Part 2 Flashcards
9 item format of abdominal sectioning
Left hypochondriac, epigastric, right hypochondriac, left lateral abdominal, umbilical, right lateral abdominal, left inguinal, hypogastric, right inguinal
Mediastinum definition
Wall of organs including heart, esophagus, thymus, trachea, and major blood vessels that separates the right from the left pleural cavity
Most likely place for a hip fracture of an elderly patient
The anatomical neck of the femur
Skier’s fracture mechanism of injury
Fracture of the fibula due to extensive weight being placed on it from confined mobility of boot while twisting and turning and managing skis, individuals can typically still walk down mountain despite pain because THE FIBULA IS NOT WEIGHT BEARING
The part of the talus that interacts with the tibia and fibula
The dome of the talus
The balls of the feet or the balls of the hand correspond to the…
heads of the metatarsals and heads of the metacarpals respectively
Large attachment site vs medium vs small on a bone terms
trochanter, tuberocity, tubercle
Great saphenous vein
Long superficial vein returning blood on medial side from foot, leg and thigh and emptying into the femoral vein at the level of the femoral triangle. Often this is harvested for a CABG
Important thing to remember when using the great saphenous vein in a CABG
Veins have valves, so it has to be oriented properly to allow blood flow
NAVL
The femoral nerve, artery, vein (hugged together within femoral sheath), and lymphatics (in the order lateral to medial) that travel together in the femoral triangle
Borders of the femoral triangle
The inguinal ligament, adductor longus, and sartorius
Saphenous branch of femoral nerve
Goes below knee, must be identified in ACL surgery and avoided cut to protect sensation in pockets on the leg
Femoral nerve origin and muscles it innervates
L2-4, innervates anterior thigh muscles such as quads, sartorius, and pectineus
Why don’t we lose blood flow to the glute area when sitting for prolonged periods?
The arteries perforate through the adductor magnus around to the back side at the adductor hiatus
Blood supply to vastus lateralis and what is the vastus lateralis often used for
Descending limb of lateral circumflex femoral artery, as an injection site IM
Trendelenberg gait
A result of paralysis or pareisis of the gluteus medius on the contralateral side causes swinging of leg around, remember glute medius helps by raising hip girdle on contralateral side
Sciatic nerve origin and components
Arises from L4-S3, tibial nerve which wraps around to innervate posterior leg, and common fibular nerve to innervate the anterior leg
Innervation of biceps femoris long head vs short head
Long head is tibial portion and short head is common fibular portion of sciatic nerve
Common finding on knee aspiration with an ACL tear
Middle genicular artery runs alongside ACL and tears with it so blood will be found, 1 of 6 genicular arteries
Name the 6 deep external rotators of the hip
- Gemelli superior and inferior
- Obturator externus/internus
- Quadratus femoris
- Piriformis
Adductor hiatus
Break in adductor magnus muscle to allow for passage of femoral artery and vein, changing names to popliteal
Pes Anserine
Attachment site of 3 different muscles, sartorius, semitendinosus, and gracilis on the medial lower face of the knee
The gastrocnemius is bi-articulate, meaning…
It crosses 2 joints
What are the 4 major types of laxatives
1) fiber and bulk forming agents
2) surfactants
3) osmotic agents
4) stimulant laxatives
Neuroimaging criteria for mild head trauma
GCS <15, suspected open or depressed or basilar skull fracture, >1 episode of vomiting, neurologic deficit, bleeding diathesis or anticoag use, seizure, >60 y/o, retrograde amnesia, intoxication or abnormal behavior
kidney stone size charting for passage
<5 mm manage at home, between 5-10 mm alpha blocker and outpatient assuming no other complicating factors for 4 weeks total, >10 mm urologic eval

…asthma exacerbations and increased asthma related mortality.
First line treatment for genitourinary syndrome of menopause (formerly vulvovaginal atrophy or atrophic vaginitis) in the absence of contraindications
low dose vaginal estrogen cream or insert or ring
4 cardinal features of parkinson disease
-Bradykinesia
-Rigidity (cogwheel), resistance to passive range of motion
-resting tremor
-postural and gait instability
Vibratory angioedema definition
Rare manifestation in a patient with untreated OSA and severe snoring that can result in anaphylaxis if untreated
1st line treatment for parkinson disease
carbidopa/levodopa
To extend the benefit of levodopa between doses in a parkinson disease pt, they can take one of these 3 medication types
-dopamine agonists (pramipexole, ropinorole, rotigitine)
-MAOI’s
-Catechol-o-methyltransferase inhibiors (-capone)
zonisamide (zonegran) drug class
Misc. Antiseizure agent
maxalt (rizatriptan) drug class
Triptan (serotonin 5HT1b1d receptor agonist)
psyllium (metamucil) drug class
Bulk forming laxative similar to fiber
Methylcellulose (citrucel) drug class
Bulk forming laxative similar to fiber
docusate (colace) drug class and MOA
surfactant laxative, lowers surface tension of stool allowing water to enter it and bulk it up
polyethylene glycol (PEG, miraLAX) drug class and MOA
osmotic laxative, pulls water into the colon from intestinal wall allowing for bulking of stool
What class of laxative is most concerning if abused and what consequences can occur
Osmotic laxatives, electrolyte derangement and overload issues in pt’s with cardiac or renal dysfunction
Lactulolose drug class
osmotic laxative
sorbitol drug class
osmotic laxative
List of the saline laxatives (2) and what mechanism do they work by? What is the most serious complication with them?
milk of magnesia, mag citrate, they are osmotic laxatives. Hypermagnesemia in pt’s without renal function
bisacodyl (dulcolax) drug class and MOA
stimulant laxative, alteration of electrolyte transport in intestinal mucosa and increase motor activity of intestines
senna (senoket) drug class
stimulant laxative
Triptan (serotonin 5HT1b1d receptor agonist) MOA
Bind vascular seratonin receptors in the cranial arteries that vasoconstrict reducing blood flow as the dilation of those arteries during migraine attacks often worsens pain
