Orthopaedic Technologist Flashcards

Which of the following details is most crucial for determining a patient's degree of interest?

Answer: type of activity, past interest, recent past interest, current participation, and future interest in participation

To accurately determine a patient's degree of interest, a comprehensive assessment is required that goes beyond just the type of activity. It involves understanding their historical engagement (past and recent past interest), their current involvement (current participation), and their future aspirations (future interest in participation). This holistic view provides a more accurate measure of their personal investment and motivation, which is crucial for effective care planning.

The youngster continues to play a video game on an electronic table while the orthopaedic technologist is interviewing him. What should the orthopaedic technologist do first?

Answer: asking the boy what kinds of apps he likes

When interviewing a child who is distracted, the most effective initial approach is to build rapport and engage them on their level. Asking about their video game or apps shows genuine interest in their world, helps establish a connection, and can make them feel more comfortable and willing to participate in the interview. This empathetic approach is more likely to yield cooperation than immediately demanding they stop their activity or remaining silent.

For treatment of a left humerus fracture, a patient will receive side arm skin traction. In what areas are traction tapes used?

Answer: to the upper arm, extending past the elbow, and to the forearm, extending beyond the hand

For side arm skin traction, the traction tapes must be applied to both the upper arm and the forearm to effectively distribute the pulling force and stabilize the humerus fracture. Extending the tapes past the elbow on the upper arm and beyond the hand on the forearm ensures maximum surface area for adhesion. This broad application helps to maintain proper alignment, prevents skin irritation, and provides optimal traction mechanics for the fracture.

What temperature should the water be while casting with extra-quick-setting plaster?

Answer: cold

The setting time of plaster of Paris is directly influenced by water temperature. Extra-quick-setting plaster is designed to set very rapidly, so using cold water helps to slow down the chemical reaction. This provides the orthopaedic technologist with a slightly longer and more manageable working time to mold and apply the cast accurately before it hardens completely, ensuring proper fit and alignment.

A baby with a clubfoot is wearing progressive plaster casts, and the present cast needs to be taken off. What is the most effective way to remove the cast?

Answer: soak the cast in a warm water with 1 tbsp of vinegar for 1 hour

For a baby's progressive plaster cast, soaking it in warm water with vinegar is a gentle and safe method for removal. The vinegar helps to dissolve the plaster, making it soft and pliable, which allows for easy and atraumatic removal without the need for a cast cutter. A longer soaking time, such as one hour, ensures the cast is thoroughly softened, minimizing discomfort and potential skin irritation for the infant.

A patient in pelvic skin traction is given permission to use the restroom and requests assistance from the orthopaedic teacher to stand up. Should the orthopaedic technologist?

Answer: remove the weights and then the pelvic belt

When a patient in pelvic skin traction needs to stand, the traction force must first be released to prevent injury. This is achieved by carefully removing the weights that apply the traction. Once the weights are removed, the pelvic belt, which is directly applying the traction, can then be safely removed to allow the patient full mobility to stand up without resistance or risk of sudden jarring.

Which imaging method from the list below is best for identifying osteomyelitis brought on by an infected traumatic injury?

Answer: Magnetic resonance imaging (MRI)

Magnetic Resonance Imaging (MRI) is considered the most sensitive and specific imaging modality for diagnosing osteomyelitis, especially when caused by an infected traumatic injury. MRI provides excellent soft tissue contrast, allowing for early detection of bone marrow edema, abscess formation, and soft tissue involvement, which are characteristic signs of infection. Other methods like standard radiographs are often normal in early stages, and CT scans are less sensitive for marrow changes.
