A.
Take medication on an empty stomach.
B.
Avoid the use of iron supplements.
C.
Administer levothyroxine at bedtime.
D.
Consume foods that are high in iodine.
The Correct answer and Explanation is:
The correct answer is A. Take medication on an empty stomach.
Explanation:
Levothyroxine is a synthetic form of the thyroid hormone thyroxine (T4) used to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone. For optimal absorption and effectiveness of levothyroxine, it’s crucial to adhere to specific administration guidelines.
- Administration on an Empty Stomach: Taking levothyroxine on an empty stomach, usually 30 to 60 minutes before breakfast, is essential because food, particularly high-fiber foods, can interfere with the absorption of the medication. Levothyroxine is best absorbed when the stomach is empty, which helps ensure that the full dose of the medication is absorbed into the bloodstream. Food or drink can alter the absorption rate, potentially reducing the medication’s effectiveness.
- Avoiding Iron Supplements: Iron supplements, along with calcium and certain other supplements, can interfere with the absorption of levothyroxine. Ideally, these supplements should be taken at least 4 hours apart from the levothyroxine dose. However, the client’s knowledge of avoiding iron supplements is important but not as critical as taking the medication on an empty stomach.
- Administering at Bedtime: While some patients may take levothyroxine at bedtime, this is not the primary recommendation. The general guideline is to take it in the morning on an empty stomach. Administering it at bedtime might not be as effective due to possible food intake and interactions with other medications taken before bed.
- Consuming Foods High in Iodine: The consumption of iodine-rich foods is not necessary or recommended for the management of hypothyroidism with levothyroxine. Excessive iodine intake can actually affect thyroid function and hormone levels. The thyroid hormone therapy aims to normalize thyroid hormone levels without altering iodine intake.
In summary, the statement “Take medication on an empty stomach” indicates that the client understands the crucial aspect of levothyroxine administration for effective absorption and therapeutic success.
