A nurse is caring for a client receiving mechanical ventilation. The nurse should prioritize which action associated with neuromuscular blockade use?

Pulmonary Function Tests assess chronic respiratory conditions like COPD and asthma. In an acute pneumothorax, these tests are unnecessary as the priority is stabilizing the airway and restoring lung expansion. The client is in respiratory distress, making PFTs impractical and irrelevant at this stage.

Obtain Intravenous Access: IV access is necessary to administer fluids, medications, and potential emergency interventions. Given the client's signs of respiratory distress and hemodynamic instability (tachycardia, hypotension), IV access ensures rapid treatment in case of deterioration.

Thoracentesis: Thoracentesis is used to remove pleural fluid in conditions like pleural effusion but is not appropriate for a pneumothorax. Inserting a needle into the pleural space could worsen the lung collapse and lead to further respiratory compromise. The correct intervention is a chest tube insertion.

Obtain ABGs: ABGs provide critical information on oxygenation, ventilation, and acid-base balance. The client has tachypnea, cyanosis, and low O₂ saturation, indicating possible respiratory acidosis or hypoxemia. ABGs will guide oxygen therapy and further management.

Prepare for Insertion of a Chest Tube: A chest tube is the definitive treatment for a pneumothorax. It removes air from the pleural space, allowing lung re-expansion. Given the client's absent breath sounds, tachypnea, and hypoxia, immediate chest tube insertion is necessary to prevent further deterioration.

Computed Tomography (CT) of the Chest: While a CT scan provides detailed lung imaging, it is not the first-line diagnostic tool for pneumothorax. A chest X-ray is usually sufficient to confirm the diagnosis. In an emergency setting, immediate intervention (such as chest tube placement) takes priority over advanced imaging.

• Clostridium difficile infection is likely because the client has pneumonia and is receiving ceftriaxone, an antibiotic known to disrupt gut flora and cause opportunistic infections like C. difficile. The presence of frequent, liquid, foul-smelling stools further supports this diagnosis.
• Myocardial infarction is unlikely because while the client has chest pain, it is pleuritic and related to inspiration rather than the typical crushing, non-pleuritic chest pain seen in an MI. There is no mention of radiating pain, diaphoresis, or hemodynamic instability.
• Pulmonary edema is unlikely since it typically presents with dyspnea, crackles throughout the lung fields, pink frothy sputum, and signs of fluid overload such as peripheral edema and weight gain. The client’s symptoms do not align with this condition.
• Pulmonary embolism is also unlikely, as it presents with sudden-onset dyspnea, pleuritic chest pain, tachycardia, and often calf swelling or a history of deep vein thrombosis. The client lacks the risk factors and clinical signs of PE.
• Placing the client on contact precautions is necessary because C. difficile is highly contagious and spreads through the fecal-oral route. Gloves and gowns should be used to prevent transmission.
• Obtaining a stool culture is necessary to confirm the presence of C. difficile toxins in the stool, which is essential for accurate diagnosis and treatment.
• Requesting a prescription for an anticoagulant is not necessary because the client does not show any signs of thromboembolic disease such as deep vein thrombosis or pulmonary embolism. Anticoagulation could increase the risk of bleeding in the gastrointestinal tract, which would worsen the diarrhea.
• Requesting a prescription for a diuretic is not needed because the client is more likely to be dehydrated due to diarrhea. Diuretics would exacerbate fluid loss and electrolyte imbalances.
• Restricting fluids is not appropriate because dehydration is a major concern with C. difficile infection. Instead, fluid intake should be encouraged to prevent complications from excessive fluid loss.
• Level of consciousness should be monitored because severe dehydration and electrolyte imbalances can lead to confusion, weakness, and altered mental status. While altered mental status can occur with severe dehydration or sepsis, it is not the primary concern at this stage.
• Potassium level should be monitored because diarrhea can cause significant potassium loss, leading to hypokalemia, which can result in muscle weakness, cardiac arrhythmias, and fatigue.
• Urine output is not the most specific parameter for monitoring C. difficile infection. While dehydration is a concern, tracking electrolyte levels and neurological status is more critical.
• Calf swelling is not relevant since the client does not have signs or risk factors for deep vein thrombosis or pulmonary embolism.
• Weight: C. difficile infection can cause significant fluid loss due to persistent diarrhea, leading to dehydration and weight loss. Tracking daily weight helps assess hydration status and the effectiveness of fluid replacement therapy.
