Step-by-step explanation:
Specimens for Diagnostic Analysis of Unresolved Cough with Mucus Production
When a patient has an unresolved cough with mucus production, sputum is the indicated specimen for diagnostic analysis. Sputum, or phlegm, is the mucus and other substances that are expelled from the respiratory tract during coughing. It can be collected and examined to identify potential pathogens or underlying conditions causing the cough.
Blood, stool, and urine specimens are not directly indicated for the diagnostic analysis of an unresolved cough with mucus production, as they do not provide relevant information about the respiratory system or the presence of respiratory infections.
