A patient with severe blood loss has cool, pale skin and a weak rapid pulse. Which cardiovascular change is the nurse most likely to find?
Correct answer: B. Reduced venous return and reduced cardiac output
- A. Increased venous return and increased stroke volume
- B. Reduced venous return and reduced cardiac output
- C. Reduced heart rate and increased cardiac output
- D. Increased capillary filtration and increased blood pressure
Explanation
Blood loss reduces circulating volume, so less blood returns to the heart and cardiac output falls. The weak rapid pulse is a compensatory response, while the cool pale skin reflects peripheral vasoconstriction and reduced skin perfusion.

About Cardiovascular System
The cardiovascular system covers the chambers, valves and major vessels of the heart, the cardiac cycle, conduction pathway, blood pressure and the circulation through pulmonary and systemic circuits. It also explains artery, vein and capillary structure, exchange at capillary beds, and how the cardiac cycle differs from general blood flow.
