Assessing and managing the underlying cause of respiratory failure

Administering sedatives and paralytics without assessing pain levels

Answer and Explanation

Correct Answer : A,B,C,D

Mechanical ventilation is used to support or replace spontaneous breathing in clients with respiratory failure. Safe and effective management requires not only maintaining adequate oxygenation and ventilation but also preventing complications such as ventilator-associated pneumonia, pressure injuries, malnutrition, and prolonged sedation. Care is multidisciplinary and includes weaning readiness assessments, skin integrity protection, treatment of the underlying cause of respiratory failure, and metabolic support.

Rationale:
A. Conducting spontaneous awakening and breathing trials as prescribed is essential because it helps assess readiness for weaning from mechanical ventilation. These trials reduce sedation and evaluate the client’s ability to breathe independently. They decrease ventilator dependence and improve outcomes by promoting earlier extubation when appropriate.

B. Frequent repositioning to prevent pressure ulcers is necessary because immobility during mechanical ventilation increases the risk of skin breakdown. Regular turning improves circulation, reduces prolonged pressure on bony prominences, and prevents pressure injuries. It also supports lung expansion and helps reduce the risk of ventilator-associated pneumonia.

C. Assessing and managing the underlying cause of respiratory failure is a priority because mechanical ventilation is supportive rather than curative. Treating the root cause—such as pneumonia, sepsis, or trauma—improves the likelihood of recovery and successful weaning. Without addressing the underlying condition, respiratory failure may persist or worsen.

D. Providing nutritional support due to increased metabolic demands is essential because mechanically ventilated clients often experience a hypermetabolic state. Adequate nutrition supports immune function, tissue repair, and respiratory muscle strength. Enteral feeding is preferred when possible to maintain gut integrity and reduce infection risk.

E. Administering sedatives and paralytics without assessing pain levels is unsafe and incorrect practice. Sedation and neuromuscular blockade should be carefully titrated based on ongoing assessment of pain, comfort, and ventilator synchrony. Over-sedation can delay weaning, mask complications, and increase the risk of prolonged mechanical ventilation.

Correct Answer is A

Explanation

A chest tube drainage system is used to remove air, blood, or fluid from the pleural space and restore negative intrathoracic pressure. Continuous bubbling in the water seal chamber indicates an air leak in the system. Identifying and correcting the source of the leak is essential to maintain effective lung re-expansion and prevent complications such as tension pneumothorax. Nursing interventions focus on systematically locating the leak starting from the patient site moving toward the drainage system.

Rationale:
A. Reinforcing the dressing at the connection between the chest tube and drainage system tubing is the priority action because persistent bubbling after clamping near the dressing suggests a leak at or near the insertion site or tubing connection. This area is a common source of air leaks. Securing and reinforcing the connection helps restore system integrity and prevents further air entry into the pleural space.

B. Stripping the tube is not recommended because it can create excessively negative pressure within the pleural space. This may lead to tissue trauma, bleeding, or re-expansion pulmonary edema. Current best practice discourages routine stripping or milking of chest tubes as it can worsen patient outcomes rather than resolve air leaks.

C. Checking for kinks in the tubing is an appropriate general assessment, but it does not address the specific finding of continuous bubbling after clamping near the insertion site. Kinks typically result in impaired drainage or lack of fluctuation rather than persistent air leak. Since bubbling continues, the issue is more likely a loose connection or insertion site leak.

D. Disconnecting the chest tube from the drainage system is unsafe and contraindicated. This action can introduce air directly into the pleural space, worsening the pneumothorax and potentially causing tension pneumothorax. Any suspected disconnection should be corrected using sterile technique rather than separating the system entirely.

A. A client who is postoperative and has received local anesthesia B. A massive stroke client who has dysphagia C. A client who has myasthenia gravis D. A client who has AIDS E. A client who has a closed head injury and is receiving mechanical ventilation F. A client who was vaccinated for pneumococcus and influenza 6 months ago

Correct Answer is ["B","C","D","E"]

Explanation

Ventilator-associated pneumonia (VAP) is a hospital-acquired infection that develops in patients who are mechanically ventilated for more than 48 hours. It occurs due to impaired airway defenses, aspiration of contaminated secretions, and colonization of the respiratory tract. Risk increases in clients with reduced level of consciousness, impaired swallowing, neuromuscular weakness, immunosuppression, and prolonged ventilation. Identifying high-risk patients is essential for implementing preventive measures such as oral care, elevation of the head of the bed, and suctioning protocols.

Rationale:
A. A postoperative client who has received local anesthesia is not at increased risk for ventilator-associated pneumonia because they are not typically mechanically ventilated or experiencing impaired airway protective reflexes. Local anesthesia does not significantly affect consciousness or swallowing ability, so aspiration risk remains low compared to ventilated or neurologically impaired patients.

B. A massive stroke client with dysphagia is at high risk for VAP due to impaired swallowing and reduced gag reflex. These deficits increase the likelihood of aspiration of oral or gastric contents into the lungs, which can lead to infection, especially if the client is intubated or requires mechanical ventilation.

C. A client with myasthenia gravis is at increased risk because neuromuscular weakness can impair respiratory muscle function and cough effectiveness. This condition often leads to respiratory failure requiring mechanical ventilation, which significantly increases the risk of ventilator-associated pneumonia due to secretion retention and impaired airway clearance.

D. A client with AIDS is at increased risk due to immunosuppression, which reduces the body’s ability to fight respiratory infections. Opportunistic pathogens can more easily colonize the respiratory tract, especially in ventilated patients, making VAP more likely and more severe in this population.

E. A client with a closed head injury receiving mechanical ventilation is at high risk because of reduced consciousness, impaired cough reflex, and prolonged ventilator dependence. These factors promote aspiration and bacterial colonization of the lower respiratory tract, significantly increasing the likelihood of developing VAP.

F. A client vaccinated for pneumococcus and influenza 6 months ago is not specifically at increased risk for VAP due to vaccination status. While vaccines help prevent certain respiratory infections, they do not eliminate the risk of hospital-acquired infections related to mechanical ventilation and airway management.
