Answer:
When a mother transmits syphilis to her baby during birth, the child can experience various impairments and health issues. One of the most common issues is poor feeding and vomiting. This is because syphilis can affect the baby's liver, leading to liver dysfunction and associated symptoms like poor feeding and vomiting.
So, the correct answer is:
D. Poor feeding and vomiting.
However, it's important to note that syphilis can have a range of effects on an infant's health, and the specific impairments can vary depending on the severity of the infection and how early it is treated. Close medical monitoring and treatment are essential in cases of congenital syphilis to address any potential health problems and support the child's development.
