A nurse is caring for a client who has a C4 spinal cord injury. Which of the following should the nurse recognize the client as being at the greatest risk for?

Choice A reason: Respiratory compromise is the greatest risk for a client with a C4 spinal cord injury. The C4 spinal level is critical for the function of the diaphragm, which is the main muscle responsible for breathing. Injury at this level can impair diaphragmatic function, leading to difficulty in breathing or even respiratory failure. Immediate and continuous monitoring of respiratory status is essential for these patients to ensure adequate ventilation and oxygenation.Choice B reason: Stress ulcers can develop in patients with spinal cord injuries due to the stress response and immobility. However, they are not the highest immediate risk compared to respiratory compromise, which can be life-threatening if not promptly addressed.Choice C reason: Paralytic ileus, a condition where the intestines stop moving, can occur in spinal cord injury patients due to disruption of the nervous system control of the gut. While it is a significant concern, it is not as immediately life-threatening as respiratory compromise.Choice D reason: Spinal shock is a condition that can occur after a spinal cord injury, leading to temporary loss of reflexes below the level of the injury. While it is an important condition to recognize and manage, the most urgent risk for a patient with a C4 injury is respiratory compromise due to the potential impact on breathing.
