Final answer:
The term 'CD' related to pregnancy is not clearly defined, making it challenging to provide a specific reason for administering digitalis. Typically, digitalis is used for heart conditions and must be prescribed cautiously during pregnancy due to potential risks to the fetus.
Step-by-step explanation:
The question appears to involve the use of digitalis in the context of complications during pregnancy. However, the common indication for digitalis, specifically the drug Digoxin, is in managing certain heart conditions such as atrial fibrillation or heart failure, not pregnancy-related conditions directly. Given that the abbreviation 'CD' is not clearly defined in the context of pregnancy, it's difficult to provide a precise answer. It is critically important to avoid any fetotoxic substances during pregnancy due to the risk they pose to the developing fetus. Furthermore, hormonal changes in pregnancy can lead to a shift in the microbiota composition, resulting in a higher incidence of infections for which appropriate treatment is essential. If digitalis is to be prescribed during pregnancy, it would be under careful consideration of potential benefits and risks and usually for the mother's cardiac-related conditions rather than pregnancy complications.
