Which of the following is a sign of cardiogenic shock?

In cardiogenic shock, the heart is unable to pump blood effectively, which leads to inadequate circulation and oxygen delivery to the body's tissues. One of the primary indicators of this condition is low blood pressure. When the heart struggles to maintain an adequate cardiac output, peripheral blood vessels can constrict to compensate, but this often results in reduced overall blood pressure. Consequently, low blood pressure is a prominent sign indicating that the heart is failing to meet the circulatory demands of the body.

Other symptoms associated with cardiogenic shock might include signs of poor perfusion, such as altered mental status or cold, clammy skin, but low blood pressure is one of the key vital signs that directly reflects the decreased pumping capability of the heart in this critical situation.
