NU 605 exam 3 study guide questions
|| || || || || || ||
with precise detailed solutions || ||
1. Rocky Mountain Spotted Fever: Rickettsia rickettsii caused by a tick
|| || || | || || || || || ||
bit most common in the spring and summer months
|| || || || || || || ||
incubation 2-14 days || ||
2. Symptoms Rocky Mountain Spotted Fever: Fever 104 in 98% of children
|| || || || || || || || || || ||
Chills, myalgias, severe headache, malaise, GI upset/tenderness, diarrhea,
|| || || || || || || ||
cough, conjunctival injection, photophobia, altered mental status
|| || || || || ||
Focal neurological deficits - paralysis, transient deafness with progression
|| || || || || || || ||
3. Rash in Rocky Mountain Spotted Fever: Maculopapular
|| || || || || | ||
rash Typically 2-5 days after fever onset
|| || || || || ||
Rash begins as a small, flat nonpruritic faintly pink spots on the wrists, forearms,
| | | || || || | | | | | | | |
| ||
,and ankles, then spread to trunk, sometimes to sole and arms
|| || || || || || || || || ||
Petechial rash on day 6 sign of disease progression.
|| || || || || || || ||
4. Diagnosis for Rocky Mountain Spotted Fever: Gold standard is IFA on
|| || || || || | || || || ||
paired serologic samples taken in the first week and 2 to 4 weeks later.
|| || || || || || || || || || || || ||
Antibody titer may be absent in the first 7 to 10 days
|| || || || || || || || || || ||
The fastest available test is PCR or immunohistochemical staining
|| || || || || || || ||
5. Treatment for Rocky Mountain Spotted Fever: Start within 5 days of
| || || | | | | | | |
symptoms due to possible false negative to prevent death
|| || || || || || || ||
Doxycycline all ages 7 to 10 days || || || || || ||
children less than 100lbs 2.2mg/kg per dose twice
|| || || || || || || ||
daily children greater than 100lbs 100mgs twice daily
|| || || || || || ||
6. Anisocoria: unequal pupil size | || ||
7. myopia: nearsightedness - can see near objects but not far objects
| || || || || || || || || ||
| ||
,8. strabismus: defect in ocular alignment or the position of the eyes in | || || || || || || || || || || ||
relation to each other (commonly called lazy eye)
|| || || || || || ||
one or both eyes can be appeared cross
|| || || || || || ||
9. Clinical findings strabismus: ´Intermittent exotropia (eye turned
|| || || || || || ||
outward) in normal children 6 months to 4 years, when tired, ill,
|| || || || || || || || || || ||
´Child fixates with unaffected eye
|| || || ||
´Angle of deviation may change in different fields of gaze
|| || || || || || || || ||
´Persistent squinting, head tilting, face turning, nystagmus, overpointing,
|| || || || || || || ||
awkward- ness, marked decrease in acuity in one eye
|| || || || || || || ||
´Cataracts, Retinoblastoma, anisometropia, severe refractive errors infrequent
|| || || || || ||
10.Diagnostic techniques for strabismus: ´Diagnostic techniques-photo | || || | | |
screen- er can be used
|| || || ||
´Corneal light reflection || ||
| ||
, ´Cover-uncover test and alternating cover test
|| || || || ||
11.Management for strabismus: ´Refer to ophthalmologist if >4 months and
|| || || || || || || || || ||
mis- alignment
