A nurse cares for a 32-year-old client with Graves disease who develops fever 40 C, HR 156, BP 188/92, agitation, vomiting, and altered mental status 36 hours after thyroidectomy. The nurse identifies thyroid storm. Which interventions should the nurse anticipate? Select all that apply.

Explanation
Thyroid storm is a life-threatening hypermetabolic crisis with mortality 10-25 percent. Treatment is multimodal and time-critical: beta-blocker (propranolol) for adrenergic symptoms, thionamide first to block synthesis, iodine 1 hour AFTER thionamide to block release, glucocorticoid to support adrenal function and reduce T4-to-T3 conversion, and aggressive cooling. Waiting for endocrinology before any treatment is incorrect — initiate per protocol while awaiting consult.
KR vs U ATA and Korean Endocrine Society both endorse the same multimodal protocol. Burch-Wartofsky scoring widely used in both jurisdictions. ICU monitoring with continuous cardiac monitoring is standard.
Clinical Practice GuideATA thyroid storm bundle (in order):- Beta-blocker: propranolol 60-80 mg PO q4 h or 0.5-1 mg IV q15 min for adrenergic surge- Thionamide: PTU 500-1000 mg PO load then 250 mg q4 h, OR methimazole 60-80 mg PO daily- Iodine: SSKI 5 drops q6 h or Lugol — start at least 1 hour AFTER thionamide- Glucocorticoid: hydrocortisone 100 mg IV q8 h- Cooling: acetaminophen, ice packs, cooling blanket; avoid aspirin (increases free T4)- IV fluids, electrolyte correction, treat precipitating cause
CautionAvoid aspirin and salicylates — they displace thyroid hormone from binding proteins and worsen the storm. Use acetaminophen for fever. Monitor for arrhythmias, heart failure, and rhabdomyolysis from severe hyperthermia.
Thyroid storm — Life-threatening exacerbation of hyperthyroidism with fever, tachycardia, altered mental status, and high-output heart failure. Mortality 10-25 percent. Triggered by surgery, infection, trauma, DKA, iodine load, or abrupt antithyroid withdrawal in clients with Graves disease.
Thionamide — Class of antithyroid drugs that block thyroid hormone synthesis. PTU (propylthiouracil) preferred in pregnancy first trimester and thyroid storm because it also blocks peripheral T4-to-T3 conversion. Methimazole preferred long-term due to lower hepatotoxicity. Side effects: rash, agranulocytosis, hepatotoxicity.
Burch-Wartofsky Point Scale (BWPS) — Diagnostic clinical score for thyroid storm. Categories: thermoregulation, CNS, GI/hepatic, cardiovascular, congestive heart failure, atrial fibrillation, precipitant history. Score ≥45 highly suggestive of storm; 25-44 impending storm; <25 unlikely.
