Q

-A protrusion of a section of the bowel into the inguinal ring.
üUsually occurs in boys (9:1)
-As the testes descend from the abdominal cavity into the scrotum late in fetal life, a fold of parietal peritoneum also descends, forming a tube from the abdomen to the scrotum.

A

Inguinal hernia

28
Q

Inguinal hernia
Manifestations:

A

ü Lump in the left or right groin.
ü In some instances, the hernia is apparent only on crying.
ü Inguinal hernias are painless. Pain at the site implies that the bowel has become incarcerated in the sac (Emergency)

29
Q

Inguinal hernia
Therapeutic Management:
Ø The bowel is returned to the abdominal cavity and retained there by sealing the inguinal ring.

Laparoscopic surgery

30

processes normally fuse between
weeks weeks __ and __ of intrauterine life.

A

5 and 8

population at 1 out of every 500
people.
-Small notch in the upper lip to total separation of the lip and facial structures up into the floor of the nose, with even the upper teeth and gingiva absent.
-May be unilateral or bilateral.

A

Cleft lip

33
Q

Nose generally appears flattened
because the incomplete fusion of
the upper lip has allowed it to expand in a horizontal dimension.

A

Cleft lip

34
Q

Cleft lip
Factors:

A

-Transmission of multiple genes aided by teratogenic factors
present during weeks 5 to 8 of intrauterine life, such as a viral
infection, certain seizure medicines such as phenytoin,
maternal smoking or binge drinking, hyperthermia, stress, and maternal obesity.
-Folic acid deficiency may be associated with incomplete
anterior midline closures.
-Genetic influence

35
Q

A

Cleft palate

A

Cleft palate

38
Q

Orofacial clefts:
Therapeutic Management:
___________: Cleft lip can be
repaired surgically shortly
thereafter, often at the time
of the initial hospital stay or
between 2 and 12 weeks of age
- Early repair also helps infants
experience the pleasure of
sucking as soon as possible.

A

Cheiloplasty

39
Q

***If the surgical repair for a cleft lip will be done immediately, the mother will be able to breastfeed as early as 7 to 10 days after surgery

A

4 to 6

40
Q

Palatoplasty
Malek

42
Q

After surgical repair, about ___% of children affected by cleft palate progress to develop normal speech, yet referral to speech therapy early in infancy should always occur to ensure successful speech development

A

80

43
Q

Nursing Considerations:
Cleft lip:

A
  • support in an upright position and feed the infant gently using a soft bottle and a commercial cleft lip nipple or a spoon.
    -If there is difficulty with latching, a nipple shield can be suggested to help form a tighter seal at the breast.
    -Review with the mother how to pump or manually express
    breast milk to maintain a milk supply prior to surgical correction and after, if needed.
  • Children need follow-up to detect if hearing or speech
    difficulty occurs; because the angle of the eustachian tube
    may be changed in surgery, a child may develop more ear
    infections than usual, possibly leading to some hearing impairment.
44
Q

Nursing Considerations:
Cleft palate: Surgery

A
  • If surgery will be delayed beyond 6 months of age or the time when solid food would usually be
    introduced, teach parents to be
    certain any food they offer is soft (liquid) because particles of coarse food could invade the nasopharynx and be a cause of aspiration.
  • Post-operative
    ØInfant is kept on NPO for 4 hours and then introduced to liquids such as plain water.
    ØNo tension is placed on a lip suture line because this helps keep the sutures from pulling apart and leaving a large scar.
    ØAfter palate surgery, only liquids are generally given the first 3 or
    4 days, and then a soft diet is followed until healing is complete.
  • When children begin to eat soft food: Don’t use a spoon because
    spoons can invariably be pushed against the roof of their mouth
    and possibly disrupt sutures.
    Be certain milk is not included in the first fluids offered because milk curds tend to adhere to the suture line and so are difficult to remove.
  • Clean suture line with sterile saline with sterile cotton-tipped applicators after every feeding or whenever the normal serum that forms on suture lines
    -After a feeding, always offer the sip of clear water to rinse the suture line
    -Prudent twice-daily gum and teeth brushing with an as are biyearly dental visits for monitoring
    -Position patient in side lying position to allow secretions
    to drain.
    -Nothing hard or sharp must come in contact with a recent cleft suture line (toys, straw, toothbrush, etc.)
45
Q

-A paroxysmal abdominal pain that generally occurs in infants under 3 months of age and is difficult to console.
-It is a common condition and is estimated to affect up to 1 in 5 infants during their first few
months.

A

Colic

46
Q

Colic
Marked by:

A

ü Loud, intense crying.
ü Infants pull their legs up against their abdomen
ü Face become red and flushed
ü Fists clench
ü Abdomens become tense
ü If offered a bottle, an infant will suck vigorously for a few minutes as if starved and then stop as another wave of intestinal pain occurs.

47
Q

Infantile Colic: _________ _______ (Rule of 3’s)

A

Wessel criteria

48
Q

Colic
Nursing considerations:

A

ü Thorough history: An intestinal obstruction or infection can mimic an attack of colic.
ü If the infant is bottle fed, ask about the type of formula used, how it is prepared, and if parents
hold the baby upright and burp the infant adequately after feeding.
ü For a breastfed baby, ask about the mother’s diet (Is she avoiding “gassy” food such as cabbage?).
üBoth breastfed and formula-fed infants may feel more comfortable with small, frequent
feedings to prevent distention and discomfort.
üOffering a pacifier can be comforting.
üPromoting comfort: Ex. Playing a music box that simulates the sound of a heartbeat are often reported as being helpful.
ü Caution parents to check with their primary care provider before using herbs or home remedies such as star anise to be certain what they have heard to be effective is safe for infants.
ü An infant cries and the parents may become tense and unsure of themselves. An infant then senses the tension and develops more colic.

49
Q

A sudden unexplained death in infancy younger than 1 year of
age. The peak age of incidence is 2 to 4 months of age.

A

Sudden infant death syndrome (SIDS)

50
Q

Sudden infant death syndrome (SIDS)
üTypically, affected infants are well nourished.
üAfter being put to bed at night or for a nap, the infant is then found dead a few hours later.
Infants who die this way do not appear to make any sound as they die, which indicates
they die with _____________.

A

laryngospasm

51
Q

Sudden infant death syndrome (SIDS)
Tends to occur at a higher than usual rate in (factors):

A

üInfants of adolescent mothers
üInfants of closely spaced pregnancies
üUnderweight and preterm infants
üEconomically disadvantaged
üNarcotic-dependent mothers

52
Q

Sudden infant death syndrome (SIDS)
üCause of SIDS is unknown
üIn addition to prolonged but
unexplained apnea, other
possible contributing factors
include:

A

• Sleeping prone rather than supine
• Viral respiratory or botulism infection
• Exposure to secondary smoke
• Pulmonary edema
• Brainstem abnormalities
• Heart rate abnormalities
• Decreased arousal responses
• Possible lack of surfactant in alveoli
• Sleeping in a room without moving air currents (the infant rebreathes expired carbon dioxide)

53
Q

Sudden infant death syndrome (SIDS)
Recommendations:

A

üPut newborns to sleep on their back: the incidence of SIDS has
declined almost 50% to 60%.
üUse of a firm sleep surface. Caution parents not to place pillows in an infant’s crib.
üBreastfeeding
üRoom sharing without bed sharing
üRoutine immunizations
üMany infants enjoy sucking on a pacifier to help them fall asleep.
üAvoidance of soft bedding, overheating, and exposure to tobacco smoke , alcohol, and illicit drugs.

54
Q

After SIDS Nursing Considerations:

A

üParents have a difficult time accepting the death of any
child. Parents should be counseled by someone who is
trained in counseling at the time of the infant’s death.
üAutopsy reports should be given to parents as soon as
they are available.
üReassure parents the death was not their fault. They
need this assurance if they are to plan for other children

55
