The nurse is preparing a client with Chronic Obstructive Pulmonary Disease (COPD) and a chronic productive cough for discharged home.

Which prescribed medication should the nurse review with the client to manage this symptom?

Levothyroxine is a thyroid hormone replacement medication used to treat hypothyroidism. To ensure proper absorption and effectiveness of the medication, it should be taken on an empty stomach, preferably in the morning, and at least 30 minutes before eating. Therefore, when the client indicates that they understand the need to take the medication on an empty stomach, it indicates that the education was effective.

Option b, "Avoid the use of iron supplements," is also important education for clients taking levothyroxine because iron supplements can interfere with the absorption of the medication. However, it is not the best indicator of effective education because the question asks for the statement that indicates education was effective, and option a is a more direct and specific response to the medication.

Option c, "Administer levothyroxine at bedtime," is not accurate information because the medication should be taken in the morning on an empty stomach.

Option d, "Consume foods that are high in iodine," is not recommended for clients taking levothyroxine because high amounts of iodine can interfere with thyroid function. Therefore, this statement indicates a need for further education.

Insulin glargine is a long-acting insulin that is given once daily at the same time every day via subcutaneous injection. Therefore, it is essential to teach the client self-injection skills for daily subcutaneous administration to ensure proper administration of insulin.

Option b is incorrect because insulin glargine is typically given at the same dose every day, not based on before meal blood sugar readings.

Option c is incorrect because insulin glargine is not used for the treatment of severe hypoglycemia, and it should not be administered by someone who is not trained to do so.

Option d is incorrect because ketoacidosis is a serious complication of diabetes mellitus that requires urgent medical atention, and increasing medication dosage is not appropriate for this condition.
