Q

How can you tell the difference between Bell’s Palsy (lesion affecting the brain stem) and a stroke (lesion affecting the brain)?

A

In Bell’s Palsy the patient will have a drooped eyebrow, inability to close their eye, flat nasolabial fold, and paralysis of the lower face

In a stroke the other hemisphere can make up for some of the deficits so the patient will be able to close their eyes with some weakness, be able to raise their eyebrows, but have a flat nasolabial fold

Through basic observation and conversation

139

Eye (cornea) is not perfectly spherical; more egg or football shaped Never gives a sharp focus

Q

If you see this, what disease/condition should you be concerned about?

A

Hypertensive retinopathy

141
Q

What is the basis of Erikson’s psychosocial development?

Major themes in each phase have to be successfully negotiated. Outcome of prior phases influences how a person masters the next level Ex: Intimacy vs. isolation in adulthood

142

For tumor, infection, stroke, demyelinating disease, seizure

143
Q

If you see this, what disease/condition should you be concerned about?

A

Optic disc swelling

144

A

Convex/convergent lens

145
Q

What is Marcia’s theory of identity development?

A

The balance between exploration and commitment in exploring roles and identity in adolescence

146
Q

If you see this, what disease/condition should you be concerned about?

A

Subluxed cataract - Marfan’s syndrome

147

What is noncontrast CT good for catching?

A

Hemorrhage and fractures

148
Q

What kind of diseases affect sensation?

A

Stroke, peripheral neuropathy, compression neuropathy, radiculopathy

149
Q

How close do you need to be to a patient’s eye with the direct ophthalmoscope to properly visualize the structures?

150
Q

What is presbyopia?

A

The loss of accommodation (usually gone by age 65) With age, the lens loses the ability to change shape. The ciliary muscle contracts more and we experience eye pain/strain when things are up close

151
Q

What kind of stimulus do you need to remember to give during a sensory exam?

A

A null stimulus

152
Q

The knee reflex tests what spinal nerves?

153
Q

How is strength assessed (scale)? What is normal on this scale?

A

0 - 5 5/5 is normal. This means the patient can overcome your opposing movement

154
Q

Why do we screen for breast cancer?

A

It provides the greatest mortality reduction

Regular mammographic screening leads to the greatest reduction in deaths

155
Q

What are the ACR/SBI breast cancer screening guidelines for AVERAGE risk women?

A

Begin screening at 40 and then screen annual thereafter

156
Q

What are the ACR/SBI breast cancer screening guidelines for HIGH risk women?

A

Begin screening 10 years arlier than the youngest affected relative OR at age 30 - whichever age is later

Screen annually thereafter

157
Q

Women with a greater than 20% lifetime risk of breast cancer are elligible for what additional screen with their mammography?

158
Q

When should breast cancer screening cease?

A

When life expectancy is less than 5-7 years due to comorbid conditions

or when abnormal results would not be acted on due to comorbid conditions

159
Q

Who is at high risk for breast cancer?

A

Anyone with greater than 20% lifetime risk of breast cancer (based on family history, clinical factors)

Those with gene mutations or those of Ashkenazi Jewish descent

160
Q

What are gene mutations related to breast cancer?

A

BRAC1, BRAC2, CHEK2, P53, STK11, PTEN

161
Q

What views are taken during a screening mammogram?

A
  1. Craniocaudal view (CC) - compression plane is transaxial
  2. Medial lateral oblique view (MLO) - compression plan parallels the course of the pectoralis muscle
162
Q

How do you know you’re looking at a CC vs. an MLO view of a mammogram?

A

If you can see the pectoralis muscle then its an MLO view

163
Q

What is the difference between a screening exam for breast cancer and a diagnostic exam?

A

Screening exams are performed on asymptomatic females. They get two views done, leave the imaging center, and get a report within 30 days

Diagnostic exams are performed on patients with problems (mass, discharge, pain) or as follow-ups/additional imaging requests. Can include additional views or an US. Patient sees the breast radiologist before leaving the center

164
Q

What are you looking for on a mammogram?

A

Masses

Asymmetry

Calcifications

Distortion

165
Q

Is breast ultrasound used as part of screening?

A

No, only as part of a diagnostic exam

166
Q

What is the initial breast imaging study of choice for patients under 30?

A

Ultrasound

167
Q

What type of imaging is ALWAYS performed on a patient who presents with a palpable mass in their breast?

A

An ultrasound

168
Q

When is a breast MRI used?

A

In screening for high risk patients

Patients with biopsy-provden invasive ductal carcinoma or invasive lobular carcinoma

169
Q

What scale is used for breast imaging assessment?

170
Q

What portion of the BIRADs scale is related to screening only? To diagnosis only?

A

Screening: 0 - 2

Diagnostic: 3 - 6

171
Q

What is each level of the BIRADs scale?

A

0 = incomplete. Additional imaging needed (screening mammograms only)

1 = negative/normal breasts

2 = benign (no additional workup needed)

3 = probably benign (short-interval follow up recommended) Less than 2% malignancy

4 = suspicious (biopsy recommended - subdivided into 4a, 4b, and 4c) malignancy risk 2% to 95%

5 = highly suggestive of malignancy (biopsy or surgery recommended). Malignancy risk greater than 95%

6 = Known malignancy (biopsy-proven, treatment plan in place already)
