After an endotracheal tube (ETT) is initially placed for a client requiring mechanical ventilation, which intervention should the nurse implement first?

Obtain a chest x-ray to verify endotracheal tube location.

Call the respiratory therapist (RT) to verify tube placement.

Instill normal saline into the endotracheal tube for suctioning.

Auscultate for breath sounds bilaterally in all lung fields.

Answer and Explanation

The Correct Answer is D

A. Obtain a chest x-ray to verify endotracheal tube location. A chest x-ray is the gold standard for confirming ETT placement, but it is not the first step. Immediate bedside assessment is needed to ensure the tube is correctly positioned before relying on imaging. If the tube is misplaced in the esophagus, waiting for an x-ray could delay necessary corrections.
B. Call the respiratory therapist (RT) to verify tube placement. The nurse should first perform a rapid bedside assessment before consulting the RT. While RTs assist in confirming placement, the nurse is responsible for the initial verification of breath sounds, chest rise, and end-tidal CO₂ (ETCO₂) readings. Any concerns should be addressed immediately.
C. Instill normal saline into the endotracheal tube for suctioning. Instilling saline before suctioning is not recommended, as it can promote aspiration, decrease oxygenation, and increase infection risk. The priority is confirming that the tube is properly placed before performing any interventions such as suctioning.
D. Auscultate for breath sounds bilaterally in all lung fields. The first action after ETT placement is to auscultate bilateral breath sounds to confirm proper tube positioning. If the tube is misplaced in the esophagus, breath sounds will be absent or diminished bilaterally. If placed too deep, breath sounds may be absent on one side, indicating mainstem bronchus intubation. This immediate assessment helps identify misplacement before obtaining a chest x-ray.

Correct Answer is D

Explanation

A. Hyperglycemia. While elevated blood glucose can occur in acute pancreatitis due to pancreatic inflammation impairing insulin secretion, it is not an electrolyte imbalance. The question specifically asks about electrolyte-related manifestations.
B. Hypotension. Hypotension in acute pancreatitis is often due to fluid shifts (third-spacing) and systemic inflammation, rather than a direct electrolyte imbalance. Though dehydration and electrolyte losses can contribute to hypotension, this is not the most specific sign of an electrolyte disturbance.
C. Paralytic ileus and abdominal distention. Hypokalemia can lead to paralytic ileus, but ileus and distention are also caused by peritoneal irritation, inflammation, and impaired motility due to pancreatitis itself. While potassium imbalance could contribute, this is not the most direct electrolyte-related symptom.
D. Muscle twitching and digit numbness. Hypocalcemia is a common electrolyte imbalance in acute pancreatitis, caused by fatty acid breakdown binding calcium, leading to saponification. This results in neuromuscular excitability, causing muscle twitching, paresthesia (numbness/tingling), and positive Chvostek’s or Trousseau’s signs. These symptoms are clear indicators of an electrolyte disturbance related to pancreatitis.

A. Increase the fraction of inspired oxygen B. Collect equipment for a needle aspiration C. Replace the ventilator D. Measure the nasogastric tube output E. Place the client in Trendelenburg

Correct Answer is {"A":{"answers":"A"},"B":{"answers":"B"},"C":{"answers":"C"},"D":{"answers":"A"},"E":{"answers":"B"}}

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.
