Which instruction should the nurse include in the teaching plan for a client taking propylthiouracil (PTU)?

The instruction to avoid abrupt discontinuation of propylthiouracil (PTU) is important because stopping the medication suddenly can lead to a rebound effect, causing the condition being treated—typically hyperthyroidism—to worsen. PTU is used to inhibit the production of thyroid hormones, and a gradual tapering may be necessary to allow the body to adjust and to prevent the resurgence of hyperthyroid symptoms. Ensuring that the patient understands the importance of continuing the medication as prescribed helps maintain stable thyroid hormone levels and supports effective management of their condition.

Monitoring weight and pulse is crucial in patients taking PTU, as fluctuations can indicate changes in thyroid function that need to be addressed. It’s also essential for patients to report all side effects, not just severe ones, as early detection of adverse effects can lead to timely interventions. Lastly, taking PTU with food helps to enhance its absorption and reduce gastrointestinal side effects, but the option regarding avoiding abrupt discontinuation is more critical for ensuring patient safety and treatment effectiveness.
