Which sign indicates that a pregnant client may need immediate medical attention?

Visual disturbances during pregnancy can be a significant indicator of potential complications, such as preeclampsia or gestational hypertension. These conditions can endanger both the mother and the fetus if not addressed promptly. Visual disturbances may include blurred vision, seeing spots, or sudden loss of vision, which can suggest increased blood pressure and other serious health issues.

Persistent headaches can sometimes occur in pregnancy due to hormonal changes or other non-serious factors, but they are not necessarily indicative of an immediate threat. Similarly, swelling in the lower legs is common in pregnancy and may not require urgent intervention unless accompanied by other concerning symptoms. Infrequent urination can also occur for various benign reasons, such as dehydration or simply due to the baby’s position, and does not typically signal a need for immediate medical care. Therefore, visual disturbances stand out as a crucial warning sign that prompts urgent evaluation and intervention.
