The nurse is admitting a client with possible tuberculosis (TB). The client is placed in a private room with airborne precautions pending diagnostic test results. Which diagnostic test should the nurse review to confirm the diagnosis of TB?
Chest X-ray or computed tomography (CT).
Hemoccult test on sputum collected from hemoptysis.
Positive purified protein derivative (PPD) skin test.
Sputum culture positive for Mycobacterium tuberculosis.
The Correct Answer is D
Choice A rationale
A chest X-ray or computed tomography (CT) scan can show abnormalities in the lungs that are suggestive of tuberculosis (TB), but they cannot definitively diagnose TB. These imaging tests can reveal changes in the lungs, such as nodules, inflammation, or fluid buildup, which can be caused by TB or other conditions. Therefore, a chest X-ray or CT scan alone is not sufficient to diagnose TB.
Choice B rationale
A hemoccult test on sputum collected from hemoptysis is not a diagnostic test for TB. It is a test for blood in the stool, which can be a symptom of TB but is not specific to TB. Hemoptysis, or coughing up blood, can occur in various conditions, including bronchitis, pneumonia, lung cancer, and TB. The hemoccult test cannot differentiate between these causes, making it an unreliable test for diagnosing TB.
Choice C rationale
A positive purified protein derivative (PPD) skin test indicates exposure to TB but does not confirm active infection. The PPD skin test involves injecting a small amount of tuberculin, a protein derived from Mycobacterium tuberculosis, into the skin. If a person has been exposed to TB, their immune system will react to the tuberculin, causing a raised red bump to appear at the injection site. However, a positive PPD skin test does not necessarily mean that a person has active TB infection. It could also mean that they have been exposed to TB in the past but have successfully fought off the infection. Further testing, such as a sputum culture, is needed to confirm the diagnosis of TB.
Choice D rationale
A sputum culture positive for Mycobacterium tuberculosis is the definitive diagnostic test for TB. It involves collecting a sample of sputum, which is the mucus coughed up from the lungs, and culturing it in a laboratory to see if Mycobacterium tuberculosis, the bacteria that causes TB, grows. This test is highly specific for TB, meaning that a positive result is almost always indicative of TB infection. It is also sensitive, meaning that it can detect TB infection even when there are few bacteria present.

Correct Answer is A
Explanation
Choice A rationale
Tiotropium is a long-acting bronchodilator used daily to manage chronic obstructive pulmonary disease (COPD). It helps to relax the muscles around the airways, making it easier to breathe. This medication is not intended for immediate relief of acute symptoms but for long-term control of COPD1.
Choice B rationale
Using another inhaler in between uses of tiotropium is not necessary unless prescribed by a healthcare provider. Tiotropium is meant to be used daily, and other inhalers may be prescribed for different purposes, such as rescue inhalers for sudden symptoms.
Choice C rationale
While tiotropium can help improve breathing and reduce symptoms over time, it is not specifically indicated to reduce the thickness of sputum. Other medications or treatments may be needed to address sputum consistency.
Choice D rationale
Tiotropium is not a rescue inhaler and should not be used for sudden shortness of breath. Rescue inhalers, such as albuterol, are designed for immediate relief of acute symptoms.
Correct Answer is A
Explanation
Choice A rationale
Isolating the client from others is the most important action to prevent the spread of COVID-19. This includes isolating the client from other clients, family, and healthcare workers not wearing proper PPE2.
Choice B rationale
Reporting the COVID-19 result to the local health department is important but not the immediate priority. Isolation takes precedence to prevent transmission.
Choice C rationale
Teaching the client to wear a mask, hand wash, and social distance is essential but secondary to immediate isolation.
Choice D rationale
Counseling family members to monitor for symptoms is important but not the immediate priority. Isolation of the client is the first step.
