A nurse is caring for a number of clients. Based on the site of injury, which client is at the most immediate risk for hypoxia-induced cell injury?
A) A client admitted with an injury to the right great toe.
B) A client admitted with a chest wall injury.
C) A client admitted with a traumatic brain injury.
D) A client admitted for a right femoral head fracture.
C) A client admitted with a traumatic brain injury.
Explanation: A) Brain tissue has a survival time of less than three minutes during hypoxia. Based on the location of the injury, the client admitted for a traumatic brain injury is at the most immediate risk for hypoxia-induced cell injury. Skeletal muscle, such as that involved with the clients with injuries to the chest wall, right great toe, and right femoral head respectively, has a survival time of 60 to 90 minutes during hypoxia. Vascular smooth muscle, such as that involved with the clients with injuries to the chest wall, right great toe, and right femoral head respectively, has a survival time of 24 to 72 hours.
B) Brain tissue has a survival time of less than three minutes during hypoxia. Based on the location of the injury, the client admitted for a traumatic brain injury is at the most immediate risk for hypoxia-induced cell injury. Skeletal muscle, such as that involved with the clients with injuries to the chest wall, right great toe, and right femoral head respectively, has a survival time of 60 to 90 minutes during hypoxia. Vascular smooth muscle, such as that involved with the clients with injuries to the chest wall, right great toe, and right femoral head respectively, has a survival time of 24 to 72 hours.
