Question
increased ventilation, what would be the 17. If the respiratory difficulties stated included prolonged periods of of this? Increased sympathetic activation of the adrenal medulla Decreased sympathetice activation of the adrenal medulla Increased activation of sympathetic post-ganglionic d. Decreased activation of parasympathetic e. A, C&D; ab. All of the above post-ganglionic neurotransmitters motor and visceral nervous system 38. Which of the following and the symptoms seen in this patient? a. Target tissues are skeletal muscle and viscera, respectively b. is NOT TRUE concerning the communication for the somatic cranial nerve muclei and in the ventral vs. lateral spinal cord, respectively are primarily ACh in the somatic system, but not always in the visceral Cell bodies are located within the c. System-wide d. Receptor sites for neurotransmitters neuronal synapses will vary from one to two, respective of the given system utilized e. All axons are myelinated A 64 year-old female is brought into the emergency score) of 6 out of 15. The paramedics have intubated (placed a tube to assi history, determine that she may be suffering a stroke. Her current vital signs are: 45; respirations- abnormal. A head CT and follow up angiogram (radiographic the patient has suffered a ruptured aneurysm with subsequent cerebral hemorrhage. She surgery and is immediately brought to the operating room department by EMS. She is unresponsive with a GCS (neurological status st breathing) the patient, and based on her past blood pressure- 164/62 mmHg: heart rate- examination of the blood vessels) reveal that is considered a good candidate for 39. Given that the patient has a blown pupil (overly dilated, unresponsive pupil), what cranial nerve would you injured? a. Optic n. b Trochlear n. c. Trigeminal n suspect to be Oculomotor n e Abducens n. 40. It is determined the patient has also lost complete motor and sensory function to the entire thigh. Based on this what dermatome(s) may have been effected by the stroke? b. Si 2 41. Researchers hypothesize that remyelination of neurons following stroke/brain injury may improve outcome. What CNS cell should a therapy target to enhance remyelination? a. Schwann cells b. Astrocytes C. Oligodendrocytes ollowing surgery, the patient becomes conscious with no cognitive deficits.However, she has decreased motor functi in her left upper extremity. We would expect to see what complications due to this issue: a. b. c. d. Decreased Ach (acetylcholine) production Decreased density of nicotinic receptors along the receptors Decreased density of beta adrenergic receptors along the receptors A&C;Explanation / Answer
