Which of the following can be a sign of inadequate cardiac output?

• A. Poor peripheral circulation
• B. Increased energy levels
• C. Stable vital signs
• D. Regular heart rhythms

Answer: (A)

Inadequate cardiac output refers to the heart's inability to pump enough blood to meet the body’s needs, which can lead to various clinical signs. Poor peripheral circulation is a key indicator of this condition. When cardiac output is insufficient, the blood flow to the extremities may decrease, leading to signs such as cool, pale, or mottled skin, weakness, and a delayed capillary refill time.

This outcome occurs because the body prioritizes vital organs over extremities during times of reduced blood flow, resulting in inadequate perfusion to peripheral tissues. Monitoring peripheral circulation is crucial for telemetry monitor technicians as it provides immediate insight into a patient’s volume status and overall cardiovascular health.
