A client is newly diagnosed with hypothyroidism. Levothyroxine (Synthroid) is prescribed. The nurse who plans to teach this client about the medication should include that the appropriate method for taking the medication is:
With food
With milk
On an empty stomach
With fruit juice
The Correct Answer is C
A. With food: Levothyroxine should not be taken with food because it can interfere with the absorption of the medication. Food, especially high-fiber meals, can reduce the effectiveness of levothyroxine.
B. With milk: Milk contains calcium, which is known to interfere with the absorption of levothyroxine. Taking the medication with milk would reduce its effectiveness and could necessitate a higher dose, or lead to fluctuations in thyroid hormone levels.
C. On an empty stomach: Levothyroxine should be taken on an empty stomach, typically 30 to 60 minutes before eating or drinking anything, except water, to ensure optimal absorption and effectiveness.
D. With fruit juice: Fruit juice is not ideal for taking levothyroxine, as it can also affect absorption, especially grapefruit juice. It is best to take the medication with water only.

Correct Answer is C
Explanation
A. At bedtime: Thyroid replacement therapy, such as levothyroxine, should not be taken at bedtime because absorption may be reduced due to the body’s metabolism slowing down during sleep. The medication is best absorbed when taken on an empty stomach.
B. With the evening meal: Levothyroxine should not be taken with food, as certain foods (like those rich in fiber, calcium, and iron) can interfere with its absorption. It should be taken on an empty stomach.
C. 30 minutes before breakfast and other medication: Levothyroxine should be taken 30 minutes to 1 hour before breakfast with a full glass of water. This allows the medication to be absorbed properly without interference from food or other medications.
D. With the noon meal: Taking levothyroxine with meals can reduce its absorption, and the patient should avoid food for at least 30 minutes after taking the medication. Taking it before breakfast is the most effective.
Correct Answer is B
Explanation
A. Eat a high-protein diet: A high-protein diet is not specifically recommended for improving blood glucose control in type 2 diabetes. A balanced diet with a focus on carbohydrates, fiber, and portion control is more effective for long-term management.
B. Lose weight: Weight loss is one of the most effective ways to improve blood sugar control in type 2 diabetes. It reduces insulin resistance, enhances insulin sensitivity, and leads to better overall glucose management.
C. Take insulin: Insulin is typically not the first treatment for type 2 diabetes, especially in individuals who are overweight. Lifestyle changes, including diet and exercise, are generally prioritized before moving to insulin therapy.
D. Take more metformin (Glucophage): While metformin is an important medication, weight loss through lifestyle modifications often has a more significant and lasting impact on blood sugar control than simply increasing the dosage of medication.
