(54 cards)
Variations in Anatomy - Eyes: When is iris color determined?
By 6-12 months of age. They are born with blue eyes.
Variations in Anatomy- Eyes: Infant sees best at what distance?
8-10 inches
Variations in Anatomy- Eyes: When is 20/20 vision obtained?
By 6-7 years
Variations in Anatomy - eyes: When does binocular vision develop?
By 4 months of age
Variations in Anatomy -Ears: Main difference here between adult and child?
Eustachian tube is straight in a child, but slants as they grow older.
Common Medical Tx, Health Hx: Past medical history may be significant for what?
Prematurity, genetic defect, eye or ear deformity or deafness.
Common Medical Tx, Health Hx: When asking parents about history, ask then about onset and progression and presence of what?
Fever, nasal congestion, eye/ear pain, eye rubbing, ear pulling and headache.
Common Medical Tx, Health Hx, Inspection: Note what about the eyes?
Whether child uses eyeglasses, corrective lenses, or hearing aid. Observe eyes for positioning and variations in eyelids.
Common Medical Tx, Health Hx, Inspection: What to know about sclera in newborns?
They will appear bluish in newborns, but become white within the first few weeks of life.
Common Medical Tx, Health Hx, Inspection: Ears will be checked for what?
Size/Shape, Position, and Presence of skin tags, dimples.
Common Medical Tx, Health Hx, Palpation: Ears should be palpated for what?
Tenderness over tragus or pinna.
Common Medical Tx, Health Hx, Palpation: What does Typanometry do?
Probe in ear canal measures movement of eardrum
Acute Otitis Media (AOM): What is this?
Common illness in children, resulting from infection (bacterial or viral) of fluid in the middle ear.
Acute Otitis Media (AOM): Why are children more prone to get this?
Due to short length and horizontal positioning of the Eustachian tube, and limited respones to antigens
Acute Otitis Media (AOM): Biggest risk factors for this?
Eustachian tube dysfunction and susceptibility to recurrent upper respiratory infections
Acute Otitis Media (AOM) - Patho: What frequently precedes this?
Upper respiratory infection. They travel upward invading the middle ear space.
Acute Otitis Media (AOM) - Patho: What occurs acutely once invasion begins?
Fever and pain. Increased pressure behind membrane may cause proliferation resulting in decreased pain and yield drainage.
Acute Otitis Media (AOM) - Patho: What happens once infection clears?
Fluid remains in the middle ear space behind the tympanic membrane after several months.
Acute Otitis Media (AOM) - Patho: Most common complications from this?
Hearing loss, expressive speech delay, typanosclerosis, tympanic membrane perforation, and chronic suppurative otitis media.
Acute Otitis Media (AOM) - therapeutic mx: Viral treatment?
They usually resolve spontaneously
Acute Otitis Media (AOM) - therapeutic mx: Bacterial treatment?
Require treatment with an antibiotic.
Acute Otitis Media (AOM) - therapeutic mx: How can this be determined?
Culture of middle ear. Also can check fluid obtained via tympanostomy in children with AOM.
Acute Otitis Media (AOM) - therapeutic mx: Why does antibiotic resistance develop?
Due to overuse of antibiotics.
Acute Otitis Media (AOM) - therapeutic mx: Certain diagnosis of this is based on what?
Signs of fluid in middle ear, with moderate to severe bulging of tympanic membrane with complaint of ear pain.
Along with sign and symptoms of inflammation in middle ear.
