When suctioning a patient with an endotracheal tube (ETT), the nurse should limit the suctioning time to:

Choice A rationale:

Donning personal protective equipment (PPE) is the priority action before performing sterile suctioning. This helps prevent the transmission of infection from patient to nurse and vice versa.

Choice B rationale:

Preoxygenating the patient with 100% oxygen is essential before nasopharyngeal suctioning, but the priority action is to ensure the nurse's safety by using PPE.

Choice C rationale:

Obtaining baseline data on vital signs and secretions is an important step, but it can be done after the nurse has ensured their safety with appropriate PPE.

Choice D rationale:

Inserting the catheter into the artificial airway using sterile technique is part of the procedure but should be preceded by wearing proper PPE to maintain a sterile environment.

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.
