Reference answer and analysis
1. Reference answer A. Analysis: This question examines the treatment of neuropathic pain. Pregabalin is a new calcium channel regulator, which can block voltage-dependent calcium channels and reduce the release of neurotransmitters. Clinically, it is mainly used to treat peripheral neuralgia. Carbamazepine is an antiepileptic drug and a long-term preventive drug for trigeminal neuralgia and glossopharyngeal neuralgia. Parecoxib is a specific inhibitor of cyclooxygenase -2(COX-2). Which belongs to the anti-arthritis drugs. Duloxetine is used to treat depression and generalized anxiety disorder.
2. Reference answer B. Analysis: This question examines the clinical manifestations of peripheral vascular diseases. Arteriosclerosis obliterans is a common disease in the arterial system of the elderly. Its pathological process is slow and hidden, and its clinical manifestations are ischemic limb pain, intermittent claudication and weakening or disappearance of arterial pulse.
3. Reference answer A. Analysis: This question examines the diagnosis of Raynaud's disease. Patients with Raynaud's disease often turn pale and then purple after a cold or emotional excitement. The attack often begins at the fingertips and then spreads to the whole finger or even the palm. Accompanied by local chills, numbness, tingling and hypoesthesia. The patient can be diagnosed as Raynaud's disease according to his medical history.
4. Reference answer B. Analysis: This question examines the diagnosis of cervical spondylosis. According to the symptoms and signs, especially the positive results of skull test and brachial plexus traction test, it is suspected that it is the diagnosis of cervical spondylosis, and MRI should be chosen for further examination. Cervical MRI has more advantages than other examinations in degenerative changes such as cervical intervertebral disc and ligament.
5. Reference answer D. Analysis: This question examines the indications of lumbar sympathetic nerve block. The details are as follows: Vascular diseases of lower limbs and their accompanying pain, trauma and postoperative pain of lower limbs can also be used to predict the therapeutic effect of lumbar sympathectomy. So choose D.
6. Reference answer D. Analysis: This question examines the concept and memory topic of the intensive care unit. Intensive care unit (ICU) refers to a place equipped with professional medical staff and adopting advanced medical monitoring and treatment methods to implement centralized management of critically ill patients.
