Celecoxib is what class of drug?
Corticosteroid
Muscle relaxant
Narcotic
Nonsteroidal anti-inflammatory drug (NSAID)
The Correct Answer is D
Nonsteroidal anti-inflammatory drugs (NSAIDs) are a class of medications commonly used to relieve pain, reduce inflammation, and lower fever. They work by inhibiting the production of prostaglandins, which are substances in the body that play a role in pain and inflammation. Celecoxib specifically belongs to the subclass of NSAIDs known as selective COX-2 inhibitors, which target the enzyme cyclooxygenase-2 (COX-2). By selectively inhibiting COX-2, celecoxib helps to reduce inflammation and pain while potentially minimizing the gastrointestinal side effects associated with traditional non-selective NSAIDs.

Correct Answer is C
Explanation
A low-pressure ventilator alarm indicates a potential issue with the delivery of adequate air or pressure from the ventilator. The pulse oximetry reading of 85% suggests that the client is not receiving sufficient oxygenation.
Providing ventilation with a bag-valve-mask device allows the nurse to manually assist the client's breathing and ensure proper oxygenation and ventilation while troubleshooting the ventilator alarm. By manually ventilating the client, the nurse can help maintain oxygenation and prevent further hypoxemia until the underlying cause of the alarm can be identified and resolved.
Suctioning the client's endotracheal tube, adding air to the pilot balloon, or placing a bit block in the client's mouth may be appropriate interventions in specific situations, but they are not the immediate priority in this case. The primary concern is to address the low oxygen saturation and ensure adequate ventilation.
Correct Answer is ["C","D","E"]
Explanation
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.
