46
What should be the position of the patient during thyroid examination?
The patient should be sitting upright on a chair or the edge of a bed.
47
What does inspection of the thyroid gland involve?
1. Look at the thyroid region. 2. If the gland is quit enlarged (goitre) --> may notice it protruding as a swelling just below the thyroid cartilage. 3. Normal thyroid gland is usually neither visible nor palpable.
48
What is the location of thyroid gland?
Lies 2-3cm below the thyroid cartilage and has 2 equal lobes connected by a narrow isthmus.
49
What should be asked if the a localized or generalized swelling is visible on the thyroid?
Ask the patient to take a mouthful of water then shallow - watch the neck swelling carefully. ALSO, ask the patient to protrude their tongue and watch the neck swelling.
50
Will enlarged lymph nodes move during shallowing?
NO - Hardly move.
51
Will thyroglossal cysts move with shallowing?
Yes - will move upwards with protrusion of the tongue.
52
What should be examined regarding the rest of the neck?

53
Palpation of the thyroid should be done from behind?
YES - Stand behind the patient and place a hand either side of their neck. Patient's neck should be slightly flexed to relax the sternomastoids.
54
What are the steps during thyroid examination?
1. Ask if there is any tenderness. 2. Place the 3 middle fingers of either hand along the midline of the neck, just below the chin. 3. Gently "walk" your fingers down until you reach the thyroid gland. 4. If enlarged - determine if symmetrical. 5. Are there any discrete nodules? 6. Assess size, shape, mobility of any swelling. 7. Repeat examination while the patient shallows. 8. Ask them to hold a small amount of water in their mouth - then ask them to shallow once your hands are in position. 9. Consider consistency of any palpable thyroid tissue. 10. Feel for a palpable thrill which may be present in metabolically active thyrotoxicosis.
55
What may be the consistency of thyroid gland?
1. Soft - normal. 2. Firm - simple goitre. 3. Rubbery hard - Hashimoto's 4. Stony hard - cancer, cystic calcification, fibrosis, Riedel's.

58
What does percussion of the thyroid gland involve?
1. Percuss downwards from the sternal notch. | 2. In retrosternal enlargement the percussion note over the manubrosternum is dull as opposed to the normal resonance.
59
What does auscaltation of the thyroid involve?
1. Apply the diaphragm of the stethoscope over each lobe of the thyroid gland + auscultate for a bruit. 2. Soft bruit is indicative of incr. blood flow which is characteristic of the hyperthyroid goitre seen in Graves. 3. You may beed to occlude venous return within the IVJ to rule out a venous hum 4. Listen over the aortic area to ensure that the thyroid bruit is not, in fact, an outflow obstruction murmur conducted to the root of the neck.

62
How do we examine the thyroid functional status?
1. Observe the patient's composure (relaxed, agitated, fidgety). 2. Measure the HR and note if the patient is in atrial fibrillation. 3. Inspect the hands --> Erythema, warmth, thyroid acropachy --> Phalangeal bone overgrowth similar to pulmonary osteopathy. 4. Feel the palms - sweat/dry? 5. Look for peripheral tremor - Ask patient to stretch out their arms. 6. Inspect the face - Exophthalmos, proptosis, hypothyroid features. 7. Examine the eyes. 8. Examine the thyroid and neck. 9.

71
What causes lid retraction?
