Which of the following should be included in the plan of care for preterm infants?
use of a car seat without a shield harness
supplemental vitamin D at 4 months for breast fed infants
immunizations beginning at 2 months corrected age
evaluation of vision at 3 months - CORRECT ANSWER-use of a car seat without
a shield harness
Preterm infants eligible to ride in car safety seats should not use the shield
harness because it may be too large for a smaller infant. Breastfed infants should
be supplemented with vitamin D until they are taking at least 1 liter per day of
vitamin D fortified formula or whole milk. Immunizations are administered at the
,appropriate scheduled times, on the same schedule as full term infant
counterparts. Vaccinations with DTaP, IPV, Hib and Rotavirus should occur at two
months chronological, not corrected, age. Preterm infants should have vision
tested annually beginning at six months.
The late preterm infant has which of the following risks?
excessive wakefulness
poor sucking strength
tachycardia
colic - CORRECT ANSWER-- poor sucking strength
The term "late preterm birth" or "late preterm infant" includes infants born
between 34 weeks and 36 6/7 weeks. This late preterm infant has few wakeful
periods so time awake should be used for feeding. These infants can also have
significant difficulty in developing a coordinated suck, swallow and breathing
,pattern. At birth, the late preterm infant has an increased potential to develop
apnea, bradycardia, hypoglycemia, and sepsis. Infants in this gestational age
group are not more likely to develop colic or have tachycardia.
A 4 month old with congenital nasolacrimal duct obstruction had several episodes
of dacryocystitis and is currently hospitalized for cellulitis. Which is the
appropriate follow up?
continued frequent massage over the lacrimal duct
daily use of an ophthalmic antibiotic ointment
surgical referral for potential tear duct probing
oral antibiotic prophylaxis - CORRECT ANSWER-surgical referral for potential
tear duct probing
The child at highest risk for having an elevated blood lead level is a:
3 month old exclusively breastfed infant
, 6 month old who lives in a home built after 1970
2 year old with iron deficiency anemia
2 year old who is a picky eater
D. - CORRECT ANSWER-2 year old with iron deficiency anemia
The amount of lead absorbed from the gut is increased in children with nutritional
deficiencies such as iron deficiency anemia (IDA). Iron deficiency anemia is often a
comorbidity of lead poisoning. The hand-to-mouth behavior of infants and young
children increases their lead exposure. However, living in a home built after 1970
reduces the risk since residential paint used in that era should not have been lead
based. Infants more than 4 months of age exclusively breast fed without
supplemental iron are at increased risk of IDA. A child who is a picky eater may or
may not be at high risk for IDA, depending on foods actually eaten.Which
laboratory assessment is the BEST indicator of vitamin D deficiency?
