Sleeping position

Answer 14

On back to prevent SIDS

Question 15

CDC vaccination schedule

Answer 15

See CDC

Question 16

By when should an infant double and triple its birthweight?

Answer 16

Double by 5 months

Triple by 12 months

Question 17

Red reflex

Answer 17

*Red/orange color reflected from the fundus through pupil when viewed through ophthalmoscope 10 inches from the patient
*Normal if symmetric coloration and no leukocoria
*Absence of a red reflex may indicate underlying abnormalities, including:
Cataracts
Glaucoma
Retinoblastoma
Chorioretinitis

Question 18

Acetaminophen and vaccines

Answer 18

May cause a lower antibody response, and should be administered only if absolutely necessary

Question 19

Anticipatory guidance

Answer 19

*Sleep: Place on back to prevent SIDS. Most babies sleep through night by age 4 to 6 months. Infants at 6 months of age usually sleep through the night and take two naps
during the day
*Car seat: Infants facing rear, in middle of back seat. The most effective car-seat restraint is a five-point harness. Children < 13 years should not sit in the front seat.
*Other: child care, tobacco exposure, childproof home, walkers not recommended

Question 20

Rectal exam in infant

Answer 20

Only when intra-abdominal, pelvic, or peri-rectal process suspected

Question 21

Neuroblastoma

Answer 21

• The most frequently diagnosed neoplasm in infants–more than half of patients present before age 2
• Presents as painless mass in the neck, chest, or abdomen
• Asymptomatic, or chronically ill with bone pain from bone marrow or skeleton mets. Fever, pallor, and weight loss are frequent presenting symptoms.
• Neuroblastoma is a likely diagnosis in an infant younger than a year of age who has an asymptomatic RUQ abdominal mass and pallor and no jaundice
• Normocytic anemia and small cell rosettes in the bone marrow
• Elevated urinary catecholamines
• Stage 4S disease carries a favorable outcome (infant <1yo)

Question 22

RUQ mass in a 9 month old

Answer 22

DDx:

• Neuroblastoma
• Wilms’ tumor (nephroblastoma)
• Teratoma
• Hepatic tumor
• Hydronephrosis

Question 23

By when should an infant double its birth length?

Answer 23

48 months (4yo)

Question 24

Developmental surveillance versus screening

Answer 24

*Surveillance: Comparing a child to expected behaviors by age. Not as sensitive or specific as screening
*Screening: Assessment using evidence-based tool to pick up developmental or behavioral abnormalities. PEDS (Parents’
Evaluation of Developmental Status) for birth to 8 years. May take place routinely during well-child visit or at any patient encounter
where there are concerns.

Question 25

Immunizations received by age 5

Answer 25
