In a client with heart failure and fluid overload, which lung assessment finding is most likely?

• A. Clear lungs
• B. Rales
• C. Wheezes
• D. Diminished breath sounds

Answer: (B)

Pulmonary edema from fluid overload increases hydrostatic pressure in the pulmonary capillaries, causing fluid to leak into the interstitial spaces and alveoli. Air moving through this fluid creates crackling sounds on auscultation, known as rales. This makes rales the most likely lung finding in a client with heart failure and fluid overload. Clear lungs would suggest no edema, diminished breath sounds point to other issues like effusion or airway loss, and wheezes indicate airway constriction rather than edema.
