PEDS exam 2 Flashcards
who has higher SG children or infants
children
what percent of body weight is water in newborns? infants? children?
75, 65, 50
Why do infants lose a greater proportion of fluid daily? What does this put them at risk for?
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
What organs are responsible in restoring and maintaining a balance in fluids & electrolytes?
Liver: Synthesizes proteins (hydrogen ions)
Kidneys: Excrete and reabsorb ions, water,
Skin: Insensible water loss
Lungs: Secrete CO2 (hydrogen ions)
Why are children < 2 years of age at risk for dehydration?
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
Define and name 3 causes of dehydration in infants/children.
Vomiting and diarrhea #1
Nasogastric suctioning
Burns
Describe signs and symptoms a child with moderate dehydration would exhibit.
low BP, high HR, dark yellow urine, normal cap refill
Describe signs and symptoms a child with severe dehydration would exhibit.
very low BP, high HR, no urine, absent tears
Describe how the nurse can assist parents to rehydrate their child at home.
Use of pedialyte or oral rehydration - in very small sips very frequently
Which symptoms would alert the nurse to advise the parents to bring a child to the hospital immediately?
If the child has a change in level of consciousness, sunken fontanels, no wet diapers
What interventions are used by the nurse to determine a child’s hydration status?
Weigh the child daily, vital signs (orthostatic hypotension), Skin turgor LOC, Vital signs, urine & blood specimen collection, I & O (wet diapers), presence of tears
Maintenance fluids:
– Current weight in Kg
* Up to 10 kg 100 ml/kg/24 hour
* 11-20 kg 1000 ml + (50 ml/kg for weight above 10 kg)/24hour
* >20 kg 1500 ml + (20 ml/kg for weight above 20 kg)/24 hour
Replacement fluids
20ml per kg
- Metabolic alkalosis
Increase in bicarb (low potassium) decrease in acid
- Metabolic acidosis
Decrease in bicarb. (vomiting/diarrhea) Increase in other acids (poisonings)
- Respiratory alkalosis:
Loss of CO2.
Hyperventilation Respiratory acidosis
Too much CO2: Increase in intracranial pressure, cardiac arrythmias.
Name 3 nursing diagnoses related to burn care
- Risk for infection
- Deficient fluid volume
- Imbalanced nutrition
List collaborative management of a child with burns
Assess airway, especially with facial burns
Stop the burning process (cool, wet sheets)
Provide tetanus booster
Prevent infection
Provide for pain management
Which burns are the most concerning as far as infection risk?
Circumferential (Burn completely around limb)
Extensive eschar (contractures)
Facial (Possible lung damage)
Perineal (increased risk of infection due to stooling & ability to keep clean)
What are the clinical symptoms of GHD? what gland
ant pituitary - Short stature
Youthful features
Delayed bone, muscle, and secondary sex characteristics
What is the treatment for GHD? How long is it administered?
Growth hormone subQ injections daily or qod.
Until: Desired height is met; Bone age > 14 in girls and > 16 in boys
Describe nursing interventions that will meet the needs of these children.
Encourage well child exams to detect this condition early.
Patient and parent education regarding SQ injections,
Emotional support for the patient and family

Etiology of precocious puberty
pre activity of hypothalamus
tx of percocious puberty
lupron
What is the cause of this disease? DI
Deficiency of ADH (antidiuretic hormone) due to tumors of the posterior pituitary gland
Name the principle imbalance with a deficiency of ADH.
dehydration
Identify the main clinical symptoms of DI
Polydipsia and polyuria
Urine is dilute so low specific gravity
And serum Na is high
How is DI treated?
replacement ADH
Nursing Implications: for DI
weight daily and manage fluids
Explain the etiology of this condition. SIADH
, there is too much ADH causing water intoxificaiton or fluid overload without the sodium increase in the blood.
Identify the reasons for the symptoms of SIAHD.
The symptoms are the result of fluid overload:
CHF, crackles in the lungs, wt gain without edema, hypertension.
How does the nurse care for a child with SIADH?
Provide distraction when fluids are limited.
Administer medications and hypertonic saline IVs as ordered
Too little (Hypothyroidism) s/s
Constipation
Depression
Lethargy
Lowered BP and heart rate
Dry brittle hair
Weight gain
Irregular menses
Too much (Hyperthyroidism or Grave’s Disease) s.s
Diarrhea
Anxiety
Weight loss
High blood pressure and heart rate (tachy)
Tremor
Exophthalmia
Difficulty in attention or studying
Congenital hypothyroidism presents
shortly after birth causing severe cognitive problems and developmental delays if not recognized and treated.
Discuss the treatment of acquired hypothyroidism in children.
LIFELONG synthroid
How might a school-aged child’s hyperthyroidism affect his behavior in school?
Unable to sit still, anxiety, “hyper”, difficulty concentrating, falling asleep in class from exhaustion.
Name the cause of Cushing Syndrome.
pit gland tumor - too much steroids
List the symptoms of cushing syndrome:
Moon face
Weight gain (truncal)
Buffalo hump on back
Hyperglycemia
Hypertension
Poor wound healing
Since corticosteroids decrease inflammation, they can mask an infection until damage is done to organs
When a parent asks the nurse if the symptoms will go away after the medication wears off, what will the nurse respond?
The effects will go away after the steroids are stopped. The main thing is NOT to stop the steroids abruptly!
What nursing implications are there for steroid administration?
Take with food to avoid gastric irritation.
Take at the same time every day
Never stop abruptly! Call the provider if you have concerns.
Other names: Prednisone, prednisolone, hydrocortisone, corticosteroids, glucocorticosteroids, SoluMedrol (IV), cortisol
Congential adrenal hyperplasia
Missing an enzyme necessary to form cortisol or aldosterone
Describe nursing interventions when caring for a child with this disorder.
Describe nursing interventions when caring for a child with this disorder. CAH
steroids for life
Addison’s Disease
Autoimmune disease with deficient cortisol
Corticosteroid oral directions:
- Always give at same time every day (mornings preferred)
- Give with food to prevent GI upset
- Never skip doses
- Do not stop abruptly (must be tapered off)
- Alternate parental form of med must be available in case of stressful situations or unable to take po
Explain the pathophysiology behind DM type
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.
What happens without insulin?
Cell dehydration, ketone buildup, metabolic acidosis and death
Symptoms: DM
Polyuria, polydipsia, polyphagia (pees a lot, thirsty, and hungry)
Over time, weight loss
In children, enuresis may occur after toilet training complete
Treatment: DM
Basal insulin: Long acting insulin (glargine) that provides a baseline, small amount of constant insulin)
Bolus insulin: Rapid acting insulin (Humalog) that is given with dinner/snacks to allow use of carbs taken in.
Pumps are used often in children to provide insulin and the amount needed is programmed in.
