Which of the following would best indicate that a patient is not receiving adequate perfusion?

• A. Resting tachycardia
• B. Warm, flushed skin
• C. Normal capillary refill
• D. Clear mental status

Answer: (A)

When tissue perfusion is inadequate, the body compensates by increasing heart rate to push blood more quickly to organs. Resting tachycardia is a direct sign that the circulation is under stress and the heart is working harder to maintain blood flow, making it the best indicator among the options. In contrast, warm, flushed skin can occur with good perfusion or other factors like heat or fever; normal capillary refill suggests adequate peripheral perfusion; and clear mental status indicates the brain is currently receiving enough blood, though mental status can be influenced by other conditions. Therefore, resting tachycardia most clearly signals not enough perfusion.
