A nurse is teaching infection control principles for sterile suctioning. Which measure is the most important to prevent cross-contamination during the procedure?

Choice A rationale:

The nurse should not insert the catheter until resistance is met during nasopharyngeal suctioning. This action could cause trauma to the nasal mucosa or other structures in the nasopharynx.

Choice B rationale:

Preoxygenating the patient with 100% oxygen is important before nasopharyngeal suctioning to prevent hypoxia during the procedure. Suctioning can temporarily decrease oxygen levels, so preoxygenation helps maintain adequate oxygenation.

Choice C rationale:

Applying intermittent suction while inserting the catheter is not recommended during nasopharyngeal suctioning. Continuous suction is preferred for effective removal of secretions.

Choice D rationale:

Limiting each suction pass to no more than 15 seconds is an essential practice during nasopharyngeal suctioning. Prolonged suctioning can cause hypoxia and discomfort for the patient.

Choice E rationale:

Rinsing the catheter and tubing with saline after each suction pass helps maintain patency and prevent the accumulation of secretions, ensuring effective suctioning during the procedure.

Choice A:

Plastic,.

Choice B:

Metal,.

Choice C:

Silicone, and Choice D:

Rubber.

Choice A rationale:

Plastic suctioning catheters are commonly used for sterile suctioning as they are disposable and come in various sizes for different patient needs.

Choice B rationale:

Metal suctioning catheters are also used for sterile suctioning and are often reusable, making them cost-effective for healthcare facilities.

Choice C rationale:

Silicone suctioning catheters are commonly used in sensitive situations or patients with latex allergies, as silicone is a non-allergenic material.

Choice D rationale:

Rubber suctioning catheters were commonly used in the past, but they are less common now due to the availability of more suitable materials like plastic and silicone.

Choice E rationale:

Glass suctioning catheters are not used for sterile suctioning due to the risk of breakage, which can lead to serious injuries and complications.
