Peds Exam 2 Flashcards
What is the purpose of the duodenum?
where digestion takes place
What are the 2 enzymes that aid in digestion?
amylase (saliva, digests carbs)
lipase (enhances fat absorption)
trypsin (breaks down protein into polypeptides and some amino acids)
What are some differences in A&P in the GI system?
GI is immature at birth
Liver function is immature at birth and for next few weeks
GI structure becomes more mature in life in second yr
What is the function of the stomach?
secretes hydrochloric acid and digestive enzymes to break down fats (gastric lipase) and proteins (pepsin)- little absorption
What is the function of the small intestine?
digestion is completed here by pancreatic enzymes, bile, and small intestine enzymes
What is the function of the large intestine?
water absorption
What is the function of the liver?
bile production, detoxification, glycogen storage and breakdown, vitamin storage
What is the function of the gallbladder?
stores bile
What are subjective items to ask about in the GI assessment?
lifestyle and family factors diet elimination patterns mental status auscultation percussion and palpation Labs
What are some of the physiologic differences of pediatric patients?
minimal saliva decreased stomach capacity reverse peristalsis increased gastric emptying time large intestine is relatively short (=decreased water absorption, stools softer with greater water loss during diarrhea meaning they are at a higher risk of dehydration)
What are the important numeric values we need to know for stomach capacity of pediatric patients?
newborn - 10-20ml
1 yr - 210-360ml
adolescent - 1500ml
What is a cleft lip and cleft palate?
congenital malformation (failure of maxillary processes to fuse) occurring during weeks 6-12 gestation varying degrees of severity most common craniofacial deformities overall in US multifactoral causes
What is the first sign of a possible cleft lip/palate?
formula coming from the nose
How do you treat a cleft palate/lip?
surgical correction (early correction to stimulate pleasure when sucking)
lip repair usually by 12 weeks
palate repair usually by 6-24 mo to maximize speech
What are some complications of cleft lip/palate?
cosmetic speech and hearing feeding orthodontic otolaryngology
Explain a cleft lip
opening between the nose and lip
apparent at birth
should be documented during a newborn assessment
assess a child’s ability to suck and swallow
cleft lip repair is done in first month of life
special feeding techniques is surgery is delayed
What is some pre-operative nursing care for a cleft lip/palate?
feeding
facilitate bonding
growth and monitoring
logan bar (protects surgical repair)
How should feeding be done on a cleft lip/palate?
upright position (to prevent aspiration)
breastfeeding if possible
haberman nipple
frequent burping
What are some post-operative aspects of cleft lip/palate?
restraint
feeding
suture care
referrals
Explain the post-operative aspects of cleft lip/palate regarding restraints?
“no,no” for at least 6-8 days, longer with palate repair, remove one at a time every two hours for 15min, for babies– swaddling is perfect
Explain the post-operative aspects of cleft lip/palate regarding feeding?
no straws, pacifiers, spoons, fingers by mouth for 7-10 days, use shorter nipple, can feed with side of spoon for older children, advance diet as tolerated
Explain the post-operative aspects of cleft lip/palate regarding suture care?
lip protective device (Logan Bar) to prevent tension of suture site
no brushing for 1-2 weeks, clean suture line with water after each feed
do not place on stomach
no oral temps, no tongue depressants
What is some nursing management for cleft lip/palate ?
prevent injury to the suture line
promote adequate nutrition
encourage infant-parent bonding
providing emotional support
Explain esophageal atresia and tracheoesophageal fistula?
they are congenital malformations in which the esophagus terminates before it reaches the stomach and or a fistula is present that forms an unnatural connection with the trachea
foregut fails to lengthen, separate and fuse into 2 parallel tubes (at 4-5 weeks gestation)
assc with maternal polyhydraminos (fetus can not swallow and absorb amniotic fluid in utero)
What are the 3 C’s of EA and TF?
coughing, choking, cyanosis
What are manifestations of EA/TF?
coughing, choking, cyanosis
excessive oral secretions
respiratory distress
NG tube cannot be passed into the stomach
child needs NG tube to suction oral secretions which might land in a blind pouch
What are some nursing management techniques of TEF?
initiate NPO
elevate HOB
monitor hydration status
assess and maintain orogastric tube/prevent aspiration
O2 and suctioning equipment readily available
What is a pyloric stenosis?
results from hypertrophy of circular muscle that surrounds pylorus causing obstruction of gastric emptying
What are some of the manifestations of pyloric stenosis?
projectile vomiting 30-60 min after feeding at about 2 weeks of age
movable, palpable, olive-shaped mass
dehydration with metabolic alkalosis
What is a big sign of pyloric stenosis?
Vomiting after feeding
What are some preoperative nursing interventions for pyloric stenosis?
Assess for dehydration and acid/base imbalance
examine/listen to abdomen
Is/Os
Oral care
TREAT DEHYDRATION AND ELECTROLYTE STATUS BEFORE SURGERY
What are some postoperative nursing interventions for pyloric stenosis?
feeding according to OR protocol
pedialyte normally 4-6 hours after then advancing to full strength breast milk or formula
teach parents the signs of problems post surgery
What is gastroschisis?
a congenital defect of the ventral abdominal wall, characterized by herniation of abdominal viscera outside the abdominal wall (usually to the right of the umbilicus)
the organs are not contained by a membrane
occurs in week 11 of gestation
multifactoral causes
What is omphalocele?
protrusion of abdominal contents through the abdominal wall at the function of the umbilical cord
may include intestines, stomach, liver
organs covered by a thin transparent layer of amnion
occurs at 11 weeks of gestation
multifactoral causes
How do you overall manage omphalocele and gastroschesis?
must return bowel to abdomen
if defect is large, will be done with silastic pouch or silo
TPN dependent
large potential for infection
What is the nursing management of newborn omphalocele and gastroschisis?
minimize fluid loss
protect the exposed abdomen contents from trauma/infection
postoperative care
surgical repair for both are done in stages
What is intussusception?
the invagination of one portion of the intestine into another causing obstruction – ischmia — puss – bleeding etc
most common cause of intestinal obstruction in children under the age of 2
S/s of intussusception
severe pain
lethargy
currant-jelly stools, gross blood (pussy, red, stool)
sudden onset of intermittent cramps or abdominal pain (paroxysml)
Manifestations of intussusception
sudden onset of pain, draw up their lets, vomit
currant jelly stools
sausage shaped abdominal mass that can be palpated
extreme paroxysmal pain
assess for shock
Treatment of intussusception
US guided saline, barium, air enema to reduce
no response? surgical emergency to avoid bowel necrosis
laparoscopy
(if burst - will feel better for a moment then go into hypovolemic shock)
What is malrotation/volvulus ?
twisting of intestine
obstruction of feces
occurs d/t intestinal malrotation

What is Meckle’s Diverticulum?
most common congenital malformation of GI tract
like a fecal duct
is a pouch on the lower part of the intestine that is present at birth
may contain tissue that is identical to tissue of stomach or pancreas (secreting stomach acid= pain)
What is an umbilical hernia?
protrusion or projection of an organ or a part of an organ through the muscle wall of the cavity that normally contains it
imperfect closure of the umbilical muscle ring
is reduceable and resolves by 3-4 yrs
surgery if s/sx of strangulation or increased protrusion
