What is the most common perioperative complication in patients with long bone fractures?

• Hypotension due to anesthesia

• Fat embolism syndrome

• Venous thromboembolism

• Postoperative respiratory failure

Bone Cement Implantation Syndrome (BCIS) is characterized by the following manifestations, EXCEPT:

• Systemic hypertension

• Hypoxia

• Hypotension

• Decreased cardiac output

Which strategy for preventing BCIS is NOT recommended?

• Increase FiO₂ before cement placement

• Use cementless prosthesis if possible

• Administer high-dose heparin

• Create a vent hole in the distal femur

Patients with rheumatoid arthritis (RA) are at high risk for airway complications during intubation because of:

• Cervical spine deformities (atlantoaxial subluxation)

• Pulmonary hypertension

• Coagulation disorders

• Osteoporosis

The selection of cementless implants is more recommended for patients who are:

• Elderly >80 years with osteoporosis

• Young active adults with good bone quality

• Patients with a history of DVT

• Bone cancer patients

The physiological effects of PMMA monomer absorption on bone cement are:

• Systemic vasoconstriction

• Vasodilation & decreased systemic vascular resistance

• Increased platelet aggregation

• Intramedullary hypertension

Complications that increase after pelvic/hip surgery include:

• Fat embolism syndrome

• Venous thromboembolism

• Acute kidney failure

• Aspiration pneumonia

The local anesthetic that consistently causes vasoconstriction at all concentrations is:

• Lidocaine

• Bupivacaine

• Cocaine

• Ropivacaine

In patients with spinal osteoarthritis, the intubation maneuver that should be avoided is:

• Use of video laryngoscope

• Excessive neck manipulation

• Neutral head position

• Fiberoptic bronchoscopy

The main advantage of regional anesthesia in orthopedic surgery is:

• Reducing the risk of massive bleeding

• Accelerating rehabilitation and patient discharge

• Preventing compartment syndrome

• Decreasing transfusion requirements
