption is a complication of pregnancy and is not a risk factor for HIT.
C. Heparin therapy for deep-vein thrombosis (DVT): Correct Answer. Heparin therapy itself, especially in the treatment of deep-vein thrombosis, is a significant risk factor for developing HIT due to the exposure to heparin.
D. Warfarin therapy for atrial fibrillation: Warfarin is not associated with the development of HIT.

Correct Answer is A
Explanation
A. "You will need to use a bathroom separate from other household members." This prevents others from exposure to radioiodine through bodily fluids. Radioiodine is excreted primarily through urine and to a lesser extent through saliva and sweat, necessitating separate bathroom use to minimize radiation exposure to others.
B. "You will need to remain at the hospital for the entire time the radioiodine is radioactive." Most RAI treatments for hyperthyroidism are done on an outpatient basis.
C. "A low fiber diet will be necessary." Unrelated to radioiodine treatment. There is no specific dietary restriction related to fiber for RAI treatment.
D. "Additional Immunizations will be needed for full protection." Not relevant to radioiodine treatment. Radioiodine treatment does not require additional immunizations.
Correct Answer is B
Explanation
A. "DIC is characterized by an elevated platelet count." Incorrect; DIC typically causes thrombocytopenia.
B. "DIC is caused by abnormal coagulation involving fibrinogen." DIC involves widespread activation of coagulation factors leading to the formation of microthrombi and consumption of clotting factors like fibrinogen. Understanding the pathophysiology helps in managing DIC effectively.
C. "DIC is controllable with lifelong heparin usage." Heparin is not used in DIC management due to the risk of bleeding.
D. "DIC is a genetic disorder involving a vitamin K deficiency." DIC is not genetic and is not caused by vitamin K deficiency.
