Test 2 Flashcards
Increased density causes what type of X-ray
decreased penetration of the X-ray
UNDEREXPOSED, more white, RADIOPAQUE
-metal, barium, bone
Decreased density causes what type of X-ray
increased penetration of the xray, “burns it black”
more exposed, more black, RADIOLUCENT - air, fat, blood
4 views of xray
AP
PA
Lateral
Oplique
Typical CXR views
PA and Lateral
Typical Abdomen xray views
Flat and upright
Typical Extremity xray views
PA/AP, Lateral, Oblique
Why get more views on xray?
increases the sensitivity and increases chance of finding problem
> 10 ribs showing on xray
hyperinflation
if heart > 1/2 total width of chest
consider pericardial effusion, cardiomypathy, CHF
pediatrics are normally 1/2 size of chest
silhouette sign
loss of borders and landmarks on chest xray that indicated pneumonia
increased density occurs with infiltrates
How many lobes of right lung
3 - upper middle lower
How many lobes of the left lung
2 lobes - upper and lower
Where will Right Lower Lobe PNA present
consolidation with obscure the right hemidiaphragm
lateral view- infiltrated appear posterior to heart and obscure thoracic spine
Where will right middle lobe PNA present
right heart border will disappear and right hemidiaphragm is preserved
lateral- sits on the heart
Where will right upper lobe PNA present
right heart border will disappear
lateral view- infiltrates anterior to heart
Differential diagnosis for unilateral pleural effusion
Pneumonia
Pulmonary emboli
Neoplasm
Pancreatitis
Differential diagnosis for bilateral pleural effusion
CHF Collagen Vascular Disease Hypothyroid Fluid Overload Hypoproteinemia Nephrotic Syndrome Cirrhosis
Right verses Left pleural effusion
Right = cardiac Left = pancreatitis
CXR signs of hyperinflation (COPD)
flat diaphragm
>10 ribs visible
Increased AP diameter on a lateral xray
Haustral Marking
Indicative of large bowel obstruction, more peripheral located
Valvulae Conniventes
Look like stacked coins
Indicative of small bowel obstruction, more central
Metaphysis
Permanent bone
Epiphysis
The growth plate
Salter-Harris Classification - Type I
S-traight across, through the physis
Salter-Harris Classification - Type II
A-bove, into the metaphysis
Salter-Harris Classification - Type III
L-ower, into the epiphysis
Salter-Harris Classification - Type IV
T-hrough
E-verything
through both the metaphysis and epiphysis
Salter-Harris Classification - Type V
R-ammed, epiphysis rammed into metaphysis leaving no physis space
What is the eFAST?
extended focused abdominal scan for trauma
check chest and abdomen in trauma patients
Barcode sign
“barcode sign” indicates absent lung sliding on ultrasound and suggests the presence of pneumothorax at this interspace
A seashore sign is normal and means absent pneumo
Linear Probe
depth 9cm, more surface ultrasound views
arteries, veins, soft tissues, testicles
Curve Linear Probe
depth 30cm, can see organs
liver, gallbladder, uterus
Phased Array Probe
depth 35cm
heart, lungs, pleura, abdomen
ABCDE of assessing skin
Asymmetry
Border Irregularities
Color variegation (multiple shades)
Diameter >6mm
Evolution (changing in size, shape, color)
Melanoma
Most serious form of skin cancer
HIGH RISK:
- white males >50
- family or personal history
- total nevus count >25
- one or more atypical nevi
- young adult sun exposure with blistering
- tanning beds
- immunocompromised
- red hair phenotype
Basal Cell Carcinoma
Locally invasive and destructive. Increased risk for developing subsequent lesion
Most common in white caucasians. Usually on the face
pink or flesh colored, shiny/translucent, rolled border papule, can be ulcerated
Squamous Cell Carcinoma
2nd most common skin cancer behind BCC
Risk Factors:
- whites
- 45-75 yrs old
- high UV sun exposure
Can resemble aktinic keratosis- looks like a papule or plaque that can be smooth, hyperkeratotic, or ulcerative lesion. Most commonly on the neck and face
Merkel Cell Carcinoma
Affects older adults with light skin
rapidly growing, painless, firm nodule
blue/reddish nodule on head and neck region
Superficial Shave Biopsy
used for lesions of the epidermis and/or superficial dermis
-seborrheic keratosis, actinic keratosis, skin tags, warts, basal cell or squamous cell carcinoma
NEVER FOR MELANOMA or pigmented lesion
Deep Shave Biopsy
includes epidermis and some dermis
more often for basal cell and squamous cell biopsy
Punch Biopsy
Better cosmetic result than shave
for lesions involving the dermis, can close with stitches
Impetigo
“school sores”
Pain: itchy
Color: yellow pus-filled vesicles
Configuration: leaky pus/fluid
Location: mouth and face (child)
Dermatitis
Pain: itchy
Color: pink to red
Configuration: rash-like
Location: moist area
Eczema

Scarlatina
sandpaper-like skin, starts on trunk and spreads to extremities lasts 4-5 days
from strep.A
strawberry like tongue
Roseola
6th disease from HHV6 or HHV7
high fever followed by macules and papule on trunk that spread to extremities lasting 1-2 days
5th Disease
Parovirus B19
erythematous molar rash with circumoral pallor (slapped cheek rash)
acute arthritis in adults
by time rash shows up, patient is no longer infectious
What is the CAGE tool?
Used to assess potential problem with alcohol abuse
- Have you ever felt you needed to C-ut down on your drinking?
- Have people A-nnoyed you by criticizing your drinking?
- Have you ever felt G-uilty about drinking?
- Have you ever felt you needed a drink first thing in the morning (E-ye opener) to steady your nerves or to get rid of a hangover?
Suicide Screening Tool
- In the past few weeks, have you wished you were dead?
- In the past few weeks, have you felt that you or your family would be better off if you were dead?
- In the past week, have you been having thoughts about killing yourself?
- Have you ever tried to kill yourself?
___________________________________ - Are you having thoughts of killing yourself right now?
“Yes”to question #5 = acute positive screen (imminent risk identified). Patient requires a STAT safety/full mental health evaluation. Patient cannot leave until evaluated for safety
“No”to question #5 = non-acute positive screen(potential risk identified). Patient requires a brief suicide safety assessment to determine if a full mental health evaluation is needed. Patient cannot leave until evaluated for safety.
PHQ-9 Tool
- Patient completes PHQ-9 Quick Depression Assessment
- If there are at least 4 checks in the shaded section (including Questions #1 and #2), consider a depressive disorder. Add score to determine severity.
Consider Major Depressive Disorder - if there are at least 5 checks in the shaded section (one of which corresponds to Question #1 or #2)
increased score = increased severity of depression

Nonallergic Rhinitis
Typically afebrile with clear drainage and nasal congestion. No sinus pain
Perennial (all the time, not seasonal) allergens trigger

Primary Headaches
caused by overactivity or problems with pain sensitive structures in the head
- Cluster (awakens you in sleep, unilateral eye)
- Tension (band across head)
- Migraine (w/ or w/o aura) - pulsing sensation unilateral, sensitive to light and smells, nausea and vomiting common
-Cough headaches, Exercise headaches, sex headaches, alcohol (red wine), foods (w/nitrates), changes to sleep, poor posture, skipped meals, stress
Secondary Headaches
a symptom of a disease that activates the pain sensors in the head
- sinusitis
- aneurysm
- tumor
- concussion
- dehydration
- glaucoma
