C. Chest trauma is a common cause of hyperkalemia
D. Chest trauma always results in respiratory distress

**Core Concept:** Chest trauma is a broad term that includes injuries to the chest wall, thoracic organs, and the respiratory and cardiovascular systems. These injuries can have various clinical presentations and can lead to complications like hemothorax, pneumothorax, pulmonary contusion, and rib fractures.

**Why the Correct Answer is Right:** Chest trauma can occur in different scenarios, not just motor vehicle accidents. For example, it can result from falls, sports injuries, assaults, or industrial accidents. Chest trauma does not always lead to severe chest pain as pain perception can vary among individuals.

**Why Each Wrong Option is Incorrect:**

A. False: Chest trauma can occur in various settings and not solely in motor vehicle accidents.
B. False: Chest trauma patients can present with varying degrees of pain, not exclusively severe chest pain.
C. False: Chest trauma does not universally cause hyperkalemia. Hyperkalemia can result from several other causes, not just chest trauma.
D. False: Chest trauma can present with or without respiratory distress, depending on the severity and specific injury sustained.

**Clinical Pearl:** Chest trauma can present with a wide range of symptoms and complications, making a thorough history and physical examination essential in diagnosing and managing these patients. Collaborating with other specialties, such as trauma surgery and critical care, is crucial for optimal patient care.

**Correct Answer:** C. Chest trauma does not universally cause hyperkalemia. Hyperkalemia can result from various causes, such as renal failure, adrenal crisis, or the use of certain medications. Chest trauma-induced hyperkalemia is a rare occurrence, making option C the correct answer.
