Exam 3 Gastroenterology Flashcards
Gastroenterology (3)
Diarrhea
Celiac Disease
Acute Appendicitis
Diarrhea
- Acute diarrhea -> ___ cause of ___ children < __ yo
- Acute infectious diarrhea -> ___ of ___ organisms
1) The most common viral cause =
2) Bacterial causes (4)
3) Bacterial diarrhea looks more =
- most, illness, < 5
- Variety of causative
1) Rotavirus (however new oral vaccine has reduced incidence)
2) E.coli, Salmonella, Shigella, Campylobacter
3) Bloody
Dehydration occurs when =
= total output of fluid exceeds intake
Why are infants at more risk for insensible water loss? (4)
1) > body surface area
2) Basal Metabolic rate
3) Immature kidney function, cannot concentrate urine
4) Greater need for fluids to excrete solutes
Isotonic Dehydration =
Hypotonic Dehydration =
Hypertonic Dehydration =
= water and salt lost in equal amounts
= More electrolyte loss than water loss
= more water loss then electrolyte loss
Fluid Distribution
1) Intracellular Fluids (4)
2) Extracellular Fluids (3)
3) Interstitial fluid =
4) Intravascular fluid =
1) K+, Phosphate, Sulfate, Protein
2) Na, Cl, Bicarb (saline)
3) fluid between cells, outside of blood vessels
4) Plasma within vessels
During Illness
- First loss of fluid in ____ compartment
- Greater risk for dehydration and alterations in fluid and electrolytes bc?
- Extracellular
- infants/young children have greater proportion of extracellular fluid (40%) compared to our (20-30%)
Clinical manifestations of dehydration
1) Weight _____
2) _____ pulse
3) _____ BP
4) _____ peripheral circulation
5) _____ urinary output
6) ____ specific gravity
7) _____ skin turgor
8) ____ mucous membranes
9) _____ of tears
10) ____ fontanels
1) loss
2) rapid
3) decreased
4) decreased
5) decreased
6) increased
7) decreased/dry
8) absence
9) sunken
Severe Dehydration
1) Weight loss >/- ___% most accurate way to assess acute dehydration
2) Very increased Vitals (2)
3) _____ hypotension > ___ mmhg change can lead to ___
4) Behavior can range from ____ to _____
5) ____ to ____ thirst, ___ to ___ mucous membranes
6) __ tears, ___ eyes, ___ fontanels
7) m___, __ skin, Cap refill =
1) 10%
2) increased HR, Hyperpnea (deep, rapid)
3) Orthostatic, > 20 mmhg change can lead to shock
4) hyperirritable to lethargic
5) Moderate to intense, dry to parched
6) absent, sunken, sunken
7) cool, mottled, very delayed > 4 secs
First Choice Management for Dehydration is?*
Oral Rehydration Therapy - PEDIALYTE*
Why is ORT first choice?
- s____, ___ painful, less ____ than IV rehydration
- enhances and promotes reabsorption of (2)
- reduces v___, d___, ___ of illness
- safer, less, costly
- H20, Na
- vomiting, diarrhea, duration
ORT contains (4) electrolytes
- ____ mEq of sodium/L
- Given in ___ volumes: __-__ ml/kg q __-___ hrs
- Can give even if _____
Glucose, Na, Cl, K
- 75
- 50-100 ml, 3-4 hr
- vomiting (small amounts)
Dehydration magement
1) Observe for =
2) NO (2) why?
3) Reintroduction of foods should be? What type of foods to avoid? (3)
1) Urine output
2) Antimotility bc can cause ileus, Antibiotics bc is a virus
3) Slow, Gradual reintroduction of bland foods, Avoid sugary, spicy, fried foods
Hospital Management for Dehydration
- If ORT doesn’t work?
- Assessment of skin ___, m__ m___, f_____
- hospitalization for IV rehydration
- turgor, mucous membranes, fontanels
I/O's - 1 g wet diaper = \_\_ mL (subtract weight of diaper) - weigh all diapers, even with \_\_\_\_ Daily \_\_\_\_, \_\_\_ signs Lab Values = \_\_\_\_ bicarb, \_\_\_ h/h ->
- 1 ml
- stool
- weights, VS
- low bicarb, high H/H -> makes blood thick (hypercoaguable)
