Increased fremitus while palpating the posterior thorax suggests that C) the client could either have fluid in the lungs or an infection.
When a nurse detects heightened fremitus during palpation of the posterior thorax, it indicates increased vibrations or tactile fremitus. This can occur due to conditions like pneumonia, where consolidation of lung tissue or the presence of fluid increases the transmission of vibrations.
It's a valuable clinical indicator prompting further investigation for possible respiratory issues. This finding warrants a comprehensive assessment, including auscultation and potentially other diagnostic tests, to accurately determine the underlying cause. Addressing the potential presence of fluid in the lungs or an infection is crucial for appropriate intervention and treatment to support the client's respiratory health.
Therefore the correctoption is C.
