Understanding Upper Extremity Injuries

What is the primary function of the rotator cuff in the shoulder?

• To stabilize the shoulder joint

• To flex the elbow

• To extend the wrist

• To rotate the forearm

Explain how a dislocated shoulder can impact the range of motion and what steps should be taken to address it.

• It causes increased range of motion; rest and ice are sufficient.

• It limits range of motion; immediate reduction and rehabilitation are necessary.

• It has no impact on range of motion; no treatment is needed.

• It causes pain but no range of motion issues; painkillers are enough.

Which bone is commonly fractured in a wrist injury?

• Humerus

• Scaphoid

• Femur

• Tibia

Describe the strategic approach to diagnosing a suspected elbow fracture.

• Perform a visual inspection only.

• Use an X-ray to confirm the fracture and assess the extent of injury.

• Apply a cast immediately without further assessment.

• Wait for swelling to subside before any diagnosis.

What is the anatomical term for the shoulder blade?

• Clavicle

• Scapula

• Sternum

• Radius

Plan a rehabilitation strategy for a patient recovering from a rotator cuff tear.

• Immediate return to full activity

• Gradual strengthening exercises and physical therapy

• Complete immobilization for six months

• Use of pain medication only

Which muscle is primarily responsible for elbow flexion?

• Triceps brachii

• Biceps brachii

• Deltoid

• Pectoralis major

Evaluate the potential complications of an untreated wrist fracture.

• No complications; it heals on its own.

• Possible chronic pain and reduced mobility.

• Improved wrist strength.

• Enhanced flexibility.

What is the function of the ulna in the forearm?

• To support the shoulder joint

• To provide structure and support to the forearm

• To connect the wrist to the fingers

• To protect the heart

Strategize a treatment plan for a patient with a severe shoulder dislocation.

• Immediate surgery without any imaging

• Reduction under anesthesia followed by physical therapy

• Ignore the dislocation and continue normal activities

• Use of a sling indefinitely
