A nurse is providing teaching to a client who has hypothyroidism and has been prescribed levothyroxine. Which of the following medication instructions would the nurse include in the teaching?
"Take this medication before a meal or several hours after a meal."
"Take this medication during your morning meal."
"Take this medication with a full glass of water or fruit juice."
"Take this medication with high-protein foods."
The Correct Answer is A
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.

Correct Answer is C
Explanation
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 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.
