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

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

LOW residue diet2.Provide information about post-op care and

stoma care3. Administer antibiotics 1 day prior

skin irritation and pulmo complication2. Assess the abdomen for return of

peristalsis

24H5.provide nutritional teachingLimit foods that cause gas-formation

and odorCabbage, beans, eggs, fish, peanutsLow-fiber diet in the early stage of

recovery

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?
