Nursing AssessmentUtilize the ACS 7 Warning SignalsCAUTIONC- Change in bowel/bladder habitsA- A sore that does not healU- Unusual bleedingT- Thickening or lump in the breastI- IndigestionO- Obvious change in wartsN- Nagging cough and hoarseness
Nursing AssessmentWeight lossFrequent infectionSkin problemsPainHair LossFatigueDisturbance in body image/ depression
Nursing InterventionMAINTAIN TISSUE INTEGRITYHandle skin gentlyDo NOT rub affected areaLotion may be appliedWash skin only with SOAP and Water
Nursing InterventionMANAGEMENT OF STOMATITISUse soft-bristled toothbrush Oral rinses with saline gargles/ tap waterAvoid ALCOHOL-based rinses
Nursing InterventionMANAGEMENT OF ALOPECIA
Alopecia begins within 2 weeks of therapy
Regrowth within 8 weeks of terminationEncourage to acquire wig before hair loss
occursEncourage use of attractive scarves and
hatsProvide information that hair loss is
temporary BUT anticipate change in texture and color
Nursing InterventionPROMOTE NUTRITIONServe food in ways to make it appealingConsider patient’s preferencesProvide small frequent mealsAvoids giving fluids while eatingOral hygiene PRIOR to mealtimeVitamin supplements
Nursing InterventionRELIEVE PAINMild pain- NSAIDS
Moderate pain- Weak opiodsSevere pain- MorphineAdminister analgesics round the clock with
additional dose for breakthrough pain
Nursing InterventionDECREASE FATIGUEPlan daily activities to allow alternating
rest periodsLight exercise is encouragedSmall frequent meals
Nursing InterventionIMPROVE BODY IMAGETherapeutic communication is essentialEncourage independence in self-care and
decision makingOffer cosmetic material like make-up and
wigs
Nursing InterventionASSIST IN THE GRIEVING PROCESSSome cancers are curableGrieving can be due to loss of health,
income, sexuality, and body imageAnswer and clarify information about
cancer and treatment optionsIdentify resource peopleRefer to support groups
Nursing InterventionMANAGE COMPLICATION:
INFECTIONFever is the most important sign (38.3)Administer prescribed antibiotics X
2weeksMaintain aseptic technique Avoid exposure to crowds Avoid giving fresh fruits and veggieHandwashingAvoid frequent invasive procedures
Nursing InterventionMANAGE COMPLICATION: Septic shockMonitor VS, BP, tempAdminister IV antibioticsAdminister supplemental O2
Nursing InterventionMANAGE COMPLICATION: BleedingThrombocytopenia (<100,000) is the most
common cause <20, 000 spontaneous bleedingUse soft toothbrushUse electric razorAvoid frequent IM, IV, rectal and
catheterizationSoft foods and stool softeners
COLON CANCERRisk factors1. Increasing age2. Family history3. Previous colon CA or polyps4. History of IBD5. High fat, High protein, LOW fiber6. Breast Ca and Genital Ca

(temporary or permanent)
Colon cancerNURSING INTERVENTIONPre-Operative care1. Provide HIGH protein, HIGH calorie and
LOW residue diet2.Provide information about post-op care and
stoma care3. Administer antibiotics 1 day prior

and the morning of surgery5. NGT is inserted to prevent distention6. Monitor UO, F and E, Abdomen PE
Colon cancerNURSING INTERVENTIONPost-Operative care1. Monitor for complicationsLeakage from the site, prolapse of stoma,
skin irritation and pulmo complication2. Assess the abdomen for return of
peristalsis
Colon cancerNURSING INTERVENTIONPost-Operative care3. Assess wound dressing for bleeding4. Assist patient in ambulation after
24H5.provide nutritional teachingLimit foods that cause gas-formation
and odorCabbage, beans, eggs, fish, peanutsLow-fiber diet in the early stage of
recovery
Colon cancer
NURSING INTERVENTIONPost-Operative care6. Instruct to splint the incision and
administer pain meds before exercise7. The stoma is PINKISH to cherry
red, Slightly edematous with minimal pinkish drainage
8. Manage post-operative complication
Colon cancerNURSING INTERVENTION: COLOSTOMY
CAREColostomy begins to function 3-6 days after
surgeryThe drainage maybe soft/mushy or semi-solid
depending on the site
Colon cancerNURSING INTERVENTION: COLOSTOMY
CAREBEST time to do skin care is after showerApply tape to the sides of the pouch before
showerAssume a sitting or standing position in
changing the pouch
Colon cancerNURSING INTERVENTION: COLOSTOMY
CAREInstruct to GENTLY push the skin down and
the pouch pulling UPWash the peri-stomal area with soap and
waterCover the stoma while washing the peri-
stomal area

Discussion of
Palliative CareOncologic EmergenciesLung CancerMale & Female reproductive CancersBrain Tumors
Critical ThinkingScenario: A 49 y/o male has a 32 year
history of cigarette smoking. He often eats out with associates and typically eats red meat and potatoes. One of his associates is a 51 y/o female whose mother dies of breast cancer. She is 40lbs over her ideal weight because she likes to snack during the day. She is also a heavy coffee drinker because she is from Seattle.
Case Study 1R.T. is a 64-year-old man who comes to his primary care provider’s (PCP’s) offi ce for a
yearly examination. He initially reports having no new health problems; however, on further questioning, he admits to having developed some fatigue, abdominal bloating, and intermittent constipation. His nurse practitioner completes the examination, which includes a normal rectal exam with a stool positive for guaiac. Diagnostic studies include a CBC with differential, chem 14, and carcinoembryonic antigen (CEA). R.T. has not had a recent colonoscopy and is referred to a gastroenterologist for this procedure.
A 5-cm mass found in the sigmoid colon confirms a diagnosis of a polypof the colon. A referral
is made for surgery. The pathology report describes the tumor as stae 11, which meansthat the cancer has extended into the mucous layer of the colon. A metastatic work-up is
negative.
1. Identify 6 risk factors for colon cancer:2. Discuss the recommended screening procedures related to colon cancer.3. What warning sign did R.T. have?4. What would early signs be for colorectal cancer?5. What would late signs be?

6. After bowel prep, R.T. is admitted to the hospital for an exploratory laparotomy, small bowel resection and sigmoid colectomy. - What are five major complications for him?
7. After surgery, R.T. is admitted to the surgical intensive care unit (SICU) with a largeabdominal dressing. The nurse rolls R.T. side to side to remove the soiled surgical linen,and the dressing becomes saturated with a large amount of serosanguineous drainage.Would the drainage be expected after abdominal surgery? Explain.
Case Study 2You are a home health nurse who has been seeing P.C., who was diagnosed with lung
cancer approximately 1 year ago. Her provider recently informed her that her cancer is no longer treatable; the focus of her treatment will change from curative measures to symptom relief. She is confused and somewhat angry with her provider. She vaguely remembers the term palliative treatment when discussing her situation with her provider but doesn’t know what it means.
1. How would you describe palliative treatment?

She is confused and somewhat angry with her provider. She vaguely remembers the term palliative treatment when discussing her situation with her provider but doesn’t know what it means.
Case progress Note:P.C. confides that she always felt that she might not survive her illness, but has never formally
writtendown her wishes concerning what types of treatment she would or would not want. You advise
herto complete an advance directive and/or living will or to complete a medical durable power of
attorneyand/or a surrogate decision maker form. In current practice, it is very likely that a part of the
homehealth intake process will be completion of a Physicians Order on Life Sustaining Treatments
(POLST)Paradigm form.
2. What is the purpose of these documents?
Case Study 23. What health care decisions are considered in these documents?
4. How are advance directives and living wills formalized?
5. P.C. states she is confused and has mixed feelings about her health care wishes right now.
She asks, “If I fill out this form, can I change my mind down the road?” How should you
answer this question?
6. You inform P.C. that you will help with symptomatic control of her illness. What areas
will you focus on, and what question would you ask P.C.?
7. As P.C. becomes more frail and incoherent, what treatment will be given?
