Rationale: Crackles in the lungs are indicative of fluid accumulation in the alveoli, which is a characteristic finding in clients with fluid volume excess.

Monitoring for crackles is essential for early detection and management of fluid overload in clients.

Bradycardia is more commonly seen in conditions like hypothyroidism or increased intracranial pressure. Increased skin turgor is a sign of dehydration, and hypertension is not a typical finding in fluid volume deficit.
