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. "Take this medication before a meal or several hours after a meal." Levothyroxine absorption can be affected by food, so it's generally recommended to take it on an empty stomach to ensure consistent absorption. Food, particularly high-fiber or calcium-rich foods, can interfere with levothyroxine absorption, hence taking it before meals or a few hours after meals helps optimize its effectiveness.
B. "Take this medication during your morning meal.": This may not ensure consistent absorption as food can still interfere with medication absorption.
C. "Take this medication with a full glass of water or fruit juice.": While water is recommended for swallowing pills, it doesn't address timing or food interactions.
D. "Take this medication with high-protein foods.": Protein content in food does not affect levothyroxine absorption directly.
