The patient’s vital signs are as follows: Temperature 97.5 F (36.4 C), Heart rate 104 beats/minute, Respirations 29 breaths/minute, Blood pressure 119/82 mm Hg, Oxygen saturation 89%. Oxygen mask applied.
What should the nurse do next?

Choice A rationale:

Lactulose directly addresses the primary cause of hepatic encephalopathy, which is the accumulation of ammonia in the blood. Ammonia is a neurotoxin that can impair brain function, leading to confusion, lethargy, and even coma. Lactulose works by trapping ammonia in the colon, where it can be safely excreted in the stool. This decrease in ammonia levels in the blood allows for the improvement of mental status.

Studies have consistently shown that lactulose therapy can significantly improve mental function in patients with hepatic encephalopathy. This improvement is often seen within a few days of starting treatment.

The nurse should assess the client's mental status regularly to monitor for improvement. This assessment should include evaluating the client's level of consciousness, orientation, attention, memory, and speech.

Improved mental status is a critical therapeutic goal in the treatment of hepatic encephalopathy. It allows patients to regain their independence and participate more fully in their care.

Choice B rationale:

While lactulose can cause diarrhea, which may lead to a slight increase in urine output, this is not the primary therapeutic response that the nurse should expect.

The increase in urine output is typically secondary to the diarrhea and does not directly reflect a reduction in ammonia levels or improvement in mental status.

Choice C rationale:

Lactulose does cause diarrhea, which is a common side effect of the medication.

However, the goal of lactulose therapy is not to reduce the number of liquid stools but rather to trap ammonia in the colon and promote its excretion.

The nurse should monitor the client's stool frequency and consistency to ensure that they are not experiencing excessive diarrhea, which could lead to dehydration and electrolyte imbalances.

Choice D rationale:

While improved mental status may eventually lead to improved mobility, it is not the most immediate or direct therapeutic response that the nurse should expect from lactulose therapy.

The ability to ambulate independently is more likely to be a long-term goal of treatment, rather than an immediate response to lactulose.

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.
