What should a nurse tell a client with a rubella titer of less than 1.8?

When a client has a rubella titer of less than 1.8, it indicates that the individual does not have adequate immunity to rubella. In this situation, it is essential for the nurse to inform the client that the test may need to be repeated during the pregnancy. This is crucial because if the client is not immune and is exposed to rubella during pregnancy, it can lead to serious complications for the developing fetus, including congenital rubella syndrome, which can result in severe birth defects.

Repeating the test allows healthcare providers to monitor the client’s immunity status throughout the pregnancy and take appropriate actions if needed. It is also important to educate the client about the significance of maintaining immunity before becoming pregnant and the potential risks associated with rubella exposure during pregnancy.

The other options do not accurately reflect the implications of a low rubella titer. A titer of less than 1.8 signifies a lack of immunity, not a normal result or a confirmed exposure to the virus. It also does not indicate that the client has developed immunity, which would not be the case with such a low titer.
