Test 72 Flashcards
Trendelenburg gait
when the HIP drops down as the IPSILATERAL foot is lifted off the ground
injury to the OCNTRALATERAL superior gluteal nerve (L4-S1 ventral rami)
injections into WHAT quadrant have a high probability of injuring the superior gluteal nerve>
Trendelenburg gait
Superomedial quadant
safest place for dorsogluteal ijections
superolateral quadrant of the buttocks
**MOST injections should target the ANTEROLATERAL gluteal area (von Hochstetter triangle) to minage possibility of nerve damage
heart condition that is considered a normal variant in 20-30% of adults
Foramen ovale
Any condition that raises RA pressure above left can produce right to left shunt> hypoxemia and paradoxical embolization
what is the most likely cause of SVC syndrome
mediastinal mass from the intrathoracic spread of BRONCHIOGENIC CARCINOMA>
compression of SVC>
impaired venous return from upper part of body
dyspnea
facial swelling
dilated collateral veins in upper trunk
SVC syndrome
arise at lung APEX
cause SHOULDER pain d/t compression of brachial plexus
HORNERS syndrome from involvement of cervical ganglia
Superior sulcus tumors (Pancoast tumors)
Morphine
opoid AGONIST
binds to MU opoid receptors
GPCR
Mechanism of Morphine
Morphine> binds MU> GPCR> activation of K channels> INCREASE in K efflux> HYPERpolarization of postynaptic neurons and termination of pain transmission
inappropriate laughter
increased appetite
slowed reaction time/motor speed
cognitive impairment
