MED SURG TEST 1

QuestionAnswer
preoperative(Pre-op) begins with patient decides to have surgery; consents; needs clearance before surgery--> includes labs, MR, etc.
intraoperative OR--> PACU
postoperative(post-op) PACU; goes up to unit or goes to recovery room and then home; this phase lasts until pt is healed; depends on type of surgery(inpt or outpt)
reasons for surgery diagnostic; curative; restorative; palliative; cosmetic
diagnostic reason for surgery biopsy, laparotomy
curative reason for surgery appendectomy
restorative reason for surgery total knee repair
palliative reason for surgery relieve symptoms
cosmetic reason for surgery rhinoplasty; usually done on outpt basis
causes of surgery-related stress fears- death; scared; pain; problem going under; being able to do anything on own; being disabled; how getting around; embarassment
surgical risk factors infection; rxn to anesthesia; death; wrong site surgery; do everything we can to reduce these
patient assessment before surgery/history and physical establish baseline
general early preop car: therapeutic communication client and fam teaching; pre-op, post-op(tubes, tubes, tubes); pre-op prep; make sure they understand the enviro of coming out of surgery
health teaching before surgery deep breathing and coughing; incentive spirometer; lower extremity exercises; positioning; pain meds; PCA pump/pain rating scales
lower extremity exercises surgery movement to prevent venous stasis/blood clots
positioning surgery understanding the position during surgery to understand soreness may occur after surgery
pain meds and surgery available afterwards; important to understand may not be given on regu basis; pain assessments will be done/evaluated; given PRN; pts need to be their own advocate
PCA(patient controlled analgesia) pump IV fluids; provide another level of control over pain; understand that it is individualized; family needs to know they should not be taking control only pt; not used with elderly, causes a lot of elderly pts to be confused
pre-op chart review ensure all documentation, preop procedures and orders are complete; pre-surg check list; check consent forms & others for complete; doc allergies, height and weight; ensure all labs/tests are on chart; doc/report abnormal results, special needs & concerns

pre op informed consent nurses role clarify facts presented by physician and address questions and concerns that the pt or family may have about surgery; not responsible for providing details about surgical procedure; can serve as witness to signature but not that the pt is informed;
informed consent implies that person has sufficient info to understand nature and reason for surgery; who will perform surgery and who will be present; options and risks assoc with each option; risks with procedure; potential outcomes and risk assoc with anesthesia
holding area prior to surgery never leave pt alone; greets pt; preop checklist; verify consent forms; ask pt what surg procedure is being done; assess emo status, gives support, answers ?; start IV/epidural; ID pt(2); fam ok here; if specific site, pt and nurse initial site
preop pt prep skin, prep, IVs, fluids; remove contacts, dentures, hearing aids, makeup, nail polish, jewlery(wedding band)
incentive spirometer purpose encourages pt to take deep breaths; promote complete lung expansion and to prevent pulm problems i.e. atelectasis; pneumo; uses visual feedback to encourage pt
incentive spirometer steps Seal lips tightly around mouthpiece; Inhale spontaneously; Hold breath for 3- 5 sec for effective lung expansion; AARC recs 5 to 10 breaths per session every hr while awake; Pain meds before helps pt achieve deep breathing by reducing pain, splinting
incentive spirometer goals can be set according to pts ability and type; Post-op capacity ½ to ¾ of pre op volume is acceptable due to post op pain
sequential compressions devices(SCDs) to promote venous return and prevent DVTs
preop labs CBC, PT, PTT, U/A,BMP; CXR, void; pre-op meds/VS; document
preop pt prep drugs(if ordered) antibiotics(on call); sedatives, histamine H2-receptor; antagonists; analgesics
the older surgical pt sensory impairments hypotension; hypothermia; hypoxemia r/t anasthesia; less adipose tissue; very cold in OR plus meds; pts on HTN meds--> could bottom out post op
the older surgical pt positioning complications r/t arthritis; decubiti/pressure ulcers; decreased subcu fat and reduced circ; twice as long to position, takes a team
drugs for care of the surgical pt neuromuscular blocking agents; anticholinergics; GI stimulants; sedatives/hypnotics; antianxiety agents; lots of drugs; cocktail during preop to prevent post op complications
nursing dx and interventions pre op deficient knowledge of surgery; fear; disturbed sleep pattern; ineffective coping; anticipatory grieving
sociocultural affiliation effect on surgical experience of client support; social network
team members not scrubbed circ nurse; anesthesiologist--> wear cover scrub jackets with long sleeves and protective eyewear; shoe covers
scrubbing up for surgery 3-5 min with broad spec ab; hands held higher than elbows; thoroughly drying; hands above wasit alcohol based; circ rn helps surgeon gown up; checks for tears; team wears sterile fluid resist gown, sterile gloves, eye protect or face shields
wrong patient errors JC 17%
wrong procedure JC 8%
wrong side JC 56%
other wrong site JC 19%
time out before surgery begings surgical team pauses to communicate about the specific pt and procedure; correct pt, med record, side/site, pt position, agreed procedure, right implants, correct equip, atbs; know advance directive

major safety concerns of the operative experience positioning; equipment; maintain asepsis; assisting in wound closure
geriatic positioning considerations dry skin, loss of tugor and elasticity; disposed to hematomas, handle carefully; poor nutritional status; osteoporosis; arthritic changes; limited ROM; venostasis; resp problems(thicker, less elastic alveoli; COPD, asthma)
obese positioning considerations HTN, CV disease, diabetes, decreased periph circ; strain on joints and ligaments; trendelenberg-increased venous return; risk of aspiration
malnourished positioning considerations more susceptible to infection; thin, poor skin tugor; susceptible to venostasis and thrombus formation; prone and trendelenburg not tolerated well
supine position foam headrest, foam donut, pillow; most common position; arms at sides, palms turned towards patient or on armboards: palms turned down; never beyond ROM or >90 degrees
trendelenburg position modification of supine; exposure of lower ab/pelvic cavity; arms on armboards or at sides; when pt is hypotensive--> want head down
trendelenburg contraindicated increased intracranial pressure; increased intraocular pressure(glaucoma); increased thoracic pressure
reverse trendelenburg position padded footboard; head up, feet down; arms on armboards or at sides; consider venous pooling
lithotomy position many potential problems; legs suspended, pt on back; consider back pain, joint replacements, ROM; arms with armboards <90 degrees; or tucked at sides--> WATCH fingers; prevent neuro damage; raise and lower legs simultaneously; can cause HTN
neurological damage with lithotomy position most common- femoral nerve from acute flexion; fem or obturator from personnel or instruments; saphenous, tibial, common perineal from the stirrups
fracture table position unaffected leg is raised; abducted and supported in a padded leg rest
general anesthesia loss of all sensation; reversible loss of consciousness induced by inhibiting neuronal impulses in several areas of the CNS; involves a single agent or a combo of agents; combo of inhalation and IV injection is best for older adults and high risk pts
regional anesthesia temporary interruption of nerve impulses to and from a specific body area
concious sedation client still has ability to retain pt airway and respond to commands
older pts and anesthesia general not always the best because of the effects it may have on the rest of the body; higher risk for resp problems; wake up slower; higher risk for atelctasis or pneumo; diminished or absent bowel sounds; cant feed until these are heard
anesthesia chosen based on pt's fears; health issues; previous response to anesthesia; type of surgery
purpose of anesthesia block nerve trans; promote muscle relaxation and suppress reflexes
complications from general anesthesia overdose; unrecognized hypoventilation; complications of specific anesthetic agents; complications of intubation
overdose of anesthetic if pts metabolism and drum elim slower than expected(liver or kidney); toxicity; important to obtain accurate history about the pts ht, wt, liver and kidney function to determine the anesthetic type and dose
unrecognized hypoventilation failure to exchange gases adequately may lead to cardiac arrest, perm brain damage and death
complications of intubation broken/injured teeth caps; swollen lip, vocal cord trauma; surgeon needs to be in OR during intub in case a trach is needed
malignant hyperthermia clinical manisfestations tachycardia; dysrhythmias; muscle rigidity; hypotension; tachypnea; skin mottling; cyanosis; elevated temp >111.2; potentially fatal
malignant hyperthermia genetics autosomal dominant; more common in young males; if known pts history pt can have a muscle biopsy to determine whether they are at risk; survival dependent on early diagnosis and actions of the surgical team
treatment of malignant hyperthermia possible with dantrolene, a skeletal muscle relaxant
spinal anesthesia non invansive; non generalized; wont have as many resp and GI issues as you have with generalized
neuro side effects/complications of gen anesthetic agents excessive sedation- delayed awakening
respiratory side effects/complications of gen anesthetic agents laryngospasm, hypoxia, hypercarbia
cardio side effects/complications of gen anesthetic agents hypotension; tachycardia; arrhythmias; fluid/electrolytes imbalances

nursing responsibilities of care of the intraoperative client nurse anesthetist observes for adverse effects intraoperatively; circ nurse runs the room; scrub nurse works with the dr
PACU(postanesthesia care unit) allows for ongoing evaluation and stabilization of pts to anticipate, prevent, and treat complications after surgery; circ nurse and anesthesia provider give PACU nurse a verbal hand off report
upon admission to PACU pt should be immediately placed in side lying position with head to side
admitted to PACU assess airway and gas exchanged; cont monitor spO2 >95%; RR <10= shock, acidosism pain; all wrpas/bandages assessed for bleeding, drainage and then hourly thereafter;

pre-op diet NPO
post op diet nutrition withheld until bowel sounds and no N/V; diet progresses slowly- ice chips, H2O, clear, full liquids, regular; by drs orders only
nutritional modifications to promote optimal wellness in surgical pts protein and calories for healing; low-fat, high fiber diets contraindicated; failure to use GI tract for > 4 or 5 days can result in atrophy of intestinal mucosa leading to risk for infection
nursing diagnosis for post-op pt acute pain; risk for infection; risk for imbalanced fluid volume; nausea; ineffective protection; delayed surgical recovery
impaired gas exchange interventions airway maintenance; positioning the pt in a side lying position or turning head to side to prevent aspiration; encourage breathing exercises; encourage mobilizations as soon as possible
impaired skin integrity interventions nursing assessment of the surgical area; dressings-first change usually done by surgeon; drains- provide exit route for air, blood, and bile as well as help prevent deep infections and abscess formation during healing
ineffective wound healing can be seen between 5th and 10th days after surgery; dehiscence or evisceration
