Zorluk: OrtaPreventive Care and Immunizations

A pediatric clinic is reviewing the immunization records of several patients with specific underlying conditions or clinical circumstances. Match each pediatric patient with the specific vaccine or immunoprophylaxis that is most appropriately indicated for their ongoing care.

  • A 16-year-old adolescent boy with a newly diagnosed terminal complement pathway deficiencyMeningococcal B (MenB) vaccine series
  • A 15-year-old adolescent girl who is currently at 28 weeks of gestationTetanus, diphtheria, and acellular pertussis (Tdap) vaccine
  • A 3-year-old boy scheduled to undergo cochlear implant surgery next month23-valent pneumococcal polysaccharide vaccine (PPSV23)
  • A 6-month-old infant boy born at 26 weeks gestation with bronchopulmonary dysplasia, presenting for a visit in late OctoberRespiratory syncytial virus (RSV) immunoprophylaxis

Cevap

The correct matches align specific high-risk pediatric conditions with their targeted immunizations: complement deficiency pairs with MenB, pregnancy pairs with Tdap, cochlear implants pair with PPSV23, and premature infants with lung disease pair with RSV immunoprophylaxis.
Each patient in the stem presents with a specific risk factor that directly alters their routine immunization requirements. Terminal complement deficiency requires MenB to prevent lethal meningococcal disease. Pregnancy necessitates Tdap in the third trimester for neonatal pertussis protection. Cochlear implants place children at high risk for pneumococcal meningitis, requiring PPSV23 in addition to standard conjugate vaccines. Premature infants with chronic lung disease require RSV immunoprophylaxis entering their first RSV season.

Adım Adım Çözüm

1
Evaluate the immunization needs of the 16-year-old with terminal complement deficiency.
Matches with Meningococcal B (MenB) vaccine.
Terminal complement deficiency impairs the body's ability to lyse encapsulated bacteria, specifically creating a severe vulnerability to Neisseria meningitidis, necessitating complete meningococcal vaccination (MenACWY and MenB).
2
Evaluate the immunization needs of the pregnant 15-year-old at 28 weeks gestation.
Matches with Tdap vaccine.
Standard prenatal care guidelines require Tdap administration between 27-36 weeks in every pregnancy to ensure protective maternal antibodies are transferred to the infant against pertussis.
3
Evaluate the immunization needs of the 3-year-old needing a cochlear implant.
Matches with 23-valent pneumococcal polysaccharide vaccine (PPSV23).
Cochlear implants provide a potential anatomical pathway for bacteria to enter the central nervous system, heightening the risk for pneumococcal meningitis. PPSV23 expands serotype coverage for high-risk children over age 2.
4
Evaluate the immunization needs of the premature 6-month-old with bronchopulmonary dysplasia entering autumn.
Matches with RSV immunoprophylaxis.
Premature infants with chronic lung disease lack adequate airway reserves and maternal antibody transfer, requiring passive immunization against RSV during the peak transmission season.
