Step by step
Solved in 3 steps
- Concerning the visual pathway, the information will be relayed to what part of the brain stem, which is also the region for the visual reflex? Question options: A medulla oblongata B pons C midbrainAt the fundus examination, you want to achieve maximum pupil enlargement. With what preparations can you do that? Below you will find five suggestions for mechanisms of action during preparation and which neurotransmitters they thereby affect. Indicate which two of these options can be used to achieve student enlargement. Note that both mechanism of action and neurotransmitters must be correct! Choose one or more alternatives: Adrenergic receptor agonist acting by mimicking the effect of acetylcholine Adrenergic receptor antagonist acting by inhibiting the effect of noradrenaline Adrenergic receptor agonist acting by mimicking the effect of norepinephrine Colinergic receptor antagonist acting by inhibiting the effect of acetylg. receptor to mimic the effect of acetylcholineWhat should be the distance between Mr. Saleto and the Snellen chart? 6ftaway What instructions can Casey give to Mr. Saleto if he uses glasses? By using the Snellen chart, is Cassey testing distance or near visual acuity? What does it mean if the result of the test is 20/60? What are some nonverbal cues that may indicate that the patient is having difficulty reading the line to which Cassey is pointing?
- Then, analyze the following hypothetical situation: Cassey Madrid is a medical assistant at a medical office. He is testing visual acuity in patients for the first time and feels nervous about it. However, Cassey remembered when he did it in his clinical procedures class, so he takes a deep breath and calls the patient, Mr. Saleto. After identifying the patient and welcoming him in the room, Cassey explains the procedure to Mr. Saleto. What should be the distance between Mr. Saleto and the Snellen chart? What instructions can Casey give to Mr. Saleto if he uses glasses? By using the Snellen chart, is Cassey testing distance or near visual acuity? What does it mean if the result of the test is 20/60? What are some nonverbal cues that may indicate that the patient is having difficulty reading the line to which Cassey is pointing?List the four visual problems and define/explain each of the terms.
