Texas Certified Nursing Assistant (CNA) Practice Exam

When a resident is in shock, elevating the legs is a crucial intervention. This position helps to improve blood flow to vital organs by facilitating venous return to the heart, which can help stabilize the resident's condition. Proper circulation is critically important in shock because the body's organs and tissues need adequate blood flow and oxygen to function properly. By elevating the legs, a nursing assistant can assist in addressing some of the immediate effects of shock and support the body's efforts to restore normal blood circulation.

Choosing to keep the resident sitting up can impede blood circulation and may worsen their condition. Covering the resident with a warm blanket may not be appropriate as determining the cause of shock is essential; excessive warmth might not be suitable for all types of shock. Providing sips of water is inappropriate since a person in shock may have reduced consciousness or difficulty swallowing, making the risk for choking significant. Safe, effective care in emergency situations like shock requires understanding the right actions to take, emphasizing the importance of elevating the legs.
