A nurse is assisting with planning in-service training for staff members about manifestations of opioid use. Which of the following manifestations should the nurse include when discussing opioid intoxication? (Select all that apply.)

Prevention of musculoskeletal or stress injuries focuses on maintaining proper body mechanics during activities such as lifting, pulling, and moving objects. Safe body alignment reduces strain on muscles, joints, and ligaments and helps prevent acute and chronic injuries. Key principles include keeping the center of gravity stable, using large muscle groups, and avoiding twisting movements. Proper education helps clients perform daily activities safely and reduce occupational or activity-related injuries.

Rationale:
A. “I will position my arms away from my body when pushing an object.” This reflects incorrect body mechanics. Keeping objects or actions close to the body is important because it reduces leverage strain on muscles and joints. Extending the arms increases the load on the back and shoulders, increasing the risk of injury rather than preventing it.

B. “I will position objects away from my body before lifting them.” This is incorrect because lifting objects farther from the body increases strain on the lower back. Proper technique requires keeping objects close to the center of gravity to maintain stability and reduce spinal stress. This statement demonstrates misunderstanding of safe lifting principles.

C. “I will position my legs close together before lifting.” This is incorrect because a narrow base of support reduces balance and stability. Proper body mechanics require feet to be shoulder-width apart to provide a stable base and distribute weight evenly. Keeping legs close together increases the risk of falls and musculoskeletal strain during lifting activities.

D. “I will position my body to face an object, so I avoid twisting.” This demonstrates correct understanding of body mechanics principles. Twisting the spine while lifting or moving objects places excessive stress on vertebral structures and increases injury risk. Facing the object directly and using the legs for lifting helps maintain spinal alignment and protects musculoskeletal integrity.

A long leg cast is used to immobilize fractures and promote bone healing, but it can also lead to complications such as compartment syndrome, impaired circulation, and nerve compression. After cast application, ongoing assessment of neurovascular status is essential to detect early signs of compromised perfusion. Pain that worsens rather than improves is a critical warning sign of potential complications requiring immediate intervention. Nurses must differentiate expected discomfort from abnormal findings that indicate tissue ischemia.

Rationale:
A. Increasing pain in the affected extremity is a hallmark early sign of compartment syndrome or impaired circulation under the cast. This type of pain is often severe, unrelieved by analgesics, and may worsen with movement. It indicates rising pressure within the muscle compartments that can compromise blood flow and tissue viability, requiring immediate provider notification.

B. Itching beneath the cast is a common and expected finding during the healing process. It results from skin dryness and tissue regeneration under immobilization. Although uncomfortable, it does not indicate neurovascular compromise and can be managed with safe comfort measures.

C. Warm toes indicate adequate peripheral perfusion and are a normal finding after cast application. This suggests that arterial blood flow to the distal extremity is intact. It is a reassuring sign rather than an abnormal one that requires reporting.

D. Capillary refill of 3 seconds is slightly delayed but may still be within acceptable limits depending on baseline and clinical context. However, it is less urgent than escalating pain. It should be monitored closely, but increasing pain is a more critical early indicator of compromised circulation that requires immediate attention.
