Which of the following is NOT a sign of shock from a ruptured aneurysm?

In the context of shock resulting from a ruptured aneurysm, it is important to recognize the physiological responses that occur as the body attempts to compensate for decreased blood volume and perfusion. Signs of shock typically include tachycardia (increased heart rate), altered mental status (decreased level of consciousness), and hypotension (low blood pressure), all of which reflect the body's struggle to maintain adequate blood flow and oxygen to vital organs.

Elevated blood pressure, on the other hand, is not consistent with the signs of shock caused by a ruptured aneurysm. In fact, one would expect blood pressure to drop due to significant blood loss and resultant hypovolemia experienced in this scenario. As the body loses blood, the compensatory mechanisms will often lead to an increase in heart rate in an attempt to circulate the remaining blood more rapidly and a decrease in blood pressure, presenting clear signs of shock.

Therefore, elevated blood pressure is not a characteristic typically associated with shock from a ruptured aneurysm, making it the correct choice in this context.
