What vital sign indicates Sara Simpson is experiencing shock?

• A. High heart rate
• B. High blood pressure
• C. Normal respiratory rate
• D. Low oxygen saturation

Answer: (A)

A high heart rate is a significant indicator that a patient like Sara Simpson may be experiencing shock. When the body is in shock, it often compensates for inadequate perfusion by increasing the heart rate to maintain blood flow to vital organs. This increased heart rate, known as tachycardia, reflects the physiological response to stress and is part of the body's attempt to meet its metabolic needs despite compromised circulation. High blood pressure would not typically indicate shock; rather, it may suggest the opposite or could be a sign that the body is potentially compensating, at least initially. A normal respiratory rate does not align with shock, as respiratory patterns often change in response to various forms of shock, leading to either increased rates or labored breathing. Low oxygen saturation could indicate hypoxemia or respiratory distress but is not a direct indicator of shock on its own without considering the overall clinical picture, including heart rate and blood pressure. In summary, the elevated heart rate is a key sign of shock as it demonstrates the body's compensatory mechanisms responding to decreased perfusion or blood volume.
