Q

removes debris and transient microorganisms from hands and nails

reduce resident microbial count to minimal

inhibit rapid rebound growth of microorganisms

A

purpose of surgical scrubbing

22
Q

numbered stroke

timed scrub (happy bday song)

A

2 methods of surgical scrubbing

23
Q

use scrub brush, antiseptic soap and nail cleaners

remove jewelry and watches

wash hands and arms with antiseptic soap

clean subungual

scrub for 3 minutes

scrub arms to 3 inches above elbow

repeat for other hand/arm

blot/rotate from wrist to elbow, don’t revisit area

A

guidelines for surgical scrubbing

24
Q

12 inches from sterile area

grasp gown on folded edges

no objects near

shake gently

raise arms up and put in sleeves

have someone else tie

A

sterile gowning self

25
Q

closed—hands in gown

open—hands out of gown (radiology dept more)

A

2 ways to put arms/hands in sleeves of sterile gown by self

26
Q

gloving performed after gowning

use closed method or open method

A

sterile gloving self

27
Q

fingers covered by gown and pick up gloves

right handed…use left hand to pick up glove

place glove on hand with palm down and fingers facing you

fingers grasp bottom of cuff and assistant hand pulls glove over hand to be gloved

A

closed method (hands in gown)

28
Q

opposite hand picks up glove

careful not to touch outside surface of glove

dominant hand gets gloved first

sterile glove hand picks up the other glove by reaching under cuff

sterile glove on first must touch only the outer surface and sterile surfaces

A

open method (hands out of gown)

29
Q

sterile person picks up gown

outside facing sterile person

circular person (non-sterile) fastens it

pullcuff over hands careful not to touch sterile gloves to hands

A

gowning another

30
Q

if in doubt consider it unsterile

field must be watched continuously

set up for procedure close to time of procedure

below waist and table is unsterile

arms and front of gown are sterile

sterile people pass each other back-to-back

unsterile people don’t reach above or over sterile field

if wet then package unsterile but can redrape

gloves kept in sight and above waist level

A

principles of sterile technique

Q

done for upper airway obstructions

sterile technique used

patient communicates with yes/no, hand signals, sign language

treat with Maslows hierarchy of needs

A

tracheostomies

32
Q

do not touch unless using sterile technique

nurse or respiratory therapist suctions

use ambu-bag if you suction (5-10 breaths)

test catheter

insert until resistence met then withdraw 1 cm

apply suction intermittently while withdrawing in rotating motion

never suction longer than 15 seconds

asses using auscultation

A

tracheostomies

33
Q

internal body sounds heard with stethoscope

listen for clear breath sounds

A

auscultation

34
Q

used for atelectasis (collapsedlung), pneumothorax, thoracotomy, open heart surgery

tube into pleural cavity to remove fluid, blood, air

A

chest tubes

35
Q

collection chamber

water seal chamber to prevent air from entering chest

2nd water chamber to control amount of suction

lower than patients chest

report if drainage is excessive (100cc per hour) or fluid color changes

A

chest tube drainage system

36
Q

straight

indwelling (remains in place)

A

types of urinary catheters

39
Q

plastic (short term)

latex (2-3 weeks)

polyvinyl (4-6 weeks)

silicone (2-3 months)

A

types of catheters based upon duration

40

collection bag below bladder (prevent reflux and infection)

don’t drag bag on floor

cut opening to drain sterile water before trying to remove (clamp/reclamp)

don’t entangle

A

urinary catheters things to watch for

41
Q

lithotomy position (supine, knees bent, genitalia exposed)

sterile drape under female

sterile drape under penis male

test balloon with sterile water

lubricate tip

expose the urinary meatus with non-dominant hand (no longer sterile)

clean urinary meatus with forceps, cotton balls, antiseptic

insert .5 inches women

insert 6-8 inches men

fill balloon when in place

A

urinary catheter insertion

42
Q

use gloves

wash hands

provide privacy

get consent

basin under valve

cut tip of balloon valve, drain

remove

get help if resistence when removed

A

removing urinary catheter

43
Q

radiography of urethra and bladder before, during and after voiding

A

voiding cystourethrograms

44
Q

suprapubic (closed drainage system above pubis; obgyn surgeries)

condom (males; incontinence)

A

other types of catheters

45
Q

regulates heart rate

prevents bradycardia (decreased heart rate)

involve an electrode to send impulses to contract heart

use subclavian vein

placed underneath skin on left side of patients pectoral fascia

A

pacemakers

46
Q

radiographer runs fluroscopy while physician positions guidewire

guidewire provides path for introducer sheath and pacing lead

use subclavian vein

lead is advanced to right atrium

sheath withdrawn and lead placed atapex of right ventricle

use C-arm

sterile technique

A

pacemaker inserting technique

47
