During endotracheal suctioning, which step should be performed first?

• A. Assess crackles and mucous in the trachea.
• B. Wash hands and don protective eyewear.
• C. Hyperoxygenate until oxygen saturation is between 95 to 100%.
• D. Open sterile tray while maintaining sterility.

Answer: (B)

In the context of endotracheal suctioning, the first step should involve ensuring proper infection control and safety protocols. Therefore, washing hands and donning protective eyewear is essential to prevent cross-contamination and protect both the healthcare provider and the patient from exposure to infectious material. This step lays the groundwork for a safe and sterile environment, which is crucial before proceeding with any clinical procedure.

After ensuring proper hygiene and applying protective equipment, additional steps such as assessing the patient's lung sounds or hyperoxygenating can be effectively performed. Maintaining sterility by opening a sterile tray is also important, but it cannot take precedence over establishing a safe operational environment. Thus, adhering to this sequence ensures that the suctioning process can be carried out safely and effectively.
