During a pediatric wellness visit, a practical nurse gathers intake data for an 8-week-old infant scheduled to receive routine immunizations, including the live-attenuated rotavirus vaccine. Which finding from the family's health history represents an absolute contraindication to administering this specific immunization?

  1. A
    The infant exhibited a localized red wheal and a temperature of 100.4°F (38.0°C) after receiving the birth dose of the hepatitis B vaccine.
  2. B
    The gestational parent adheres to a restrictive cultural diet and exclusively feeds the infant a specialized soy-based commercial formula.
  3. The gestational parent received continuous infusions of a biologic immunosuppressant medication throughout the third trimester of pregnancy.Cevap
  4. D
    The infant demonstrates a strong palmar grasp reflex but has not yet developed the ability to independently roll from the abdomen to the back.

Cevap

The finding that the gestational parent received continuous infusions of a biologic immunosuppressant medication throughout the third trimester of pregnancy represents an absolute contraindication.
Live-attenuated vaccines contain a weakened form of the virus that requires a competent immune system to process safely. Biologic immunosuppressant medications actively cross the placenta, especially during the third trimester. This maternal transfer results in systemic immunosuppression in the newborn that persists for up to six months. Because the infant cannot mount a safe immune response, administering a live vaccine like rotavirus is absolutely contraindicated due to the high risk of widespread, life-threatening viral infection.

Adım Adım Çözüm

1
Analyze the specific properties of the scheduled immunizations.
The rotavirus vaccine is identified as a live-attenuated viral vaccine.
Live vaccines carry an inherent risk of causing active, uninhibited infection in clients whose immune systems cannot mount a proper defensive response.
2
Evaluate the clinical significance of maternal third-trimester biologic therapy.
Biologic immunosuppressants (like TNF-alpha inhibitors) actively cross the placenta during late pregnancy.
This transplacental transfer effectively renders the newborn systematically immunocompromised for the first six months of life until the maternal antibodies clear from the infant's circulation.
3
Synthesize findings to determine safe nursing practice within the practical nurse scope.
The practical nurse must recognize the infant is functionally immunocompromised and withhold the live-attenuated rotavirus vaccine.
Administering a live virus to an immunocompromised infant poses a critical safety risk, requiring immediate escalation and consultation with the prescribing provider.
