Final answer:
Patients with right-sided heart failure often experience peripheral edema, leading to symptoms such as swollen feet and ankles, and may sleep in a chair or recliner to relieve breathing difficulty from fluid accumulation.
Step-by-step explanation:
The nurse caring for a client with suspected right-sided heart failure should be aware that this condition is often associated with specific symptoms such as peripheral edema, including swollen feet and ankles, abdominal distention due to ascites, jugular venous distention, and fatigue. One of the common experiences for patients with this condition is sleeping in a more upright position, such as in a chair or recliner, to relieve breathing difficulty caused by fluid accumulation. Thus, the correct answer is B. Sleeping in a chair or recliner. Gradual unexplained weight gain can also be a symptom due to fluid retention. However, increased perspiration and increased urine output are not typical symptoms of right-sided heart failure; they may be associated with other medical conditions.
