Hyperthyroidism (Graves Disease) — NCLEX Cheat Sheet
↓ TSH, ↑ T3/T4 → hypermetabolicAlso known as: overactive thyroid · Graves disease · high thyroid · fast thyroid · thyrotoxicosis
Use this quick-reference guide to spot, treat, and prevent Hyperthyroidism (Graves Disease) on the NCLEX. Keep it handy during review and on exam day!
🩺📒 The 1-minute cheat sheet
🩺 Signs
- Wt loss, ↑ HR, heat intolerance
- Exophthalmos, goiter, tremor
- Diarrhea, anxious, insomnia
🧪 Labs
- ↓ TSH, ↑ free T4/T3
- TSI antibodies + in Graves
🧪 Meds
- PTU, methimazole block synthesis
- Beta-blockers → control HR/tremor
- Radioactive iodine, thyroidectomy
🎓 Teach
- Cool room, ↑ calorie diet
- Report fever/chest pain = storm
📚 Hyperthyroidism (Graves Disease) — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Key points
Understand these first- Signs include tachycardia, palpitations, hypertension, heat intolerance, diaphoresis, and warm moist skin.
- Weight loss despite increased appetite, frequent loose stools, and fine hand tremor are characteristic.
- Patients are restless, anxious, irritable, and may have insomnia and difficulty concentrating.
- Exophthalmos (protruding eyeballs) and goiter (enlarged thyroid) are hallmark findings in Graves disease.
- TSH is low while free T3 and T4 are elevated due to feedback suppression of the pituitary.
- Untreated disease increases risk for atrial fibrillation, osteoporosis, and thyroid storm.
Nursing priorities
What to do, in order- Promote a cool, calm, quiet, low-stimulation environment to reduce metabolic demand.
- Provide a high-calorie, high-protein diet with frequent meals to offset hypermetabolism; avoid caffeine and stimulants.
- Administer antithyroid drugs (methimazole, PTU), beta blockers for symptom control, and iodine preparations as ordered.
- Monitor cardiac status, vital signs, weight, and protect bulging eyes with artificial tears, eye shields, and elevated head of bed.
- After radioactive iodine therapy, teach radiation safety precautions and monitor for resulting hypothyroidism.
Red flags — report now
Escalate immediately- Report fever, severe tachycardia, agitation, or altered mental status, which signal thyroid storm, a life-threatening emergency.
- Report new or worsening chest pain, irregular pulse, or signs of atrial fibrillation.
- Never abruptly stop antithyroid medication, as this can precipitate thyroid storm.
Labs & values
Numbers to know- TSH: low (normal 0.4-4.0 mIU/L)
- Free T4: elevated (normal 0.8-1.8 ng/dL)
- Free T3: elevated (normal 2.3-4.2 pg/mL)
Patient teaching
What patients must know- Take antithyroid medication consistently and report sore throat, fever, or signs of infection (risk of agranulocytosis).
- Report any rapid weight changes, palpitations, or worsening eye symptoms to the provider.
- After radioactive iodine, lifelong thyroid replacement is often needed because of resulting hypothyroidism.
❓ Hyperthyroidism (Graves Disease): NCLEX FAQs
What are the priority nursing interventions for Hyperthyroidism (Graves Disease)?
Promote a cool, calm, quiet, low-stimulation environment to reduce metabolic demand. Provide a high-calorie, high-protein diet with frequent meals to offset hypermetabolism; avoid caffeine and stimulants. Administer antithyroid drugs (methimazole, PTU), beta blockers for symptom control, and iodine preparations as ordered. Monitor cardiac status, vital signs, weight, and protect bulging eyes with artificial tears, eye shields, and elevated head of bed.
What are the warning signs of Hyperthyroidism (Graves Disease) a nurse must report?
Report fever, severe tachycardia, agitation, or altered mental status, which signal thyroid storm, a life-threatening emergency. Report new or worsening chest pain, irregular pulse, or signs of atrial fibrillation. Never abruptly stop antithyroid medication, as this can precipitate thyroid storm.
