Goiter — NCLEX Cheat Sheet
Enlarged thyroid glandAlso known as: enlarged thyroid · thyromegaly · swollen neck/thyroid
Use this quick-reference guide to spot, treat, and prevent Goiter on the NCLEX. Keep it handy during review and on exam day!
🩺📒 The 1-minute cheat sheet
📌 Mechanism
- Thyroid enlargement (any state)
- Iodine deficiency = classic cause
🩺 Signs
- Visible neck swelling
- Dysphagia, hoarseness, cough
🚩 Report
- Stridor/dyspnea → airway compression
- Tracheal deviation = emergency
✅ Do
- Iodine/levothyroxine per cause
- Surgery if compressing airway
📚 Goiter — 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- Goiter can be associated with hypothyroidism (Hashimoto, iodine deficiency), hyperthyroidism (Graves, toxic nodular), or normal function (euthyroid).
- Iodine deficiency is the most common worldwide cause; both too little and too much iodine can trigger enlargement.
- Large goiters may compress the trachea (dyspnea, stridor) or esophagus (dysphagia) and cause a visible neck mass.
- Workup includes TSH, free T4, thyroid antibodies, ultrasound, and radioactive iodine uptake scan to determine cause.
- Treatment depends on cause: levothyroxine for hypothyroid goiter, antithyroid drugs/radioactive iodine for hyperthyroid, and surgery for compression or malignancy.
- Pemberton sign (facial flushing/distended neck veins when arms raised) suggests significant compression from a large goiter.
Nursing priorities
What to do, in order- Assess the airway for stridor, dyspnea, and swallowing difficulty from compression.
- Monitor thyroid function tests to identify whether the patient is hypo-, hyper-, or euthyroid.
- Position the patient upright to ease breathing and swallowing with a large goiter.
- Prepare the patient for diagnostic studies (ultrasound, RAI uptake, fine-needle aspiration) and explain each.
- Provide preoperative and postoperative thyroidectomy care when surgery is indicated.
Red flags — report now
Escalate immediately- Acute respiratory distress, stridor, or inability to swallow from tracheal/esophageal compression — emergency.
- Rapidly growing, hard, or fixed nodule with hoarseness or lymphadenopathy — evaluate for thyroid cancer.
- After thyroidectomy: respiratory distress from bleeding/hematoma or laryngeal nerve damage — report immediately.
Labs & values
Numbers to know- TSH (normal ~0.4-4.0 mIU/L) — low in hyper, high in hypo
- Free T4 (normal ~0.8-1.8 ng/dL)
- Thyroid antibodies (anti-TPO, TSI) to identify autoimmune cause
Patient teaching
What patients must know- Use iodized salt and ensure adequate dietary iodine to prevent deficiency-related goiter.
- Report increasing neck size, difficulty breathing or swallowing, or a change in voice.
- Take prescribed thyroid medication consistently and keep follow-up appointments for monitoring.
❓ Goiter: NCLEX FAQs
What are the priority nursing interventions for Goiter?
Assess the airway for stridor, dyspnea, and swallowing difficulty from compression. Monitor thyroid function tests to identify whether the patient is hypo-, hyper-, or euthyroid. Position the patient upright to ease breathing and swallowing with a large goiter. Prepare the patient for diagnostic studies (ultrasound, RAI uptake, fine-needle aspiration) and explain each.
What are the warning signs of Goiter a nurse must report?
Acute respiratory distress, stridor, or inability to swallow from tracheal/esophageal compression — emergency. Rapidly growing, hard, or fixed nodule with hoarseness or lymphadenopathy — evaluate for thyroid cancer. After thyroidectomy: respiratory distress from bleeding/hematoma or laryngeal nerve damage — report immediately.
What do I need to know about Goiter for the NCLEX?
Goiter can be associated with hypothyroidism (Hashimoto, iodine deficiency), hyperthyroidism (Graves, toxic nodular), or normal function (euthyroid). Iodine deficiency is the most common worldwide cause; both too little and too much iodine can trigger enlargement. Large goiters may compress the trachea (dyspnea, stridor) or esophagus (dysphagia) and cause a visible neck mass. Workup includes TSH, free T4, thyroid antibodies, ultrasound, and radioactive iodine uptake scan to determine cause.
What patient teaching is important for Goiter?
Use iodized salt and ensure adequate dietary iodine to prevent deficiency-related goiter. Report increasing neck size, difficulty breathing or swallowing, or a change in voice. Take prescribed thyroid medication consistently and keep follow-up appointments for monitoring.
