Study Guide NSG 550
Quiz 3
Topics: Nervous System, Reproductive, Hematology/Cancer, Miscellaneous
MRI (imaging) vs MRA/EEG/BACK & NECK:
o MRA (angiography)- visualization of blood vessels in the brain
o Both noninvasive and no radiation
o If normal- No abnormality blockage or narrowing
o Looking for issues if why pt would stroke or fainting or AV malformation.
-CVA- first 24 hr non-contrast brain CT scan for acute not MRI first
-EEG-epilepsy due to underlying dysfunction in the brain and this test is the
diagnostic test of choice; recording the electrical activity of the brain; can be helpful
for tumors, sleep disorders, etc.
-uncomplicated acute nonspecific low back pain in primary care- imaging of the
spine is withheld- so absence of red flags
-having longer 6-8 wk without improvement or red flags than MRI or CT appropriate
-red flags- cancer signs/immunosuppressing; active infection; IV drug user;
prolonged steroid use; recent trauma; fall or osteoporosis; acute onset of urinary
issues or bowel issues; global or progressive weakness, or ascending lower extremity
numbness
-neck pain: uncomplicated no imaging either; MRI, CT, or CT with myelography of
cervical spine appropriate if red flags or pain persistent
DEXA scan- bone density:
Normal: < 1 SD below normal (>–1)
Osteopenia: 1 to 2.5 SD below normal (–1 to –2.5)
Osteoporosis: > 2.5 SD below normal (<–2.5)
Recommended for test: Postmenopausal women with at least one additional risk factor (family history,
Caucasian descent, thin body habitus)
• All women over 65 years of age
• Women who would consider treatment for osteoporosis or menopause symptoms if BMD would affect
the decision
• Women who have received hormone-replacement therapy for prolonged periods
• Men or women who have hyperparathyroidism
