Peds Exam 1 Flashcards
Adults w Cancer
-usually not metastasized at diagnosis
-involves organs
-the primary cause is environmental exposures
-usually, a long latent period, could be up to 20 years
Kids with Cancer
-about 92% of cancer develops from primitive embroyal tissue
-involves tissues
-the cancer is usually metastasised at diagnosis
-short latent period
Early s/s of pediatric cancer
-unexplained pallor
-loss of energy
-unusual mass, lump, or swelling
-sudden unexplained weight loss
-unexplained fever that doesn’t go away
-easy bruising/ bleeding
-prolonged/ongoing pain in one or more areas of the body
-limping, refusal to bear weight
-frequent headaches, especially in the morning ( the headaches are associated with vomiting)
-vision changes
What is the most common type of cancer in children
leukemia
Leukemia s/s
-petechiae
-MSK pain
-fatigue
-weight loss
-pt may present with hyperleukocytosis
-50% of pt present w/ lymphadenopathy
-50% of patients have a fever
-50% of patients present with hepatomegaly/splenomegaly
children with trisomy 21 are at an increased risk for
leukemia
leukemia description
immature lymphoblasts replace normal cells in the bone marrow which leads to pancytopenia ( anemia, neutropenia, thrombocytopenia)
Hodgkin Lymphoma ( HL ) is most common in which age group
teens, young adults
what is the hallmark sign of Hodgkin lymphoma
presence of Reed-Sternberg B cells
Hodgkin lymphoma description
malignant cells proliferate in lymph tissues which lead to lymphadenopathy which then leads to compression of nearby structures which kills healthy cells and invades surrounding lymph tissue
Epstein-Barr virus infection is usually associated with
Hodgin Lymphoma
Hodgin Lymphoma s/s
-this pt usually have non-specific symptoms
-weight loss
-fever
-night sweats
-anorexia
-fatigue

Non-Hodgkin Lymphoma description
-all lymphomas except Hodgkin’s ( common in 48% of patients with primary immunodeficiencies)
-B and T lymphocytes mutate and increase rapidly in the DEEP tissues
-progression of symptoms occurs quickly
non-hodgkin lymphoma s/s
-pain
-lymphadenopathy
-abdominal mass
-mediastinal mass present may lead to superior vena cava syndrome since the mass is pressing into the vena cava
osteosarcoma description
most common malignancy of bone in children and adolescents
often occurs in long bones: distal femur, proximal tibia, proximal humerus
osteosarcoma s/s
-intermittent pain localized to tumor size
-tends to develop following an injury

Ewing Sarcoma description
most often in the long bones of the extremities ( predominantly the femur, tibia, fibula, and humerus) and bones of the pelvis
Ewing Sarcoma
-the trauma may incite symptoms
-intermittent pain that transitions to constant over weeks to months ( pain worsens overnight)
-there is usually edema and erythema over mass
Retinoblastoma

retinoblastoma s/s
-Leukocoria
-strabismus
-nystagmus
-if you take a picture with flash, you will be able to see the difference between the pupils
Neuroblastoma description
-tumor originates from the neural crest during fetal development
-can arise anywhere throughout the SNS, the adrenal gland is the most common location and then the abdomen follows

-pt needs a private room and to close the door
-frequent hand hygiene
-no rectal temps
-avoid invasive procedures
-no fresh fruits, veggies
-should be no plants in the room
Hematopoietic Stem Cell Transplant
-bone marrow transplant
autologous: child’s own stem cells are removed so the patient can undergo chemo and then the cells are restored after treatment
allogeneic: donor’s stem cells
Pre-transplant (HSCT)
-prophylactic ABX, antifungals, antivirals
-regular CHG bath
-give blood products PRN
-give G-CSF if ordered
Post-transplant (HSCT)
-prophylactics
-maculopapular rash
-the patient may need systemic steroids if GVHD occurs
-manage GI s/s
-bleeding and pancytopenia may occur
-give G-CSF PRN for autologous HSCT recipients
(filgrastim may be given IV or injection)

-ventilation
-surgery
-comfort measures
Neutropenic Enterocolitis (Typhlitis)
-life-threatening
-necrotizing enterocolitis
-occurs mainly in patients with blood cancers following the induction of chemo
-there is a disruption of intestinal mucosa which allows for opportunities pathogens to cause an infection and necrosis of the intestinal wall
s/s of neutropenic entercolitis
-abdominal pain
-nausea and vomiting
-anorexia
-blood emesis

Tumor Lysis Syndrome description
therapy which causes rapid lysis of tumor cells ( like chemo and radiation) which leads to intracellular contents releasing into systemic circulation

-AKI
s/s of tumor lysis syndrome
-diarrhea

Prevention of TLS
-give hypouricemic agents prophylactically and during chemo/radiation treatment
-IVFs at 2x maintenance
-frequent F and E monitoring
-limit Potassium intake, give glucose with insulin or calcium gluconate to decrease the risk of dysrhythmias
-aggressive hydration
When does the production of RBC begin?
8 weeks in utero
where is erythropoietin derived from
the liver in the fetus, but the kidneys take over after birth
what are the three types of hemoglobin present at birth
Adult ( Hgb A and A2)– present in utero and predominate around 2 months after birth
HbF: predominate at 8 weeks gestation ( decreases to 70% by birth and disappears by 6-12 months old)
Iron-deficiency anemia
-Fe deficiency is the most common nutritional disorder in the world, with increased prevalence in developing countries
-occurs when the body does not have enough iron to produce Hgb
risk factors for iron-deficiency anemia
-prematurity or LBW
-exposure to lead
-breast-feeding beyond 4 months without iron supplementation
-cow’s milk without adequate Iron intake
-low socioeconomic status
-recent immigration from a developing country
-use of meds that interfere with iron absorption ( like antacids)
assessment for iron-deficiency anemia
-inspect mucous membranes and skin pallor
-assess for spooning of nails
-auscultate for flow murmur
-assess for splenomegaly
Diagnosing iron-deficiency anemia (children 6 months to 5 years)
ferrtin is less than 15 mg/L
hemoglobin is less than 11g/dL ( 0.5 -5 YEARS)
diagnosing iron-deficiency anemia ( children 5 to 12 years)
ferritin is les than 15 mg/L
hemoglobin is less than 11.5 g/dL
s/s for iron-deficiency anemia
-growth retardation in chronic cases
-irritability
-HA
-weakness
-pallar
-fatigue
severe s/s:
-SOB
-dizziness
less common s/s:
-pica
-muscle weakness
-unsteady gait
-difficulty feeding
Nursing Interventions for Fe-deficiency anemia
-encourage breastfeeding moms to increase Fe+ intake
-if baby is formula fed, encourage Fe-fortified formula
-for kids under a year, limit cow’s milk to less than 24oz a day ( an excess amount can cause cow’s milk colitis)
-no NSAIDS, give them Tylenol
-begin iron supplementation beginning @ 4 months
Considerations for Iron supplementation
-inform parents that stool may be black
-constipation may occur but give laxatives and stool softners PRN
-it is recommended to give 3-6mg/kd/daily an hour before a meal to increase absorption
-iron drops can stain the teeth brown/orange so give older children a straw and put the drops behind the teeth of younger children
Heme sources
-beef
-chicken
-turkey
-tuna
-crab
-halibut
-pork, shrimp
Non-heme sources
-iron-fortified cereal/oatmeal

Sickle Cell Disease description
an autosomal recessive disorder
three most common types: HbSS ( most severe), HbSC, HBS beta thalassemia
hallmark s/s of sickle cell disease
-vaso-occlusive phenomena
-hemolytic anemia
how long do sickle cells last versus normal RBCS
20 days vs 120 days
things that can lead to a sickle cell crisis
-dehydration
-infection
-cold
-respiratory distress
-pain
Why are infants usually asymptomatic if they have sickle cell
Because the fetal hemoglobin is protecting them. When it wears off at 3-4 months, they may start to show symptoms
