After intubating a client, correct placement of the endotracheal tube (ETT) is confirmed with a chest x-ray. Which intervention should the nurse implement to ensure that the ETT placement is maintained?

A.

Oxygenate before suctioning.

B.

Auscultate bilateral breath sounds.

C.

Firmly secure the ETT in place.

D.

Suction the ETT every 2 hours.

Answer and Explanation

The Correct Answer is C

A. Oxygenate before suctioning. Pre-oxygenation before suctioning is essential to prevent hypoxia and bradycardia, but it does not directly ensure that the ETT remains in the correct position. This is a general airway management guideline rather than a specific intervention to maintain ETT placement.
B. Auscultate bilateral breath sounds. Auscultation is important for ongoing assessment of lung sounds and oxygenation but does not physically prevent tube displacement. While listening for equal breath sounds helps detect tube migration or mainstem bronchus intubation, it does not secure the ETT in place.
C. Firmly secure the ETT in place. After proper ETT placement is confirmed with a chest x-ray, securing the tube with adhesive tape or a commercial ETT holder prevents displacement. Unintentional extubation or tube migration can lead to hypoxia, respiratory distress, or esophageal intubation, making proper tube fixation a priority intervention.
D. Suction the ETT every 2 hours. Routine suctioning is not recommended unless there are indications such as visible secretions, high airway pressures, or decreased oxygenation. Frequent, unnecessary suctioning can cause mucosal trauma, hypoxia, and bradycardia and does not help maintain ETT placement.

Correct Answer is A

Explanation

A. Decreased cardiac output. Central venous pressure (CVP), also called right atrial pressure (RAP), reflects right ventricular preload and overall fluid status. An increasing CVP indicates fluid overload or impaired right ventricular function, both of which can lead to decreased cardiac output. Conditions such as right heart failure, pulmonary hypertension, or excessive fluid resuscitation can cause elevated CVP, reducing the heart’s ability to pump effectively and leading to poor systemic circulation.
B. Ineffective airway clearance. Airway clearance is not directly related to CVP measurements. While severe pulmonary conditions like ARDS or COPD can contribute to cardiac strain and right heart failure, the primary mechanism for rising CVP is cardiac dysfunction or fluid overload, not airway obstruction.
C. Ineffective peripheral tissue perfusion. Although decreased cardiac output can impair tissue perfusion, this choice is too broad. Increased CVP specifically reflects right-sided heart function and preload, making decreased cardiac output the more precise diagnosis related to the pathophysiologic mechanism.
D. Deficient fluid volume. A low CVP is associated with hypovolemia and fluid deficits, while an increasing CVP suggests fluid overload, heart failure, or venous congestion. Deficient fluid volume would cause a downward trend in CVP, not an increase.

Explanation

  • Increase the fraction of inspired oxygen (FiO₂). The client has severe COVID pneumonia and is on mechanical ventilation with high inspiratory pressures, suggesting acute respiratory distress syndrome (ARDS). Increasing FiO₂ is indicated if oxygenation is inadequate (e.g., low PaO₂ or SpO₂). However, oxygen toxicity should be avoided, so adjustments should be made based on arterial blood gases (ABGs) and oxygen saturation.
  • Collect equipment for a needle aspiration. Needle aspiration is typically used for pneumothorax management, but there is no mention of clinical signs such as sudden hypotension, absent breath sounds, or tracheal deviation. While ventilated COVID-19 patients are at risk for barotrauma, this procedure is not justified without evidence of pneumothorax.
  • Replace the ventilator. There is no indication that the ventilator is malfunctioning or that the settings are inappropriate. If ventilation issues arise (e.g., high plateau pressures, auto-PEEP, or ventilator asynchrony), adjustments to settings, sedation, or lung-protective strategies should be considered before replacing the ventilator.
  • Measure the nasogastric tube output. The client is intubated and sedated, meaning they cannot protect their airway or tolerate oral intake. A nasogastric (NG) tube is commonly placed for gastric decompression and feeding. Monitoring NG output is essential to assess for gastrointestinal bleeding, ileus, or high residual volumes, which can affect feeding tolerance.
  • Place the client in Trendelenburg. The Trendelenburg position increases the risk of aspiration, impairs lung expansion, and worsens ventilation-perfusion mismatch, especially in ARDS patients. Instead, prone positioning is often preferred in severe COVID pneumonia to improve oxygenation and alveolar recruitment.
