A client who has had a laryngectomy and tracheostomy frequently expectorates copious amounts of purulent secretions.
When changing the ties of the tracheostomy tube, which action is most important for the nurse to take?

Leave the old ties in place until the new ones are secure.

Secure tracheostomy ties by making knots close to the tube.

Remove ties to secure a disposable, soft foam collar with self-adhesive fastening.

Place knots of the ties laterally to prevent irritation and pressure.

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is C

Explanation

Choice A rationale:

Carbon dioxide is primarily eliminated through the lungs, not the kidneys. While the kidneys do play a role in acid-base balance, their primary mechanism for regulating pH is through the excretion or retention of bicarbonate ions (HCO3-), not carbon dioxide itself.

The kidneys' ability to compensate for respiratory acidosis is limited. In cases of severe respiratory acidosis, the kidneys may not be able to adequately compensate, leading to a further decrease in blood pH.

Choice B rationale:

Hyperventilation would actually decrease carbon dioxide levels in the blood, not increase them. Hyperventilation is a state of rapid, deep breathing that leads to increased exhalation of carbon dioxide. This can result in respiratory alkalosis, which is the opposite of respiratory acidosis.

Choice D rationale:

Low blood oxygen levels (hypoxia) can stimulate respiration, but this would not directly cause respiratory acidosis. In fact, hypoxia can sometimes lead to respiratory alkalosis due to hyperventilation.

Respiratory acidosis is primarily caused by impaired carbon dioxide elimination, not decreased oxygen levels.

Choice C rationale:

High levels of carbon dioxide in the blood (hypercapnia) are the hallmark feature of respiratory acidosis. This can occur due to a variety of factors that impair ventilation, such as:

Chronic obstructive pulmonary disease (COPD) Asthma

Pneumonia Sleep apnea

Neuromuscular disorders that affect breathing Drug overdose (e.g., opioids)

The accumulation of carbon dioxide in the blood leads to a decrease in blood pH, which can have a range of negative effects on the body's organ systems.

A. Increase the daily intake of oral fluids to liquefy secretions. B. Call the clinic if undesirable side effects of medications occur. C. Teach anxiety reduction methods for feelings of suffocation. D. Avoid crowded enclosed areas to reduce pathogen exposure.

Correct Answer is A

Explanation

Choice A rationale:

Liquefying secretions is the most crucial action to address the client's immediate respiratory concerns. Thickened mucus obstructs airflow, leading to shortness of breath, productive cough, and difficulty breathing upon exertion. Increasing fluid intake thins mucus, making it easier to expel and improving ventilation. This directly addresses the client's current symptoms and promotes airway clearance.

Hydration and Mucociliary Clearance: Adequate hydration is indispensable for optimal mucociliary clearance, the natural mechanism that removes mucus from the airways. Fluids moisten the respiratory tract, allowing cilia (tiny hair-like structures) to effectively move mucus upwards, where it can be coughed out or swallowed.

Thinning Mucus: Water acts as a natural expectorant, thinning mucus and reducing its viscosity. This makes it easier for the client to cough up the mucus, clearing the airways and reducing the sensation of breathlessness.

Decreasing Mucus Production: Dehydration can trigger the body to produce more mucus as a protective response. By staying hydrated, the client can help prevent excessive mucus production, further easing symptoms.

Supporting Overall Respiratory Health: Proper hydration maintains the health of the respiratory system's tissues and cells, promoting efficient gas exchange and reducing inflammation.

Preventing Dehydration-Related Complications: Dehydration can exacerbate respiratory problems and lead to other complications, such as fatigue, headaches, and impaired immune function. Maintaining adequate fluid intake helps prevent these issues.

Key points to emphasize to the client:

Drink fluids throughout the day, even if not feeling thirsty.

Water is the best choice, but clear broths, juices, and herbal teas can also contribute to fluid intake. Avoid caffeine and alcohol, as they can be dehydrating.

Monitor urine output to ensure adequate hydration (urine should be pale yellow or clear).

Increase fluid intake during periods of increased mucus production, such as during respiratory infections or exercise.
