39
Q

What are some oncologic emergencies?

A
  1. Superior Vena Cava Syndrome
  2. Spinal Cord Compression
  3. Hypercalcemia
  4. Pericardial effusion/Cardiac tamponade
  5. Disseminated Intervascular Coagulation
  6. SIADH
40
Q

Describe the symptoms of superior vena cava syndrome

A

increasing dyspnea as well as increasing edema of the face and arms

41
Q

What happens during cardiac tamponade?

A

the pericardial sac of the heart has excess fluid/blood causing decreased pumping ability and a cardiac emergency

42
Q

What would be the intervention for a cardiac tamponade?

A

Aspirate fluid/blood from the pericardial sac

43
Q

Why does Superior Vena Cava Syndrome occur?

A

The superior vena cava gets blocked by cancer causing fluid to backup which leads to increased edema

44
Q

What are the 3 D’s of Beck’s triad for a cardiac tamponade?

A
  1. Distant heart sounds
  2. Distended jugular veins
  3. Decreased arterial pressure
45
Q

What may radiation be used for and how may it be delivered?

A
  1. used alone or in combination with surgery, chemotherapy
  2. maybe either cure or symptom relief
  3. may be delivered by external beam, intraluminal radiation, and brachytherapy
46
Q

What is a side effect of radiation?

A

Burns: need to treat this side effect

47
Q

What are the nursing care concerns for oncology?

A
  1. infection
  2. skin integrity
  3. Nutrition
  4. Pain control
  5. Psychological adjustment (cure sometimes, relieve often, comfort always)
  6. body image
48
Q

Why can body image be an issue for oncology patients?

A

external scars from surgery and radiation burns change a patients body image

49
Q

If a patient is fearful/afraid what question should a nurse ask him about?

A

What is causing the most fear right now?

50
Q

What assessments should a nurse look for respiratory function?

A

51
Q

When assessing smoking history what questions should you ask?

A
  1. how many packs per day
  2. how many packs per year
  3. How many years of smoking
52

A

keep one on their front door, the fridge, and next to the bed

55
Q

What does chest percussion help with?

59
Q

If the ventilator is doing most of the work for the patient what should the nurse discuss with the family?

A

Discuss with the family what they want to do next. Take the patient off the ventilator or not

60
Q

Q

What are some nursing interventions to manage fatigue and activity intolerance?

A
  1. plan rest periods (cluster care)

63
Q

What are the nursing interventions to promote healthy grieving?

A
  1. spend time with the client and family
  2. Answer questions honestly
