What are the different types of hearing loss a preschooler may experience?
- Conductive hearing loss (such as from OME)
- Sensorineural due to damage to the cochlea and inner ear (cochlear implant for treatment)
- Central (problem with sound interpretation in the brain)
How is hearing loss evaluated in the preschooler?
- Audiologic assessment can be done in children as young as 3 years
- Infants tested differently at birth for referral
- Treatment and education are key
- conductive loss: hearing aids 2-2.5 yrs
- Conchlear Implant: sensorineural 8-12mo
- Vision also needs to be assessed as they will be relying more heavily on other senses (deficits will need to be corrected)
What nursing care can be done for the preschooler with hearing loss?
- Rooming in with the primary care giver
- Let the client see you before you touch them
- Use adequate lighting
- Promote other methods of communication, such as signing, lip reading, picture boards
- Teach care of hearing aids
What are some common vision impairments experienced by the preschooler?
- Refraction: light does not bend properly in eye and does not focus on the retina
- Myopia: near sightedness
- Hyperopia: far sightedness
- Astigmatism: Uneven corneas
- * A child's vision is essential in the their learning development, social development, coordination and safety
How is vision assessed? What is considered blindness?
- Can be assessed by a snellen chart, e-chart, or picture chart
- Ishihara test for color blindness
- Blindness can be caused by maternal infection during pregnancy or delivery
- Blindness is legally defines as 20/300 or less or peripheral vision less than 20 degrees
How is a vision impairment treated and what teaching can be done?
- The earlier vision impairment is treated, the better the outcome
- Corrective lenses may be used
- Large print, tapes, magnifying glasses, typewriters or computers, talking books and braille
- Identity self when coming into the room and before touch
- Other senses are heightened due to impairment
- Encourage independence

What interventions and teaching can be done for tonsillitis?
- Prevent aspiration
- Monitor for hemorrhage (persistent swallowing)- do not feed red colored food as it can mask blood
- 5-10 days post op is highest risk for hemorrhage
- Monitor VS, fluid intake, soft foods only
- Provide comfort measures

What is acute leukemia? What is the most common kind in childhood?
- Acute Lymphatic Leukemia accounts for 85% of childhood leukemias and is considered the most curable
- Peak onset between 3-5 yrs old
- Uncontrolled reproduction of immature white blood cells (lymphoblast)
- Rapid increase in lymphoblasts leads to a decrease in RBCs and platelets
What are the clinical manifestations of acute leukemia?

What is the prognosis for a child with acute leukemia and what factors influence the prognosis?
- If there is a relapse after HSCT, the prognosis is dismal
- Prognosis is determined by:
- Initial WBC count
- Age at time of diagnosis
- Type of cell involvement
- Gender (boys have a higher mortality rate)
- Karyotype analysis
What infection control precautions should be taken for a child on chemotherapy?
- Neutropenic precautions

- ITP may become chronic, rule out all other diseases
What us the treatment and nursing care for ITP?
- Corticosteroids (must rule out leukemia via bone marrow aspiration)
- IV immune globulin (IVIG) increases the production of platelets

- Massive urinary protein loss
- *often occurs in conjunction with a bacterial or viral infection
What changes occur in nephrotic syndrome?
- Glomerular membrane become permeable to proteins, esp albumin, which is then lost in the urine (hyperalbuminemia)
- Serum albumin is then decreased (hypoalbuminemia)
- Fluid shifts from plasma into the interstitial spaces leading to hypovolemia, ascites, and edema
How is nephrotic syndrome managed?

- Thorough perineal are
- Avoid incontinent episodes by answering call light and offering bed pan at frequent intervals
- Insure adequate fluid intake to dilute urine and flush bacteria
- Avoid bladder irritants such as caffeine alcohol, citrus juices, chocolate, and highly spiced foods
What discharge to home instructions should be given for Nephrotic syndrome?
- Follow up urine cultures will need to be done
- Recurrent symptoms may appear 1-2 weeks after therapy
- Encourage adequate fluids even after infection

- Always explain rationales to increase compliance
What is glomerulonephritis and what may it be related to?
- Usually appears 1-3 weeks after pneumococcal, streptococcal, or viral infections
- Can be a distinct entity
- May point to another disease such as systemic lupus erythematosus (SLE), sickle cell disease, or others
What are the symptoms of glomerulonephritis?
- Due to decreased glomerular filtration
- Begins with periorbital edema then progresses to the lower extremities and ascities
