NU606 Advanced Pathophysiology

Week 9 Discussion

Team A (Sensory Disorders)

Week 9 Discussion Team A Worksheet (Word)

Sensory Disorders

Infection and trauma can happen to both the cornea and the conjunctiva. Which is more serious? Using pathophysiology, explain why.

Compare wide-angle and narrow-angle glaucoma, including the pathophysiology and signs of each.

Describe the two types of macular degeneration and current treatments.

Patients who have experienced a blow to the back of the head often report “seeing stars.” Using pathophysiology, explain why this happens.

Otitis media is much more common in infants and young children. Thinking about the structure and function of the ear, explain why this is.

Why does Ménière's syndrome cause both hearing loss and vertigo?

Team B

Week 9 Discussion Team B Worksheet (Word)

General Neurologic Dysfunction

In some neurologic disorders, postsynaptic membrane permeability is increased. Does this make the neuron more easily stimulated or less excitable? Using pathophysiology, explain why.

Cholinergic drugs are often used to help correct neurologic pathologic processes. Briefly describe where a cholinergic drug acts and how it affects the postsynaptic receptors. Give two examples of its possible effects on function.

Describe two possible areas of CNS damage that might cause flaccid paralysis. What signs and symptoms would a patient with this condition exhibit?

There are many different conditions that can cause increased intracranial pressure (ICP); identify two. What are the early signs and symptoms of increased ICP? What will you look for in a patient to help determine if they have increased ICP?

Describe how vital signs change from early increased ICP to later stages.

Which is more critical: a lesion in the brainstem or in the cerebral hemisphere? Using pathophysiology, explain why.

Team C (Neurologic Trauma/Disorders)

Week 9 Discussion Team C Worksheet (Word)

Neurologic Trauma/Disorders

What is a subdural hematoma? In your definition, be sure to include location, common causes, and time to development. What signs and symptoms would you expect a patient with a subdural hematoma to exhibit?

Spinal cord injury can occur anywhere along the spine. Is injury to the cervical spine or lumbar spine more critical? Using pathophysiology, explain why.

What is the difference between communicating and noncommunicating hydrocephalus? This can occur in infants, often with no focal signs. Explain why this is.

What is the difference between a partial and a general seizure? Give an example of each, and describe what you might expect to observe from a patient experiencing each type.

Describe where you might expect to find plaques that cause the following early signs of multiple sclerosis: diplopia, tremors in the legs, facial weakness.

Describe three common manifestations that can be observed in a person with Parkinson's disease. Why might these make it difficult for patients to maintain adequate nutrition and hydration? What potential complications may ensue?
