A 2-month-old child you have followed since birth arrives for his rou-tine “baby shots.” His mother’s pregnancy was uncomplicated, and he has been healthy without significant problems.
What is the next step in the care of this patient?
Routine Well-Child Care
Summary: A healthy 2-month-old infant due for a routine well-child visit.
Next step: Gather interval history (feeding, sleep), obtain appropriate meas-urements (length, weight, and head circumference), review sensory and devel-opmental or behavioral screenings (ensure that he can see and hear, and that he is developing normally), perform a physical examination, perform general and specialized procedures (ensure that his neonatal state screen is normal and provide immunizations), and offer anticipatory guidance.
ANALYSIS
Objectives
1. Become familiar with the goals of the routine well-child (or health super-vision) session.
2. Become familiar with the American Academy of Pediatrics (AAP) Recommended Childhood and Adolescent Immunization Schedule.
3. Learn the side effects and contraindications of common childhood immu-nizations.
Considerations
Well-child care for this healthy infant is uncomplicated. For children with special needs, such as Down syndrome or sickle cell disease, guidelines outline their specific considerations. For children with multiple handicaps, such as those resulting from extreme prematurity, no specific guidelines exist; the providers adapt national “well-child care” guidelines as appropriate.
APPROACH TO
Childhood Well-Child Care
CLINICAL APPROACH
Goals of a health supervision visit include evaluating a child’s physical, devel-opmental, psychosocial, and educational status to identify problems early; prompt intervention then can be instituted. Anticipatory guidance aims to fos-ter good health habits, prevent illness, and assist in family communication.
Most pediatric providers follow commonly available preventive health-care guidelines. The AAP periodically updates its Recommendations for Preventive Pediatric Health Care, which outlines questions, medical procedures, and coun-seling areas for children’s birth through 21 years. Other sources include guide-lines from the Agency for Healthcare Research and Quality and “Bright Futures” (National Center for Education in Maternal and Child Healthcare). Regardless of the source, guidelines are modified to fit local practice and to best serve the patients’ needs.
IMMUNIZATIONS
Immunizations are part of the well-child visit. They are cost-effective and effi-cacious in improving children’s general health and well-being. Vaccination pro-grams have eliminated smallpox and reduced the incidence of other diseases (Haemophilus influenzae type b [Hib], polio, measles, tetanus, rubella, and diph-theria) such that medical students and residents are unlikely to see a single case. The Recommended Childhood and Adolescent Immunization Schedule (Figure 9–1), updated annually and available on the Internet, is supported by a variety of organizations, including the AAP, the American Academy of Family Practice, and the Centers for Disease Control and Prevention.
Pediatric immunizations are extraordinarily safe. The side effects risk is extremely low, especially when compared to the benefit of preventing mor-bidity and mortality from communicable diseases. However, vaccine safety sometimes is scrutinized by the news media and by parents. The health-care provider must have access to scientifically sound and updated side effect data to allay these fears (Table 9–1).
Many American children are incompletely immunized because of a lack of access to immunizations, poor family understanding of the need for immu-nizations, cost, or fear of side effects. True contraindications to giving immu-nizations are rare. Mild upper respiratory infections, gastroenteritis, and low-grade fever are not contraindications.
True contraindications to a particular vaccine include immediate hyper-sensitivity reactions to the given vaccine, the vaccine component, or the pre-servative in the agent. True egg hypersensitivity is a contraindication to influenza and yellow fever vaccination (both grown in chick embryo tissue cultures) but not for measles-mumps-rubella (MMR) vaccination (contains only minute amounts of egg products). Patients having encephalopathy or encephalitis after receiving the diphtheria, tetanus, and pertussis vaccine do not receive subsequent doses. In general, live virus vaccines are not given to preg-nant and severely immunocompromised patients, but they are given to a child living in the home with a pregnant woman. Giving MMR or varicella to an asymptomatic patient with human immunodeficiency virus (HIV) is permitted. Expert consultation in some cases is warranted.

(hypotonic-hyporesponsive episode) within 48 h of receiving a prior dose of
DTP/DTaP. • Seizures within 3 d of receiving a
prior dose of DTP/DTaP (acetaminophen given prior to administering DTaP or
DTP and every 4 h thereafter for 24 h should be considered for children with
a personal or family history of convulsions in siblings or parents). • Persistent, inconsolable crying
lasting >3 h within 48 h of receiving a prior dose of DTP/DTaP. • Guillain-Barré syndrome within 6 wk

within 1 mo of immuni-zation, a mild maculopapular or varicelliform rash
(median of about 2-5 lesions) at the injection site or elsewhere, develops in
about 7% of children and about 8% of susceptible adolescents/adults. Pain,
redness, and/or swelling at
the injection site in 20% of children and 25%-35% of adolescents. Transmission
of the vaccine virus
from healthy vaccines to other persons is rare (<1%) and appears to occur
only if vaccine develops rash. Transmission of this vaccine virus appears to
cause mild or no disease. Zoster-like

Comprehension
Questions
9.1 A healthy, well-developed 6-year-old child
arrives as a new patient to your clinic. His immunization card reveals that he
received an immu-nization at birth and some when he was 2 months old, but none
since. Which of the following statements about him is correct?
A. He should receive the live oral
poliovirus vaccine rather than the inactivated (injectable) poliovirus vaccine
(IPV).
B. The pertussis vaccine is contraindicated
at his age and is replaced with the tetanus-diphtheria vaccine.
C. He is too old to receive the H influenzae
type b vaccine.
D. His vaccinations at birth and 2 months are
repeated because too much time has elapsed for them to be effective.
E. He is too young for the varicella
vaccine.
9.2 Appropriate advice for a mother of a
2-week-old child here for a “well-child” visit includes which of the following?
A. By age 1 month the child should be
sleeping through the night.
B. Children should be able to roll over by
age 2 months and to sit by age 4 months.
C. Half-strength fruit juices can be
initiated at age 2 months.
D. Potty training should begin at age 1 year.
E. Sleep in the supine position is
recommended.
9.3 During a “well-child” visit, the parents of
a healthy 5-month-old offer a great amount of information. Which of the
following bits of infor-mation is of most concern?
A. A diet that includes baby cereal, five
different baby vegetables, and one baby fruit
B. Consuming 32 oz of infant formula per day
C. Intermittent tugging on the ears
D. Limited eye contact with parents
E. Rolling from front to back but not back
to front
9.4 Which of the following statements about
“routine” screening tests is accurate?
A. All children undergo tuberculosis skin
testing at age 12 months.
B. Lead testing is obtained on all 12- and
14-month-old infants.
C. Pelvic examinations are part of the
examination of a sexually active adolescent.
D. Screening hematocrit levels are obtained
on all infants at age 2 months.
E. Universal cholesterol screening begins at
age 11 months.
ANSWERS
9.1 C. The Hib vaccine generally is not
recommended for children 5 years of age or older.
9.2 E. Juices (undiluted) are avoided until
approximately 6 months of age (in a cup and not in the bottle). At 1 month of
age an infant should be able to fix and follow, but not be expected to sleep
through the night by age 2 to 3 months. Realistic targets for development
include rolling over at 4 months and sitting by 6 months. Potty training starts
when the child shows interest, usually no earlier than age 2 years. Parents are
told to place healthy children on their backs (or side) for sleep to reduce the
incidence of sudden infant death syndrome.
9.3 D. Children fix and follow on the human
face from birth. A 5-month-old child who does not engage in eye contact is
abnormal.
9.4 C. Tuberculosis and lead testing are
performed on at-risk children. Pelvic examinations are performed when girls
become sexually active or by age 18 to 21 years. Screening hematocrits are done
at age 9 to 12 months, and cholesterol tests are done for children with
familial risk factors.
Clinical
Pearls
➤ True contraindications for vaccinations
are rare but include immediate hypersensitivity reactions to the vaccine, the
vaccine component, or the preservative in the agent.
➤ Conditions that are not contraindications
for vaccinations include mild upper respiratory infections, gastroenteritis,
and low-grade fever.
➤ In general, pregnant and severely
immunocompromised patients should not receive live virus vaccinations, but the
vaccines are given to children liv-ing in the home with a pregnant woman.
Measles-mumps-rubella (MMR) and varicella vaccinations can be given to
asymptomatic patients with HIV.
