27
What are abscesses on the toe?
Paronychia
28
What are onychomycosis? Can you look at it and diagnose it?
Thickened nails d/t fungal infections Need culture
29
What are the causes of thickened nails?
``` Trauma Onychmycosis Eczema Circulatory problems Lichen planus Yellow nail syndrome Psoriasis Tumor ``` (TOE CLYPT)
30
What are the four causes of dry skin on the foot?
1. Insufficient sweat glands 2. Tinea pedis 3. psoriasis 4. eczema
31
What is an ulcer?
Loss of the epidermis
32
If the base of the ulcer is red, then what is the prognosis?
Good b/c there is good blood supply to the area
33
What is the scale for muscle strength? What are normal values?
0-5 5 is normal
34
You see the tendon contract, but there is no movement of the joint. Grade this muscular movement?
1/5
35
The patient is able to move foot or leg into the desired position when horizontal to exam table. Rate this MS.
2/5
36
The patient is able to perform movement with leg hanging over the side of the table or sitting. Grade this MS.
3/5
37
There is a slight decrease from normal strength. Rate this MS.
4/5
38
What is a corn?
Thickened stratum corneum in an area d/t pressure
39
What are the 3 systems evaluated in a neuro exam?
Motor Sensory ANS
40
What are the two pathways that sensation travel through?
1. Posterior column | 2. Lateral spinothalamic tract
41
Which tract are burning or cramping pain felt in?
Spinothalamic tract
42
Which tract are pins and needles or electric shock pain felt in?
Posterior column
43
What are the small fibers of the neurosensory tract?
Spinothalamic tract
44
What are the large fibers of the neurosensory tract?
Posterior column
45
Abnormality of the touch stimuli test indicated what?
Small fiber disease
46
What is the tool that you use for the touch stimuli?
Semmes-weinstein monofilament
47
When do you do the temp test?
Iff there is abnormal pain sensation
48
Lack of temperature sensation suggests what?
Small fiber disease
49
Abnormal vibration test indicates what? What is the tool used?
Large fiber disease 128 cycle tuning fork
50
How long should the tuning fork be felt in the foot?
30 seconds but for sure more than 10
51
How do you accurately grab the great toe for a proprioception test? An abnormal test is indicative of what?
on the sides, move up and down Abnormal = large fiber disease
52
True or false: an absent Achilles reflex after 80 yo is normal
True
53
What is the scale of tendon reflexes?
0-4
54
What are the knee reflexes innervated by?
L2, L3, L4
55
What are the ankle reflexes innervated by?
S1, S2
56
What is the innervation of the superficial reflex or plantar response?
L4, L5, S1, S2
57
How do you elicit a superficial reflex? What is the normal result?
Stroking the lateral aspect of the sole from the heel to the ball of the foot Toes should plantarflex
58
What is the all-in-one test for the feet? What does this indicate?
hop on one foot Indicates: 1. intact motor system of the legs 2. Normal cerebellar 3. good position sense
59
If a pt is able to stand on tiptoes, but not on the heels, what does this suggest?
Peripheral neuropathy
60
If a pt is able to stand on heels, but not on tiptoes, what does this suggest?
Spinal lesions
61
With normal vagal nerve input to the heart, the pulse at rest will (BLANK) with increase, and (BLANK) with expiration
Inspire - increase | Expiration = decrease
62
What is the Babinski response? What does this indicate?
A result of the plantar reflex response, where there is dorsiflexion of the great toe and fanning of the other toes This indicates upper motor neuron disease
63
What type of fibers compose the posterior column? Spinothalamic? (slow/fast)
Posterior column = Fast | Spinothalamic = Slow
64
What type pain is experienced via the posterior column? Spinothalamic? (burning/cramp or electric)
``` PC = Electric shocks Spinothalamic = burning ```
65
What nervous tract is able to sense temperature? (spinothalamic or posterior column)
Spinothalamic
