A patient on levothyroxine reports chest pain and palpitations. What is the nurse's priority action?

Choice A rationale Chest pain and palpitations in a patient taking levothyroxine can be signs of thyroid hormone overdose or hyperthyroidism, which can induce cardiac side effects. The cardiovascular system is highly sensitive to thyroid hormones. These symptoms could be indicative of myocardial ischemia, tachycardia, or dysrhythmias, which are serious and require immediate medical evaluation. The nurse's priority is to notify the healthcare provider immediately for dose adjustment or further cardiac workup. Choice B rationale Advising the patient to rest and monitor symptoms is an insufficient and potentially dangerous action. While rest may temporarily alleviate some symptoms, it does not address the underlying cause, which could be an overdose of the medication. The nurse should not delay notifying the healthcare provider, as the cardiac symptoms could escalate and lead to a more serious event, such as a myocardial infarction. Choice C rationale Antacids containing calcium or aluminum can interfere with the absorption of levothyroxine, but they are not a treatment for chest pain or palpitations related to the medication. Administering an antacid would be inappropriate and would not address the patient's serious cardiac symptoms. The nurse's focus should be on addressing the potential cardiac side effects of the medication and reporting them to the healthcare provider. Choice D rationale Increasing the dose of levothyroxine would worsen the patient's symptoms. The chest pain and palpitations suggest that the patient may be receiving too high a dose of the thyroid hormone, leading to symptoms of hyperthyroidism. Increasing the dose would further elevate the circulating thyroid hormone levels, exacerbating the cardiac side effects and increasing the risk of a serious cardiac event.
