Final answer:
When possible, suction should be limited to 15 seconds to avoid complications.
Step-by-step explanation:
When possible, suction should be limited to 15 seconds. Suction is a technique commonly used in medical settings to remove fluids or secretions from a patient's airway or other body cavities. While suctioning for longer periods of time may be necessary in certain situations, prolonged or excessive suctioning can lead to complications such as tissue damage or mucosal trauma.
