A patient with a history of asthma enters the Emergency department with severe dyspnea, accessory muscle involvement, neck vein distention, and severe inspiratory/expiratory wheezing. The nurse should prepare to assist the physician with which procedure if the patient does not respond to initial interventions?
Emergency needle thoracentesis
Emergency intubation
Emergency pleurodesis
Emergency chest tube insertion
The Correct Answer is B
A. Needle thoracentesis is typically performed in cases of pneumothorax or pleural effusion, not asthma exacerbation. The symptoms described do not indicate a pleural space issue that would require thoracentesis.
B. Emergency intubation may be necessary if the asthma exacerbation is severe and unresponsive to initial interventions such as bronchodilators, corticosteroids, and oxygen therapy. The patient's symptoms of severe dyspnea, accessory muscle use, and wheezing suggest respiratory distress, and intubation may be required to secure the airway and assist with ventilation.
C. Pleurodesis is a procedure used to treat recurrent pleural effusions, not asthma exacerbations. It involves the obliteration of the pleural space, which is not relevant to the current situation.
D. Chest tube insertion is typically performed for pneumothorax or other issues involving the pleural space, not for asthma exacerbation. The described symptoms do not suggest the need for a chest tube.

Correct Answer is B
Explanation
A. Bacteria are not typically detected by a guaiac stool test. Bacterial infections may be diagnosed with a stool culture or other microbiological tests.
B. The guaiac stool test is used to detect hidden (occult) blood in the stool, which can be a sign of gastrointestinal bleeding, such as from ulcers, polyps, or cancer.
C. Steatorrhea refers to the presence of excess fat in the stool, which can be detected by other tests, such as fecal fat analysis, not a guaiac test.
D. Parasites are usually detected through stool microscopy or stool ova and parasite (O&P) tests, not a guaiac test.
Correct Answer is D
Explanation
A. Cyanosis is a common feature in both chronic bronchitis and emphysema due to hypoxemia, but it is more often seen in chronic bronchitis due to the persistent airway obstruction and reduced gas exchange.
B. Dyspnea (shortness of breath) is more commonly associated with emphysema due to the destruction of alveolar walls and loss of lung elasticity, which impairs gas exchange. Chronic bronchitis can also cause dyspnea, but it is more closely linked with emphysema.
C. Lymphadenopathy is not a characteristic feature of chronic bronchitis or emphysema; it is more associated with infections or malignancies.
D. Chronic bronchitis is characterized by a persistent cough with sputum production, which is a hallmark symptom. This is more prominent in chronic bronchitis than in emphysema, where the cough is less frequent and sputum production is less significant.
