Which action is performed if there are signs of poor cardiac output during a C assessment?

When poor cardiac output is detected during a clinical assessment, administering intravenous fluids is a crucial step in managing the situation. This action is aimed at improving the patient's circulatory status by enhancing blood volume, which can help support the heart's ability to pump effectively.

Poor cardiac output can lead to inadequate tissue perfusion and organ dysfunction, making it essential to take steps that can quickly restore hemodynamic stability. Intravenous fluids, particularly crystalloids, can provide the necessary volume to potentially reverse signs of shock and improve the delivery of oxygen and nutrients to tissues.

While the other responses may be relevant in a broader context of emergency care, administering intravenous fluids directly addresses the potential underlying issue of hypovolemia or poor blood flow, which is critical in situations of compromised cardiac output. Starting immediate CPR is appropriate for unresponsive patients without a pulse, while conducting a physical exam and checking for a pulse are parts of a more comprehensive assessment but do not actively address the immediate concern of inadequate cardiac output.
