Which age-related changes in the respiratory system cause decreased secretion clearance? (Select all that apply.)

The nurse would prepare the patient for a thoracentesis, which is the diagnostic procedure used to remove pleural fluid for analysis. This test helps determine the cause of pleural effusion, such as infection, malignancy, or inflammatory conditions, and can also relieve pressure on the lungs caused by excess fluid accumulation.

Rationale for correct answer:
1. Thoracentesis. Thoracentesis involves inserting a needle into the pleural space between the chest wall and the lungs to withdraw pleural fluid for diagnostic or therapeutic purposes. The fluid is analyzed for cell count, protein, glucose, culture, and cytology to identify infection, cancer, or other causes of pleural effusion. The procedure also helps alleviate symptoms such as dyspnea by reducing lung compression.

Rationale for incorrect answers:
2. Bronchoscopy. A bronchoscopy involves inserting a flexible tube through the nose or mouth into the bronchi to directly visualize the airways, obtain tissue biopsies, or remove secretions. It does not involve removal of pleural fluid from the pleural space.
3. Pulmonary angiography. This test involves injecting contrast dye into the pulmonary arteries to evaluate blood flow and detect pulmonary embolism or vascular abnormalities. It is not used for fluid removal or pleural fluid analysis.
4. Sputum culture and sensitivity. A sputum test analyzes mucus expectorated from the lungs to identify microorganisms causing infection, such as pneumonia or tuberculosis. It evaluates airway secretions, not pleural fluid from the pleural cavity.

Take-home points:

• Thoracentesis is the correct procedure for removing and analyzing pleural fluid.
• The test helps diagnose infection, malignancy, or inflammatory causes of pleural effusion.
• The nurse should position the patient upright and leaning forward, monitor for respiratory distress, and obtain a post-procedure chest x-ray to rule out pneumothorax.
• Other respiratory tests like bronchoscopy, angiography, or sputum culture serve different diagnostic purposes and do not access the pleural space.

When assessing activity–exercise patterns related to respiratory health, the nurse should inquire about dyspnea during rest or exercise. This information helps determine how well the patient’s respiratory system meets oxygen demands during physical activity and identifies early signs of respiratory compromise.

Rationale for correct answer:
1. Dyspnea during rest or exercise. Asking about shortness of breath (dyspnea) during physical activity or even at rest provides valuable data on the patient’s functional respiratory capacity. The severity and onset of dyspnea help the nurse assess disease progression, tolerance to activity, and the need for interventions such as pacing, oxygen therapy, or pulmonary rehabilitation. This assessment directly reflects the patient’s ability to meet metabolic demands through adequate ventilation.

Rationale for incorrect answers:
2. Recent weight loss or weight gain. Although changes in weight can provide important information about overall health and nutrition, they are not specific to activity–exercise patterns. Weight changes may indicate metabolic or cardiac issues rather than directly assessing respiratory function.
3. Ability to sleep through the entire night. This relates more to the sleep–rest pattern than to the activity–exercise pattern. While nighttime breathing difficulties (e.g., orthopnea) are important, they are assessed under a different functional health category.
4. Willingness to wear oxygen equipment in public. This question addresses the patient’s coping and self-concept rather than their activity–exercise pattern. Although it may influence treatment adherence, it does not evaluate respiratory tolerance to physical activity.

Take-home points:

• Dyspnea during activity or rest is the most relevant indicator when assessing activity–exercise patterns in respiratory health.
• Evaluating tolerance to exertion helps determine disease severity and functional limitations.
• Other aspects, such as sleep, nutrition, or coping, fall under separate health pattern assessments but remain important for holistic care.
