Q

What is an education piece for patients in terms of lab work?

A

Instruct patients on what their important blood counts are and to encourage them to track blood counts to understand their responses to treatment

25
Q

What is FN?

A

Febrile neutropenia - a medical emergency that has risks for sepsis and death

26
Q

What are risk factors for FN?

A

High dose chemotherapy, malnutrition, bone marrow disease, >65 years, advanced cancer, performance status, concurrent/prior radiation and liver or kidney dysfunction

27
Q

When are WBC levels the lowest for a patient receiving cell cycle specific antineoplastic?

A

7-10 days

28
Q

When are the WBC levels the lowest for a patient receiving cell cycle non-specific antineoplastic?

A

10-14 days

29
Q

What is an important education piece for patients to monitor for FN?

A

Teach them when they can expect to see neutorpenia, and to monitor for fever (either single temp of 38.3 or greater than 38 for >1 hr), as well as signs of infection

30
Q

Who are at highest risk for FN?

A

Leukemia, lymphoma and treatments that include high dose steroids

31
Q

Who are at highest risk for FN?

A

Leukemia, lymphoma and treatments that include high dose steroids

32
Q

What is the goal of treatment for FN?

A

Treat infection, optimize hydration, support immune function and prevent secondary infections

33
Q

What would you do before a pathogen has been isolated with FN?

A

Administer broad spectrum IV antibiotics and to schedule/ time multiple infusions

34
Q

What is G-CSF?

A

Granulocyte colony-stimulating factor

35
Q

What does G-CSF do?

A

Promote proliferation, differentiation and activation of cells to make granulocytes

36
Q

What is the indication of G-CSF?

A

Prevention and treatment of FN

37
Q

What is the indication of G-CSF?

A

Prevention and treatment of FN

38
Q

What is the most common side effect of G-CSF?

A

Bone pain

39
Q

How can you implement infection protection in the pediatric focus?

A

Hand hygiene, aseptic technique, assess for potential sites of infection, optimize nutrition, animal safety, protect from injury and no live vaccines

40
Q

What is leukemia?

A

Neoplastic proliferation of leukocytes in bone marrow that results in decreased WBC, RBC and PLT as well as weaken the bone which results in possible fractures​

41
Q

What are the 4 steps of chemotherapy for ALL?

A

1) Induction - 4 weeks until remission
2) CNS prophylaxis - prevent leukemic cells from entering CNS
3) Intensification - eradicate residual leukemic cells
4) Maintenance - maintain remission phase, lower dose treatment

42
Q

What are the 2 steps of chemotherapy for AML?

A

Induction and post-remission as maintenance is not recommended

43
Q

What are the 2 treatments involved in leukemia?

A

Cranial radiation +/- intrathecal chemotherapy and radiationto testicles in case of spread

44
Q

What is an important consideration for treating lymphoma?

A

Consider the radiation field, what the dose is, amount of time, what tissue is involved and what shielding is required

45
Q

What is an important consideration for treating lymphoma?

A

Consider the radiation field, what the dose is, amount of time, what tissue is involved and what shielding is required

46
Q

What are methods of supportive care for reducing the risk of bleeding with leukemia?

A

Ensure blood bank has up-to-date record of type and cross, have transfusion history available, CVC for access to blood and CBC with differential

47
Q

What are some bleeding precautions to be mindful of for a patient with leukemia?

A

Assess for blood in urine and stool, assess for changes in petechiae, bruising, epistaxis, don’t give IM, avoid rectal suppositories, fall prevention, stool softeners and laxatives to avoid constipation

48
Q

What is mucositis?

A

Painful inflammation and ulceration of the mucosal lining of the GI tract that is common with chemotherapy. It affects ability to eat and can be painful. It can be dose-limiting

49
Q

What are some interventions for mucositis?

A

Avoid alcohol based mouth rinse, use toothettes, frequent mouth rinse with sodium bicarbonate, soft liquid foods high in calories and protein, encourage oral fluid intake, schedule analgesics before meals, keep lips moist, swabs for bacteria, antibiotics as prescribed, dietary supplements and not using topical anesthetics for children

50
Q

Why don’t you use topical anesthetics for children?

A

With children, do not use topical analgesics because it can be a choking hazard as you numb the mouth and they may aspirate

51
Q

What is tumor lysis?

A

An oncologic emergency that is a metabolic imbalance that occurs because of rapid lysis of malignant cells

52
Q

What major complications does tumor lysis have?

A

Fatal renal, cardiac and neurologic complications

53
Q

What is tumor lysis syndrome?

A

Cell kill leading to dumping of cellular contents into bloodstream. There’s increased K, phosphate, uric acid and Ca that if the kidneys cannot excrete, it can be life-threatening.

54
Q

What is an important diagnostic test for tumor lysis syndrome?

A

Urine pH, serum potassium, phosphate, calcium and BUN

55
Q

What are the signs of tumor lysis syndrome?

A

N/V, diarrhea, muscle weakness, cramping, convulsions and cardiac arrest

56
Q

How can you prevent tumor lysis syndrome?

A

Pre-chemo hydration 24-48 hours before and continue 72 hours after treatment

57
Q

What 3 medications would you administer for tumor lysis syndrome as preventative measures?

A

1) Diuretics to promote excretion of phosphate and uric acid
2) Allopurinol to prevent uric acid formation
3) Sodium bicarbonate to keep urine pH alkaline and prevent uric acid from crystallizing

58
Q

What 3 medications would you administer for tumor lysis syndrome as preventative measures?

A

1) Diuretics to promote excretion of phosphate and uric acid
2) Allopurinol to prevent uric acid formation
3) Sodium bicarbonate to keep urine pH alkaline and prevent uric acid from crystallizing

59
Q

How would you treat a patient with tumor lysis syndrome that has onset?

A

Diuretics to prevent fluid overload, kayexlate to bind with potassium, insulin-glucose therapy to shift potassium back into ICF, calcium gluconate to correct hypocalcemia and dialysis as last resort
