✍️ Sample CNS Questions & Answers
1. What is the main function of the central nervous system?
The central nervous system (CNS), comprising the brain and spinal cord, acts as the primary control center for the entire body. It processes sensory information, initiates voluntary movements like walking and talking, and regulates essential involuntary functions such as breathing, heart rate, and digestion. Its comprehensive role makes it responsible for coordinating nearly all bodily activities and responses.
2. What is the function of the sympathetic nervous system?
The sympathetic nervous system is a division of the autonomic nervous system primarily responsible for the 'fight or flight' response. It prepares the body to react to perceived threats or stress by increasing heart rate, dilating pupils, diverting blood flow to muscles, and releasing adrenaline. This system is crucial for survival, enabling rapid physiological adjustments to dangerous situations.
3. In status epilepticus, the initial IM midazolam dose for an adult over 40 kg without IV access is:
Per the RAMPART trial, adults over 40 kg get 10 mg IM midazolam, which works as well as IV lorazepam.
4. In the context of Certified Neuro Specialist, what is the primary goal of pharmacology basics?
The primary goal of pharmacology basics in Certified Neuro Specialist is always to achieve optimal patient outcomes while maintaining safety standards.
5. Giving opioids to relieve dyspnea in end-stage ALS, knowing they may shorten life, is justified by which principle?
