Question

What are the physiologic signs and symptoms of cardiogenic shock? (Select all that apply.)

a) Increased urine output related to increased renal perfusion
b) Rise in central venous pressure (CVP)
c) Increased extraction of O2 from hemoglobin
d) Decrease in mean arterial blood pressures
e) Hypercapnic lips and nail beds

Answer 1

The physiologic signs and symptoms of cardiogenic shock include a rise in central venous pressure, a decrease in mean arterial blood pressure, and increased extraction of oxygen from hemoglobin.

Step-by-step explanation:

The physiologic signs and symptoms of cardiogenic shock include:

1. Rise in central venous pressure (CVP): In cardiogenic shock, the damaged heart cannot pump blood effectively, leading to a rise in central venous pressure.
2. Decrease in mean arterial blood pressure: The reduced cardiac output results in a decrease in mean arterial blood pressure.
3. Increased extraction of O2 from hemoglobin: The body compensates for decreased cardiac output by extracting more oxygen from hemoglobin.

Therefore, the correct options are b) Rise in central venous pressure (CVP), d) Decrease in mean arterial blood pressures, and c) Increased extraction of O2 from hemoglobin.
