ALU 101 MIDTERM EXAM QUESTIONS AND
ANSWERS SET A+
✔✔
✔✔Visual Evoked Potentials (VEP) - ✔✔1. used in dx of MS
2. detects slowing of electrical conduction due to demyelination
✔✔Evoked Potentials - ✔✔the measured electrical response of the brain to stimulation
of specific sensory pathways
✔✔Tests to determine possible secondary causes of HTN - ✔✔1. fundoscopic exam
2. EKG
3. echo
4. blood (HCT glucose, electrolytes, BUN, creat, lipids)
5. renal evaluation
✔✔Parotid Sialography - ✔✔1. dx's and helps manage parotid lesions
2. differentiates b/w intrinsic and extrinsic masses, inflammatory lesions from
neoplasms & allows visualization of stones/ductal abnormalities
✔✔Whole Body Iodine Scans are used when? - ✔✔1. after surgical removal of thyroid &
ablation of thyroid remnants to look for extraglandular metastases
2. evaluates effectiveness of tx/searches for recurrence
✔✔Nodules noted on a thyroid scan are classified as: - ✔✔1. cold: less uptake than
normal thyroid tissue (indicates increased probability of malignancy & requires further
testing)
2. functional: uptake similar to normal tissue
3. hot: greater uptake than normal tissue
✔✔Thyroid Uptake & Scans - ✔✔1. evaluates thyroid function & investigates palpable
lumps, hyperactivity, and/or enlargement of the thyroid gland
, 2. technetium can be used instead of iodine-base radionucleid agent (RAI) cannot be
used
✔✔Schirmer Tear Test - ✔✔determines if eye is producing enough tears to keep eye
moist
✔✔Tonometry - ✔✔1. measures intraocular pressure to help in dx glaucoma
2. uses puff of air or probe to gently flatten cornea
✔✔Laser & Color Doppler US - ✔✔assesses digital vascular changes & microvascular
changes associated w/ connective tissue diseases
✔✔Snellen Test - ✔✔graduated block letters placed at specific distances to measure
visual acuity
✔✔Fluorescin Angiography - ✔✔images retina & choroid vasculature of the eye to
detect diabetic retinopathy, vascular occlusions, leaks and macular degeneration
✔✔Nailfold Microscopy - ✔✔optical microscope visualizes and quantifies changes in
size, shape & number of capillaries in the digits
✔✔Skin Biopsy - ✔✔used for skin lesions that are suspicious for malignancy and to
confirm clinical dx
✔✔Somatosensory Evoked Potentials (SSEP) - ✔✔1. detects sequential activation of
nerves along a pathway
2. monitors nerve function during surgery
✔✔Brainstem Auditory Evoked Response (BAER) - ✔✔1. an electrical response to a
click or noise made in each ear
2. dx's deafness (esp. in infants)
3. response is delayed in MS
✔✔Papanicolou (PAP) Test - ✔✔most common screening test for cervical cancer
✔✔Colposcopy - ✔✔allows direct visualization of cervix, vagina & surrounding tissues
(used if PAP results are abnormal)
✔✔Ambulatory BP Monitoring - ✔✔24 hour monitor to identify White Coat Syndrome
✔✔Nerve Conduction Studies (NCS) or Nerve Conduction Velocities (NCV) - ✔✔1.
detects sensory & motor neuropathy; can differentiate demyelinating neuropathies from
axomal neuropathy
2. when performed w/ EMG, characterizes the pathology as neurogenic or myopathic
