Which of the following factors can lead to complications during suctioning?

Excessive suction time can lead to complications during suctioning because prolonged suctioning can irritate the airway, cause trauma to the tissues, and lead to a decrease in oxygen levels in the patient. It’s essential to limit suctioning to prevent these adverse effects.

Improper insertion technique is another critical factor that can lead to complications. If the catheter is inserted too deeply or incorrectly, it can cause damage to the airway or induce a gag reflex, which could lead to airway obstruction or distress for the patient.

Unnecessary suctioning is also problematic as it can cause additional trauma and irritation to the airway, potentially leading to complications such as increased mucus production, edema, or even hypoxia.

Choosing "All of the above" as the answer appropriately recognizes that each of these factors—excessive suction time, improper insertion technique, and unnecessary suctioning—can contribute to complications during suctioning, highlighting the importance of adhering to proper suctioning protocols to ensure patient safety.
