A client presents to the emergency department with muscle aches, headache, fever, and describes a recent loss of taste and smell.
The nurse obtains a nasal swab for COVID-19 testing. Which action is most important for the nurse to take?

Choice A rationale:

Tiotropium is a long-acting bronchodilator, not a rescue inhaler for sudden shortness of breath.

It takes several hours to reach its full effect and is not designed to provide immediate relief during acute symptoms.

Using tiotropium for sudden shortness of breath could delay the use of a more appropriate rescue medication, potentially worsening the situation.

Choice B rationale:

While tiotropium can help reduce mucus production and make secretions easier to clear, this is not its primary mechanism of action.

The client's statement focuses on a potential side effect rather than demonstrating a clear understanding of the medication's intended purpose.

Choice C rationale:

The frequency of inhaler use depends on the specific medications prescribed. Some inhalers are used daily, while others are used only as needed for symptoms.

It's essential to follow the healthcare provider's instructions for each inhaler to ensure proper use and avoid potential drug interactions.

Choice D rationale:

This statement correctly reflects the appropriate use of tiotropium.

It's typically taken once daily via a handihaler device to maintain open airways and prevent COPD symptoms. Regular daily use is crucial for optimal effectiveness.

Choice A rationale:

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 B rationale:

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.

Choice C rationale:

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:

Chest X-ray or computed tomography (CT) can show abnormalities in the lungs that are suggestive of 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. A sputum culture is still needed to confirm the diagnosis.
