NSG 3100 Common Exam Questions and
Correct Answers
what does clean-voided mean - ANS first morning void(urine)
clean catch(mid stream) - ANS •First clean perineum with antiseptic
wipes •Begin urine stream, pause and place container under urine stream
timed urine specimen - ANS begins after discarding first specimen and ends with a final
voiding at the end of the time period.If client accidentally forgets to save urine specimen, you
must start the collection over again. put urine in ice or refigerator
normal ph for urine - ANS normal range is 6
why do we test urine for glucose - ANS diabetes
why do we test urine for ketones - ANS the diabetes are poorly controlled
why do we test urine for proteins - ANS could indicate kidney issue( glomerulonephritis)
why do we test urine for occult blood - ANS indicative of kidney or urinary tract damage
specific gravity testing - ANS #of solutes in urine
•High = fluid volume deficit/dehydration
•Low = fluid volume overload/overhydration
,what is an anoscopy - ANS viewing of the anus
What is a proctoscopy? - ANS viewing of the rectum
what is a Proctosigmoidoscopy? - ANS visual examination of the rectum and sigmoid colon
What is a colonscopy? - ANS viewing of the large intestine
what is barium? - ANS • radiopaque substance that helps with the visualization of the GI tract.
what type of barium is used for the upper and lower gi tract? - ANS •Upper GI = barium swallow
•Lower GI = barium enema
what is K.U.B. test - ANS •visualizes the kidneys, ureters, and bladder
IV pyelography - ANS •contrast medium injected via IV to visualize urinary/kidney structures
Retrograde pyelography - ANS contrast medium is instilled directly into the kidney via the
urethra bladder and ureters to visualize urinary/kidney structures
What is ultrasonography? - ANS •noninvasive test that uses reflected sound waves to
visualize the kidneys
what is a cytoscopy? - ANS lighted instrument (cystoscope) inserted into the urethra to
visualize the bladder, ureteral orifices, and urethra
what is the purpose of an xray? - ANS visualize bones
, what is the purpose of a ct scan? - ANS •(visualizes soft tissue)
•Provides a 3 dimensional image, making it more sensitive than the x-ray machine
what is the purpose of an MRI - ANS •visualizes soft tissue) •Non-
invasive technique where client is placed in a magnetic field
•Provides better contrast between normal and abnormal tissue then the CT
scan •Have to remove all metal objects
•Clients with metal implants cannot undergo an MRI
•Body tattoos can become very warm during the procedure (especially red colors)
what is nuclear imaging? - ANS •Ex: PET scan
•Involves radioactive isotopes
•Distribution of isotope is different in normal tissue then diseased tissue
what is an electrocardiography - ANS •Electrocardiography provides graphic recording of
the heart's electrical activity (ECG)
what is an angiography - ANS •à invasive procedure; uses radiopaque dye, fluoroscopy and x-
rays to view the flow through the vessels
echocardiogram - ANS •noninvasive; uses ultrasound to visualize the structures of the heart
& evaluate left ventricular function
V/Q lab scan - ANS • looks at how well gas and blood are traveling through the lungs
What is a lumbar puncture? - ANS •Lumbar Puncture (Spinal Tap)
What is paracentesis? - ANS abdomen aspiration
