Difficulty: MediumPreventive Care and Immunizations

Match each high-risk pediatric patient presentation with the most appropriate specific preventive care or immunization intervention.

  • A 2-year-old child with sickle cell anemia presenting for a well-child visitAdministration of the 23-valent pneumococcal polysaccharide vaccine (PPSV23)
  • A 4-month-old infant born at 28 weeks gestation presenting at the onset of the winter seasonAdministration of respiratory syncytial virus (RSV) monoclonal antibody prophylaxis
  • A 12-month-old child with severe combined immunodeficiency (SCID) presenting for routine immunizationsAbsolute contraindication to all live-attenuated viral and bacterial vaccines
  • A 6-year-old child with severe persistent asthma and a recent history of wheezingAdministration of the inactivated influenza vaccine, avoiding the live-attenuated intranasal formulation

Answer

The correct matches align each specific high-risk pediatric condition with its indicated modification to the standard immunization and preventive care schedule.
Each pairing correctly identifies the specific preventive care modification required for the patient's underlying condition: PPSV23 for functional asplenia at age 2, RSV prophylaxis for extreme prematurity, avoidance of live vaccines for severe cellular immunodeficiencies, and mandatory selection of inactivated (rather than live-attenuated) influenza vaccine for patients with severe asthma or recent wheezing.

Step-by-Step Solution

1
Evaluate the 2-year-old with sickle cell anemia.
Matches with administration of PPSV23.
Functional asplenia increases the risk of invasive pneumococcal disease, necessitating PPSV23 at age 2.
2
Evaluate the 4-month-old premature infant.
Matches with RSV prophylaxis.
Prematurity increases vulnerability to severe RSV disease during the winter season.
3
Evaluate the 12-month-old with SCID.
Matches with absolute contraindication to live vaccines.
Profound T-cell defects allow live vaccine strains (like MMR/Varicella due at 12 months) to cause uncontrolled, fatal infections.
4
Evaluate the 6-year-old with severe asthma.
Matches with inactivated influenza vaccine administration.
Live-attenuated influenza vaccine can trigger exacerbations in children with severe asthma or recent wheezing, requiring the inactivated form.

Key Concept

Immunization and preventive care modifications in high-risk pediatric populations (asplenia, prematurity, immunodeficiency, chronic pulmonary disease).
