Exam 1: Conditions That Produce F&E Imbalances Flashcards
(35 cards)
Diarrhea
Increase in frequency, fluidity and volume of stools
Types of Diarrhea
-Acute and chronic
Acute Diarrhea
- Self limiting
- subsides without specific treatment
Chronic Diarrhea
- > 14 days
- Often caused by chronic conditions (i.e malabsorption syndrome, IBD, immunodeficiency, food allergy and lactose intolerance)
Diarrhea: Evaluation
- Careful history such as living conditions, travel, exposure to untreated drinking/washing water, contact with animals, ABT and recent diet.
- Stool studies if indicated.
Nursing Management of Diarrhea: Assessment
Fluid and electrolyte imbalances
Nursing Interventions for Diarrhea
- Rehydration: continue to feed infants breast milk or formula
- Maintenance fluid therapy
- Reintroduction of adequate diet as soon as tolerated: bland but nutritional food (i.e crackers, flour tortillas); once they can tolerate bland can progress to normal diet.
- Protect the skin
What should you avoid giving patients with diarrhea?
- Sugary drinks
- No BRAT diet: bananas, white rice, apple sauce and white toast (will increase K+)
- ABT (alters normal intestinal flora)
- Anti-diarrhea medication is contraindicated
Diarrhea Transmission
Fecal-oral route
Rotavirus
- Cause 70-80% of infectious diarrhea
- Most severe in 3-24 months (<3 months have some protection from maternally acquired antibodies)
- Vaccine now available.
Rotavirus Vaccine
- Given at 2 & 4 months OR 2,4,6 months
- PO Vaccine (makes parents more willing to give to children)
Shock
- AKA circulatory failure
- An acute, unstable physiologic state of inadequate oxygen delivery to the tissues.
Shock can result in
- Cellular dysfunction
- Eventual organ damage/failure
What are the types of shocks?
- Hypovolemic Shock
- Cardiogenic Shock
- Distributive Shock
- Obstructive Shock
- Septic Shock
Hypovolemic Shock
- Most common in children
- Overall decrease in circulating blood or volume.
What can cause hypovolemic shock?
- Trauma
- Bleeding
- Burns
- Diarrhea
- Dehydration
- Surgery
Cardiogenic Shock
- Usually general in heart disease (PICU)
- Due to impaired cardiac muscle function.
- Cardiac output is not sufficient to meet the body’s metabolic demands.
What can cause cardiogenic shock?
- Congenital heart disease
- May be seen after cardiac surgery
Distributive Shock
-Due to vascular abnormality that produces maldistribution of blood supply throughout the body.
Distributive Shock includes???
- Neurogenic Shock
- Anaphylactic Shock
- Septic Shock (most common if child has fever always work up for septic shock)
Obstructive Shock
- Not common in children
- Venous congestion with poor perfusion.
What can cause obstructive shock?
- Cardiac tamponade
- Tension pneumothorax
- Pulmonary embolism
Septic Shock
-Caused by infection
Presentation of Septic Shock
- Diffuse vasodilation
- Increased capillary permeability
- Maldistribution of blood flow
