Crackles are an early sign of which condition?

Explanation:
Crackles indicate fluid overload in the lungs. They occur when fluid collects in the airways and tiny air sacs, causing air to pop open with each breath and producing a crackling sound. This pulmonary fluid is a hallmark of fluid overload, so crackles are an early clue to this condition. That’s why this option is the best answer. Rapid weight gain can accompany fluid overload but isn’t the direct lung sign crackles represent. Edema grading describes swelling in the extremities, not the lungs. Electrolyte imbalance causes other symptoms related to nerve and muscle function, not crackles in the lungs.
