Final answer:
A nurse would identify congestion in the peripheral tissues as a symptom of right-sided heart failure, resulting from the right heart's incapacity to pump blood effectively through the lungs.
Step-by-step explanation:
The symptom that a nurse would identify as a manifestation of right-sided heart failure (HF) is congestion in the peripheral tissues. This occurs due to a rise in pressure in the vena cavae which leads to blood pooling and increased pressure in the systemic venous system. This congestion is a result of the right heart's inability to effectively pump blood through the lungs to be oxygenated, which consequently leads to fluid retention and swelling in the extremities, abdomen, and other organs.
