201 Midterm Flashcards
indications for a urinary catheter (short term)
- acute urinary retention
- bladder decompression during and following surgery
- monitoring urinary output
- residual urine > 500 mL post-void residual (PVR) in adults, and >250 mL in the frail elderly
- In/out urine sample (C&S)
- Epidural anesthesia
indications for a urinary catheter (long term)
- urinary incontinence with urinary retention
- chronic urinary retention
- management of non-healing stage 3 or 4 PI in the perineal/sacral area with urinary incontinence
- comfort care for palliative care
Types of catheters
1 way (in/out catheterization)
2 way (regular foley -> one channel for balloon, one for urine drainage)
3 way (bladder irrigation, one channel for balloon, one for urine drainage, and one for irrigation fluid)
Types of catheter composition
- plastic
- latex
- silicone
- silicone coated (silastic)
Crude tip catheter
used for males with an enlarged prostate
has an upturned end
urinary catheter sizes
6 Fr - 36 Fr in diameter
the higher the number the larger the diameter of the cath
age 0-12: 6 Fr - 12 Fr
female: varies, initially 12 Fr - 14 Fr
male: varies, initially 14 Fr - 16 Fr
Hematuria/CBI (continuous bladder irrigation): 20 Fr - 24 Fr
Catheter balloon sizes
10 mL for regular foley catheter
30 mL for 3 way catheters
stat lock
sticks to patients thigh
secures urinary catheter to prevent complications such as pulling it out
urinary drainage bags
always hang bag below the bladder
leg bag -> small
overnight drainage bag -> large
urine meter drainage bag -> provides accurate urine output measurements
benefits of urinary catheterization
improved
- skin integrity for incontinent pts
- regular drainage for urinary retention pts
- convenient for nurse assessments
- comfort measure for palliative pts
- constant monitoring for urine output
- helpful for surgical procedures
risks of urinary catheterization
- infection, UTI
- trauma
How to prevent UTIs
only use for specific medical reasons and not nurse convenience
consider other options -> condom cath, incontinence products
assess catheter daily
remove catheter as soon as possible
Nurse considerations to prevent UTIs
bladder irrigation is not recommended -> change catheter if plugged
empty drainage bad when less than 2/3 full (at least every 8 hours)
change catheter every 8 - 12 weeks, or more frequent
change cath bags monthly or when soiled
encourage client to drink 1.5 - 2L daily
avoid constipation
when switching from leg bag to overnight bag clean bags with soapy water or 1:2 vinegar solution
avoid opening the system at night -> you can attach night bag to leg bag with connection tubing at night
weighing urine
always remember to zero the weight of the container first, before filling it with urine
hourly urine output
hourly output should be >30 mL
24hr output should be 800 - 2000 mL
report to health care provider if output is <30mL for more than 2 hours or if its over 2000 - 2500mL daily
asepsis
the process for keeping away disease producing microorganisms
medical asepsis
aka. clean technique
includes procedures used to reduce and prevent the spread of microorganisms -> hand hygiene
contamination
after an object becomes unsterile or unclean, it is considered contaminated
C&S Urine Specimen Collection (principles of asepsis)
wear clean disposable gloves
use a sterile syringe, sterile container, and sterile C&S transfer straw kit when collecting sample
clean the port on the catheter tubing with an alcohol swab before drawing the sample
don’t contaminate the straw end by touching it or placing it on a surface
place the labelled specimen tube in a clean biohazard bag
How to obtain a sterile urine specimen from an indwelling urinary catheter
gather supplies, hand hygiene, and don clean gloves
apply clamp below the urine sampling port, to let urine collect in the top portion of the tubing
after 10-15 mins, re-perform hand hygiene, don gloves and swab port opening with an alcohol swab for 15-30 seconds
attach sterile 10 mL syringe to port and withdraw at least 5 mL of urine
transfer urine into a sterile C&S container (IH - pink top)
open straw transfer kit and put the tip into the urine on a stable surface
push the grey top tube into the transfer straw, piercing top of the tube
hold tube until it stops filling (3-4mL)
mix tube 8-10 times to mix preservative (boric acid)
label tube and put into the biohazard bag
DOCUMENTING
document in the Kardex and in the narrative notes
HOUDINI
indications for removal, allows for nurses to independently make a decision to remove a catheter without a doctor order
H = Hematuria (gross)
O= Obstruction/retention
U = Urology, gynaecology, vascular, or general surgery
D = Decubitus ulcer (PI) if incontinent with stage 3-4 injury
I = input/output in critically ill patients
N = nursing, end of life/comfort care
I = immobilization or prolonged peri-operative time
if yes to any of these, you can’t take the catheter out
removing a urinary catheter
check reason/order to remove catheter
wash hands
place blue pad between legs
detached catheter from where its attached to the leg
apply clean gloves
compress the plunger and the pull back 0.5 mL
gently insert the syringe into the balloon inflation valve
the plunger will fill up with fluid from the balloon
once all the fluid is out gently pull the catheter and fold the blue pad over and throw away
wash and dry perineal area
document the procedure and assessment date -> time removed, intactness of catheter, amount/colour/clarity of urine in the bag
febrile
having or showing the symptoms of a fever
Heart sound placements
aortic = right 2nd ICS
pulmonic = left 2nd ICS
erbs = left 3rd ICS
tricuspid = left 4th or 5th ICS
mitral/apex = 5th ICS
