A nurse in a provider's office is caring for a group of clients who have communicable diseases. Which of the following infections should the nurse report to the state health department?

A) Rolls from back to abdomen: Rolling from back to abdomen is a typical developmental milestone for a 4-month-old infant. By this age, infants usually have increased muscle strength and coordination, allowing them to start rolling over. This movement helps build their core strength, which is important for later developmental milestones like sitting up and crawling.

B) Moves objects to mouth: It is common for a 4-month-old to move objects to their mouth as they begin exploring the world around them. This action is a key part of sensory development and helps infants develop their hand-to-mouth coordination. Additionally, this behavior assists in teething and the development of oral motor skills.

C) Anterior fontanel closed: The anterior fontanel normally closes between 12 to 18 months of age. If it is closed at 4 months, it may suggest abnormal cranial growth, such as craniosynostosis, where the sutures of the skull close too early. This could lead to increased pressure on the brain, which can cause developmental delays or other complications, so the provider should be notified for further assessment.

D) Posterior fontanel closed: The posterior fontanel typically closes by 2 to 3 months of age. If it is closed by 4 months, it is completely normal and indicates proper cranial development. The closing of the posterior fontanel helps ensure the skull's bones are fusing together as expected, and it does not raise any concerns at this stage.

A) Rubella titer nonimmune: A nonimmune rubella titer indicates that the client is not immune to rubella, which is a common finding in many pregnant women. However, rubella vaccination is not given during pregnancy because the vaccine is a live virus. The client will typically be vaccinated postpartum. Follow-up would be required, but it is not an urgent concern during the pregnancy itself.

B) Negative varicella titer: A negative varicella titer means the client is not immune to chickenpox, which is a concern because varicella can cause serious complications during pregnancy. However, similar to rubella, the varicella vaccine is contraindicated during pregnancy, and vaccination would be given postpartum. This requires follow-up after delivery but does not require urgent intervention during the pregnancy.

C) Positive Rh factor: The Rh factor is a blood type characteristic, but what is typically more concerning is the Rh incompatibility, which occurs when a Rh-negative mother carries a Rh-positive baby. A positive Rh factor is not a problem for the client themselves but could be important if the father is Rh-positive. If there is concern for Rh incompatibility, the nurse would monitor for the development of Rh sensitization and administer Rh immunoglobulin (RhoGAM) if needed. This does not require urgent intervention unless Rh incompatibility is confirmed.

D) Positive serologic test for syphilis: A positive test for syphilis requires immediate follow-up intervention. Syphilis is a sexually transmitted infection that can cause serious complications during pregnancy, including miscarriage, stillbirth, preterm birth, and congenital syphilis. Treatment with penicillin is recommended to prevent transmission to the baby and to treat the infection in the mother. A positive serologic test for syphilis warrants prompt intervention.
