Final answer:
The respiratory manifestations of heart failure that a nurse will monitor include Orthopnea, Exertional dyspnea, and Cheyne-Stokes respiration.
Step-by-step explanation:
The nurse will monitor the following respiratory manifestations of heart failure: b) Orthopnea, which is difficulty breathing when lying flat; c) Exertional dyspnea, which is difficulty breathing during physical activity; and d) Cheyne-Stokes respiration, an abnormal pattern of breathing characterized by progressively deeper and sometimes faster breathing, followed by a gradual decrease that results in a temporary stop in breathing called an apnea. Although a chronic dry cough and hyperventilation could be associated with respiratory conditions, they are not as directly correlated with heart failure as the selected manifestations. It is worth noting that Cheyne-Stokes respiration can be observed in advanced stages of heart failure.
