Exam 4 Flashcards
reasons for urinary catheterization
relieve urinary retention; obtain sterile urine specimen; accurate measurement of urinary output in critically ill pt; comfort/end of life care; assisting in healing sacral or perineal wounds in incontinent pts; need for empty bladder related to surgical procedure
difference between hard rectangle catheter collection bag and soft circular
hard rectangular capture device is more accurate when measuring urine output; soft catheter collection bag needs to be poured out to be measured accurately
the spout on the catheter is…
clean not sterile
CAUTIs
catheter associated UTI; most common hospital acquired infection; avoid catheterization whenever possible; remove catheters as soon as possible; duration of catheter use is biggest risk factor for developing UTI
catheter is not to be placed for what reason
if pt is incontinent only; try comode or toileting time prior
types of urinary catheters
robinson 1 way/straight cath, robinson silicon 2 way catheter, coude latex 2 way catheter with rigid curved tip for those who may have obstruction like BPH; robinson latex 3 way catheter
in men when inserting catheter…
insert all the way to the biforcation then inflate balloon
if pain when inflating balloon of catheter…
deflate and insert further then re-inflate; pain d/t inflation in urethra
coude catheter
curved tip usually used in males; insert with curve up
suprapubic catheter
surgically inserted catheter; used for long term; anchored in place with a balloon; decreased risk for fecal contamination; used in situations where cannot enter urethra d/t blockage or trauma; cannula exits from bladder through abdomen
positions for catheter insertion
men are supine; women are dorsal recombinant (first choice) or sims or lateral position
common sizes of catheters used
16-20 french; larger number is larger size unlike catheter
green port on side of catheter connected to drainage tube
used for collecting sterile urine specimen
components of 3 way catheter
balloon port, drainage port with urine specimen capturing port, and irrigation port used to administer fluid to remove clots blood and debris
ileal conduit urinary diversion
used as an incontinent urinary diversion; ureters attached to a channel instead of bladder that travel to stoma and out into collection bag; channel usually made out of small intestine
collection bag for ileal conduit urinary diversion
empty bag at 1/3 to 1/2 fullness; used long term; can be used for short term but is hard to reverse once created; want 1/8 of skin around stoma exposed
urinary retention reservoir
also known as continent cutaneous reservoir; can control release of urine via straight cath through stoma; stoma is attached to a created bladder (knock pouch) that functions like a normal bladder would (kidneys transport urine through ureters to create (bladder); no need to worry about kin breakdown as there is no collection bag or adhesive
orthotopic neobladder
continent diversion to urethra; new bladder still connected to urethra and ureters; can still urinate like normal; used in situations where individuals have cancer
bowel diversion/ostomy
diversion from bowel to stoma; mucosal intestine brought out of abdominal wall; can be permanent or temporary; temporary used to allow bowel to rest
temporary ostomy
might be used to allow bowel to rest and repair itself related to inflammatory disease like crohns or after certain types of intestinal surgery or after injury; once issue has resolved then patient goes back for second surgery to reverse ostomy or bowel diversion
