The nurse is gathering data on a client with a diagnosis of tuberculosis. The nurse should review the results of which diagnostic test to confirm this diagnosis?

Sputum culture

Chest x-ray

Tuberculin skin test

Bronchoscopy

Answer and Explanation

The Correct Answer is A

A. Sputum culture: A sputum culture is the definitive diagnostic test for tuberculosis (TB). It involves collecting a sample of the patient’s sputum and testing it for the presence of Mycobacterium tuberculosis, the bacterium that causes TB. This test confirms active TB infection and is critical in guiding treatment.

B. Chest x-ray: A chest x-ray can show abnormalities in the lungs that may suggest TB, such as infiltrates or cavities, but it cannot confirm the diagnosis. It is often used as a supporting diagnostic tool alongside other tests.

C. Tuberculin skin test: The tuberculin skin test (TST) is used to identify latent TB infection, not active TB. A positive result indicates that a person has been exposed to TB bacteria, but it does not confirm active disease.

D. Bronchoscopy: Bronchoscopy allows for direct visualization of the airways and collection of samples, but it is not the standard diagnostic test for confirming TB. Sputum culture remains the gold standard for diagnosis.

Correct Answer is A

Explanation

A. Expiratory wheeze: Wheezing, particularly on expiration, is a characteristic finding during an acute asthma exacerbation. It occurs due to the narrowing of the airways and turbulent airflow.

B. Rhonchi: Rhonchi are low-pitched, rattling sounds often caused by secretions in larger airways, not typically associated with asthma exacerbations.

C. Pleural friction rub: A pleural friction rub is a grating sound heard when the pleurae are inflamed, often seen in conditions like pleuritis, not asthma.

D. Fine rales: Fine rales, or crackles, are associated with fluid in the alveoli, often found in conditions like pneumonia or heart failure, rather than asthma

A. Nasal saline irrigation alone B. Oral decongestants alone C. Oral antibiotics D. Intranasal corticosteroids alone

Correct Answer is C

Explanation

In cases of acute bacterial sinusitis that last longer than 10 days, worsen after initial improvement, or present with severe symptoms (such as fever and significant facial pain), oral antibiotics are generally indicated. First-line options typically include amoxicillin-clavulanate.

Other options listed, such as nasal saline irrigation, oral decongestants, or intranasal corticosteroids, may help alleviate symptoms but would not address the bacterial infection, making antibiotics the most appropriate primary treatment in this case.
