A patient with cholelithiasis has a gallstone lodged in the common bile duct and is unable to eat or drink without becoming nauseated and vomiting.

Which finding should the nurse report to the healthcare provider?

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.

Choice A rationale:

Maintains airway patency: Leaving the old ties in place until the new ones are secure ensures that the tracheostomy tube remains in the correct position and prevents accidental decannulation, which could obstruct the airway and lead to respiratory distress or arrest. This is the most important priority in tracheostomy care.

Prevents tube displacement: Accidental decannulation can occur during tie changes, especially in patients with copious secretions or who are restless or agitated. Keeping the old ties in place acts as a safety measure to keep the tube in position even if the new ties are not immediately secured.

Allows for adjustments: If the new ties are not tied correctly or are too tight, the old ties can be loosened or removed to make adjustments without compromising the airway.

Minimizes anxiety: Leaving the old ties in place can help to reduce anxiety in patients who are apprehensive about the tie- changing process, as it provides a sense of security and ensures that the tube will not be dislodged.

Choice B rationale:

Increases risk of skin irritation: Knots tied close to the tube can rub against the skin, causing irritation, discomfort, and potential skin breakdown, especially in patients with sensitive skin or who have copious secretions.

Impinges on blood flow: Tight knots can also constrict blood vessels, potentially impairing circulation to the skin around the tracheostomy site.

Difficult to remove in emergencies: Knots tied too close to the tube can be challenging to untie quickly in case of an emergency, such as accidental decannulation or the need to suction secretions.

Choice C rationale:

Not appropriate for all patients: Disposable, soft foam collars with self-adhesive fastening may not be suitable for patients with copious secretions, as the adhesive may not adhere well to moist skin.

May not provide adequate support: These collars may not provide the same level of support as traditional tracheostomy ties, especially in patients with active neck movement or who are at risk of accidental decannulation.

Potential for skin irritation: The adhesive on the collar can also irritate the skin around the tracheostomy site in some patients.

Choice D rationale:

May not prevent irritation: Placing knots laterally may not completely eliminate the risk of skin irritation, as the ties can still rub against the skin with neck movement or when the patient is lying down.

Could lead to accidental loosening: Knots tied laterally may be more prone to accidental loosening, especially if the patient is restless or agitated.
