1
Q
Accurate temperature measurement in children
A
Rectal thermometer in children < 3 y.o.
Oral thermometer in children > 5 y.o.

(36. 6-37.9C)
3
Q
T/F Degree of fever correlates with severity of illness

* entecavir or tenofovir safe and effective x 12 months after HBsAg is - and HBV DNA is undetectable
168
if mother has chronic hepatitis B (hep B surface antigen +) after an infant is born…
infant should get hep B vaccine and immunoglobulin within 12 hours of birth
if not, 90% of infants will get chronic hep B
test infant in 6-9 months for antigen and antibody
169

182
HIV + mom concerned about unborn child. with effective therapy, risk of transmission
lowered to \< 2 %
after delivered, baby started on AZT for 4-6 wks to prevent HIV infxn
183
steps to prevent HIV transmission from mom to baby
* mom with HIV take HIV meds during pregnancy and childbirth.
* bb takes AZT (zidovudine) for 4-6 weeks after birth.
* Goal: lower viral load \< 1000 in mom = dec transmission to baby
* mom \> 1000 viral load → C-section
* if \< 1000 viral load → vag delivery
* No breastfeeding
* NB need RNA/DNA check at 2 wks, repeat 1-2 months, then 4-6 months, then 12-18 months.
* Negative HIV antibody confirms bb not infected
184
is infant's blood is taken day 1 and at 2 week mark and is + for HIV, this means
we don't know!
we expect to see antibodies up to 6 months bc it crosses the placenta so we have to test for HIV antibodies up to 6 months.
test viral load at birth, at 1-2 weeks, then 1-2 months, then 6 months
if 2 RNA are + = confirms dx
185
How should the HIV status of the infant be determined?
Viral load by PCR at 2-3 weeks, 1 to 2 months, and 4 to 6 months
186
HIV and pneumococcal vaccine?
