Which of the following is an early sign of congestive heart failure that the nurse should recognize?

Rationale: A. Bradycardia is not an early sign of congestive heart failure; tachycardia is more common. B. Tachypnea (rapid breathing) is an early indicator of congestive heart failure in children, reflecting pulmonary congestion and decreased cardiac output. C. Urine output usually decreases, not increases, due to poor renal perfusion. D. Inability to sweat is not associated with congestive heart failure; sweating may actually increase due to sympathetic activation.
