Which observation by the nurse indicates a need for further teaching in a client beginning week 30 of gestation?

Wearing knee-high hose during pregnancy can be a strategy for managing or preventing swelling and varicose veins, which are common concerns as the pregnancy progresses. However, the appropriateness of this choice can depend on the specific circumstances and the guidance provided by the healthcare provider. The need for further teaching may be indicated if the use of knee-high hose is not recommended for this particular patient based on her health status or if there are concerns about circulation that could be exacerbated by them.

In contrast, the other observations reflect positive aspects of the client's pregnancy. Regular fetal movements are an indication of fetal well-being, an appropriate amount of weight gain suggests that the pregnancy is progressing healthily, and having no concerns can indicate that the client feels confident and well-prepared for the remainder of her pregnancy. Each of these points underscores the importance of monitoring both maternal and fetal health during this stage of gestation.
