When treating a patient with an abdominal injury, which of the following should NOT be done?

Providing a drink of water to a patient with an abdominal injury is not advised because ingestion of fluids can complicate the patient's condition, especially if surgery is required later. When a patient presents with signs of an abdominal injury, there may be internal damage, which could include perforation of the digestive tract. If the patient requires surgical intervention, having food or liquid in the stomach can increase the risk of aspiration or complicate anesthesia management.

In contrast, covering the injury with a dressing is a standard practice to help protect the wound from infection and further injury. Assessing for signs of shock is crucial in any trauma situation as it helps identify if the patient is losing blood or experiencing systemic complications. Administering supplemental oxygen is also a key intervention in many trauma cases, as it can help maintain adequate oxygenation for patients who may be experiencing respiratory distress or hypoxia.
