Saunders Peds Flashcards
vaccines derived from MO’s or viruses; their virulence has been weakened as a result of passage through another host.
Attenuated vaccine
the sound made by forced expiration, which is the body’s attempt to improve oxygenation when hypoxemia is present
grunting
vaccines that contain killed MO’s
inactivated vaccines
a widening of the nares to enable an infant or child to take in oxygen; a serious indication of air hunger
nasal flaring
a form of acquired immunity that occurs artificially through injection or is acquired naturally as the result of antibody transfer through the placenta to a fetus or through colostrum to an infant; is not permanent and does not last as long as active immunity
passive immunity
pertaining to early symptoms that mark the onset of a disease
prodromal

shunt
Eczema (Atopic Dermatitis) major goals of management
the major goals of management are to relieve pruritus, lubricate the skin, reduce inflammation, and prevent or control secondary infections.
assessment of eczema
weeping, oozing, and crusting of lesions
Eczema interventions
avoid irritants (detergents, harsh soaps)
bath not more than once daily in tepid water
apply cool, wet compress
antihistamines and steriods
A child with an integumentary disorder needs to be monitored for signs of:
skin infection or systemic infection
Impetigo
a contagious bacterial infection of the skin caused by beta hemolytic strep or staph and occurs most commonly during hot, humid months: honey-colored crusts with ulcerated bases usually on face. institute contact isolotion
Why dont you use Lindane, an alternative product to kill scabies, in children younger than 2 years old?
risk of neurotoxicity and seizures; use permethrin instead
How do you apply permethrin?
apply at least 30 mins after bathing, massage into ALL skin surfaces (except eyes and mouth). leave on skin 8-14 hours, wash off, a repeat tx may be needed
What is parent teaching assoc with scabies?
tell parents to change infected linens DAILY, washed in hot water, dried in hot dryer, and ironed before reuse
Priority Nursing Actions: Major pediatric burn injury
stop the burning process (smother flames)
assess the ABC’s
resuscitation if not breathing
remove burned clothing and jewelry
cover wound with a clean cloth (prevents contamination, relieves pain, and prevents hypothermia)
transport the child to the ED (keep child warm during transport)
why do lower burn temps and shorter exposure to heat cause a more severe burn in a child vs adult?
children’s skin is thinner
Which burns require fluid resuscitation?
burns involving more than 10% of total body surface area require some form of fluid resuscitation in the first 24 hours bc of the fluid shifts that occur as a result of the injury; cystalloids first, then colloids (albumin, Plasma-Lyte, or FFP) are useful in maintaining plasma volume
Do you use the rule of 9’s when estmiating extent of burn in children?
NO! in a pediatric client, the extent of the burn is expressed as a percentage of the TBSA using age-related charts
How do you determine accuracy of fluid resuscitation r/t burn in pediatrics?
VS (esp HR), urine output, adequacy of cap filling, and sensorium status are assessed
assessment indicating scabies
fine, grayish red, threadlike lines
clusters of fluid filled vescicles
herpesvirus infection
situations that precipitate sickle cell crisis (where HbA is replaced with HbS)
fever, dehydration, emotional or physical stress
treating a sickle cell crisis
hydration, oxygen, pain management (analgesics around the clock-but NOT Demerol->seizures), and bed rest (pain cannot be controlled without adequate hydration), blood transfusions may be necessary
sickle cell vaso-occlusive crisis
caused by stasis of blood with clumping of cells in the microcirculation, ischemia, and infarction (fever, painful swelling of hands, feet, and joints, ABD pain)
sickle cell splenic sequestration
caused by pooling and clumping of blood in the spleen (profound anemia, hypovolemia, and shock)
sickle cell hyperhemolytic crisis
an accelerated rate of RBC destruction (anemia, jaundice, and reticulocytes)
sickle cell aplastic crisis
caused by diminished production and increased destruction of RBC’s, triggered by viral infection or depletion of folic acid (profound anemia and pallor)
iron deficiency anemia
commonly results from blood loss, increased metabolic demands, syndromes or GI malabsorption, and dietary inadequacy (pallor, weakness/fatigue, Low H&H, RBCs are microcytic and hypochromic
how do you administer Iron IM?
using ztrack method
when do you take oral iron supplements?
between meals for max absorption with Vit C
aplastic anemia
deficiency of circulating erythrocytes and all other formed elements of blood (pancytopenia), resulting from the arrested development of cells within the bone marrow. (caused by exposure to myelotoxic agents, viruses, infection, autoimmune d/o’s, and allergic states); diagnosis by bone marrow aspiration-immunosuppressive therapy and bone marrow transplant (petechiae, purpura, bleeding, pallor, weakness, tachycardia, and fatigue)
increased tendency to bleed from mucous membranes
von Willebrand’s disease (and includes excessive menstrual bleeding)
Beta Thalassemia Major
most common in mediterraneans, italians, and greeks
frontal bossing, maxillary prominence, wide-set eyes and flattened nose, greenish yellow skin tone, hepatosplenomegaly, microcytic, hypochromic RBCs
leukemia assessment
infiltration of the bone marrow by malignant cells causes fever, pallor, fatigue, anorexia, hemorrhage (usually petechiae), and bone/joint pain, pathological fractures can occur as a result of bone marrow invasion with leukemic cells; signs of infection occur as a result of neutropenia
How does leukemia affect CNS?
IICP
macewen’s sign
cracked pot sound on percussion indicating IICP in infants
setting sun sign (eyes appear to look only downward, with the sclera prominent over the iris)
indicates IICP in infants
neutropenic precautions
aeseptic technique of course, but remember no fresh flowers, low bacteria foods (no fresh fruits or vegetables or undercooked meats) (Aspergillus and Pseudomonas aeruginosa may live in the soil of the living plants)
chemotherapy
monitor for severe bone marrow suppression, during the period of greatest bone marrow suppression (the nadir), blood cell counts are extremely low.
bleeding precautions: how long do you apply pressure to a needle stick site?
at least 10 mins if on bleeding precautions
Hodgkin’s Disease
often metastasizes to nonnodal or extralymphatic sites, especially the spleen, liver, bone marrow, lungs, and mediastinum
characterized by Reed-Sternberg cells noted in a lymph node biospy
Hodgkin’s Disease: prognosis is excellent
pancytopenia
increases risk for infection, bleeding, and anemia (common with radiation)
most common intraabdominal and kidney tumor in childhood (peak incidence is 3 years old)
Wilm’s Tumor (Nephroblastoma)
Wilms Tumor assessment
swelling or mass within the abdomen that is firm, nontender, confined to one side, and is deep within the flank.
Hematuria, fever, and hypertension are clinical manifestations associated with Wilm’s Tumor
why do we see hypertension with wilms tumor?
tumor releases excess renin
Precautions for Wilm’s Tumor
Place sign over bed DO NOT PALPATE ABDOMEN!!! measure abdominal girth at least once daily. Rupture of the tumor can cause the cancer cells to spread throughout the abdomen, lymph system, and bloodstream
neuroblastoma in general
often before age 10. Most presenting signs are caused by the tumor compressing adjacent normal tissue and organs. Neuroblastoma is a tumor that originates from the embryonic neural crest cells that normally give rise to the adrenal medulla and the sympathetic ganglion
Neuroblastoma prognosis
prognosis is poor bc of the frequency of invasiveness of the tumor, and because in most cases a diagnosis is not made until after metastasis has occurred.
neuroblastoma assessment
firm, nontender irregular mass in the abd that crosses midline.
Osteosarcoma
most common bone cancer in children and is usually found on the metaphysis of long bones, esp in the LE (most tumors in the femur) Peak age of incidence is 10-25 years.
osteosarcoma assessment
local pain that is often relieved by flexed position (pain is often attributed to growing pains)
palpable mass
limping if weight-bearing limb is affected
progressive limited ROM
child may be unable to hold heavy objects bc of their weight and resultant pain in the affected extremity
pathological Fx often occur at the tumor site
sudden fixed dilated pupils (or sluggish or unequal)
emergency! report immediately-may indicate IICP and potential brainstem herniation
lack of response to painful stimuli
report immediately
headache worse upon awakening but gets better throughout the day vomiting unrelated to feeding ataxia seizures behavioral changes clumsiness, awkward gait or diff walking diplopia facial weakness
potential brain tumor
opisthotonos, Kernig’s, Brudizinski’s signs
signs of meningitis
opisthotonos
Opisthotonos is a condition in which the body is held in an abnormal position. The person is usually rigid and arches the back, with the head thrown backward.
kernig’s sign
Severe stiffness of the hamstrings causes an inability to straighten the leg when the hip is flexed to 90 degrees.
brudizinski’s sign
Severe neck stiffness causes a patient’s hips and knees to flex when the neck is flexed.
Phenylketonuria
a genetic disorder that results in CNS damage from toxic levels of phenylalanine in the blood (>20 mg/dL when norms are 1.2-3.4 mg/dL). All 50 states require routine screening of all newborns, and the infant should have fed before specimen collection.
If high, restrict protein and aspartame
monitor physical, neuro, and intellectual development
Type 1 DM
destruction of pancreatic beta cells, which produce insulin, resulting in an absolute insulin deficiency
polydipsia, polyuria, polyphagia, blurred vision, weakness, weight loss, syncope
hyperglycemia
hyperglycemia progressing to metabilic acidosis
DKA
manifestations of DKA
hyperglycemia, kussmaul’s respirations, fruity breath, increasing lethargy, decreasing LOC
deep, rapid, labored breathing
kussmaul’s respirations
what is important to remember about administering potassium to a diabetic pt?
pt should be voiding adequately prior to administering potassium or hyperkalemia may occur
vomiting and diarrhea major concerns
major concerns are dehydration, loss of fluids and electrolytes, and development of metabolic alkalosis. Additional concerns are aspiration and the development of atelectasis and pneumonia.
projectile vomiting
consider pyloric stenosis or IICP
what are common pediatric causes of acute diarrhea?
acute infectious disorders of the GI tract, antibiotic therapy, rotavirus, and parasitic infection
What are causes of chronic diarrhea in peds?
malabsorption syndromes, ibd, immunodeficiencies, food intolerances, and nonspecific factors.
causes of cleft lip and cleft palate
hereditary and environmental factors-exposure to radiation or rubella virus, chromosome abnormalities, and teratogenic factors
What do you fix first? cleft lip or cleft palate, and when does this initial surgery typically occur?
Closure of a cleft lip defect precedes closures of the cleft palate and is usually performed by age 3 to 6 mos. Cleft palate repair is usually performed between 6 and 24 months of age to allow for the palatal changes that occur with normal growth; a cleft palate is closed as early as possible to facilitate speech development.
What is something to watch for in a child with cleft palate?
frequent otitis media resulting in hearing loss
Interventions associated with cleft lip/palate?
assess the ability to suck, swallow, handle normal secretions, and breathe without distress; keep suction equipment and a bulb syringe at bedside; teach parents ESSR method of feeding (enlarged nipple, stimulate sucking, swallow, and rest); AVOID ORAL SUCTION OR PLACING OBJECTS IN MOUTH (PACIFIER, TONGUE DEPRESSOR, ETC)
How do you position post op patient after cleft lip/palate repair?
NOT ON THE SIDE OF THE REPAIR; position on the back, upright to prevent airway obstruction; elbow restraints should be used to prevent the infant from injuring or traumatizing the surgical site (remove restraints q2h to assess skin integrity and circulation and ROM)
esophageal atresia or tracheoesophageal Fistula
the condition causes oral intake to enter the lungs or a large amount of air to enter the stomach, presenting a risk of coughing and choking; severe abdominal distention can occur; aspiration pneumonia and severe respiratory distress may develop, and death is likely to occur without surgical intervention
Treatment of esophageal atresia or tracheoesophageal fistula
maintain patent airway, prevent aspiration pneumonia (broad spectrum Abx may be prescribed), gastric or blind pouch decompression, supportive therapy, and surgical repair.
frothy saliva in the mouth and nose and excessive drooling
Three C’s (coughing, choking during feeding and unexplained cyanosis)
regurgitation and vomiting
abdominal distention
increased respiratory distress during and after feeding
esophageal atresia or tracheoesophageal fistula
What is important to know about a gastrostomy tube preop for esophageal atresia or tracheoesophageal fistula
If a gastrosomy tube is inserted, it may be left open to that air entering the stomach through the fistula may escape, minimizing regurgitation and distention
following correction of esophageal atresia or tracheoesophageal fistula, when can feeding begin?
before oral feedings and removal of the chest tube, prepare for an esophagogram as prescribed to check the integrity of the esophageal anastomosis
following correction of esophageal atresia or tracheoesophageal fistula, what do you teach parents?
instruct the parents to identify behaviors that indicate the need for suctioning, signs of respiratory distress, and signs of a constricted esophagus (poor feeding, dysphagia, drooling, coughing during feedings, regurgitated undigested food)
passive regurgitation or emesis, poor weight gain, irritability, hematemesis, heartburn, anemia from blood loss
assessment findings for GERD
assess amount and characterics of emesis
assess the relationship of vomiting to the itmes of feedings and infant activity
monitor breath sounds before and after feedings
assess for signs of aspiration, such as drooling, coughing or dyspnea after feeding
Place suction equipment at bedside
monitor intake and output
interventions for GERD
