A nurse received a client who has had multiple episodes of pneumonia in the past year. What intervention is a PRIORITY for this client before starting treatment?

The correct answer is A: Sputum culture and sensitivity. This is crucial to identify the specific pathogen causing pneumonia and determine the most effective antibiotic treatment. It helps in targeting the infection accurately, reducing the risk of antibiotic resistance. Urinalysis (B) and a rapid Strep test (C) are not relevant for pneumonia diagnosis. While a Chest X-ray (D) is important for confirming pneumonia, identifying the pathogen through sputum culture takes precedence for tailored treatment.
