NSG550 Exam Questions and Answers
Tuberculin Skin TEST - postive result means
+ TST(Mantoux test) indicates pt immune system has been sensitized to Mycobacteium tuberculosis (TB
bacteria)
TST positive does not distinguish
between latent and active TB
CXray needed for TB why
determine latent or active TB
EX magnetic resonance imaging
soft tissue detail ligament/tendon (ACL tear)lumbar, cervial ankle
lung scan - nuclear study for ventilation/perfusion scan
assess lungs for emboli
radioactive matter(tracers) send gamma rays during scan ID CA tumors w/CT or MRI order by specialist
stress test nuclear study for
r/o CAD ex exercise or RX if pt unable to exercise
arterial US
r/o PAD
Venous Doppler Ultrasound
r/o DVT a check the circulation large veins in the legs .
shows any blockage in the veins by a blood clot or "thrombus" formation.
carotid ultrasound
• r/o stenosis
Uses soundwaves to examine and visualize structure and function of the carotid arteries
• Screens for blockage that may indicate increased risk of stroke and to evaluate placement of a stent or
the function of the artery after carotid endarterectomy
Abdominal rule AAA- abdominal aortic aneurysm screening US
find sm/med aneurysms early prevent fatal rupture
Abd Aortic Aneurysm (AAA)
E: widened and weakened arterial wall at risk of rupture
cc: midline abd pain
Dx by: CT A/P with IV contrast dye
, computed tomography (CT) (xray) is
often used asssess abnl strx; tumors blood clots, inflammation IBS/diverticular disease
barium swallow (xray is
assess esophagus stomach non invasive dx GERD
mammogram- xray is
radiographic image of the breast
Dexascan (DXA) (xray) is
bone mineral density scan
xray for specific body part is
knee back etc r/o abnl/disease ex CXray r/o pneumonia dx lung CA
what is in a complete metabolic panel (CMP)
its a test that checks:
- kidney function=bld urea nitrogen (BUN) creatinine
- electrolytes= k cl ca na
- acid/base = bicarbonate
- liver function= ALP ALT AST albumin Total Protein Bilirubin
Liver fxn tests
ALP alkaline phospatase=tumor metastasis enzyme
ALT alanine aminotransferase=elevation liver dysfxn enzyme
AST aspartate aminotransferase = AST elevation b/c cell lyse in metabolic tisse(heart liver skeletal
muscle)
albumin (protein formed in liver) liver fxn
Total proteina(albumin+globuin )
Bilirubin (adult hemolytic anemia infant jaundice)
Kidney tests
blood urea nitrogen =renal fxn & GFR (if nl liver fxn)
r/t metabolic fxn liver
excretory fxn kidney
creatinine =impaired kidney fxn
Xray dx
cause lung disease eval abnl/diseases in chest vavity ex pneumonia effusions lung CA
CT scan lung
more adv depper into lung tissue ID lesions w/ w/o contrast
