THYROID (ENDOCRINE) Exam Question
and Answers Latest Updates 2026 Top Rated
A+
These questions are commonly asked in medical student finals,
OSCEs, MRCP PACES, and clinical examinations focusing on
thyroid status assessment. They test knowledge of clinical signs,
differential diagnoses, and examination findings. Answers are
elaborated with explanations, pathophysiology, and clinical
relevance.
>> Question 1: What are the key peripheral signs of
**hyperthyroidism** you would look for on examination?
<<Answer>>Key signs include:
- Fine tremor (observed by placing paper on outstretched
hands)
- Warm, moist palms (palmar erythema possible)
- Onycholysis (separation of nail from bed)
- Thyroid acropachy (clubbing, seen in Graves' disease)
- Proximal myopathy (difficulty rising from chair)
,- Brisk reflexes
- Atrial fibrillation (irregularly irregular pulse)
- Hair thinning or loss
**Elaboration:** Hyperthyroidism increases metabolic rate and
sympathetic activity via excess T3/T4. Tremor and brisk reflexes
result from enhanced beta-adrenergic sensitivity. Warm/moist
skin reflects vasodilation and increased sweating. Onycholysis
and acropachy are specific to Graves' disease (autoimmune).
Proximal myopathy arises from catabolic effects on muscle.
>> Question 2: What are the key peripheral signs of
**hypothyroidism** on examination?
<<Answer>>Key signs include:
- Dry, coarse skin and hair
- Puffy face (myxedema) and non-pitting edema
- Slow-relaxing (hung-up) reflexes
- Bradycardia
- Cold intolerance (cold hands)
- Weight gain/obesity
- Hoarse voice
,- Delayed relaxation phase of deep tendon reflexes
**Elaboration:** Hypothyroidism reduces metabolic rate due to
low T3/T4. Myxedema results from glycosaminoglycan
deposition in tissues causing edema. Slow reflexes stem from
reduced muscle contractility. Bradycardia reflects decreased
cardiac output and sympathetic tone.
>> Question 3: Describe the eye signs specific to **Graves'
disease** (thyroid eye disease).
<<Answer>>
- Exophthalmos (proptosis) — forward protrusion of eyes
- Lid retraction (Dalrymple's sign) — sclera visible above cornea
- Lid lag (von Graefe's sign) — delayed descent of upper lid on
downward gaze
- Chemosis (conjunctival edema) and conjunctival injection
- Ophthalmoplegia (restricted eye movements, e.g., failure to
converge)
**Elaboration:** These are autoimmune-mediated (TSH
receptor antibodies stimulate orbital fibroblasts), causing
, inflammation, glycosaminoglycan deposition, and extraocular
muscle enlargement. Not all hyperthyroid patients have them;
they can occur in euthyroid Graves' ophthalmopathy.
>> Question 4: On palpation of the thyroid, what features
suggest a **diffuse goiter** in Graves' disease?
<<Answer>>Smooth, symmetrically enlarged thyroid, often with
a audible/palpable bruit (due to increased vascularity).
**Elaboration:** Graves' disease causes uniform hyperplasia
from TSH receptor stimulation. Bruit indicates high blood flow
from angiogenesis and hyperfunction. Tenderness is absent
(unlike thyroiditis).
>> Question 5: What palpation findings suggest **Hashimoto's
thyroiditis**?
<<Answer>>Firm, irregular, "woody" or bosselated texture; may
be diffusely enlarged or nodular; usually non-tender.
**Elaboration:** Autoimmune destruction leads to fibrosis and
lymphocytic infiltration, giving a hard, irregular feel. It often
