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.
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 ["5"]
Explanation
Calculation:
Calculate the New Nitroglycerin Dose in mcg/hour
Dose (mcg/hour) = Dose (mcg/min) × 60 min/hour
=15 mcg/min × 60 min/hour = 900 mcg/hour
Convert mcg to mg
Dose (mg/hour) = Dose (mcg/hour) / 1000 mcg/mg
=900 mcg/hour / 1000 mcg/mg
= 0.9 mg/hour
Calculate the Concentration of Nitroglycerin in the IV Bag
Concentration (mg/mL) = Total mg of Nitroglycerin / Total mL of Solution
=50 mg / 250 mL
= 0.2 mg/mL
Calculate the Infusion Rate = Infusion Rate (mL/hour)
=0.9 mg/hour / 0.2 mg/mL
= 4.5 mL/hour
Round to the Nearest Whole Number
4.5 mL/hour rounded to 5 mL/hour
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.
