An emergency department client is diagnosed with a hip dislocation. The client's family is relieved that the client has not suffered a hip fracture, but the nurse explains that this is still considered to be a medical emergency. What is the rationale for the nurse's statement?

A. Malunion: Malunion happens when a fractured bone heals in an improper position, leading to deformity and functional impairment. While it is a concern, it typically develops over time during the healing process and is not an immediate early complication that the nurse would monitor for in the acute phase following a fracture.

B. Compartment syndrome: Compartment syndrome is a serious condition that can occur after an injury, such as a fracture. When there is increased pressure within a muscle compartment, it can lead to reduced blood flow, potentially causing tissue damage and nerve injury. Prompt recognition and intervention are crucial to prevent complications.

C. Fat embolism: Fat embolism occurs when fat particles from the bone marrow or other sources enter the bloodstream, often after a long bone fracture or major trauma. These particles can travel to the lungs and other organs, causing respiratory distress, confusion, and other symptoms. Fat embolism is a significant concern in orthopedic trauma patients and requires careful monitoring.

D. Deep vein thrombosis (DVT): DVT is the formation of blood clots in deep veins, usually in the legs. Patients with fractures, especially those immobilized for extended periods, are at increased risk for DVT. If a clot dislodges and travels to the lungs, it can cause a pulmonary embolism, which is a life-threatening complication.

E. Pulmonary emboli: Pulmonary emboli occur when blood clots, often originating from DVT, travel to the lungs and block pulmonary arteries. This condition can lead to sudden difficulty breathing, chest pain, and even cardiac arrest. Pulmonary embolism is a medical emergency and requires immediate intervention.

A. Increase sodium intake - This is not a preventive measure for osteoporosis. High sodium intake can lead to increased calcium excretion and weaken bones.

B. Drink a cup of coffee each morning - Caffeine consumption, especially in excess, can interfere with calcium absorption and increase calcium excretion. Limiting caffeine intake is recommended for bone health. Drinking coffee in moderation is acceptable but excessive consumption should be avoided.

C. Have a bone-density scan each year - While bone-density scans (DEXA scans) are useful for diagnosing osteoporosis or assessing bone health, they are not typically recommended for young adults with a family history of osteoporosis unless there are specific risk factors present. Yearly scans are unnecessary and not cost-effective for young adults without significant risk factors.

D. Engage in weight-bearing exercise regularly - Weight-bearing exercises, such as walking, jogging, dancing, and resistance training, help to increase bone density and strength. Regular physical activity, especially weight-bearing exercises, is a recommended preventive measure against osteoporosis.
