A young adult arrives at an outpatient clinic for a routine wellness check and is scheduled to receive the measles, mumps, and rubella (MMR) immunization. While filling out the pre-assessment questionnaire, the client mentions missing her last menstrual cycle and having a positive home pregnancy test three days ago. Based on these findings, which action should the practical nurse implement?
- Explain that this specific vaccine formulation is unsafe during pregnancy and report the information to the attending provider.Answer
- BReassure the individual that the injection provides critical fetal protection against viral complications and complete the administration.
- CDetail the potential teratogenic risks, secure a signature on an advanced liability waiver, and provide the dose.
- DDelegate the responsibility of educating the client regarding post-vaccination pregnancy precautions to the medical assistant.
Answer
Explain that this specific vaccine formulation is unsafe during pregnancy and report the information to the attending provider.
The MMR vaccine is a live-attenuated virus. Administering it during pregnancy can lead to congenital rubella syndrome and other severe teratogenic effects. The practical nurse acts safely and within scope by identifying this absolute contraindication from the pre-assessment data, withholding the injection, and promptly reporting the client's potential pregnancy status to the healthcare provider.
Step-by-Step Solution
Key Concept
Live-attenuated vaccines (such as MMR and varicella) are strictly contraindicated during pregnancy due to the risk of severe congenital abnormalities. The practical nurse must routinely screen for pregnancy before administration, withhold the vaccine if pregnancy is suspected, and notify the healthcare provider.
