A nurse is reviewing medications for a client in the clinic. For each potential provider's prescription, click to specify if the potential prescription is anticipated, nonessential, or contraindicated for the client.

The client’s symptoms (weight gain, cold intolerance, fatigue, constipation, dry skin, irregular menstruation) along with low T4 and elevated TSH indicate hypothyroidism. Management focuses on thyroid hormone replacement and symptomatic relief, while avoiding medications that worsen thyroid function. Rationale: Amiodarone (Contraindicated): Amiodarone can disrupt thyroid function and may worsen hypothyroidism due to its high iodine content and effects on thyroid hormone metabolism. Levothyroxine (Anticipated): This is the standard treatment for hypothyroidism. It replaces deficient thyroid hormone (T4) and helps normalize metabolic processes. Acetaminophen (Nonessential): The client has no complaints of pain or fever, so this medication is not necessary at this time. Methimazole (Contraindicated): Methimazole is used to treat hyperthyroidism by reducing thyroid hormone production. It would worsen hypothyroidism in this client. Polyethylene glycol (Anticipated): The client reports constipation (bowel movements every 3 days), which is common in hypothyroidism. This osmotic laxative helps relieve constipation.
