A nurse is collecting data from a client who has left-sided heart failure. For which of the following findings should the nurse notify the provider?

A. "Productive cough with pink, frothy sputum": This is a concerning finding that should prompt immediate notification to the provider. It is indicative of pulmonary edema, which can occur with left-sided heart failure as fluid backs up into the lungs. Pink, frothy sputum is a classic sign of this condition and requires urgent intervention. B. "Weight loss of 1 kg (2.2 lB. in the past 24 hr": Weight loss is generally not a primary concern in left-sided heart failure. In fact, weight loss could be a result of fluid loss from diuretics or other interventions. A small weight change like this is not likely to be significant unless the client shows signs of dehydration or malnutrition. C. "Fatigue when ambulating 152 m (500 ft)": Fatigue with activity is common in clients with left-sided heart failure, as reduced cardiac output and impaired oxygenation of tissues can cause fatigue during exertion. However, this is not an acute finding that would require immediate intervention.
