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.

Explanation
A. Areas of ecchymosis on the torso. Ecchymosis on the torso, especially in non-ambulatory children, can be concerning for abuse. Unexplained bruises in unusual locations or patterns are red flags for physical abuse.
B. Mismatched clothing: Typically not an indicator of abuse but could suggest neglect.
C. Abrasions on knees: Common in active children and not specific to abuse.
D. Abdominal rebound tenderness: Could indicate abdominal pathology but not necessarily abuse.
E. Round burn marks on forearms: Could suggest burns but not specific to abuse without further context.
Correct Answer is D
Explanation
A. Decreased thyrotropin receptor antibodies: Graves' disease is characterized by the presence of thyrotropin receptor antibodies, so they are typically increased, not decreased.
B. Decreased free thyroxine index: Graves' disease typically results in increased levels of thyroid hormones, not decreased.
C. Decreased triiodothyronine: T3 levels may be elevated in Graves' disease due to increased thyroid hormone production.
D. Decreased thyroid-stimulating hormone (TSH): Graves' disease causes excessive thyroid hormone production, leading to suppressed TSH levels. TSH is typically low in hyperthyroidism because the thyroid gland is overactive and not being stimulated by the pituitary gland.
