The nurse has reviewed the Nurses' Notes and Vital Signs at 0900. Complete the following sentence by using the lists of options. The client is most at risk for dropdowndue todropdown.

Rationale for correct choices: • Thyroid storm: The client has markedly elevated T3 and free T4 levels with clinical signs of hyperthyroidism, including weight loss, heat intolerance, irritability, and exophthalmos. Thyroid storm is an acute, life-threatening exacerbation of hyperthyroidism that can occur spontaneously or be triggered by surgery, infection, or stress. The upcoming thyroidectomy places the client at increased risk for this complication, making monitoring essential. • Excess circulating thyroid hormones: Thyroid storm results from a sudden surge in circulating thyroid hormones, which dramatically increases metabolic activity. The client’s laboratory results and clinical presentation reflect significant hormone excess. High levels of T3, T4, and TSI directly contribute to the risk of thyroid storm, as the body may respond with hyperthermia, tachycardia, and altered mental status if uncontrolled. Rationale for incorrect choices: • Myxedema coma: Myxedema coma occurs in severe hypothyroidism, characterized by low thyroid hormone levels, hypothermia, bradycardia, and altered mental status. The client has hyperthyroid laboratory values and is not hypothermic or bradycardic. There is no evidence of severe hypothyroid decompensation, making this diagnosis inappropriate. • Adrenal insufficiency: Adrenal insufficiency involves inadequate cortisol production and manifests with hypotension, hyperpigmentation, fatigue, and electrolyte disturbances. The client’s vital signs are stable, and laboratory findings reflect thyroid hormone excess rather than adrenal dysfunction. There is no indication of adrenal insufficiency in this scenario. • Iodine deficiency: Iodine deficiency can cause hypothyroidism and goiter formation but is not relevant to this client, who demonstrates autoimmune hyperthyroidism (Graves’ disease) with elevated TSI levels. Excess circulating thyroid hormones, not iodine deficiency, place the client at risk for thyroid storm. • Hypothyroidism: Hypothyroidism involves low thyroid hormone levels with slowed metabolism, weight gain, and cold intolerance. This client has elevated thyroid hormones and hypermetabolic symptoms, which are opposite to hypothyroidism. Thus, it does not explain the current risk of thyroid storm.
