Q

Why do infants lose a greater proportion of fluid daily? What does this put them at risk for?

A

Infants and toddlers < 2 have increased body surface area (more skin compared to the rest of their bodies)
Greater loss through lungs than adults due to faster respiratory rate.
Also infants need more water due to their high metabolism.
Risk for dehydration

Q

What organs are responsible in restoring and maintaining a balance in fluids & electrolytes?

A

Liver: Synthesizes proteins (hydrogen ions)
Kidneys: Excrete and reabsorb ions, water,
Skin: Insensible water loss
Lungs: Secrete CO2 (hydrogen ions)

Q

Why are children < 2 years of age at risk for dehydration?

A

Children’s kidneys are immature and do not retain water as well.
Body surface area greater (more water loss through skin)
Higher metabolism rate uses more water
Faster respiratory rate results in more water loss from lungs

Q

Explain the pathophysiology behind DM type

A

The theory is that a virus triggers antibodies that destroy the Beta cells in the pancreas that manufacture and secrete insulin. Insulin is necessary to allow water and glucose into the body cells for energy. When a child eats, a burst of insulin is release from the pancreas to aid in utilizing carbohydrates ingested.

Q

Congenital heart defects are categorized by

A

pathophysiology
and hemodynamics rather than by the presence of cyanosis.

88
Q

CHD that increase pulm blood flow

A
  • Blood flows from left to right side of heart due to higher pressure on left side of heart
  • Size of defect and amount of blood flow determine how quickly pulmonary HTN &/or CHF will develop
  • The increase in blood flow to lungs = pulmonary vascular resistance which leads to pulmonary hypertension
    INC pulm pressure result =
  • Tachypnea, tachycardia, ↑ metabolic rate, murmur
  • FTT due to poor intake.
  • CHF: Dyspnea, increased efforts of breathing, periorbital edema, peripheral edema, hepatomegaly
  • Frequent respiratory infections

types:
* Patent Ductus Arteriosus (PDA)
* Atrial Septal Defect (ASD)
* Ventricular Septal Defect (VSD)
* Atrioventricular Canal (Endocardial Cushion) Defect (AV Canal)

89
Q

CHD that sec pulm flow ‘cyanosis’

A
  • Pulmonic stenosis (valve) : Artery narrowed. Prevents blood going to lungs, backs up (edema) Corrected with balloon cath
  • Pulmonic atresia: Artery blocked. No blood flow to lung = cyanotic at birth. Alternate pathway created.
  • Tetralogy of Fallot (TOF) – TET or cyanotic spell: toddlers squat to increase blood flow to lungs
  • Pulm. Stenosis: None to CHF & chest pain
  • Pum. Atresia: Cyanosis at birth, usually has VSD
  • TOF: Hypoxic and cyanotic at birth. Cyanosis with feeding/crying. Squats to increase blood flower to the heart.
  • -Pulmonic stenosis
    -R ventricular hypertrophy
    -VSD (and sometimes ASD)
    -Overriding aorta
90
Q

CHD that obstruct systemic circulation

A
  • Aortic Stenosis
  • Coarctation of the Aorta: Allows increase blood to upper extremities (HTN and bounding pulses in upper arms) and decreases blood flow to legs.
  • HLHS (Hypoplastic Left Heart Syndrome)
91
Q

nursing care after cardiac cath

A
  • Check for the following during the first 24 hours after catheterization:
  • Encourage fluids to help flush the dye out of the body and to prevent dehydration (I & O)
  • Allow quiet play such as games, puzzles, and videos for the first 24 hours after the procedure
92
Q

After cardiac surgery, the child will

A

stay in ICU until stable. The ICU nurses will monitor vital signs, telemetry, behavior, LOC, respiratory status, I & O, hydration, and the incision for bleeding.

93
Q

tetrology of fallot

A

group of CHD that can cause a child to have “tet” or “blue” spells. When this happens, the child will squat to decrease blood return to the heart and increase systemic vascular resistance. The nurse can position an infant to achieve this same effect

94
Q

coarctation of the aorta will cause

A

pulses and blood pressures in the arms to be stronger than those in the legs.

95
Q

what must stay open after birth

97
Q

The early symptom of CHF are subtle in children:

A

– Fatigue, poor feeder, poor wt gain, edema

98
Q

A

n/v

Projectile vomiting EMESIS IS NOT BILIUS,

105
Q

107
Q

Gastroschisis and Omphaloceles
Explain the differences in these two conditions

A
  • Omphalocele: Covered by peritoneum & amniotic membrane – gastroschisis is not covered
