- Choose the correct answer to fill in the blanks: The dorsal roots carry (sensory, motor, or both) information (into, away, or both) the spinal cord. Damage to a dorsal roof is most likely to cause (parenthesis, or paralysis) in the affected area. The ventral roots carry (sensory, motor, or both) information (into, away, or both) the spinal cord. Damage to a ventral roof is most likely to cause (paresthesias or paralysis) in the affected area.arrow_forwardWhen you touch a hot stove, action potentials are SENT to which part of the spinal cord?

- A patient is brought into the emergency room showing symptoms such as dropping mouth and slurred speech. The doctor suspects a stroke and immediately arranges a computerized tomography (CT) scan of the patient's head to aid diagnostics. Discuss why the doctor may have suggested a CT scan over magnetic resonance imaging (MRI). Describe in detail the physical basis of CT. The next day after the patient has been hospitalized the doctor decides to have a MRI to complement the diagnosis. Name one advantage of MRI compared to CT. Describe in detail the physical basis of MRI. The are two main types of stroke: ischemic, caused by a lack of blood flow and hemorrhagic, due to bleeding. On the basis of the CT scan, discuss how each type of stroke would appear in the CT scan. Since the patient has hypercholesterolemia and reported pain in the left arm during hospitalisation, the doctor wants to clarify if the patient may suffer from atherosclerosis in the carotid artery.

- John accompanied his wife Stacy to the clinic today seeking a walk-in appointment. He explains that STacy slipped and fell on some ice while walking to her car last night. John informs you that aside from a some cuts and bruises on her body, her "arm socket" is really hurting her. He states that "she may need an X-ray" and some "drugs" to help her with the pain. You notice that Stacy is consistently looking away from you as her husband talks. She seems very tense and axious. You make the decision, after looking at the schedule, that stacy can be seen in about 20 minutes. You inform John and Stacy and ask them to take a seat in the waiting room. You are going to perform necessary triage and vital signs on Stacy and call her name in the waiting room. John immediately stands up tp escort Stacy. You inform John that there is limited space in the triage area for him to accompany Stacy and will bring stacy back to the waiting room after you obtain vitals and gather other basic information.…arrow_forwardNurse Marina is conducting Maternal and Child Lecture series to College of Nursing students.
