Reyes FM, Modi P, Le JK. The nurse suspects further testing will lead to which diagnosis? Occurs due to increased density within the lung parenchyma. If anything abnormal is detected during an exam, your doctor will look for other signs that might point to a pulmonary disorder or another health issue. Many diseases and conditions can cause abnormal breath sounds. Put a pulse oximeter on the patient's finger. zus_Y2NW:EP\v?_@`t7m+'_W[~}c#]ZWYn.C?DZ_Z =a%>lzJ)~+m803 5JJm}t[;yARO\jO "Is caused by moisture in the alveoli." b. While auscultating the chest, the nurse asks the patient to phonate a long "ee-ee-ee-ee" sound. A stethoscope is useful because it helps magnify internal sounds, but an ear pressed closely to the skin can provide a lot of information when a stethoscope is not available. The following changes in vocal resonance are seen. endobj Rhonchial fremitus often identified during inhalation and exhalation may clear if the patient produces an effective cough. Does this patient have a pleural effusion? why is there dullness on percussion then? Please enable it to take advantage of the complete set of features! Somewhere, I was led to associate decreased tactile fremitus with atelectasis and increased with pneumonia and tumors. Obstructive atelectasis is the most common and results from obstruction of the bronchi between the alveoli and the trachea.
