A nurse is caring for a postoperative client following a total knee replacement. Which of the following medications should the nurse anticipate the provider to prescribe to prevent the formulation of a deep vein thrombosis (DVT)?
Enoxaparin
Alteplase (tPA)
Warfarin
Clopidogrel
The Correct Answer is A
A. Enoxaparin. Enoxaparin is a low molecular weight heparin used for prophylaxis against DVT. It works by inhibiting clotting factors and is commonly used postoperatively to prevent DVT formation.
B. Alteplase (tPA): Alteplase is a thrombolytic agent used to dissolve clots and is not used for DVT prophylaxis.
C. Warfarin: Warfarin requires monitoring and has a delayed onset, making it less suitable for immediate postoperative DVT prophylaxis.
D. Clopidogrel: Clopidogrel is an antiplatelet agent and is not typically used for DVT prophylaxis postoperatively.

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.
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.
