- 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.

Correct Answer is D
Explanation
A. Administer furosemide IV over ten minutes. While slow IV administration is recommended to prevent ototoxicity, the priority concern is that milrinone and furosemide are incompatible when administered in the same IV line. The nurse must first ensure separate IV access before considering the administration rate.
B. Notify the healthcare provider (HCP) of the incompatibility of the two drugs. The nurse does not need to notify the HCP but should instead use a separate IV line or flush the line thoroughly before and after administration if only one access is available. Milrinone and furosemide should never be mixed, as their combination can cause precipitation, leading to catheter occlusion or embolization.
C. Infuse furosemide through a central line to prevent extravasation. Furosemide can be given peripherally or centrally, but the concern here is drug incompatibility, not extravasation. Furosemide is not a vesicant, so central line administration is not required unless no peripheral access is available.
D. Give furosemide through a separate IV access. Milrinone is incompatible with furosemide due to pH differences, which can lead to precipitation and potential catheter occlusion. To ensure safe administration, furosemide should be given through a separate IV line or, if no secondary access is available, the line should be flushed thoroughly before and after administration.
Correct Answer is C
Explanation
A. Suture removal kit. A suture removal kit is used when the chest tube is ready for removal, but it is not necessary to keep at the bedside during routine chest tube management. The priority is ensuring emergency supplies are available if the tube becomes dislodged.
B. Suction catheter. A suction catheter is used to remove secretions from the airway but is not essential for managing a chest tube. Chest drainage systems function independently to remove air or fluid, and routine suctioning is not required for chest tube management.
C. Sterile gauze dressing. If the chest tube accidentally dislodges, an occlusive dressing (such as sterile gauze with petroleum jelly) should be applied immediately to prevent air from re-entering the pleural space, which could lead to a tension pneumothorax. Keeping sterile gauze at the bedside ensures rapid intervention in case of accidental chest tube removal.
D. Sterile piston syringe. A sterile piston syringe is used for irrigating wounds or suctioning secretions, but it is not necessary for chest tube management. The closed drainage system should never be manually flushed unless specifically ordered by a healthcare provider.
