In a dog that becomes apneic after administration of a sedative, what is the immediate course of action?

• A. Administer reversal agent
• B. Observe and monitor
• C. Apply oxygen by mask
• D. Intubate and ventilate

Answer: (D)

When a sedative leads to apnea, the top priority is to secure the airway and restore ventilation. Without breaths, oxygen delivery and carbon dioxide removal drop quickly, risking hypoxia. A reversal agent might help later, but it may take time to take effect and won’t immediately restore ventilation. Merely observing won’t address the dangerous lack of air. Providing oxygen by mask helps only if there are breaths happening; in apnea there are none. By intubating and ventilating, you establish a stable airway and deliver controlled breaths, re‑establishing both oxygenation and ventilation right away. Once the patient is ventilating, you can reassess and consider reversal or other supportive measures as needed.
