Outpatient Office Encounter
The patient, Mrs. Elaine Markus, is a 37-year-old woman with a history of migraine headaches and visual field disturbances.
History of Present Illness
✓ Expand All
A Collapse All
Mrs. Elaine Markus is a 37-year-old woman with a history of migraine headaches and visual field disturbances. She has a left medial lower quadrant
defect lan area of reduced visual function) that was noted in December of 2014 and has been stable. She recently developed a right temporal lower
quadrant defect, which was first noted in September of 2019 and has had worsening symptoms in October.
Prior Imaging
An MRI in November showed a normal study of the brain including visual cortex and periventricular white matter, with a normal
study of the orbits, optic nerves, and extra ocular muscles. A pituitary microadenoma (small benign tumor of the pituitary gland) of
approximately 3 mm on the left side of the gland was found with…

4. Write a brief report using the following terms related to disorders
of the middle ear: otitis media, serous otitis media, acute purulent
otitis media, and chronic otitis media.
Group Assignment
1. Divide into two groups: group A and group B. The students in
group A should develop a list of potential client problems
associated with a visual deficit, and the students in group B should
prepare a similar list but addressing a hearing deficit. Within your
group, develop appropriate nursing interventions for each of the
problems you identify. Present the information to the rest of the
class and engage in a discussion with the other group of the
similarities or differences of problems and interventions.
