Which condition or changes indicate to the nurse that a patient with a tracheostomy requires suctioning? Select all that apply.

Crackles and wheezing indicate the presence of excessive mucus or secretions in the airways, which may require suctioning to clear the airway and improve breathing. The presence of serosanguineous drainage on the tracheostomy dressing may indicate increased mucus production or bleeding, suggesting the need for suctioning to remove secretions or assess for any bleeding complications. Regular suctioning is necessary to maintain a patent airway for patients with a tracheostomy. If suctioning was performed more than 4 hours ago, it may be time for another suctioning session to prevent the accumulation of secretions and maintain airway clearance. While a fever may indicate an underlying infection or inflammation, it does not specifically indicate the need for suctioning. The decision to suction should be based on the patient's respiratory assessment and the presence of respiratory symptoms. While patient requests and preferences are important, the need for suctioning should be determined based on clinical indicators and assessment findings rather than solely relying on patient requests.
