The nurse is conducting an assessment of a client that has been admitted to a medical unit in the hospital for treatment of pneumonia. Which action will the nurse take when conducting the respiratory assessment of this client?

The correct answer is B: Auscultate the chest for breath sounds. This is the appropriate action because assessing breath sounds is crucial in evaluating respiratory function, especially in a client with pneumonia. Abnormal breath sounds can indicate underlying lung pathology, such as consolidation or effusion. Documenting "impaired oxygenation" (A) is premature without a thorough assessment. Collaborating with the client to form goals (C) is important but not the immediate priority. Applying supplemental oxygen (D) is a potential intervention after assessing breath sounds.
