Lid retraction

20

A

Inspect from the front both sides and the back and finally ask the pt to look slightly up whilst you stand behind them.

21
Q

Ask patient to keep head still and follow finger with eyes.

Move finger in “H” shape to test various axes of eye movement.

Observe for restriction of movements

Ask patient to report any diplopia/pain.

22
Q

Hold finger high + move finger downwards.

Delayed downward movement of the eyelids

23
Q

When closely inspecting the neck what are you looking for?

A

skin changes - erythema
Scars = thyroidectomy
Masses - LN / goitre

normal thyroid gland shouldn’t be visible

24
Q

How do you perform a water test?

A

Ask patient to take some water in their mouth + then observe the neck while they swallow it.

25
Q

When looking at masses during the water test which masses move with swallowing and which don’t move much?

A

Thyroid masses + thyroglossal cysts move WITH swallowing.

Lymph nodes will move very little.

26
Q

How do you perform a tongue test?

A

Ask patient to protrude their tongue

27
Q

When looking at masses during the tongue test which masses move up and which don’t move?

29
Q

How do you palpate the thyroid?

A

Stand behind the patient + ask them to slightly flex their neck (to relax sternocleidomastoids).

Place hands on either side of the neck + ask if pain before palpating.

Place the 3 middle fingers of each hand along the midline of the neck below the chin + locate the upper edge of the thyroid cartilage.

Move inferiorly until the cricoid cartilage is reached.

The first two rings of the trachea are located below the cricoid cartilage + the thyroid isthmus overlies this area.

Palpate thyroid isthmus using pads of your fingers + palpate each lobe of the thyroid in turn by moving your fingers out laterally from the isthmus.

30
Q

When palpating the thyroid what are you assessing?

A

Size + site
Masses
Consistency
Mobility
Position
Redo water test whilst palpating
Redo tongue test whilst palpating

31
Q

What lymph nodes do we palpate during a thyroid exam?

A

Supraclavicular.
Anterior cervical chain.
Posterior cervical chain.
Submental nodes.

32
Q

Could alternatively check ankle
